The Ultimate CNC Rotary Table Zero-backlash Technology Delivers Unsurpassed "Motion" The RollerDrive CNC is a rotary table designed to meet the requirements of machine tool manufacturers for greater speed and accuracy. The RollerDrive- Sankyo's zero-backlash reducer—delivers accurate output motion that stands up to external disturbances, unlike gearmotors or torque motors. It offers excellent rotary positioning accuracy of 10 seconds or less, and can hold up to heavy cutting forces on hard steel. The heavy-duty RollerDrive CNC has no internal part wear and no loss of accuracy over long-term...

No Maintenance and Excellent Price Performance Consistent long-term accuracy without maintenance. Positioning Accuracy Aging Test Requires maintenance over time Operating cycles Consistent long-term accuracy without maintenance. The RollerDrive graph is based on internal testing. (Center distance of test unit: 170) Worm gear models Accuracy declines over time. Requires maintenance to achieve initial Accuracy is consistent with no maintenance even after 5 million operation cycles. Extended Accuracy Compared against a worm gear for over 5 million indexes. ■ lltElfcff Test conditions Table...

Technical information Backlash, lost motion, hysteresis loss —SSW&tT.xUS/XSSil General hysteresis graph S^)!c#fflt"5 \-M Torque acting on output [N-m] For a general reducer, the hysteresis graph can be obtained by applying torque to the output shaft, and plotting the generated torsion angle. Backlash, lost motion and hysteresis loss can each be defined from the hysteresis graph, as indicated above. Lost motion and hysteresis loss depend on the material characteristics, and occur in all types of structures. Backlash, on the other hand, occurs only when there are gaps or looseness in the...

/i^tW^H Precautions Sankyo's CNC Circular Table comes standard equipped with an air purge outlet. (Use it to blow out condensation and coolant to prolong the life of electrical parts and prevent rust in the motor housing.) Supply clean air for the air purge by referring to the drawing shown below. (Do NOT block the exhaust outlet.) Sankyo's CNC Circular Table uses an oil bath to protect the internal mechanisms and maintain reliability. Refill and perform oil changes regularly using the oil listed in the instruction manual. Grinding Machine Applications When used in grinding machines, the...
