The Gewefa family of face and taper tool holders today covers BT and DIN formats in SK30, 40 and 50 tapers. New length variants have been added to cover all formats, including collet chucks, shell mills, face mills, shrink clamp and hydraulic chucks, in standard or adaptor formats.
With face and taper, the crucial contact surfaces are precision ground to produce a rigid tool/spindle interface, while simultaneously optimising the clamping function. This design concept creates conditions for improved cutter life, and better maintained accuracy and cutting capability; features that impact positively on high speed and heavy-duty machining processes.
Gewefa has a long history as a manufacturer of face and taper tooling and, back as far as the mid-1970s, the company was manufacturing tool holders in this format for machines using Waldrich Coburg, Werner and Pfleiderer, and Ingersoll spindles. Subsequently, Gewefa developed its own range, which is completely interchangeable with other proprietary systems.
