   RBAK NC power vices


For the universal application on milling
machines and machining centers.
Horizontal, vertical or side mounting with
height adjustment ±0.02.
Without angle drive, high reliability, long
working life and high precision

Clamping system mechanical-hydraulic with
power transmitter, manually operated.



Technical features:
•  steel body with stationary jaw, uniformly forged into the die
•  automatic reclamping in the hydraulic unit via the installed belleville spring
•  all wear parts, primarily the jaw guides, are hardened and ground
•  robust guide surface of the movable jaw
•  with normal jaws and hand crank

Customer advantage:
•  robust and maintenance-free spindle
•  the short design of the movable jaw (made of steel) allows a reduced overall
   length even by max. clamping width
•  further stepped or special top jaws can be fixed on the top of the stationary
   and movable jaws
•  locking pin is protected against dirt and chips
•  large clamping range
