Precision clamping chucks

Watchmaker lever scroll chuck

We have discontinued the production of our watchmaker chucks since March 2017.

Of course, our stainless chucks are still available. This product category will continue to be expanded.

The chucks are especially suited for light and precise work with low clamping forces in individual construction. Tensioning the work pieces is performed by turning the geared scroll without a key. The precision ring chuck RF75 and the level chuck StF60 are suited to light work on circular and disc-shaped parts. The soft clamping jaw levels can be subsequently processed as required. This allows for absolute maximum concentricity. Replacement jaws can be supplied prefabricated.
 
All types can be delivered with mounting shank for watchmaker lathes:

  • Ø 8 mm thread 6.85 x 40 Gg.
    e.g. manufacturer Boley & Leinen
  • Ø 8 mm thread 7 x 40 Gg.

Special fixtures can also be manufactured according to drawings on request.
Special chucks can also be supplied in stainless steel.
