Description
Version:
- With extended centre and draw-off nut, specially for CNC machines.
- Complete tool hardened and ground.
- Special roller bearings for high loads and speeds.
- Live centre through hardened, can be reground many times.
- Maintenance-free due to lifetime lubrication.
- Special seal prevents ingress of dirt and coolant.
Extremely slim casing, flattened on one side, for optimum access; very high concentricity due to high-end bearing; also suitable for grinding applications.
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 high loads and speeds, specially for NC machines.
Flexible application thanks to exchangeable inserts. For general use on turrets and counter-spindles on CNC machines.
