Gewefa face and taper toolholders – extensive range for high precision, heavy duty machining

The Gewefa family of face and taper toolholders is one of the most extensive available and now covers BT and DIN formats in SK30, 40 and 50 tapers to offer comprehensive capability for heavy duty and very high speed machining applications.

Gewefa face and taper toolholders are available as collet chucks, shell mills, face mills, shrink clamp, hydraulic chucks and in extended length and adaptor formats.

Although a specialist technique, machining using face and taper toolholding technology comes into its own when metal cutting in applications where side thrust is a possibility – typically heavy duty milling operations.

Here, side deflection could be detrimental to precision and consistency of cut. In such circumstances the rigidity of the spindle/toolholder connection can impact positively on longer insert life.

Toolholders of this format also offer sustained precision and resistance to deflection when machining using extended length or overhanging tools and in processes such as deep pocketing or deep hole boring.

A Gewefa toolholder fitted in a suitable spindle offers two mating surfaces – on both the gauge line (taper) surface and the horizontal flange face surface.

This connection differs from conventional taper tools in that both the contact surfaces between the toolholder and the spindle are precision ground to the exact standard.  When the drawbar is activated on the machine the toolholder is secured in the spindle to contact on all surfaces creating a rigid contact environment which is resistant to vibration and deflection.
