[0019] The technical solutions of the present invention will be further described in detail below through specific implementations.
[0020] A method for processing mirror rollers, using a grinder to grind the roller blank into finished mirror rollers with a roughness ≤ 0.006 microns, which specifically includes the following steps:
[0021] Step 1) Rough grinding: firstly use 80# grinding wheel to grind the roll blank to obtain a primary semi-finished roll with roughness ≤ 0.35 microns; then use 300 # grinding wheel to grind to obtain a secondary semi-finished roll with roughness ≤ 0.05 microns. The purpose of rough grinding is to remove the fatigue layer on the surface of the roll, blisters, gnawing and other defects, so as to facilitate roll pairing. The 80# grinding wheel and 300# grinding wheel are ceramic grinding wheels with a hardness of H. During the rough grinding process, the grinding wheel feed rate is 3 to 5 microns / min, the grinding wheel speed is 30 m / sec, the roll ...
