The RollerDrive CNC RC Series is a circular table designed to meet the requirements of machine tool manufacturers for greater speed and accuracy. The RC Series uses Sankyo's zero-backlash reducer, the RollerDrive to deliver output motion unaffected by external disturbances, unlike gearmotors or torque motors.
The high accuracy and rigidity afforded by the zero-backlash technology gives the RC Series its high rotary positioning accuracy 10 seconds maximum, and the ability to hold up to heavy cutting of hard steel.
