Description
Version:
- Extremely slim body and high concentricity.
- Precision needle and thrust bearings result in a maximum variation of 0.003 mm and a very small body ⌀.
- Taper and chamfered parts are made of hardened bearing steel (61 − 63 Rockwell).
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 turning and grinding where a small head ⌀ and high accuracy are required.
