Project Description

Guide Collets

• WALTER DÜNNER SA produce Carbide Collets.

  For the holding of complex pieces in the counter spindle, WALTER DÜNNER SA patented the well-known “large opening collets”. These collets allow over gripping on a larger diameter than the clamping diameter. Medical applications, such as screws or dental implants, use more and more Dünner’s “large opening collets.”

  The LONGSTAR collet was developed to increase the clamping force. They give excellent results as headstock collet by assuring regularity of the pieces produced even by heavy turning of material. This collet replaces easily the Hainbuch system and it is more economical as it requires no special adaptation. It can also be used as counter spindle collet if a minimum clamping length of 20mm is respected into the bore.

  The LONGSTAR collet is also very attractive because of its large clamping range of 0.5mm.
