Metal Finishing FAQ

Rinsing & Separating Systems

Q: Are Compound B or Compound D & water the only fluids that should be run through the rinsing systems?

A: No, any other manufacture's compounds are all right to process.

Q: What is the rate of flow for the rinsing systems?

A: The flow rate is fully adjustable.

Q: Can the rinsing systems work with any of the tumblers that have drainage ports?

A: Yes, these will work with any of the models TV-10 up to AV-75

Q: Are larger tanks available for the rinsing systems?

A: No, we do not have any larger tanks available.

Q: How do I best maintain the recirculating pump for optimal life?

A: Be sure to clean the receiving tank daily for optimal life.

Q: How do I best maintain the recirculating pump for optimal life?

A: Be sure to clean the receiving tank daily for optimal life.

Q: Can I use the MS-75 with tumblers other than the Tumble Dump style?

A: Yes, many other manufacturers recommend our separator, normally up to 3.0 cu ft size machines.




Tumbler FAQ’s

Q: How do determine if I need a vibratory tumbler, a magnetic finisher, or an oblique machine for my application?

A: The best way to begin is to identify your individual needs, including what you need the finisher to do, the type of material that requires finishing, and the volume of the load.

Q: What are the general features of the various tumbler models?

A: The smaller models, TV-5 & TV-10, are best suited for light deburring and polishing and can be used with wet or dry media. The Dri-Polisher, as its name implies, should only be used with dry media. The TV-5 & Dri-Polisher are the only models that do not have drains, all other models are equipped to work with the strainer assembly and rinsing systems. Do not use the TV-5, TV-10 or the Dri-Polisher with steel or ceramic media.

The Adjusta-Vibe models (up to .75 cu ft) are ideal for heavy deburring, flash removal and polishing, this includes the AV-18, AV-25, AV-40 and AV-75. The Tumble-Dump models are also suitable for heavy deburring and polishing, with the added ability to quickly and easily unload by tilting the bowl.

If you require a machine (2.5 cu ft) that will handle deburring, descaling, flash removal, cleaning, polishing and burnishing, the AVT-250 would be your best choice. The addition of the MS-75 Separator will save time by separating parts from the wet or dry media.

Very small, complex, non-ferrous metals, in need of burnishing and polishing, would be suited for our CMF Magnetic Finishers.

For light deburring, polishing and burnishing of flat parts, an Oblique (Open End) Tumbler may be ideal for your application.

Q: What are the capacities to the various tumblers?

A: The capacity of each tumbler model is:

  • TV-5 .05 cubic feet
  • Dri-Polisher .12 cubic feet
  • TV-10 .10 cubic feet
  • AV-18 .18 cubic feet
  • AV-25 .22 cubic feet
  • AV-40 .35 cubic feet
  • AV-75 .75 cubic feet
  • AVT-250 2.5 cubic feet

Q: Can I use a different size bowl on a base without a problem?

A: No, the tumbler is designed to function properly only with the specific bowl. A smaller or larger bowl will cause damage to the motor.

Q: How long should I run a tumbler?

A: Tumblers are designed to be run 10-12 hours a day.

Q: Can all tumblers use either wet or dry media?

A: The Dri-Polisher is suited only for dry media. All other models may be used with either media.

Q: Can I use steel shot in the tumblers?

A: You may use steel shot the models AV-18, AV-25SS & AV-40SS only.

Q: How much media do I use?

A: To determine media capacities, multiply the media density (found with each individual media listing) by the cubic foot capacity of the tumbler (found in the individual tumbler listing). Examples are listed below. Note this is the total media capacity only and actual media amounts will vary in direct proportion to the amount of parts being tumbled.

  • Ceramic (90 lbs/cu ft) in a TV-10 (.10 cu ft).
    90 x .10 = 9 pounds of media.
  • Porcelain Balls (125 lbs/cu ft) in an AV-40 (.35 cu ft).
    125 x .35 = 43.75 pounds of media.
  • Ceramilite (65 lbs/cu ft) in a TV-5 (.05 cu ft).
    65 x .05 = 3.25 pounds of media.
  • Plastic (55 lbs/cu ft) in an AV-75 (.75 cu ft).
    55 x .75 = 41.25 pounds of media.
  • Plastic (55 lbs/cu ft) in an AV-18 (.18 cu ft)
    55 x .18 = 9.9 pounds of media.
  • Dri-Shine III (30 lbs/cu ft) in a Dri-Polisher (.12 cu ft).
    30 x .12 = 3.6 pounds of media.



Rotary Tumbler FAQ’s

Q: What is the best application for a Rotary Tumbler?

A: Flat parts respond very well as compared to all other methods, as well as burnishing medias.

Q: What type of media can I use in a Rotary Tumbler?

A: You may use the same medias as with a vibratory tumbler.

Q: What size parts can I tumbler?

A: You can tumble up to 25% of the tumbler capacity provided parts are free-floating.

Q: What is the diameter of the bowl opening?

A: The Model 500 has a 2.5" opening; the Model 1000 has a 4.5" opening.

Q: Can I use liquid or dry compounds in a Rotary Tumbler?

A: Yes, they are required just as in a vibratory model.

Q: What type of surface should I use the tumbler on?

A: The Oblique Tumblers should be used on a flat, non-skid surface.

Q: How long can I let the tumbler run?

A: These may be run 24 hours a day in a well ventilated area.




Finishing Systems FAQ’s

Q: What size parts can the AVT-250 handle?

A: The parts can be 3 to 4" blocks & shafts up to 16".

Q: Can this be used with a dry media?

A: Yes

Q: What is the voltage required for the AVT-250?

A: 115V, 15 Amp.

Q: How difficult is it to change out the AVT-250 for another use?

A: This can be accomplished in minutes using the discharge port.

Q: Why would I use a System 75 over the AVT-250?

A: This would strictly depend on the capacity needed.




CMF FAQ’s

Q: Who is most likely to use a Magnetic Finisher?

A: A Magnetic Finisher is ideal for a manufacturer of very small, complex, non-ferrous parts.

Q: What media can I use with the Standard Bowl?

A: Turbo Pins.

Q: What media do I use the CBW (wet) bowl with?

A: Porcelain balls or plastic medias.

Q: What media do I use the CBD bowl with?

A: Dri-Shine VII or Dri-Buff. The use of any other manufacturer’s media will void the warranty of the Magnetic Finisher.

Q: How long can I leave the Magnetic Finisher running?

A: The maximum is 60-minute cycles.

Q: If I magnetize the pins by accident, how do I remedy this?

A: You may either purchase new Turbo Pins or buy a demagnetizer locally.

Q: What happens if I try to finish ferrous metals?

A: Ferrous parts are magnetic and the machine will not function. Caution should be taken, as damage can be done to the machine if ferrous metals are attempted. If you have any questions, test with a magnet. Only non-magnetic materials can be used.
