Complex sales are the biggest of all sales. You have big commission dollars at stake. Sometimes, a salesperson’s entire year can be made or broken on one major sale. The problem is your competition wants that commission as much as you do.

If you want to win the big sale you’ve got to out-SELL your competition. The 10 keys to winning a complex sale tell you how.

In a complex sale, your goal is to identify the players who will be involved in a buying decision and help them see the unique value of your solution. Any decision-maker who you do not meet is a potential threat to winning the sale. This leads to the 10 keys to winning a complex sale. The more of these you do, the better your chance of winning the sale.

1. Before you deliver your sales presentation, meet with at least three people affected by the sale.

You need multiple sources of information. Winning a complex sale hinges on gathering information about how the decision will be made, who will make it and why. If you meet with only one person, how will you know if the information that person gives you is correct? Meeting with at least three people also helps you create greater momentum in the buying process - three people who want to buy from you are better than one. And it helps you better understand the customer’s needs. By the time you’ve met with three decision-makers, you’ll know if there’s someone else you need to meet with. Really good sales management training programs give incredible detail on the 10 keys to winning high-dollar, lucrative sales.

2. If the gatekeeper is not an influential person in the decision, get past this person as soon as
possible.

How? Ask the gatekeeper questions that he or she can’t answer. If the questions you ask are important to understanding the need, you’ll hopefully get the gatekeeper’s OK to find out the answers.

Offer to gather information from other people and report back to the gatekeeper with your findings.

Sell your gatekeeper on it. There may be benefits to the gatekeeper if higher level decision-makers get involved. One possible benefit is that the money to buy may come from someone else’s budget besides the gatekeeper’s.

If you do it early in a sales process, you may be able go over a gatekeeper’s head without asking for permission. This is more upsetting to the gatekeeper the closer you get to the decision. If a decision is about to be made, and you think you’re going to lose, going over the gatekeeper’s head sends the message that you are questioning his or her decision-making process. This is what is so upsetting to them. But if you go over the gatekeeper’s head early in a sales process, the gatekeeper has less invested in the decision, so he or she will likely be less upset by it.

3. Identify all the decision-makers and their positions on the team.

A few general questions to ask would be: How will your organization go about making this decision? Who else will you need to talk to?

To identify specific players on the buying team, ask these questions: Who’s budget is at stake here? (gets you the Virtual Authority). Who will be evaluating the technical aspects of this decision? (gets you the Integrator).

You’ll have no problem finding the User, and the gatekeeper usually finds you! And, you must find the Power Broker, so ask, “Who will be the key decision-maker on this?”

4. Finding the Power Broker before your competition does is crucial.

If the Power Broker wants to buy from you, your success is almost assured. If the Power Broker prefers your competition, forget it.

The Power Broker derives his/her power from credibility with the Virtual Authority, perhaps by being the recognized expert. Or, the Power Broker may be the Virtual Authority’s “right-hand person.”

Power Brokers tend to be strong-willed individuals who are goal-oriented and persuasive communicators - just like salespeople. An effective Power Broker is an effective internal salesperson. So, which member of the buying team is the most effective salesperson? Chances are, that’s your Power Broker.

5. Identify where each decision-maker is in the buying process.

Your sales approach with each player depends on where that person is with regards to the decision. Be a “doctor” with someone who doesn’t recognize a need. A prospect in the comparison stage needs to know why you are their best choice, how you are different from the other options, etc. So, you want to be a Coach.

Think of the roles as “selling hats.” Which hat you wear depends on where each prospect is in the buying process. When a player moves in the buying process (hopefully forward, but possibly backward) change your selling hat to meet their new needs. The speed with which each buyer’s wheel turns determines how fast you should change your selling role.

6. After each meeting with a prospect, send that person a letter stating your understanding of their needs.

You cannot rely on verbal communication alone, because selling the person sitting in front of you is not enough. You must also provide your prospect with the tools needed to sell other decision-makers on your behalf. And since most sales literature focuses on your product’s features and benefits, not on your customers’ needs, they’re ineffective as a leave-behind.

Your letter of understanding will reinforce the importance of the meeting for your prospect, solidify why the need is important, and provide information your prospect will need to sell other decision- makers.

7. Develop as many sponsors for your cause as possible.

Think back to the biggest sale you’ve ever made. Chances are, there was at least one person in your client’s organization who wanted you to win the sale.

A sponsor is any decision maker who wants you to succeed. Think about a complex sale you’re working on now. Is there any decision-maker in there to wants you to succeed? If not, what can you do to develop one (or two)?

8. Find your enemies and neutralize them.

While you are cultivating sponsors for your cause, your competitors will be busy developing sponsors for their counterattack. The biggest threat to your winning a complex sale is the existence of an individual who wants your competition to win.

The most successful strategy is to neutralize that person by being proactive. Identify who is against you, assess that person’s power influence on the decision, and take action to defuse the threat. Don’t sit back and wait!

Sometimes, your enemies are difficult to recognize. They may not want you to know they exist. These people may say wonderful things about you to your face, but as soon as you leave, they begin pulling strings to make you lose. Once again, having multiple sources of information is the key to identifying these stealthy adversaries. Ask your contacts, “Is there anyone who may be opposed to this?”

To neutralize your enemy, try overwhelming them with superior numbers. If you can develop several sponsors among the members of the complex buying team, you can create enough momentum for your solution to overpower the enemy’s opposition.

How much credibility does your enemy have with other members of the Complex Buying Team? If your answer is “a lot,” try to meet with your enemy one-on-one. Ask questions such as “What concerns might you have about our solution?” Apply the sales role of a therapist and try to draw out their concerns.

Don’t underestimate the importance of personal agendas. The best supplier with the best offering does not always win. Suppose you made a sale to Department A that was successfully implemented. Now you’re trying to make a similar sale to Department B. If department A’s manager is at odds with the manager of Department B, you may lose the sale to B because you were successful with A.

9. Develop a complex sales strategy by answering these three questions:

What factors are working for you in this sale? What factors are working against you? What can you do better position yourself to win?

10. Don’t get overconfident!

The greatest barrier to winning the sale may be you! Overconfidence about how a sale is progressing may lull you into a false sense of security. Always question your basic premises. Francis Bacon said, “If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts, he shall end in certainties.” Don’t assume anything!

Winning a complex sale is difficult. Your competition wants them as much as you do. Winning is no accident. The salesperson who wins will likely be the one who works just a little bit harder than the others, who does a few things that other salespeople don’t do.

Work harder and apply these ideas. Attend a sales training course and you WILL close more large-dollar, complex sales. You can bet on it!

How long will we continue to fool ourselves into believing that a casino, bar, or pub can twist our social and ethical values? Come on, it’s time to face the reality! Human beings have the capability to think, analyze, and decide what is right and what is wrong. Therefore, it is us who are accountable for degrading or upgrading our social and moral values. The fact is that a casino is like any other workplace; it provides jobs to thousands of out of work people. Therefore, in a place where more than 20 percent of the populace is jobless and their only ray of hope is a casino, contemplating on the impacts of a sturgis casino just does not seem right. You see, there are always two sides of a coin; it is up to you to figure out what is more significant for the society.

Another thing that you clearly need to distinguish is the variation between speculation and fact. The point that a casino can infect the area and devastate social and moral values of a civilization is pure speculation. It is a subject that can have never-ending debates without any conclusion. However, the fact is that thousands of citizens are unemployed in an area and do not have money to buy one square meal. The fact is that these people have not seen happiness for a long time. The fact is that these people hate themselves for not being able to fill their children’s stomachs. The fact is that these people die a slow death everyday and do not want tomorrow to come. The fact is that these people weep everyday when they are alone. The fact is that these citizens crave a job and crave to live just like you do. Is that asking for too much? Taking into account these specifics, how can citizens block their only beam of hope? In a position where there are no other means of earning money, stopping a casino from being built is not acceptable.

Come to think of it, the construction of a sturgis casino can generate 1000 to 1200 temporary jobs. After the Sturgis Michigan casino is constructed and is operational, it will provide anything between 2000 to 2400 permanent jobs. How does this make the casino a culprit? In fact, it is a blessing in disguise to all the jobless individuals who are in desperate need for money. Can you be cruel enough to oppose the building of a casino and deny these unemployed people of the only source of revenue? Can you be self-centered enough to consider the social impacts of a casino far more essential than the feelings of all the unemployed citizens? Thinking just about us is something that each and every person does. Let us take a step ahead and think about all those jobless people who want to live a normal life just like we do. Let us help them in getting a job so that they can fill their stomachs everyday. Let us bring smiles to the faces of all our unemployed neighbors. Let’s do it this time.

Tumbling media is any material that is used for modifying or shifting the look of a part – that is cleaning, polishing, smoothing parts and separating parts. Tumbling media are coarse in nature. Tumbling compounds are compounds that are used in the tumbling process as aids.

The tumbling media is also identified as finishing media as it is used to offer the final touches to parts. The parts to be polished or cleaned or separated are put into tumbling or vibratory machines along with the tumbling media. When the equipment start to run, the tumbling media and the parts rub adjacent to each other which supply an abrasive accomplishment. This act in turn gives the smoothing and polishing outcome. There are two types of tumbling media – natural and artificial. Natural tumbling media include corn cob media and walnut shells media. Corn cob grit is used as tumbling media as it has effective abrasive and cleaning properties. Walnut shells are also powdered to different grit sizes and are used in cleaning and polishing. The advantage of tumbling media is that they are bio degradable and hence are environment friendly. They are also tough and cost effective. They are typically used in tumbling processes where soft abrasive property is needed.

Artificial tumbling media includes plastic finishing media and ceramic media. Both come in preformed shapes and sizes. Depending on the requirement, the right material, shapes and sizes can be chosen. Plastic tumbling media is found to be ideal for metal removal, pre plated finishing, fast and heavy cutting. It is used successfully on metals like brass and aluminium which are soft metals. They are also ideally suited for use on stringy materials because they avert burrs rolling over into holes. Plastic media are first-rate for providing very smooth finishes without much shine. Ceramic tumbling media is suited for light as well as heavy deburring and in aggressive removing of hard metals. Ceramic media come in extremely small sizes and they work better than plastic media on heavy parts.

Tumbling compounds are practical in improving the effectiveness of tumbling media as they prevent glazing over. They also offer additional abrasiveness and help to uphold the metal colour of the parts being tumbled. They also help in imparting an anti rusting and anti corrosive properties to the parts apart from giving shiny and bright finish. They are very helpful while cleaning of parts – in de-scaling and heavy grease removal. They offer a medium that ensures that the cleaned grime does not get re-deposited on the parts. They also support in the deburring method and separating of parts. Tumbling compounds are also good for using with delicate parts as they act as good cushions.

Tumbling compounds might be dry or wet or creamy. They can be ph-balanced, acidic or alkaline in nature depending on the function they are projected to serve in the finishing process. The flow rate of the tumbling compounds has to be maintained in proportion to the volume of the tumbling media used in order to achieve optimum fin

The finish of a product speaks volumes about it and hence it assumes a lot of importance. How to achieve the best possible finish? Using walnut shell media and corn cob media and finishing compounds, of course! Finishing media and finishing compounds as the names suggest are materials used for providing the desired ‘finish’ or ‘polish’ to an object or part using vibratory finishing machines and centrifugal barrel machines and more.

Finishing compounds come in 2 main varieties – wet compounds and dry compounds. There products for different purposes including cleaning, rust proofing, burnishing, colouring and ferrous cutting. These finishing compounds also come in standard packaging sizes of 5 gallons and 55 gallons. Dry finishing compounds (which are in powder form) are typically used in burnishing, colouring, cleaning and cutting. BC-311 produces heavy lather and is used in tumbling barrels for burnishing all kinds of equipment like deburring machines and centrifugal barrel machines. Mass finishing can be best described as processes in which a number of parts are simultaneously finished. The mass finishing involves burnishing, deburring, cleaning, removing rust, polishing etc of the parts. The two main types of mass finishing are tumbling barrels or barrel finishing and vibratory finishing machines.

Mass finishing is an art while being a science because the processes involve random action. The mass finishing process could be organized as batch processes, continuous processes or sequential processes. Media are used in mass finishing to accomplish one of four things - cut, luster, parts separation and scrubbing of surfaces. The media could be aluminium media, preformed walnut shell media, preformed resin bonded media, preformed shapes in steel, synthetic random shaped media, natural media in random shapes like rocks, corn cob media, ceramic etc. Vibratory finishing machines are used in the vibratory finishing machines process. This vibratory finishing machines process involves using components like water, finishing media and finishing compounds. Vibratory finishing machines are designed to produce highly smooth surfaces and can act inside deep cavities like tubes. It can be used on varied parts - for delicate parts or large surfaces, which may not be possible in a tumbling barrels process. Loading and unloading vibratory finishing machines is easy. They also have the advantage of lesser cycle times, better cleaning and better color maintenance. Vibratory finishing machines typically do not have speed control; however, a few of them do. The usual speed is 1700 vibrations per second; for lesser speeds, the parts may sink to the bottom making the finishing process less effective. Vibratory finishing machines work at optimum level when they are between 75% and 90% full. Three parts walnut shell media to every part metal can be used for delicate parts.

Finishing media and finishing compounds can be defined as material that are used to remove sharp edges and burrs from parts to make them smooth and provide a good finish and polish effect. There are deburring machines, vibratory finishing machines, mass finishing machines, tumblers and spinning machines among others that are used to produce the finish. The finishing compounds and corn cob media are used in these machines for varying periods of time to give the desired finish or polish.

Corn cob media come under the dry finishing media type. It is treated corn cob media that is powdered to different dimensions depending on the finish requirements including vibratory finishing machines. They can be used to achieve very fine finishes in the 1 Ra range and meet any requirements for a decorative finish. Corn cob media is environment friendly as it is made from the hardened cob ring and is organic in nature. It has the advantage of being capable of use in tumbling barrels and vibratory finishing machines and can absorb oils, grease and dirt. It can be used to dry parts while keeping their surface safe. Corn cob media also finds use as a burnishing grit for soft metals like brass and bronze. The weight and type of the part to be finished determine the size of the corn grit in the corn cob media.

The corn cob media are re-usable and long lasting as they do not break down easily. Deburring machines is the process of removing jagged edges or protrusions from parts, mostly wooden and metal parts. Deburring machines are used to accomplish the process of deburring. Primarily two types of deburring machines used – tumbling barrels or centrifugal barrel machines and vibratory finishing machines. Tumblers are used for mass finishing of parts. They can be used for wet as well as dry finishing. These systems are well suited for fast and efficient deburring of plastic and metal parts or components. There are models that are available in different sizes from compact bench models to big barrels that can be fixed on floors. Tumbling barrels systems are very important deburring machines in use. They are typically used where heavy deburring is required. Barrels are ideal for heavy loads. Dry tumbling barrels is used when delicate deburring machines are called for and produces a smooth finish. Wet barrelling is used for metal processing to remove excess material as well as to provide a polish.

Vibratory deburring machines are also used for mass finishing. They function by shaking or vibrating the processing vessel, which causes the walnut shell media and parts to scrape against each other thus accomplishing a deburr and producing a polish. These deburing machines are precise and can deburr even recesses in the parts and hence they are very well adapted for delicate and intricate components. They can also be used on large surfaces because they have very short strokes and high speeds. These centrifugal barrel machines can be automated quite easily compared to tumblers. Walnut shell media come under the category of dry finishing media. The walnut shell media can be used in cleaning and finishing applications. They are ideal for tumble finishing of metals like brass, bronze and aluminium. Walnut shell grit finds use in oil well drilling, to keep the circulation going. Walnut shell media is made by crushing the walnut – it is hard and fibrous in nature. They are long lasting, angular and have many faces. They are mildly abrasive. The main advantage of walnut shell media is bio degradability. It is there fore environment friendly and non toxic. It can be reused many times over. It suits both tumbling barrels and vibratory finishing machines and reduces finishing operations time substantially.

Building traffic using the popular exchange sites

( Attention - Landlords, tenants, and roommates can find a nice Flat House Share )

The following article lists some simple, informative tips that will help you have a better experience with website traffic.

Those of you not familiar with the latest on website traffic now have at least a basic understanding. But there’s more to come.

Traffic Exchange Sites are websites where you get page views of your own site in exchange for visiting others. Many such sites are available. However, choosing the right one or a combination of them can be a very time consuming process.

Basically there are two types. Manual surfing and Auto surfing. Some Traffic exchanges cater for Manual surfing only, some cater for Auto surfing only and some cater for both.

Manual surfing - This requires your input by clicking a button after a specified time period, generally 15, 20 or 30 seconds, although there are a few other variations. With manual surfing, the surfer is expected to view each site. However, with most exchange sites, it is possible to minimize or resize the windows. This defeats the purpose because it allows multiple sessions to be run simultaneously. On the better exchange sites, security measures are often used to deter this. These are normally random prompts that require user input. For example, after x number of page views, you may be required to enter a code, select a color or image or perform some other variation of this.

Auto surfing - This requires no input. However in reality, your input may be required because of popup or frame breakers. Some traffic exchange sites require that the pages run are maximized and although you can minimize the page yourself, it will automatically maximize at the next refresh. You will also find that with some exchange sites, pages will run on top whereas with others, pages will run quite happily underneath, allowing you to do what ever you like without ever viewing the page content.

Both manual and auto surfing will bring traffic to your website, but there is a much greater likelihood of your web pages being actually seen with manual surfing.

Credits - As well as surfing, credits are usually acquired for subscribing, for referrals and for any winnings associated with exchange site lotteries, games or competitions. These credits can then be used to increase the traffic to your site. Some exchange sites will also allow you to sell your credits to other members.

Free or Paid - The majority of Traffic Exchanges offer a paid option. This option may give you a better surf ratio, bonus credits, money for referrals or other benefits. Before paying however, it is important that you test how targeted the traffic is that you receive. There’s no point in paying for extra traffic if it doesn’t generate any more income for you.

Click for Credits or Buy Credits - Is it worth buying credits?

This can depend on a number of reasons. The two main ones are time and money.

Let?s take an example

At the time of writing the cost of 2000 credits for free members of a well known Traffic Exchange Site was $40. This works out at $0.02 a click. For pro members the same $40 bought 2200 credits.

With the number of clicks limited to 250 per day and page views of 20 seconds this means that in theory it will take you 250 X 20 = 5000 sec or 83 minutes 20 seconds to view the 250 pages. However in practice you must allow extra time for clicking the next button, clicking the title of the page you will be viewing and any sites worth looking at.

Since I am a firm believer in practical results, I viewed the 250 pages. It took me 2 hours and 12 minutes to accomplish this. During that time, I accumulated 854 credits. To buy these credits would have cost $17.08 as a free member and approximately $15.53 as a pro member. Allowing for rounding up, this equates to almost 390 credits per hour or $7.80 per hour cash value.

Now ask yourself this. Would you work for $7.80 per hour?

I must emphasize that this is only one example and that other results will differ because of the random allocation of credits. It is shown here only as an example and to give you an idea of the cost implications for one particular traffic exchange site. The cost of credits may differ dramatically for different exchange sites. If you buy or intend to buy credits from a traffic exchange site, you can apply what is shown in the example. There’s no need to click on a large number of websites to find out if your exchange site is giving you enough credits for your money. A sample of around 20 sites should give you enough information to produce a rough value-for-money guide.

If you enjoy this sort of thing or want a break from train spotting, you could expand on this. Increase your sample size, increase the number of samples, select a good representation of traffic exchanges and tabulate your results. Choose enough sites and you will be able to create your own league table. There?s a market for everything.

Whether you use traffic exchange sites or not in the quest for more visitors to your site, you should at the very least know what they are and what they do. But don’t totally dismiss them. They are part of an expanding market. I recommend that you try at least one traffic exchange site. You could read every book on the subject, but without active participation, you will not be qualified to comment on their worth or suitability. The time taken for a few mouse clicks is a small price to pay. If it works for you, you have learned. If it doesn’t work for you, you have learned.

When word gets around about your command of website traffic facts, others who need to know about website traffic will start to actively seek you out.

Finishing media is used in the practice of finishing of parts. When the parts are loaded into the finishing machines – tumbling machines and vibratory finishing machines – along with the media, they rub with each other. The media has an harsh property which results in deburring, smoothing, polishing and cleaning of the parts. Finishing compounds may be used for the duration of the finishing practice to increase the effectiveness of the finishing media. Finishing media can be generally classified into two categories. One is natural media like corn cob media and walnut shell media. The other category is simulated media like plastic deburring media and ceramic finishing media.

Corn cob media is prepared by grinding the solid wooden ring of the corn’s cob. It is prepared into an coarse grit that can flow smoothly. Because it is natural, the corn cob media is environment friendly. This media is suitable for use with both tumbling and vibratory machines. It has great absorbent properties which makes it ideal to clean and dry parts. Corn cob grit can absorb oils, grease, dirt and moisture without causing a scratch or damaging the surface of the parts in any manner. It is excellent for use as a burnishing agent and is used for burnishing of metals in tumbling machines. Metals such as brass and bronze which are soft in nature get the desired finish with this media.

The corn cob media grit comes from coarse variety to super fine variety to suit a variety of parts, based on their weight and nature. This media is tough and does not break down easily; It can be reused again and again and it cost effective. It reduces the cycle time of finishing operations. It is clean and can be incinerated and poses no health or environment danger. It has a soft abrasive action and can be securely used on fragile components to protect micro finishes. It is effective on both metallic and plastic parts.

Walnut shell media is another popular natural finishing media. It is prepared by grinding walnut shells that are tough and fibrous into grit – the grit sizes could be large or small based on the requirements. The nature of the parts plus the perforation size of the screen that is used to separate the parts from the media after the finishing process is over determine the grit size. Walnut shell media is also used in blasting machines apart from tumbling and vibratory machines. They are ideal to de-flash plastic parts and polishing and smoothing of metals like aluminium, bronze and brass.

Walnut shell media also comes in handy in oil drilling to avoid clogging during circulation and to impart anti-skid properties to paint which is used about swimming pools and walk ways. This media is angular and multi faceted. It lasts long and is reusable. Being natural, it is non toxic and environmentally secure. It is a soft abrasive that can preserve the primer coat while removing the top coat of paint from parts. It serves to progress the cycle time of the tumbling or vibratory finishing procedure.

Mass finishing is a terminology used to identify the procedure of deburring, cutting, smoothing, polishing, cleaning and separating of parts as a group. This procedure involves the loading of parts to be finished into finishing machines like the tumbling barrels , vibratory machines and centrifugal barrel machines. Along with the parts, finishing media and/ or finishing compounds can also be loaded with or without water. Once the finishing machines starts execution, the parts graze alongside the media while being suspended in the finishing compounds. The media and compounds have coarse properties which cause the excess metal (or any other material with which the parts are made) to be abraded away.

The manner of mass finishing might use tumbling machines that are barrels which are prepared to swivel or vibratory machines which are tubs that quiver at very high speeds with short strokes. The finishing media used might be natural media like the corn cob media and walnut shell media or imitation media like plastic deburring media and ceramic media. While natural media present soft abrasive action on the parts, the artificial media are used for intermediate to heavy deburring. Plastic media being lighter compared to ceramic media are used with delicate and fragile parts while the ceramic media is used with heavy loads that need cutting. They come in all sorts of shapes to handle different sizes and patterns in the parts being finished like conical, pyramidal, cylindrical, triangular and so on.

Finishing compounds are used in the mass finishing process to increase media efficiency. They give additional abrasive property and more cutting power. They prevent glaze formation in the loads so that the media can work better on the parts. These compounds could have alkaline or acidic properties and come in the liquid, powdered or cream forms. When cleaning of parts is needed during the mass finishing, compounds come in very handy. They are good cleaning agents that can degrease, de-scale and de-oxidize. They can also be used to impart properties like anti-rust and anti-corrosion in the parts by using certain chemicals especially for this purpose.

Centrifugal barrel machines are finishing machines used in finishing of parts. They typically have one or more barrels mounted on turrets. These barrels are made to rotate at very high speeds so that the principle of centrifugal force comes into play inside the barrels. The load in the barrels is thrown to the walls of the barrel because of the centrifugal force that acts on them at the barrel center. The parts and media that have been put together thus rub with each other continuously at a very high rate of speed producing the desired deburring and cutting action.

The centrifugal barrel machines take less time to finish parts as compared to standard barrels or vibratory machines. They have safety latches to keep the loads safely inside when rotating. They are easy to load and unload. Centrifugal barrel machines come in different capacities, different horse power for motors, electrical powers and shipping weights to suit different finishing operations.

Deburring machines or finishing machines are used in the manner of finishing of parts. The parts to be finished, finishing media and finishing compounds are all loaded into the deburring machines. When the machine starts, the media and parts scour with each other; the media’s abrasive action produces the deburring and polishing that is required. The finishing compounds are there to boost the media efficiency.

The foremost types of deburring machines are tumbling barrel machines and vibratory finishing machines and they are the most frequently used. There are other machines also like the centrifugal barrel machines and blasting machines that are used for explicit cases. Barrel machines are best when heavy loads are to be run and these machines give optimum performance when they are run with 50% full load.

There are wet barrel machines and dry barrel machines. Wet barrels are used most generally; they are used for the removal of excess material from parts and also for polishing. Water and finishing compounds are used with these machines to polish, clean and deburr parts. Wet barrels work fine on metal parts and they can also be used for dry finishing operations.  Dry barrels are used in mass polishing and deburring in plastic as well as metal parts. No liquids are used in these machines. They come in useful in factories where large quantities of water are not readily available. Dry systems work well on frail parts as the environment inside the dry barrel is very protected. The finished parts typically have a hand buffed appearance when they emerge from the dry machines.

In blasting machines, media are blasted to hit against the parts that are to be finished which causes a deburring and cutting effect. In centrifugal machines where the load in the machine is rotated at very high speeds, the load goes to the wall of the machine and the parts and media rub very forcefully with each other – this in turn produces a deburring and polishing effect.

The vibratory finishing machines have a processing vessel also known as a finishing tub to load the parts, media and finishing compounds. A shaft mounted on to the tub produces the shaking action. This tub is shaken at a high rate of speed but with very small strokes. So, these machines while reducing the cycle time of the finishing operation considerably are very soft on the parts. Even fragile components can be finished securely in a vibratory finishing machine. These machines provide a precise and complete cutting action. They are perfect for removing material from recesses in the parts like for example a bore. Because of their short stroke, they are well equipped to handle bulky parts like wing spans without the hazard of causing any damage to them. Another key advantage of vibratory finishing machines is that they can be easily automated either fully or partially and human intervention can be reduced to a great extent. There fore they can be used in a batch processing mode or a sequential mode.
