To use the RS drive in a CMM (coordinate measuring machine) application, you need to incorporate a linear scale with the drive. Amacoil provides a pre-integrated assembly which precisely monitors both linear position and travel direction. The unit provides smooth, vibration-free movement with no backlash. Resolution may be specified for either 0.0004 inches (0.01 mm) or 0.004 inches (0.1 mm). The RS-Linear Scale Assembly operates on a smooth shaft at rotational speeds of up to 8,000 rpm. Linear travel speed is up to 4 ft./sec. with axial thrust up to 202 lbs.
