CNC Rotary Tables


RollerDrive CNC - The Answer for a CNC Rotary Axis

Pure Motion By Zero-Backlash Technology

CNC Rotary TablesThe RollerDrive CNC, a CNC rotary table, is designed to fulfill the demands of the latest machine tools for increased speed and precision.  Inside, Sankyo rotary tables use a RollerDrive mechanism, our zero-backlash reducer technology. This mechanism transmits motion without distortions while staying robust against external forces unlike existing gears and torque motors.  The high precision and rigidity achieved by the zero-backlash technology gives the RollerDrive CNC a rotational accuracy of less than ±10 arc seconds and repeatability of less than ±4 arc seconds and remains robust while doing heavy cutting work on hard materials.

No Clamp Operation
The Rollerdrive CNC rotary table does not require a clamp to hold table position due to its mechanically rigid zero-backlash structure.  This eliminates clamp and unclamp time and requires no energy like conventional hydraulic/air systems.  Combined, the distortion-free performance and no-clamp design delivers ultra-fast positioning that leads to higher productivity.  For instance, a typical 90-degree rotation can be done within 0.3 seconds. This cycle time is impossible with conventional worm gear tables that require a clamp to hold position during machining operations.
 
Perpetual Precision
The unique mechanism of the RollerDrive makes the RollerDrive CNC capable of withstanding years of operation without internal part wear or loss of precision.  Regular calibration or readjustment work is unnecessary for the RollerDrive CNC.
