Pragmatism·Innovation·Excellence
Digital Connectivity, Intelligent Manufacturing Empowerment. The 14th China International CNC Machine Tool Exhibition (CCMT2026) will grandly open from April 21-25 at the Shanghai New International Expo Center. This Asia's largest professional machine tool and tooling event will gather over 2,000 enterprises from 27 countries and regions, themed "Digital·Interconnection·Intelligent Manufacturing," to jointly outline a new blueprint for precision manufacturing. Henan Shili Diamond Products Co., Ltd., with over 30 years of craftsmanship and innovation in the superhard materials field, cordially invites new and existing clients, as well as industry peers, to visit our booth, discuss collaboration, and embark on a new journey toward intelligent manufacturing.
Wisdom Converges in Chongqing, Craftsmanship Embarks on a New Journey. As a UFI-certified professional exhibition, the 26th Lijia International Intelligent Equipment Exhibition will grandly open from May 28 to 31, 2026, at the Chongqing International Expo Center (Yuela).
Henan Shili Diamond Products Co., Ltd., founded in 1992 and formerly known as Luohe Natural Diamond Products Factory, was established in 2003 with a registered capital of 12 million yuan and assets of 40 million yuan. It is a national high-tech enterprise that integrates research and development, production, and sales of diamond products.
Henan Strength：With diamond, we can handle porcelain work, and technological innovation welcomes a good start!
The core of precision manufacturing lies not only in the refinement of craftsmanship, but also in the precise conservation of measurement. In high-end manufacturing scenarios such as bearing processing, automotive parts, precision gears, and semiconductor components, micrometer level error deviations may cause precision polished workpieces to lose their quality value. Many production pain points are not caused by processing equipment, but by hidden losses caused by probe wear, accuracy deviation, and data fluctuations in long-term high-frequency measurements. Diamond measuring claws, as the core supporting components of precision testing, break the performance limitations of traditional measuring accessories with the ultimate physical properties of natural diamonds, and build a long-term and stable precision defense line for industrial precision testing.
As the "rotating heart" of mechanical equipment, the raceway profile, arc precision, and surface waviness of bearings directly determine the operating noise, smoothness, and service life of the equipment. With the upgrading of the new energy, high-end machine tool, and heavy equipment industries, the market's demand for high precision, low noise, and high consistency of bearings continues to rise.
The core quality of a high-grade tap lies in its thread profile. The thread angle, pitch diameter accuracy, and surface finish directly determine the tapping performance, service life, and thread quality of the workpiece. In mass production of taps, wheel dressing is the most critical step in controlling thread grinding quality. Henan Shili specializes in superhard precision dressing tools, offering customized diamond wheel solutions to address the pain points of tap thread mass production, enabling tool manufacturers to achieve significant improvements in precision, efficiency, and yield rates.
Ball screws are core components for achieving precise transmission in automated equipment and precision machine tools. The thread groove profile, lead accuracy, and surface quality directly determine the positioning performance, operational noise, and service life of the equipment. Profile grinding is a critical process in the precision machining of ball screws, and the stability of wheel dressing becomes a key factor limiting the quality and production capacity of mass manufacturing. Henan Shili specializes in the R&D and customization of diamond grinding wheels, providing integrated profile dressing solutions for the ball screw manufacturing industry.
Linear guides and sliders, as fundamental moving components of automated equipment, CNC machine tools, and smart production lines, have their rolling surface arc precision and surface finish directly determining the smoothness of operation, load-bearing capacity, and service life of the equipment.
In the precision machining workshop, few pay attention to the dressing tools behind the grinding wheels, yet it is a small diamond wheel that steadfastly maintains the baseline of component accuracy and mass production capacity.
