1) forming a world-class ultra-precision surface grinder. 
 2) The standard configuration from top to bottom, before and after the two-axis high-precision linear scale (0.0001mm) and the actual position of the monitor. 
 3) All manual guide face and the contact surface scraping, the world's only this one. 
 4) ensure the mechanical accuracy of the upper and lower tracking precision and recovery ± 0.001mm or less (10 years), only this one world. 
 5) μ-class 0.2μm phase feed grinding and grinding, mirror grinding easily achieved (Ry0.3μm or less).
