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:
For machining thin workpieces at high speeds and in high quantities with automatic loading in series production.
Designed for high axial forces during heavy-duty machining thanks to special bearing arrangement.
