Shenyang Changpu Superhard Precise Tools Co., Ltd. (the former Shenyang Ruichen Superhard Materials Factory), established in 1990, is specialized in the production of diamond and CBN superhard precise tools. It is located in Minzu Economic & Technological Development Zone in the southwest of Shenyang, the heavy industry base of China, covering a plot area of 2,100 sq. m and having a building area of 2,000 sq. m. It has a competent professional team with strong technical force, advanced production process and perfect testing measures. Our products have a wide range of specifications, almost covering all application fields of DIA and CBN tools. In the past 15 years, our high quality products and sincere service have won us great popularity and prestige from broad customers.
Our products DIA and CBN superhard precise tools include resin/metal/electroplated/vitrified bonded grinding wheel, high precision and complex-profile cutting tool, grinding tool, milling tool, drilling tool, grinding disk, cutting saw blade, center, reamer, roller, dresser, oil stone, honing stone, file and abrasive paste, etc. nearly one hundred varieties and specifications, which are widely used for abrasive machining for such highly hard materials that are difficult to process and require high precision, such as hard alloy, optical glass, crystal, quartz, fine ceramics, ferrite, polycrystalline diamond and polycrystalline CBN compact, gem, semiconductor, refectory, shell, carbon and graphite products, plastic, wear-resistant metal, tool steel, quenched steel, structural steel, stainless steel, high-hardness cast iron, heat-resistant metal, high precision cylinder, precision machinery, etc. in a wide range of sectors. We are willing to serve old and new customers and promote the social material progress.

Research and innovation is the core force to impel the development of enterprise. Based on technical innovation on conventional products, we focus on the new trend of superhard processing and develop corresponding new type superhard tools, such as high quality metal-bonded quality honing stone, high precision-ultrathin-complex profile metal-bonded diamond cutters, special grinding and milling and drilling tools of precision center of numerical control (CNC), which all reach the international advanced level and can substitute those imported, extensively used in the processing of quartz ware, fine ceramics, various superhard materials and new-type nanometer structural materials, etc. in car in the industries of car, machinery, petrochemical and semiconductor materials. We are among the few manufacturers in China who are capable to undertake the production of such superhard tools.
We always supply high quality products at moderate price with timely delivery. Standard products and non-standard products are both available upon customer demand. You are welcome to cooperate with us for mutual development!

We strongly recommend our DIA and CPN precision tools, which were developed by us with the state-of-the-art technology. These tools can well meet your requirements in manufacturing and material processing.
Sincerity makes superiority, hard work makes hard tools! You are welcome !
