SM1202 Series

High-Speed, Robotic Servo Spindle

The PushCorp SM1202 high-speed servo spindle is an ideal solution for robotic, material-removal applications such as:

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

The SM1202 can be ordered in a Random Orbital Sander or ER Collet Configuration. The sander has a Random Orbital Shaft that is designed to balance a 3", 5", or 6" backup pad. The part numbers for the various backup pad sizes and orbits can be seen in the table below. These sanders come standard with a dust collection shroud to extract dust from the parent material's surface.

Sander Configurations

Orbit Diameter 3" Disk 5" Disk 6" Disk
3/8" ASM03520 ASM03523 ASM03526
3/16" ASM03521 ASM03524 ASM03527
3/32" ASM03522 ASM03525 ASM03528

The “ER” Series features an ER20 collet, which 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 SM1202 has been developed as a lighter, more compact alternative to the SM1503. It features a powerful 2.0 hp [1.49 kW] servo motor that provides constant speed. This equipment is designed to mount in a parallel or perpendicular orientation on the AFD310 and AFD72 force compliance devices. As a result, it has never been easier to program beautiful and consistent surface finishes.
