 High Precision Motorized Rotation Stages using

New construction ,new technology;the key index has up to the international level of the similar products by strictly inspection .This series products are used to laser precision processing,three dimensional scanning measurment system and so on .

Worm and worm wheel has adopted durable to friction material ,high reliable accuracy of rotation .

High precision ,ultra steel axises of importing ,achieve high precision, high load stable motion.Outer circle has scale, interface , convenience for signal’s output.


Standard stepper motor and DB9 interface, choose to controller flexibility ,We also can provide fully customized motion systems .

Regular stage set with stepper motor and RS232 interface, could connect with motion controller easily.


*High precision Worm gear design for high accuracy, loading and long working time.

*Forward and reverse rotate are possible

*The stage could use in vertical and assemble with other stages


1. Prototype stepper motor42 stepper motor (1.8°). Servo motor available for replacement on request

2. Fine steel rotary shoe, high accuracy, massive loading capacity and long using life.

3. Fine grinding worm drive with comfortable movement and backlash can almost ignored.

4. Clearance elimination design.

5. The motor is connected with the worm via high quality elastic coupling, synchronized drive without noise.

6. Scaling on the outerring of the platform, easy scale reading.
