Design:
Collet attachments are always supplied with locking bolt.
Application:
The collet attachment is fastened using fastening kit 6375BA (observe torque specifications) on the base element 6375M. To secure the workpiece contour, the collet attachment must be clamped with the locking bolt. Then the workpiece contour is milled into the collet attachment with a minimum clamping depth of 2 mm. Then the locking bolt is removed, and the workpiece can be clamped. The collet attachment can be milled off to a height of H1, allowing new workpiece contours to be introduced. The maximum workpiece diameter is specified in the table with D1.
Note:
The collet attachment must always be clamped with the workpiece or locking bolt. To remove the vertical play between the collet attachment and base element, light pretensioning must be applied by actuating the clamping stud after the workpiece is inserted.
Advantage:
- Clamping of delicate and thin-walled workpieces
- Free-form clamping
- The workpiece is clamped without distortion due to the radially even clamping force imposed on it
- Multiple insertion of different workpiece contours possible
