RC Series
The RC Series delivers exceptional positioning accuracy, high rigidity, and zero-backlash performance, making it the ideal rotary table solution for demanding CNC machining applications.
Over View
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.
Application
- Tool sharpening
- Machining of mirror cylindrical parts
- Machining of automotive ABS parts
Features
- Available in 5 Table Diameters
Available table diameters: 170, 200, 250, 315, and 400 mm - Large Hollow Center
Available with a large hollow bore in the table center. - High Accuracy
Rotary positioning accuracy 10 seconds maximum, repeatability 4 seconds maximum. - No Clamping
No clamping motion necessary because the mechanism is free of play.
