Granite Precision Machined Component Accuracy (Official Standards Industry Real-World Testing)The machining accuracy of granite precision components can reach up to Grade 000, with flatness ≤0.5μm/m and dimensional accuracy ±1μm, classified as ultra-precision grade. I. Accuracy Grades (National Standards / Industry General)Grade 000 (Highest)Flatness: ≤0.5μm/mApplications: CMMs, roundness testers, semiconductor optical bases, ultra-precision inspection platforms Grade 00…

The core of machining precision granite components lies in an ultra-precision control process spanning “from raw material screening to closed-loop precision,” requiring strict control over parameters, equipment, and environment at every stage to ultimately achieve micron and even sub-micron level accuracy. The following are 8 core processes, each supplemented with industry standard data, equipment parameters,…
