2 The Ultimate N Rotary Table Zero-backlash Technology elivers Unsurpassed Motion The Rollerrive N is a rotary table designed to meet the requirements of machine tool manufacturers for greater speed and accuracy. The Rollerrive 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 1 seconds or less, and can hold up to heavy cutting forces on hard steel. The heavy-duty Rollerrive N 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 Rollerrive The Rollerrive 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 Preload mechanism Turret (output) Roller gear cam (input) am followr eatures Rolling contact Preload No backlash (play). High accuracy and good efficiency. Preloadable for high rigidity. lampless machining reduces positioning time. No deterioration of accuracy over time, initial accuracy is maintained for an extended period. 1

18 N rotary table ontrol 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 N rotary tables that support air or hydraulic table clamping or motor braking.ecause the Rollerrive type N 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. Table clamping pplication Recommended application Using a machine tool servo motor Using a general type servo motor Points to note Serves for holding the table at the stop position during machining. fter checking the in-position signal of the drive motor, output the clamp command for the table clamp and check pressure with the pressure sensor. fter a specific interval, establish the clamp complete (positioning complete) state. In principle, servo should be ON, but it is recommended to make provision for servo to be switched O if the table clamp was activated while unbalanced torque is generated and the motor current exceeds 7% of the rated value. (The servo motor should be designed for absolute movement and the operation commands must also be issued as absolute values.) 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 O, 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. The system is designed for the following operation sequence: ir/hydraulic pressure ON lamp, ir/hydraulic pressure O Unclamp. lamping can therefore not be performed when power or the air pressure source will go O. Motor braking pplication Recommended application Using a machine tool servo motor Using a general type servo motor Points to note Serves for holding the table at the stop position during power off or servo off. Use a servo amplifier or a servo ON/O signal from higher-level equipment to turn the motor brake on or off. raking operation is taken to be completed after a specific interval has elapsed. The ON timing should be as follows. irst use the servo ON signal to enable servo, verify that servo is ON, then release the brake. fter a specific interval for brake release has elapsed, the operation is taken to be completed. The O timing should be as follows. Use the servo O signal to set the brake to ON, and take servo O to be completed after a specific interval has elapsed. ue 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. 17

30 Precautions ir supply Sankyo's N rotary tables come standard equipped with an air purge outlet. (Use it to blow out condensation and Pressure setting:.2 MPa ir consumption: 1 L/min coolant to prolong the life of electrical parts and prevent rust in the motor housing.) Supply clean air for the air IN purge by referring to the drawing shown. (o NOT block the exhaust outlet.) OUT ir combination 2-1G- (SM) (Pressure Gauge G36-2-1) *Reference Model Lubrication Sankyo's N rotary tables use high-performance lubrication oil. lthough the lubricant is chemically and thermally stable, it should be changed every 3, hours of operation in order to ensure longer product life. Even if operated less than 3, 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. heck 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. * e sure to use only the lubricant specified below. Otherwise service life may be reduced and parts may deteriorate. Specified lubricant: Mobil SH629 (VG1) 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. onsult 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.
