1. Max clamping diameter : O.D. 130mm
2. This chuck clamps workpiece by a combination of centering mechanism by elastic deformation of U-shaped springs and face clamping mechanism by swinging vertical movement.
3. It centers workpiece gently based on outside diameter by top jaw and holds a face of workpiece firmly by face clamper, minimizing clamping deformation even if it’s thin-walled workpiece.
4. Thanks to its built-in air cylinder, fine adjustment of clamping force is possible.
5. Face clamp mechanisms are independent each other, enabling it to clamp workpiece evenly even if workpiece is not finished within a good tolerance.
6. Face clamp swings and then moves down to hold workpiece, and it moves up and then swings to unclamp, which allows clamping in a narrow space.

Main functions

1. Air circuit for seating air sensor.
2. Through coolant circuit.
3. Air circuit for increasing clamping force.
4. You can increase O.D. clamping force by pulling U-shaped spring by built-in air cylinder.
5. Combination of base jaw and top jaw (exchanging repeatability : 5µm)
6. For both horizontal and vertical machine
7. For turning, machining and grinding
