CUMI
Reduced dressing frequency Burn free component Higher productivity and
efficiency High form retention Superior surface finish
Higher cutting speed and strength, increases efficiency
Longer machine life due to reduced grinding forces
Less chatter marks Eco friendly - reusable FRC core
helps with keeping the manufacturing process green
Reduced machining time: Heat resistant CBN grains allow fast rotation and fast feed
Reduced costs: High hardness of the wheel gives it longer life
Prevents thermal overloads on the work piece despite extremely high material removal rates
Reduced dressing frequency
