Setrite^TM Adjustment Diameters 160 to 790mm The original high speed quick change chuck has a jaw change of less than 40 seconds. The Setrite™ feature is fitted as standard with repetitive gripping accuracy of 0.025mm TIR. It is counterbalanced against the loss of grip caused by centrifugal force operating on the top jaw. Designed for small batch production on CNC lathes, it has direct or indirect mount to A and DIN type spindles. Base jaws (60 or 90 degree serrations or acme) take collet pads, serrated, smooth or soft. Big bore and long stroke versions are also available.
