Vibratory Finishing F.A.Q.s

Question: What will vibratory finishing do to my parts?
Answer: Many different finishes are possible using vibratory processing. Simple de-burring, pre-plate finsih condition, reflective finish condition, cleaning, de-scaling, edge rounding, finish moderation, and other finish conditions are possible with vibratory finishing.

Question: What is media?
Answer: Media is a "buzz" word for the material used in a vibratory machine to interact with your parts to achieve the finish condition desired. Media is available in a multitude of abrasives and non-abrasive ranging from man made ceramics with aluminum oxide or silicon carbide through porcelain and steel burnish forms to materials such as corncob and walnut shell.

Question: How many parts can be processed at a time in a Burr King vibratory machine?

Answer: Depending on the size, weight, geometry, material and surface condition desired it is possible to process many parts at once within a Burr King vibratory machine. Burr King vibratory machines are capable of processing from a few pounds to several hundred pounds of parts per process run depending on the model employed.

Question: What function does the physical properties of the vibratory tub shape play in part processing?
Answer: The physical properties of a vibratory machine are important considerations when selecting the ideal machine for your parts. The machinery must be designed to deliver fast, energetic, and controlled vibration to your parts. The vibratory chamber should protect your parts during the vibratory cycle. The vibratory system should be able to operate wet or dry based on your finish needs. The vibratory system should be able to accept the finishing media required achieving the finish you require in the time frame demanded. Importantly, the vibratory machine whould fit well in your shop while not intruding unneccessarily, annoying your employees, or disrupting the other machinery such as CNC machines and other high precision units. Burr King vibratory machines are designed to offer a wide variety of capability tailored to your particular needs, all are well suited for most shop environments, and all are specifically designed not to adversely affect the operation of neighboring equipment. Contact your Burr King distributor or the Burr King factory for guidance.

Question: What actually does the work in a vibratory machine?
Answer: The machinery delivers mechanical energy to the media, compounds, and parts to achieve the desired finish. The media abrades, burnishes, or polishes the part as driven by the machinery. The compounds keep the media in good condition, lubricate the parts to improve finish, flush media slurry and metal fines out of the vibratory chamber, and treat the part finish for color, and/or corrosion resistance.

Question: Does media wear out?
Answer: Yes, all media has a definitive service life. The length of life is determined by the equipment, part finish results, proper compound usage, and the extent that the media lodges in part cavities, if any.

Question: What becomes of the vibratory media waste and material fines that are created in a vibratory process?
Answer: Waste should be flushed through the system using what is commonly called "compound flow-through". Most Burr King vibratory machines include a "compound flow-through" system. Burr King recommends that a compound filtration system be used whenever wet processing is done. Burr King's FilterPAK 4000 fluid filtration system is an inexpensive addition to any vibratory system. Using the FilterPAK 4000 will extend media life, improve part finish, maintain a cleaner machine, keep your parts cleaner, and provide collection for ready disposal of media slurry and material fines.

Question: Can a low RA or RMS finish be achieved using vibratory processing?
Answer: Yes, with the proper selection of media, compounds, and machine many finish conditions are possible. The particular part and its pre-process condition are important variables for achieving your desired finish condition.

Question: Is vibratory processing difficult to control?
Answer: No, once the optimum process is defined you can expect consistent output provided the process inputs are maintained in reasonable bounds.

Question: How are parts introduced into the vibratory chamber?
Answer: Parts may be hand or conveyor introduced.

 Question: How are parts extracted from the vibratory system?
Answer: Generally parts are readily extracted by hand. Extraction can be aided using separating screens and other simple tools. Burr King's VibraKING 40 large bowl system incorporates AutoSEP Automatic part extraction. The VibraKING 40 can be incorporated in continuous processing using the programmable logic computer (PLC).

Question: What are vibratory process inputs?
Answer: Vibratory process inputs include media, compounds, machine condition, process time, load size, and incoming part condition.

Question: What is the largest part that can be processed in a Burr King vibratory machine?
Answer: In general vibratory tubs will process parts that are not longer than 1 inch less than the interior tub length dimension. The other dimension (front to back) should be less than 75% of the tub interior front to back dimension. The part size limit of vibratory bowls is generally limited to about 75% of cord dimension of the bowl taken at a point 1/2 the distance from the interior hub and the outer wall. The front to back dimension at the cord length limit is generally limited to 50% of the distance between the interior hub and the outer wall. Sound complicated? It can be! Take the easy way out and ask Burr King to eveluate your particular part.

Question: Can the Burr King vibratory chambers be divided into sub-compartments?
Answer: Yes, generally tub systems can be divided into up to four sub-compartments. Dividing the chamber is a handy way to extend the versatility of your vibratory machine.

Question: How much time will my parts require?
Answer: The length of time to process your parts will be dependant of the condition of your parts pre-process, and other process inputs like media, compounds, machine style, etc. Burr King offers test process of your parts to identify the necessary process parameters including process time. There is no charge for this service and we recommend that new adopters of vibratory processing use it prior to product purchase.

Question: What is done with vibratory waste that may be developed?
Answer: Unless your material has toxic character as might be identified with heavy or exotic metals, most often vibratory waste can be disposed of in common land fills. Burr King recommends that you consult with your local authorities to best answer this question. Burr King provides MSDS sheets on request for all vibratory consumables we sell.

Question: Are Burr King vibratory machines available in international electric power configurations?
Answer: Yes, all Burr King products will operate, or may be adapted to most AC main voltages and frequencies. Please consult with our factory. All are available in popular 60-hertz power options.
