The four special funds projects of the Ministry of Science and Technology undertaken by Zhengzhou Sanmao Institute passed the appraisal

This station news (correspondent Zhang Geqi reported) On April 6, 2011, the China Machinery Industry Federation organized experts to hold the Ministry of Science and Technology undertaken by Zhengzhou Abrasives Grinding Research Institute (Zhengzhou Sanmao Research Institute) in Zhengzhou. Special fund project for research and development of scientific research institutes, "New composite bond diamond grinding wheel for high hardness blade grinding", "Development of superhard material grinding disc for super-precision grinding ceramic bond", "High-speed ceramic CBN grinding wheel for automobile engine crankshaft processing" "" and "15 ~ 60μm ultra-thin diamond Cutting Wheel manufacturing technology research" and other projects such as the identification meeting. Among them, the project “New composite bond diamond grinding wheel for high hardness blade edging” is proposed according to the development trend of domestic grinding technology and market development demand. Its significance is to promote the development of blade CNC peripheral grinding technology and composite bonding agent. The peripheral grinding wheel of the blade is promoted and applied in the tool manufacturing industry, and through the development of the new composite bonding agent, the application level of the high-performance abrasive manufacturing technology and products including the peripheral grinding wheel of the blade is improved. "Development of Ultra-hard Grinding Ceramic Bonding Superhard Material Grinding Disc" The subject of the special low-temperature ceramic bond process formula and ceramic grinding disc mixing uniform granulation technology to prepare super-hard material ceramic bond grinding disc (pill sheet) ), developed the key technology of rapid bonding of ceramic pellets, optimized the resin composite filling technology, developed a ceramic bond superhard material grinding disc, and realized the one-time composite processing of grinding and polishing. The project is innovative in the ceramic binder homogenization smelting process, resin filler compound technology and grinding and polishing combination technology, and the overall technology has reached the international advanced level. The subject of "High-speed Ceramic CBN Grinding Wheel for Automobile Engine Crankshaft Machining" solves the problem of uniform forming of complex-faced grinding wheel by optimizing the design of the working layer structure and forming technology of complex-faced grinding wheel, and realizes different parts of the grinding wheel for precision forming grinding. Uniform wear, effectively improve the accuracy and efficiency of automotive engine crankshaft machining. The project is innovative in low temperature and high strength ceramic bond, grinding wheel structure design and preparation technology. The "15 ~ 60μm ultra-thin diamond cutting wheel manufacturing technology research" project developed a special electroplating device, through the use of pneumatic agitation and workpiece rotation combined with the optimization of plating solution formulation and electroplating process, to achieve uniform power of micron diamond Deposition; through the use of customized high-precision, micro-motion special ultra-precision air pressure chuck, the processing problem of high-precision internal hole and parallelism of aluminum alloy thin-plate workpieces is solved, and the machining and chemical corrosion technology are used to realize the cutting edge. Naked; developed a super-thin grinding wheel with a thickness range of 15~60μm, forming a high-end product for semiconductor and optoelectronic material processing. The project is innovative in the field of micro-scale diamond uniform electrodeposition, ultra-thin electroplated grinding wheel outer circle processing, blade edge exposure technology. The appraisal committee gave full affirmation and high evaluation to the technical achievements of the above four projects, and believed that all four projects have overcome relevant technical problems, improved the quality and performance of products, improved work efficiency, and both Substituting imported similar products, the economic and social benefits are very significant, and the market prospect is broad. The overall technology has been rated as internationally advanced.

Resin Bond Grinding Wheels

Resin Bond diamond and CBN Grinding Wheels are made of either phenolic or polyimide resins. Pressure and heat are utilized to bond the resin to our grinding wheel cores.
Phenolic bonded wheels can be utilized in dry or wet applications. Our polyimide bonded wheels are best utilized in water or oil-based coolants for improved form holding, typically required in CNC tool and cutter applications.

Resin bonded CBN Grinding Wheels are widely used on CNC machine for all tyeps of high speed steel cutter and drills machining and sharpening. They come mostly on shape of straight wheel of plat wheel, or bow shape wheel, or the working part can be sharpened to special shape like v shape or bevel shape.

A silicon carbide stone dresser is mostly used for the diamond or CBN grinding wheels.

Kemei produces all types and shapes diamond grinding wheels and CBN grinding wheels, and wheel dressers. If you need any grinding solution, contact us.
