Depending on the number of pieces and the geometric size of the workpieces to be machined, superfinishing attachments are used on conventional grinding or lathes.

Superfinishing Attachments

Tape and stone finishing for your carrier machine

Supfina attachments are available with tape, stone, or as a hybrid version. We will be happy to advise you on which version is the perfect one for your application.

Thanks to the quick and uncomplicated integration to existing lathes and the process support provided by Supfina, you can get started immediately. In this way, you instantly increase your competitiveness and meet all customer requirements.

The advantages of Supfina attachments

  • Tape finishing devices
    can be converted from tape to stone finish, with dry machining possible
  • Pneumatic finishing devices
    robust and inexpensive all-round devices, with a small footprint
  • Mechanical finishing devices
    impressively smooth running, stable parameters under load change
  • Ball finishing devices
    Surface finishing on flat and spherical surfaces
