EEA Blind-hole type Roller burnishing tools
Characteristic
Model : EEA
Burnishing is a cold working process which uses to polish the surface by the pressure of the balls during the spinning.Available to solenoid valve, pneumatic or oil cylinder, bearing motor, bushing or any kind of hole-tumbling.
The surface roughness could be up to Ra 0.4-0.1
Able to burnish the surface without damaging and gaining 30% anti-corrosion.
