Solid Rotary Hydraulic Cylinder(CHECK VALVE)

L-RA:Air Connection
1. A central output airway is used to actuate the customized jigs or for gap detection.
2. Hydraulic rotary cylinder is used to actuate the power chuck clamping action.
3. With built-in “check valve”, work pieces can be effectively prevented from flying out during abrupt failure of pressure.

L-RC:Coolant Connection

1. A central output coolant way is used to connect to the front jigs to inject coolant for cleaning chips or performing other tasks.
2. Hydraulic rotary cylinder is used to actuate the power chuck clamping action.
3. With built-in “check valve”, work pieces can be effectively prevented from flying out during abrupt failure of pressure.
