Abstract

The invention discloses a mixed ultra-hard abrasive honing stone. The mixed ultra-hard abrasive honing stone is characterized by comprising the following components in percentage by weight: 20-40 percent of copper, 2-6 percent of silver, 1-10 percent of aluminum, 2-6 percent of zinc, 2-20 percent of tin, 10-20 percent of iron, 5-10 percent of nickel, 5-30 percent of cobalt, 1-9 percent of lead, 5-10 percent of a bonding agent and the balance of an ultra-hard material, wherein the volume ratio is 60-100 percent; the metal purity of the copper, the silver, the aluminum, the zinc, the tin, the iron, the nickel, the cobalt and the lead is over 99 percent; the granularity of the ultra-hard material is 200-1,000 meshes; the honing stone is prepared by performing mixing, cold press molding and vacuum hot press process on the raw materials according to the mixture ratio. The mixed ultra-hard abrasive honing stone disclosed by the invention has the advantages of sharp grinding, high grinding efficiency, large grinding weight, short grinding time, long service life, superior self-sharpening property, low process cost, easiness and convenience in preparation, and the like.

Description

technical field [0001] The invention relates to a mixed superabrasive honing oilstone and a preparation method thereof. Background technique [0002] Honing is a method of finishing the surface of the workpiece at a low cutting speed, and is a special form of grinding. As a finishing method to improve the machining accuracy of the inner hole surface and reduce the surface roughness, honing can not only remove a large machining allowance, but also improve dimensional accuracy, geometric shape accuracy and reduce surface roughness, so it is widely used It is used in the finishing process of hole parts in industries such as automobile, aviation, petroleum machinery, engineering machinery and military industry. [0003] As the most commonly used honing process, honing stone is widely used in grinding processing. As one of the main factors affecting the honing inner hole surface quality and honing efficiency, the honing oil stone has the most direct impact on the grinding perfo...
