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.

Advantage:
Push-off nut can be removed forwards thus eliminating any obstruction to the machining process.
Application:
Machining small and very small parts such as thread machining with optimum access to the flat face.
Supplied with:
Including draw-off nut.
