Description
Version:
- Sprung version for axial length compensation whilst machining.
- Fully hardened and ground. Maintenance-free due to lifetime lubrication.
- Special seal prevents ingress of dirt and coolant.
Plain shank for clamping in boring bar holders, collet chucks or hydraulic chucks; for mounting in the second turret.
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.
