Cubic boron nitride ceramic binder parallel abrasion wheel and its production method

Abstract

A flat adhesive disk for grinding the workpiece made of high-speed steel is prepared from cubic boron nitride, dextrin powder, white corundum, wetting agent and ceramic adhesive through proportional mixing, shaping, drying, sintering, examining and trimming. Its advantages are high hardness, toughness, high-temp strength and antiwear performace and long service.

Description

1. Technical Field [0001] The invention relates to a cubic boron nitride ceramic bond parallel grinding wheel for processing high-speed steel difficult-to-wear parts and a production method thereof. 2. Background technology [0002] The rapid development of science and technology has provided rich cultural entertainment and material conditions for people’s lives, but at the same time, it has put forward higher requirements for the production and processing of new products, such as high-speed high-speed systems that have been widely used in the production of air conditioners and refrigerators. Steel wear parts, such as the core components of air conditioners and refrigerators. The crankshaft, rollers, sliders, upper and lower covers of refrigeration compressors all require high precision. Abrasives originally made of silicon carbide and corundum have low processing efficiency and frequent repairs. , And the roughness is difficult to meet the requirements, the produced compressors ...

Problems solved by technology

[0002] The rapid development of science and technology has provided rich cultural entertainment and material conditions for people's lives, but at the same time it has put forward higher requirements for the production and processing of new products, such as high-speed motors that have been widely used in the production of air conditioners and refrigerators Steel wear-resistant parts, such as crankshafts, rollers, sliders, upper and lower covers of refrigeration compressors, which are the core components of air conditioners and refrigerators, all require high precision. The original abrasive tools made of silicon carbide and corundum have low processing efficiency and frequent dressing , and the roughness is difficult to meet the requirements, the compressors produced are noisy, short in life, and high in cost. Imported compressors are expensive and difficult to be accepted by people, especially with the continuous emergence of new materials and the continuous expansion of the range of machining, Processing quality requirements are higher, so how to solve the needs of high-quality, high-precision, high-efficiency, and low-cost machining?
