5. after the rough grinding polishing disk 75 finishes polishing, reversing the feeding motor 771 on the rough grinding assembly 7 to enable the rough grinding polishing disk 75 to be separated from the surface of the roller;

thirdly, fine grinding roller:

1. the feed motor 771 of the refining assembly 8 is started, the feed motor 771 drives the refining polishing disc 81 to move towards the roller member, and when the refining polishing disc 81 is attached to the roller member, the refining polishing disc 81 polishes the surface of the roller member. In the polishing process, the current sensor 91 outputs the current of the driving motor III 72 to the PLC control system 9, and when the current is kept at the set current preset value, the feeding motor 771 does not convey the rough grinding assembly 7 any more, so that a good polishing effect is achieved;

2. in the process that the fine grinding polishing disc 81 rubs the roller, the control motor 61 drives the mounting seat 6 to move along the length direction of the roller, and the photoelectric sensing assembly is used for sensing the positions of two ends of the roller, so that the fine grinding polishing disc 81 performs reciprocating polishing motion on the roller;

3. after finishing the polishing of the fine grinding polishing disc 81, the feed motor 771 on the fine grinding assembly 8 is reversed, so that the fine grinding polishing disc 81 is separated from the surface of the roller, thereby finishing the fine grinding processing of the roller and enabling the surface of the roller to present a mirror surface effect.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
