Mingzheng (Zhejiang) Electronic Equipment Co., Ltd. specializes in the research, development, production, and sales of high-end single- and double-sided precision grinding and polishing machines, which are widely used in cutting-edge fields such as "piezoelectric crystals," "semiconductor substrates," and "precision optics." The core technical team has independently developed a range of high-precision single- and double-sided grinding and polishing equipment, including double-sided models such as 6B, 9B, 13B, 16B, 22B, 32B, and 40B, as well as single-sided models like 36B and 50B. The products are primarily applied in the grinding and polishing of non-metallic and metallic hard, brittle, and fragile thin precision components, such as LED sapphire substrates, electronic materials (silicon wafers, germanium wafers, etc.), ceramic substrates, optical glass, quartz crystals, liquid crystal displays, memory hard disks, and other semiconductor materials. After single- or double-sided precision grinding and polishing, the workpieces can easily achieve a flatness of 0.3 μm, parallelism of 1 μm, thickness variation of 1 μm, and surface roughness below 0.01 μm, meeting the production and processing needs of semiconductor chip manufacturing, high-precision ceramic components, precision optical parts, and precision mechanical components.

Driving enterprise high-quality development through technological innovation, we strive to contribute to China’s electronic information industry, precision optics, and semiconductor sectors with better product quality, upholding the reputation of "Made in China" and dedicating our efforts to "Created in China."
