Description
Version:
- Punch axis with carbide insert for applications with a high abrasive influence on the centring.
- Point angle 60°.
- Draw-off nut flattened at the side.
- High-precision bearing for high concentricity.
- Maintenance-free due to lifetime lubrication.
- Special seal prevents ingress of dirt and coolant.
Description:
Lathe centres are mainly used on lathes to support long and slim workpieces, since with these workpieces there would otherwise be a risk of the workpiece bending or moving around as a result of the forces generated.
The lathe centre is secured with a Morse taper. The workpiece is clamped in the chuck and a counterbore is added using a centre drill. After re-clamping, the lathe centre is then inserted.

Application:
Premium version. High concentricity due to high-end bearing. Designed specially for high speeds and high axial forces. Also suitable for grinding processes.
For machining thin workpieces at high speeds and in high quantities with automatic loading in series production.
