Series 81 live centers with sprung shaft

Request sending information.

This is a spring operated live center, it is designed to be applied on counter spindles and on live tooling turrets.
Since these electric axes are used only for positioning and not for a continuous thrust pressure control on the workpiece, the live center series 81 holds the piece to be machined underthrust. Changing the shaft axial positioning it is possible to obtain increasing axial loads.
The light version is available with integral shaft, cylindrical connections and hard material; the reinforced version has the shaft with interchangeable centers applied, cylindrical connections, MT and VDI.

Features:

  • 3÷4 bearings, depending on the model (reinforced or light).
  • Shaft with stroke predetermined by springs for cases in which a live center on a machine axis is needed. The springing system therefore compensates for any differences in part length.
