Clamping elements 682

Clamping mandrel XPA

Design: Made of construction steel, with hardened and coated clamping screw. The mounting flange diameter is concentric to the clamping diameter so that high repeat accuracy of the parts is achieved. Application: Almost every workpiece (e.g. rotary part, milled part, drilled parts etc.) has at least one hole, and this is what is used by the XPA clamping mandrel for clamping. Thus clamping takes place from inside enabling machining of the 2nd side without problem. The compact dimensions allow multi-face machining without disturbing edges for the tool. The clamping mandrel can be machined and can be adapted to the respective diameters by turing and milling. Can be automated using hydraulic and pneumatic equipment. Scope of delivery: Clamping mandrel with 3 fastening screws. Note: Allen key is found from Ç 5/123.
