High Torque BT30 Tool Changer

The PushCorp STC0605-BT30 High Torque Servo Toolholder is an ideal solution for your heavy duty applications.  The STC0605-BT30 has a powerful 5 hp (3.8 kW) Servo Motor and integral Toolholding to give you the muscle, speed control, and holding torque to perform many operations.

The STC0605-BT30 Motor Shaft is configured to accept standard BT30 tapered toolholders.  Your standard CNC tooling along with custom tooling make it possible to utilize a wide range of abrasive disks, wheels, drill bits and cutting tools.  The Gripper mechanism maintains the tool position while, at the same time, providing a fast-acting release for rapid tool changes.

The STC0605 is designed to mount directly on the PushCorp AFD1000/70 Series Compliant Force Devices.  The STC0605 may also be mounted directly to the robot with no compliant device, providing a low cost machining center with a large work volume.
