Rotary tables for machining centers

RCD series

Overview

The RollerDrive CNC RCD Series is a rotary table designed to meet the requirements of machine tool manufacturers for greater speed and accuracy. The RCD 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 RCD Series its high rotary positioning accuracy 10 seconds maximum, and the ability to hold up to heavy cutting of hard steel.

Features

Permanent accuracy
By adopting our roller drive mechanism, there is no deterioration in the internal parts of the RCD Rotary Table and its accuracy does not deteriorate after long-term use. It has excellent durability. No routine calibration or adjustment work is required.
Excellent performance characteristics due to the zero-backlash design
With our roller drive mechanism, it is possible for repeated output operations to be equally precise, without being disturbed by external forces. Because it achieves high-precision positioning with a rotational accuracy of 10 seconds or better, it can also be used for heavy cutting on hard steel.
No clamp operation
Since the roller drive CNC has zero play due to its design, it does not require any clamping operations. With this design, clamping and unclamping time is effectively eliminated and no other energy source is need, unlike conventional hydraulic systems.
