9 GRINDING APPLICATION
9-11
C. Binding agent
Binding agent includes Vitrified(V), Silicate(S), Rubber(R), Resinous(B),
Shellac(E) and metal (M). Vitrified is the hardest and strong binding agent, only
very few amount would obtain would obtain high hole rate to required bindng
degree with very few clogs on grinding wheel. The bound wheel is very sharp and
has high strength. Hence, it takes the most part in grinding work. Vitrifed grinding
wheel is used in most centerless grinding machine. When finishing or accuracy
isrequried, shellae or rubber binding grinding wheel are applied. Regulating wheels
almost are ubbersbinding grinding.
D. Binding degree
Binding degree represents strength of binding agent. The following is its
classification:

Grinding wheel has the degrees of K, L, M while regulating wheel has degreesof
Q. In all times, hard binding degree is applied to soft workpiece, however, and
soft binding is applied to hard workpieces. Besides, brass and copper based soft
workpiece adopt hard binding degree to prevent hole from being clogged.
