Superfinishing machines are used in equipment that greatly improves roughness in a short period of time.
The superfinishing machine presses the stone to the rotating workpiece at a lower pressure to form a surface contact state, and at the same time, the stone vibrates in an axial direction at a higher frequency. Its main features:
1. Dramatically improved roughness in a short time (through superfinishing typically up to Ra0.025μm).
2. Since the workpiece is processed at low pressure, the surface structure of the workpiece does not change abnormally, and the surface metamorphic layer generated by the process (grinding or cutting) can be removed or largely removed.
3. Since the stone is in contact with the workpiece in a surface contact method, it is automatically profiling, so it can remove the surface ripples (prismatic circles) that are easy to appear in the grinding process, so as to improve the roundness.
