1.Improve surface quality: Super finishing can reduce the surface roughness of the workpiece from Ra=0.2~0.4μm to Ra=0.012~0.050μm, significantly improving the surface quality.
2.Reduce defects: Eliminate defects and deteriorated layers in grinding, extending the service life of the workpiece.
3.Low noise and vibration: The noise and vibration of the processed workpiece are greatly reduced after assembly and operation, and the operation is smooth.
4.High processing efficiency: The processing time is short, only a few seconds to more than ten seconds, and the processing efficiency is dozens of times that of high-precision mirror grinding.
