Abstract
The invention discloses a honing tool with cubic boron nitride as a raw material, and a production method thereof. The honing tool is composed of copper, tin, iron, silver, manganese, silicon, titanium and cubic boron nitride. The honing tool is produced by mixing, thermally forming and secondarily sintering the raw materials in a vacuum way. The honing tool produced by the invention has the advantages of high density and long service life. The honing tool can be used for honing holes, such as the large and small holes of the connecting rod of an automobile.
Description
Technical field
The present invention relates to a kind of composite superhard material instrument and preparation method thereof, relating in particular to a kind of is the hone and preparation method thereof of raw material with the cubic boron nitride.
Background technology
The honing processing method is a kind of a kind of high-efficiency machining method that makes workpiece machining surface reach high accuracy, great surface quality, high life, is widely used among the fields productions such as automobile making, space flight and aviation, mechanical machine tool, military and national defense.Its hone will progressively replace traditional carborundum oilstone with efficient height, the life-span is long, machining accuracy is high advantage, is the ideal tools of high accuracy parts such as processing automobile connecting rod.
As everyone knows, cubic boron nitride (CBN) is a kind of superior superhard material, because the cubic boron nitride hone is regardless of its prescription, can be hot-pressed to density (metallic bond) near 100%, reduced because the caused performance variation of sealed porosity, thereby with sintered carbide tools machining tool steel, mould steel, hardened steel and the various steel alloy long service life of cubic boron nitride manufacturing, the processing work roughness is low, precision is high, working (machining) efficiency is high, dimensional tolerance is worked good.
Summary of the invention
The object of the present invention is to provide a kind of cubic boron nitride hone of new prescription;
Another object of the present invention is to provide the preparation technology of this hone.
Goal of the invention of the present invention is achieved by the following technical solution:
