PushCorp STC0440-BT40 High Power Spindle Review: Specs, Price and Applications
The PushCorp STC0440-BT40 is a high-power robotic spindle with a 40 hp (30 kW) servo motor, 50.9 lb-ft (69 N·m) continuous stall torque and 0 to 4,000 rpm reversible speed. It weighs 146 lb (66.2 kg) and requires liquid cooling.
It uses BT40 toolholders with fail-safe pneumatic quick change, quad front and duplex rear bearings for high loads and rigid mounting, and mounts on AFD1240 and AFD92 devices. A Kollmorgen AKD amplifier provides speed control.
Quick Verdict
Serious machining power on a robot, for drilling, routing and gate removal in heavy materials.

Design and Operating Principle
PushCorp servo spindles are liquid- or air-cooled, permanent magnet, brushless, closed-loop motors that deliver constant torque across the speed range. Fail-safe pneumatic quick-change toolholders let the robot swap media or cutters automatically, and the spindles mount to PushCorp compliance devices or directly to the robot for rigid work.
Quad front bearings handle radial and axial cutting forces from milling and drilling.
Integration and Selection
Use large robots, liquid cooling and the AKD amplifier; mount on AFD1240 or AFD92 or rigidly.
Supply 90-100 psi clamping air.
