This product series is ideally designed for laser precision processing and they can also act as 3D scanning measurement systems. The device has many features such as a stepping motor drive and automatic end angle adjustment. Its worm and worm wheel are designed to provide durability and accurate rotation. The instrument incorporates high precision, ultra steel axis for precision and high load stable motion. Its outer circle features a scale. It is suitable for signals output using its standard interface. The device can achieve closed-loop control using its circle grating, encoder and MC series control box. Its three phase stepper motor and servo-motor are under plan.
