Key bar chucks with quick jaw change system

for high precision in variable manufacturing with quick changing, turning and offsetting of the jaws.

The RÖHM key bar chucks with quick jaw change system are used successfully in areas where extremely high clamping forces, high concentricity and reliable long-term repeatability are required. 

RÖHM key bar chucks with quick jaw change system prevail in two ways. On the one hand, the jaws can be turned, changed or offset in just a few seconds thanks to the quick-change system. This reduces setup times. On the other hand, the key bar system prevails with very high clamping forces and accuracy that is twice that which is specified in DIN 6386. This is made possible by the large and straight force transmission surfaces between the key bar and jaw teeth.

  • quick jaw change
  • proven key bar chuck system with high efficiency
  • very good centrifugal force behavior or clamping force to speed ratio
  • highest repeatability

For

  • reduced set-up times
  • visual safety feedback when changing jaws

 

1: Precision and high force transmission through key bar system

2: Chuck body completely surface-hardened for maximum accuracy even under extreme loading

3: Jaws in the chuck milled for concentricity

4: Quick jaw change system with pressure bolts for turning, exchanging and moving the jaws in just a few seconds
