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.

Table clamping

Application Serves for holding the table at the stop position during machining.

Recommended application After checking the in-position signal of the drive motor, output the clamp command for

the table clamp and check pressure with the pressure sensor. After a specific interval,

establish the clamp complete (positioning complete) state.

Using a machine tool

servo motor

In principle, servo should be ON, but it is recommended to make provision for servo to be

switched OFF if the table clamp was activated while unbalanced torque is generated and

the motor current exceeds 70% of the rated value. (The servo motor should be designed

for absolute movement and the operation commands must also be issued as absolute

values.)

Using a general type

servo motor

The following two types of servo motor control are recommended.

(1) If servo ON is to be maintained, change proportional integral control to proportional

control. This will prevent overload problems.

(2) If servo is to be set to OFF, the servo motor's coordinates would be lost if the servo

motor is designed for relative movement. To prevent this, an absolute movement type

servo motor must be used, and commands must be issued as absolute values.

Points to note The system is designed for the following operation sequence:

Air/Hydraulic pressure ON Clamp, Air/Hydraulic pressure OFF Unclamp. Clamping

can therefore not be performed when power or the air pressure source will go OFF.

Motor braking

Application Serves for holding the table at the stop position during power off or servo off.

Recommended application Use a servo amplifier or a servo ON/OFF signal from higher-level equipment to turn the

motor brake on or off. Braking operation is taken to be completed after a specific interval

has elapsed.

Using a machine tool

servo motor

The ON timing should be as follows. First use the servo ON signal to enable servo, verify

that servo is ON, then release the brake. After a specific interval for brake release has

elapsed, the operation is taken to be completed. The OFF timing should be as follows. Use

the servo OFF signal to set the brake to ON, and take servo OFF to be completed after a

specific interval has elapsed.

Using a general type

servo motor

Points to note Due to the characteristics of the motor brake function, it cannot be used for holding the

table in the stop position during machining or for table control.

Otherwise machining accuracy may be affected.

CNC rotary tableControl methods for air / hydraulic table clamping

Introduction

This section provides information as well as precautions about generally recommended control methods that can

be used with Sankyo CNC rotary tables that support air or hydraulic table clamping or motor braking.Because the

RollerDrive type CNC rotary tables do not have any structural backlash, clamping is not necessary within certain

conditions. This approach eliminates the time required for clamping and unclamping.It allows positioning at maximum

speed, while also consuming no energy for a air or hydraulic system.

However, if a very high holding torque to maintain the table at the stop position is required, table clamping can be

selected as an optional specification.

* In actual use, the characteristics of the equipment installed by the customer and the functions that are targeted are also relevant. Please

use the information provided here as a reference in setting up the appropriate control sequence for the specific application.

Precautions

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.
