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.

Application:

Flexible application thanks to exchangeable inserts. For general use on turrets and counter-spindles on CNC machines.

Optional extras:

Exchangeable inserts No. 320625.

Note:

Changing the inserts in the key surfaces by counter-rotation.
