HIGH SPEED AIR CHUCK
High speed precision air chucks are designed to spin at up to 4000-6000 rpm. The high speed air chuck has a large back body with smaller front, allowing easier access to the workpiece while maintaining very large gripping force at high rotating speed.
Repeatability is 0.002mm or 0.00008".
Chuck size ranges from 80mm to 105mm or 3 in up to 4 inch (front side). Larger chucks are available upon request.
