en.Wedoany.com Reported - On July 4, the YHDM580H precision CNC vertical double-end surface grinding machine and the YHMGK1720 precision CNC multi-functional cylindrical grinding machine, both independently developed by China's Yuhuan CNC, were included in the list of typical innovation cases for machine tools released by the Equipment Industry Development Center of the Ministry of Industry and Information Technology.
Machine tools are regarded as the core foundation of manufacturing modernization. This selection of typical cases, following processes such as enterprise applications and expert reviews, focused on domestically produced high-end machine tools with strong technological originality, high industrialization maturity, and demonstration and promotion value.
Both grinding machines were developed by Yuhuan CNC in collaboration with universities through an industry-academia-research model. Their overall technology has reached internationally advanced levels, with multiple core processes achieving world-leading status. This helps fill gaps in domestic precision machining equipment and accelerates the import substitution of key equipment in critical fields.
The YHDM580H precision CNC vertical double-end surface grinding machine adopts a vertical box structure, equipped with a micron-level large-diameter double-nut ball screw precision feed system and a self-adapted intelligent CNC system. It can perform simultaneous double-end surface grinding on metal and hard-brittle thin workpieces such as bearings, gears, silicon carbide, and sapphire, achieving micron-level parallelism and flatness. It supports integration with automated production lines and is suitable for batch manufacturing of precision components in new energy and consumer electronics sectors.
The YHMGK1720 precision CNC multi-functional cylindrical grinding machine features a dual-grinding-wheel switching technology for multi-process composite grinding of silicon carbide ingots, which is at a world-leading level. With a single clamping, it can complete multiple processes such as cylindrical grinding, crystal orientation positioning, and V-groove grinding for silicon carbide and sapphire ingots. Equipped with a direct-drive closed-loop spindle and a built-in crystal orientation detection module, it reduces machining errors caused by repeated clamping, making it a core domestic equipment in the third-generation semiconductor material processing field.
As a national-level specialized and innovative enterprise, Yuhuan CNC has long focused on precision grinding equipment. It has established multiple innovation platforms, including an enterprise technology center, an engineering research center, and an industrial design center. Continuously deploying in precision manufacturing fields such as aerospace, new energy, semiconductors, and the automotive industry, it has achieved industrialization for over 100 self-developed grinding machines. The company plans to use this as a new starting point to continue tackling core precision grinding technologies, drive the iterative upgrade of domestic high-end machine tools, support the self-sufficiency and control of high-end manufacturing, and provide equipment support for the cultivation of new productive forces.
