Features of Precision Clamping Fixtures High true running accuracy Short clamping lengths True running accuracy of ≤ 0,01 mm is attainable. The RINGSPANN system permits short clamping lengths with high torque transmission. Short clamping lengths Short clamping fixture length Extended insertion depths Clamping Fixtures based on the RINGSPANN system ensure minimum spindle overhang and thus high spindle rigidity and precision. The RINGSPANN system supports extended insertion depths with high torque transmission. Extended insertion depth Short clamping fixture length 6-3 No deformation The thinner-walled...
