Steel wheel as a "universal grinding tool " curing machine processing of coated abrasives is not only wide range of grinding efficiency, but also to achieve high precision and low surface roughness, so demanding on the joints. Coated Abrasives adhesive joints should have:

1) strong enough degree of mechanical strength must be greater than or equal to the abrasive belt is the mechanical strength;

2) curing the elongation requirements of coated abrasives and consistency;

3) The joint thickness and the thickness of coated grinding the same or identical to the precision required for high precision surface grinding is especially important;

4) steel wheels flexibility consistent with the coated abrasives, so as to avoid brittle fracture in the bend when used.
