Operating pressure for opening: min. 40 bar - max. 60 bar.
Hydraulic pressure of 40 - 60 bar is required for opening the collet. In the de-pressurised state, the collet attachment is securely tensioned by the integrated spring package.
The main body is is made of burnished steel. The collet attachment, which is supplied as standard, has a diameter of 99 mm and is made of anodised, high-strength aluminium. The hydraulic clamping unit is protected against dirt and cooling water.
Circumferential clamping edge for fastening to the machine table.
The holder for the AMF K20 Zero Point system, as well as grooves for positioning on AMF Zero Point clamping modules with indexing, are applied to the underside.
For automated operation, a hydraulic connection, sealed in the delivered condition, is present on the underside.
The lateral hydraulic connection is suitable for the mounting of a quick-release coupling with connection thread G1/4.
For clamping complex workpiece contours for 5-sided machining in the machine tool. The counterplate of the workpiece is milled into the collet attachment with a minimum clamping depth of 2 mm. Since the clamping force is evenly applied to the component in a radial direction, the counterplate is clamped warp-free.
Thanks to the simple collet attachment replacement, various workpieces can be quickly and securely clamped for 5-sided machining.
The collet attachment can be milled off up to a height of H1, thus allowing new workpiece contours to be introduced.
With a mounted collet attachment, the clamping unit must not be closed without a workpiece.
* The max. clamping force of 13 kN is exerted axially to the collet and does not refer to the clamping force exerted on the component. This varies according to the machining height.
