Abstract
PURPOSE: To obtain composite grain having excellent grinding efficiency, having long life to meet that emery cloth base becpmes strong.
CONSTITUTION: Fine grain 2 of grind stone of required grain size of #24W#1200 is put into hot water at 50°C and mixed by stirring, binder 3 made from urethane with hardening property due to humidity is charged quickly, being mixed up, and continuing above mixing until fine grain 2 of respective grind stone solidifies to nearly spherical shape as fine composite grain 1. Subsequently, the composite grain 1 is taken out, dehydrated, dried, siftted to grade required grain size, however it is desirable to grade to the grain size of four to seven times as large as fine grain 2 of grind stone. The spherical composite grain 1 is sticked on the cloth base.
