Hardware advantages: 1. Grating ruler is one of the most critical hardware determining instrument accuracy. Our company uses the world's top brand, Heidenhain from Germany, with an accuracy of 0.001mm. 2. Servo motor control transmission is used. High precision, precise positioning. Good quality, not easily damaged. There is no noise during operation. 3. The workbench is made of 7075 aviation aluminum imported from the United States, which is lightweight, fast in operation, and does not deform. 4. The transmission method is high-precision grinding grade ball screw and P-stage linear guide, which runs smoothly, has precise positioning, and can assist software in quickly capturing images. 5. Granite base and columns have stable expansion physical properties, high precision, and no deformation. 6. WeimiDD fully automatic 0745 continuous zoom lens, which can automatically switch measurement magnification in the program
