8-2. Supply of pneumatic and hydraulic pressure for clamp
The clamper to clamp the table is incorporated in the NC rotary table and two air and hydraulic clamp
specifications are provided for operation. However, in the air pressure clamp specifications, the air
hydraulic booster is incorporated in the table. Since the NC rotary table is delivered in accordance with
the customer
’s specifications, supply a pressure source according the specifications.
8-2-1. Pneumatic clamp specifications
1) Supply clean air (moisture, oil content, powder dust eliminated) passing through the air combination
(Air filter, mist separator, regulator) + drain catcher.
2) Connect the pipe exclusive for air pressure durable to max. operating pressure over 0.6 MPa to the
air pressure supply port. The air pressure supply port is provided on the motor case. See the
external view attached for details. (Connection port is Rc1/4).
3) Use this unit in the air pressure range of 0.45 to 0.6 MPa.
4) If the air remains in the table clamp device, the specified clamp torque cannot be attained. Thus,
perform the air bleeding work .[Refer to section 8-3]
8-2-2. Hydraulic clamp specifications
1) Connect the pipe exclusive for hydraulic pressure durable to max. Operating pressure over 3.7 MPa
to the hydraulic pressure supply port. (Connection port is Rc3/8)
2) Use this unit in the hydraulic pressure range of 3.5 to 3.7 MPa.
3) If the air remains in the table clamp device, the specified clamp torque cannot be attained. Thus,
perform the air bleeding work .[Refer to section 8-3]
Port Rc 1/4 is provided. In the hydraulic clamp spec., use connection port
of Rc 3/8 for different diameter.
Using the hose equivalent to 3/8 is recommended.
