Variety and Characteristic of Super Finishing Stone

What is
Super Finishing Stone

Grindstone for polishing final stage of Metal product’ s surface.
By making the metal surface roughness fine, the surface will be less friction resistance, and less affected layer.
Suitable for every kind of Bearing’ s truck surface and for Needle Bearing’ s and Rollar

Features and Advantages
of the Super Finishing Stone

1. The grit is chipped and comes off moderately when multidirectional oscillation is applied. As a result,the stone stays sharp longer and superior, constant performance is ensured.
2. Since the grindstone requires less pressure and slower speed than conventional tools,minimal heat is generated during the polishing process. Therefore, metal surface layer will not change.
3. The super finishing stones are user-friendly tools. Using stones with dedicated machine is a cost-effective way to grind a workpiece efficiently and accurately to very fine surfaces and contours.

Our engineers test our products using a variety of testing machines to suit your production needs.
