Material of Different Valve Polishing

If it’s an engine, there are valves. No engine can work without valves. Valves control the flow of intake and exhaust gases. So, the precision of the polishing is crucial when it comes to engine valves.

In order to effectively polish engine valves, you can use a centrifugal barrel finisher for faster results. Put the valves in the barrel and load it up with the right media.

Diesel engines are different from gasoline or petrol engines. The structure of the engine is different and the components are different as well. So, when it comes to turbo diesel intake valve polishing, you should be careful about what media or equipment you are using.

A trough vibratory finishing machine could be your best friend in this case. The tub is long enough to hold a lot of parts at once. It’s a cost-effective and efficient method.

Titanium is the pinnacle of performance parts. Automotive enthusiasts are very eager to install titanium parts on their cars or motorcycles anytime they get the chance. Titanium intake valves are the same. They are light, they are strong, and they provide astounding performance.

To polish titanium intake valves, it’s necessary that you invest in a centrifugal barrel finishing machine. It might seem costly in the beginning, but remember that the titanium intake valves are expensive as well. You should not take the risk.

Stainless steel intake valve polishing is the same as polishing other materials. We use either a centrifugal barrel finishing machine or a vibratory finishing machine to get the mirror finishing.

Motorcycle engines have valves, similar to any other vehicle. But motorcycle valves are smaller in size and take significantly higher abuse, thanks to the high revving engines. So, it’s very important that motorcycle exhaust valves are well polished before they are installed.

For motorcycle exhaust valves polishing, you can go with the centrifugal barrel finisher if you have the budget. If not, a trough vibratory finisher would do the job just fine.

Automotive valves are the valves that go inside the vehicle engines. Automotive valves can be of different types, sizes, and shapes. Cast iron, cast aluminum, forged steel, forged aluminum, sand casting aluminum, etc. are the commonly used metal to make automotive pistons.

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.

Now, you know, how to clean cylinder head valves and how to remove carbon deposits from valves by using Inovatec valve polisher machines.

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

You can use both these machines as an exhaust valve cleaner machine.

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.

Now, you know, how to clean cylinder head covers and how to clean cylinder head ports using Inovatec machines.
