Rotary tables for machining centers

RT series

Overview

In terms of performance, Sankyo’s roller gear does for rotary motions what the ball screw does for linear motions. The roller gear cam mechanism consists of a roller gear and globoidal cam. Similar to the preloading structure of a ball screw, the roller gear has no backlash, and transfers power by rolling contact for strong rigidity and excellent efficiency. And no clamping is necessary.

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.

No Maintenance and Excellent Price Performance

Since the torque is transmitted by rolling contact, the internal mechanism does not wear and the positioning table always maintains its initial level of accuracy, even after long-term use.
