Revolving lathe centre with pressure indicator and extended point 4

• The adjusting pressure (clamping force) is directly readable on the manometer sight glass in daN.
• The live centre, which is supported by a disc-spring pack, has a long spring travel.
• Short sturdy design with active longitudinal axis. Live centre through hardened and finish ground.
• Maximum accuracy due to precision roller bearings.
• With special seal against dirt and coolant ingress, maintenance-free due to lifetime lubrication.

With extended centre, point angle 60° / 30°.

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.

Whenever the clamping force has to be kept within certain limits,either to prevent deformation of the component or to ensure secure clamping with sufficient pressure.

• As a tailstock centre in conjunction with hydro-mechanical face drivers No. 327451 − 327541 because the drive teeth have to dig into the component.
• For components that expand significantly due to high machining heat.
• For clamping long slender components to prevent lateral displacement.
• For clamping heavy components where a controlled clamping force is required.
