The contact roller (110 x 100 mm) is compatible with the Bohle belt grinder Master Belt Series 780.x. The grinding or polishing belt is centred on the contact roller.
Grinding, arrissing and polishing of inner radii is no different from grinding, arrissing and polishing of straight edges. However, to ensure access to smaller inner radii as well, a different contact roller should be selected:
Option contact rolls for inner radii
BO 80.40 Contact roller Ø 200, grinding radius approx.60 mm, width 50 mm, for grinding belt width 60 mm
BO 80.41 Contact roller Ø 200, grinding radius approx.100 mm, width 50 mm for grinding belt width 60 mm
