At size 630 chuck body without convex outer contours

DURO-T - Key bar chucks with quick jaw change system with base jaws

APPLICATION:
Optimized for turning applications, which require extremely high clamping forces, maximum concentricity, as well as reliable long-term repeatability. In combination with a base plate, stationary use on milling machines, dividing units and machining centers.

TYPE:
Key bar chuck with quick jaw change system. 
Guaranteed maximum jaw precision as far as these are only used on the same chuck, and base and top jaws are kept screwed on for recurring work.

CUSTOMER BENEFITS:
- Maximum clamping force thanks to key bar system
- Concentricity and axial run-out tolerance twice as exact as required in DIN precision class 1
- Very high jaw change repeatability
- Balanced and jaws in chuck ground out for concentricity

TECHNICAL FEATURES:
- With jaw safeguard
- Chuck body completely surface-hardened
- Visual marking for quick jaw adjustment
- External shape incl. splash-water edge
- Fastening options for strongly stressed sliding surfaces
- Incl. safety key
- High corrosion protection

QUICK JAW CHANGE SYSTEM:
The RÖHM key bar chucks with quick jaw change system convince in two ways. On the one hand the jaws can be quickly and easily turned, changed or offset over the entire clamping range within a few seconds. On the other the key bar chucks convince with maximum clamping forces and maximum accurancy thanks to direct force transfer via the key bar system. Large, straight surfaces transmitting the force from the key bar to the jaw teeth guarantee long life and produce a very high clamping force combined with an accurancy which is twice high as required by DIN 6386. The high clamping force is achieved without much physical effort by manually turning the key.

ADVANTAGES AT A GLANCE:
- Maximum clamping forces thanks to direct force transfer via the key bar system
- Maximum concentricity and axial run-out tolerance
- High user-friendliness thanks to quick jaw change system
