grinding wheel roller pores choice

Suitable for large pores rubber roller grinding wheel Grinding coarse particle size generally use 45 # -60 #, 80 # grinding wheel selection; but wide face wheel (A803S grinder) rubber roller grinding wheel size can only use 45 # -60 #, this is because the cbn grinding wheels  polishing process A803S grinding roller surface of the polishing wheel surface is always in contact with, the heat dissipation is not easy polishing, use a large wheel size, enabling the heat, but is conducive to reduction roller surface roughness.
Grinding wheel and abrasive particle size distribution of the state for the quality of sharpening roller is very important, small size, tight grain distribution, the  diamond grinding wheel wheel in small pores, tempered heat generated when loss is not easy, the light effect roller surface roughness degrees, severe damage to the surface of the roller organizational structure, so that the physical and mechanical properties of roller down.
In the polishing process, the polishing dust is often adhered to the rubber surface and the  industrial saw blades abrasive surface clogging the pores of the wheel, there is no space between the grains, loss of cutting ability. With high hardness, well organized, fine grain size of large pores wheel most prone to clogging, which is often trimmed wheel (commonly known as copy wheel) causes. Experimental comparison shows that the large pores 45 # 60 # wheel than twice the length of use of time;'s four times longer than the 80 #; than 40 times the length of 120 #. Ie the same amount of grinding roller; 45 # of dressing a grinding wheel 20 days; 60 # of 10 days finishing time; 80 # of five days trimming once; 120 # of one day to the secondary dressing. So grinding rollers for general use 80 #'s more applicable in wheel dressing cycle, both to meet the accuracy requirements of sharpening roller. Roller can ensure a good surface state.
