Zero-backlash Technology Delivers Unsurpassed MotionThe 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 use, thus eliminating the need for regular calibration or adjustments.

Theory of Operation of the RollerDriveThe RollerDrive uses the roller gear mechanism, one of the finest motion control mechanisms available. The unit is constructed from an input shaft (the roller gear cam) and a turret (output shaft) fitted with roller followers. The roller followers are preloaded against a screw-like input shaft to completely eliminate backlash. Our proprietary adjustment mechanism provides optimum preload.The roller followers planted in the turret use internal roller bearings to transfer torque while rotating. This ensures zero backlash, outstanding precision, and excellent efficiency without causing wear, while providing long-term consistent accuracy.

Exclusive zero-backlash construction

Features

No backlash (play).

High accuracy and good efficiency.

Preloadable for high rigidity.

Clampless machining reduces positioning time.

No deterioration of accuracy over time, initial accuracy is maintained for an extended period.

CNC RCDseries

Air supply

Sankyo's CNC rotary tables come 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.

(Do NOT block the exhaust outlet.)

Lubrication

Sankyo's CNC rotary tables use high-performance lubrication oil. Although the lubricant is chemically and thermally

stable, it should be changed every 3,000 hours of operation in order to ensure longer product life. Even if operated less

than 3,000 hours, the oil should be changed once per year. The condition of the oil can be checked with the oil level

gauge while the unit is in the stop condition. Check the oil level and color. If the level is low or the color has changed,

change the oil regardless of the number of operation hours. Some air bubbles may form in the oil during operation. This

is normal and does not affect quality.

* Be sure to use only the lubricant specified below. Otherwise service life may be reduced and parts may deteriorate.

Specified lubricant: Mobil SHC629 (VG150)

Use in grinding machines

When used in grinding machines, the seal device on the outer periphery of the table may become damaged. The

warranty does not cover such damage.

Maximum rotation speed

The maximum rotation speed for the table given in the specifications refers to the indexing speed. Consult with Sankyo

if the table is to be rotated continuously. Otherwise, the table will heat up and lose accuracy, causing overload alarms

with the servo motor.
