Abstract
A grinding bar for superfine machining is proportionally prepared from Cu, Zn, Ag, Al, In and artificial diamond particles through proportionally mixing, cold die pressing and vacuum hot pressing. Its advantaegs are short machining time, high size precision and long service life.
Description
Technical field
The present invention relates to a kind of ultrahard compounded tool and preparation method thereof, relating in particular to a kind of is the hone stone and preparation method thereof of raw material with the diamond.
Background technology
Hone is widely used in mechanical processing industries such as cylinder, oil cylinder, compressor, the processing of accurate interior circle, this product is long with efficient height, life-span, the machining accuracy height is an advantage, traditional carborundum honing stone will progressively be replaced, its life-span is about 500 times of traditional grinding tool, efficient is more than 2 times, and roughness can improve 2～3 grades, is the desirable machining tool of cylinder, oil cylinder, compressor, fine grinding cylinder, polishing.
As everyone knows, cubic boron nitride (CBN) and diamond are superhard materials, be mainly used in the processing of non-ferrous metal and nonmetallic materials with the sintered carbide tools of diamond fabrication, people use metallic bond usually, organic resin bond and vitrified bond are made the diamond hone stone, several indexs below good and bad main investigation of the hone stone that uses on the honing machine production line: process time, dimensional tolerance, roughness and service life, used in the market hone stone, basically all be some or two indexs better, therefore existing hone stone is further improved.
Summary of the invention
The object of the present invention is to provide a kind of honing bar for ultrafine processing 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:
A kind of honing bar for ultrafine processing, its composition and fill a prescription as follows:
Copper 60%～80%
Tin 10%～25%
Silver 0～10%
Aluminium 0～10%
Indium 0～1%
Phosphorus 0～2%
Diamond 0.05%～2%
Wherein the particle size range of diamond is 300 orders～1000 orders, and above percentage is percetage by weight.
This honing bar for ultrafine processing, its preparation technology is as follows:
Adopt craft or batch mixer to carry out batch mixing by proportioning metallic bond and diamond; Mixed raw material is adopted the two-way pressurization of powder metallurgical technique in the cold-work die steel mold, make the densification of product uniform microstructure, mechanical strength height, pressing pressure is 25～35MPa.And then in the high strength graphite mould, carry out vacuum hotpressing, and wherein hot pressing temperature is 550～650 ℃, and hot pressing time is 2～5 minutes, and pressing pressure is 2～4MPa, and vacuum is 1 * 10
-3Pa.
Because the present invention has selected suitable prescription and technology for use, the hone stone of producing has the characteristics of composite requests such as satisfying process time, dimensional tolerance, roughness, life-span simultaneously, compare with other hone stone, reduce by 1/2～1/3 process time, improve 2～3 times of life-spans.It is supporting that product of the present invention can be used for the streamline of import honing machine of similar processing compressor of air conditioner end cap.
