5. How Can I Polish My Valves Without Damaging Them?

An important element of the valve polishing process is to ‘zero damage to the part.’

As much as possible, it is essential to have valve parts that are devoid of cracks and impingements.

To achieve this, some factors to consider include:

  • Suitability of Machinery
  • Choice of Media
  • Part Retention Time: In some cases, over-polishing may result in a bad finish. Hence, valve parts should not be polished for too long.
  • Polishing Compounds: Too little or too much polishing compound could cause damage to parts and result in an uneconomical process.

To handle the different valve materials here is what you must do:

Turbo Diesel Intake Valve: To get the best results while avoiding damage to this valve part, use a trough vibratory finisher with the appropriate polishing media.

Motorcycle Engine Exhaust Valve: If you can afford a CBFM, then you’re good to go but if not, a trough vibratory finishing machine will do a perfect job.

Automotive Valves: To avoid damaging this valve, use a centrifugal barrel finisher coupled with the appropriate polishing media.

You could also invest in the Zero Gap CF series for the best outcome.

Titanium Intake Valve: To achieve the best polishing results while avoiding damage to valve parts, invest in a CBFM coupled with the right type of media.

Engine Valve: In this case, use a centrifugal barrel finishing machine with the right polishing media to avoid damaging the valve part.

Stainless Steel Intake Valve: For the best outcome, use a trough vibratory finisher or a CBFM.

 

6. Should I Use a Centrifugal Barrel Finisher Or a Trough Vibratory Finisher For My Valve Polishing Operations?

Both types of machinery produce good results and are suitable for valve polishing operations.

However, a centrifugal barrel finishing machine provides amazing results when handling small parts.

Since valves are often very small, a CBFM can achieve thorough part polishing while leaving no stone unturned.

By design, the trough vibratory finishing machine is best suited to larger and more intricate parts, but they still do well with valves.

Hence, your equipment of choice will be dependent on functionality, and suitability.

 

7. How Does a Centrifugal Barrel Finisher Efficiently And Effectively Polish Valves?

This equipment is a high-energy and high-speed mass finishing machine, and it harnesses centrifugal force (G-force) during its operation.

The G-force utilized during operation induces a high-intensity contacting between the valve parts, media and compound agents (where applicable).

The contacting action results in a consistent, smooth and superior valve finish.

To ensure that valve parts are efficiently and effectively polished when using a CBFM, here are some practices to consider:

  • Do not overload the barrels.
  • Avoid too long valve processing cycles.
  • Where and when necessary, use polishing compound agents.
