Domestic Development: From Introduction to Independent BreakthroughThe development of domestic equipment started with technology introduction and imitation. In the early stage, it relied on hydraulic transmission and manual adjustment, with a machining accuracy of only ±15μm, and core technologies and components were imported for a long time. Driven by intelligent manufacturing policies and market demands, it has realized the leap from mechanical control to numerical control, and technologies such as multi-axis linkage and AI intelligent lapping have been put into application.
Today, sub-micron level precision breakthroughs have been achieved, and some technologies have reached the international advanced level. The localization rate rose to 41.3% in 2023, forming a complete industrial chain supporting system.

Comparison of Domestic and International Technologies
3.1 International Technical Advantages
Enterprises from Europe, America and Japan dominate the high-end market, with core advantages as follows:
① Precision transmission and closed-loop feedback technology achieve ±0.5μm positioning accuracy, suitable for extreme application scenarios;
② Integrating functions such as lapping plate constant temperature control and real-time thickness measurement, with strong operational stability;
③ Mature special processes for hard and brittle materials, with outstanding efficiency and yield rate.
3.2 Domestic Technical CharacteristicsThe accuracy of mainstream models reaches ±0.5μm, with surface roughness ≤0.0005μm, which can replace imported equipment in some scenarios. The advantages are concentrated in:① Intelligent innovation: The defect recognition rate of AI visual inspection exceeds 99%, and energy consumption is reduced by 30%;② Significant cost performance: The price is 30%-50% of that of imported products, with strong competitiveness in the mid-to-high-end general market.
3.3 Existing GapsThere are deficiencies in the reliability of high-end core components and the processing consistency of large-size workpieces. High-precision sensors rely on imports, and the long-term stability of complex material processing needs to be improved.
