Precision machining and micro-machining technology are important development directions in the machinery manufacturing industry.

Precision machining and micro-machining technologies are important development directions in the machinery manufacturing industry, and they have become significant indicators of a country's high-tech level. The development of various cutting-edge technologies and the defense industry cannot be separated from precision machining and micro-machining technologies. Contemporary precision engineering, micro-engineering, and nanotechnology are the pillars of modern manufacturing technology. Additionally, many new electromechanical products, including micro-electromechanical products, require improved precision and reduced scale to promote the overall technological advancement of the machinery manufacturing industry, significantly enhancing the quality, performance, and reliability of mechanical products. Precision machining and micro-machining technologies are comprehensive technologies that integrate multiple disciplines, including machinery, electronics, optics, computer control technology, and new materials. Among materials, natural granite is receiving increasing attention due to its inherent properties. Using high-quality stones like natural granite for precision mechanical components is a new direction for the development of precision measuring instruments and precision machinery. Many industrially developed countries, such as the United States, Germany, Japan, Switzerland, Italy, France, and Russia, widely use granite as measuring tools or components of precision machinery. Granite platforms and granite component products not only have a large domestic demand but also see an increasing export volume year by year. Data indicates that the total procurement of granite platforms and component products is increasing annually in countries such as Germany, Italy, France, South Korea, Singapore, the United States, and Taiwan.
