Second, product features:
※ Standard stepper motor and RS232 interface, the company's self-developed motion controller can realize automatic control;
※ Small and thin structure, suitable for use in light load, low speed, and scientific experiments; High quality fine grinding screw drive, small lead, the same fine fraction can achieve high resolution;
※ Ingenious design of empty return nut structure can reduce the clearance of grinding lead screw pair to a minimum;
※ Precision square guide rail, comfortable movement, with the function of lateral adjustment of guide preload and clearance, can be used in multiple dimensions;
※ The ground plate and reasonable guide rail fixing method greatly reduce the pitch and deflection of the station, so that the straightness and parallelism of the movement are greatly improved.
