The PushCorp SBS81 Servo Belt Stand combines compliant force control with a high-torque servo motor.  This precise force and speed control allows you to achieve unprecedented levels of quality and consistency.
The SBS81 is designed to enable maximum flexibility for any part-in-hand grinding, sanding, buffing or polishing application.  Linear travel compliance and excellent access allow a robot to easily manipulate parts over the  belt media.
The contact wheels of the SBS81 are belt driven by a high-torque servo motor.  This drive system has a 2:1 reduction that provides plenty of power at the contact wheels.   The belt media is tracked remotely keeping personnel out of the workcell during operation.  Easily removable contact wheels allow widths of 1", 2", 3", and 4", plus a wide range of different rubber hardness.  Changing the belt media is a snap with pneumatic tension and conveniently positioned manual valves.
Here are just a few operations the SBS80 can accomplish faster, more accurately, and with greater control than ever before:

Grinding (casting gates, weld beads)

	Deburring (parting lines, chamfer)
	Polishing (glass, wood, metal)
