The premise of ensuring whether the polyurethane V-shaped roller can work better is fine grinding. Fine grinding of the roller can greatly improve the working quality of the roller. So, how should we do fine grinding?
1. Grind the grinding wheel of polyurethane V-shaped roller with 80 large pore grinding wheel;
2. When grinding the roller, the feed amount shall be controlled within 0.10mm and the cutting amount shall be controlled within 0.20mm;
3. Control the speed of the grinding wheel line at 30m / s, the rotating speed is 1900 rpm, and the reciprocating times are 2-3 times;
The air pressure shall not be less than 0.054 MPa without interruption.
Rough grinding can only ensure that the surface quality of polyurethane V-shaped roller meets the standard. In order to make it play a better effect in work, it also needs to be finely polished according to the above methods.
