SM1503 High Speed Servo Spindle



High Speed Robotic Servo Spindle

The PushCorp SM1503 high speed servo spindle is an ideal solution for robotic material removal applications such as:

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

The SM1503 features a powerful 3.0 hp [2.2 kW] servo motor that provides constant speed. This equipment is designed to mount parallel or perpendicular on the AFD310 and AFD72 force compliance devices. As a result, it has never been easier to program beautiful and consistent surface finishes.

The SM1503 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 SM1503 has been developed as a lower priced alternative to the STC1503-BT30. The SM1503 uses the same 15,000 rpm high speed motor from the STC1503, but without the automatic collet release. Instead, a manual "ER" Series collet is used to clamp the tool shaft. This means that operator intervention is required when the media needs to be replaced. For applications where the abrasive media or the tools have a long life the manual collet is the ideal solution.

The Kollmorgen S724 amplifier powers the servo spindle, provides analog speed control, and digital I/O. This can be ordered on it’s own or integrated into a UL certified control panel.
