RÖHM DURO-A 315 power-operated chuck with 90-degree pointed teeth, ZA 300 cylindrical shank

The Duro-A is a three-jaw through-type chuck that can be actuated automatically, i.e. hydraulically by a CNC machine. It is primarily used for turning operations on cylindrical and disc-shaped workpieces. Stable clamping through axial tightening; the workpiece is pulled down against the rigid stop automatically by the operation of the clamping mandrel. Vibration damping due to the high proportion of vulcanised material in the clamping sleeves; prepared for pneumatic system control; compatible with Type 269-90 intermediate flanges. Technical features: high flatness and concentricity accuracy; high repeatability; Clamping force remains constant over 500,000 cycles; wedge-hook principle; fixed base jaw, top jaws via slotted nuts; threaded ring pre-fitted. Applications: automatically clamping machining centres. Machining of bars, tubes, flanges and discs by turning. Advantages: High clamping forces (up to 250 kN in the 400 series version); High speeds (up to 8,000 rpm in the 165 series version); Reduced interference contour; Large through-bore Further information: The Duro-A diameter 315 is a three-jaw chuck with a through-bore diameter of 98.5, a cylindrical shank ZA 300 and 90-degree pointed teeth, which can be actuated automatically, i.e. hydraulically by a CNC machine. It is primarily used for turning operations on cylindrical and disc-shaped workpieces.
