Description
Version:
- Centering taper with truncated cone.
- Particularly sturdy design with oversize bearings.
- The bearings have a special lubricant and require no maintenance.
- The centering taper and tapered arbor are made of high quality material, through hardened and finish ground.
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 hollow parts, tubes etc. Particularly suitable for heavy machining where at the same time high accuracy is required.
