STC1503 BT30

High Speed Robotic Servo Spindle

The PushCorp STC1515 high speed servo spindle is an ideal solution for robotic material removal applications such as:

  • Robotic Grinding
  • Robotic Sanding
  • Robotic Polishing
  • Robotic Deburring
  • Robotic Routing

The STC1515 features a powerful 15 hp [11.2 kW] servo motor that provides constant speed. This equipment is designed to mount parallel or perpendicular on the AFD620AFD82AFD1240, and AFD92 force compliance devices. As a result, it has never been easier to program beautiful and consistent surface finishes.

The STC1515 may also be mounted directly to the robot with no force compliance device. This opens the door for rigid applications such as routing and deflashing.

The motor shaft is configured to accept standard BT30 tapered toolholders. Customers can choose to use standard off the shelf CNC tooling as well as custom PushCorp toolholders. Together, these components allow for a wide range of abrasive disks, wheels, drill bits and cutting tools.
