RINGSPANN has been developing and manufacturing Precision Clamping Fixtures for workholding applications for over 75 years. Over the past decades we have realized thousands of applications and numerous technically sophisticated solutions. RINGSPANN specialized in clamping and centring on cylindrical internal and external surfaces. Typical components include automobile, gear and aircraft components. We have developed the RINGSPANN system on the basis of the RINGSPANN Clamping Disc, which encompasses • Complete Clamping Fixtures, ready-to-use and • Clamping Elements and components for customer...

High true running accuracyShort clamping lengths True running accuracy of < 0,01 mm is attainable. The RINGSPANN system permits short clamping lengths with high torque transmission. Short clamping fixture lengthExtended insertion depths Clamping Fixtures based on the RINGSPANN system ensure minimum spindle overhang and thus high spindle rigidity and precision. Short clamping fixture length The RINGSPANN system supports extended insertion depths with high torque transmission. Extended insertion depth No deformation The thinner-walled a workpiece is, the more sensitive to deformation it becomes....
