Description
Version:
- The pressure (clamping force) to be adjusted can be read off in kN directly on the manometer sight glass.
- Short sturdy design with active longitudinal axis. Tool is through hardened and finish ground.
- Precision bearing for high axial loads and high concentricity.
- With special seal against dirt and coolant ingress, maintenance-free due to lifetime lubrication.
- Length adjustment by means of spring package.
With extended centre, point angle 60° / 30°.
Application:
Whenever the clamping pressure 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 face drivers No. 327400 − 327403, 327455 – 327465 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.
