Mirror grinding, you know?

What is mirror grinding

The surface roughness of the workpiece after grinding is Ra<0.01μm, and the light is like a mirror, which can be clearly imaged, so it is called mirror grinding. The flatness of the grinding plane is not more than 3μm/1000mm. Mirror grinding is required for surface processing of high-precision, high-value-added parts.

In view of these problems, the following points can be considered:

(1) When refining the grinding wheel, the diamond knife should be sharp, the grinding fluid should be sufficient, and the debris should be washed away in time, so as not to affect the surface of the grinding wheel.

(2) The grinding amount should be appropriate to prevent surface burns and other drawbacks from affecting the surface smoothness. Take care to leave an appropriate grinding allowance.

(3) The linear speed of the grinding wheel must be reduced to 15~18m/s.

(4) The grinding fluid is tightly filtered to prevent scratches.

(5) When the grinding wheel is finished with a grinding stone, the contact area between the grinding stone and the grinding wheel should not be too small, and the grinding stone used should not be too soft, otherwise it will not play the role of finishing the grinding wheel.
