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.
Extended point allows unobstructed access for the turning tool on the end face of the component. Particularly suitable for copy turning.

Note:

Draw-off nut for NC machines to remove tip from tailstock sleeve.
