1.  What is the Best Way of Polishing Crankshafts?

The most suitable way of polishing crankshafts is by using mass finishing equipment.

Mass finishing equipment involves the use of large-scale finishing machines, tumbling media, and also polishing compounds. Inovatec Machinery can supply you with all these equipment at your command.

There are three mass polishing machines that you can use for polishing your crankshafts.


The first machine is the trough vibratory polishing machine. It polishes effectively and rapidly. It is also ideal, especially if you have a tight budget, and you want to get things done the right way.



It works by vigorously shaking its rectangular polishing trough to create a tumbling effect.

The second machine is the centrifugal barrel polishing machine. It is incredibly robust and completes the polishing process faster than the trough vibratory polishing machine.



It is under the high-energy polishing machines’ category. However, it is quite costly when compared to the trough vibratory polishing machine. Its final finish is impeccable. It has a better finish than the vibratory polishing machine.

The last machine is the crankshaft horizontal polishing machine. It is primarily used to refine the surfaces of crankshafts at an industrial scale. It is also effective and efficient in the polishing process.



Bottom line:

Polishing crankshafts effectively is best done by using the recommended mass polishing machines.


2.   What is Polishing Media Ideal for Polishing Crankshafts?

Crankshafts are made from different materials. You can find aluminum crankshafts as well as titanium ones.

Depending on the material used to make your crankshaft, you can then choose the correct polishing media.

Two polishing media are widely used for crankshaft polishing – plastic and porcelain polishing media.

There are rare occasions when you can use ceramic polishing media – when there are burrs present on your crankshafts’ surfaces.



When you polish your crankshafts thoroughly using the correct polishing media, you make them stronger. Polishing gets rid of corrosion, contaminants, and surface blemishes.



3. How are Racing Crankshafts Best Polished?

Now, most racing crankshafts are known to be strong. They are usually made from aluminum or titanium.
