Each machine is carefully welded and spliced to ensure that the machine is more solid.

Every plate welding machine is subjected to high temperature heat treatment to relieve stress

After annealing process, the machine is finished by gantry center milling

Each screw on the machine is tightly locked according to the standard torque

Laser collimator detects the straight line of guide rail

The precision of each rack screw point and two rack joints should be controlled within 0.01mm

The vertical accuracy error of X axis and Y axis is controlled within 0.01mm

After installation and debugging, the laser interferometer is used for secondary calibration, detection and precision compensation

The equipment must be tested continuously for 72 hours before leaving the factory for strict testing
