Precision Clamping Fixtures

RINGSPANN has been developing and manufacturing Precision Clamping Fixtures for work holding applications for over 75 years. They specialized in clamping and centring on cylindrical internal and external surfaces. Typical components include automobile, gear and aircraft components.

RINGSPANN have developed the system on the basis of the RINGSPANN Clamping Disc which encompasses Complete Clamping Fixtures, ready to use and Clamping Elements and Components for customer assembled Clamping Fixtures. The system offers the right solution for each clamping application and guarantees maximum clamping precision without the need for complicated alignment. This enables customers to achieve difficult objectives, such as clamping in short lengths or clamping thin walled components that are susceptible to deformation.
