Description

A kind of diamond disc for cutting granite

Technical field

The invention relates to a kind of diamond discs for cutting granite.

Background technology

The diamond disc of condiments is ground by diamond, because of its excellent grinding performance, is widely used in precision optical machinery, The processing of the new materials such as photoelectricity information material, magnetic material, function ceramics is the industries such as machinery, automobile, electronics, aviation, national defence Indispensable machining tool.In the prior art, the cutter tooth materials'use iron-binding agent of most diamond discs is matched somebody with somebody Side is well bonded diamond tool tool, has good economic performance, but shortcoming is it is also obvious that i.e. high in cutting During hardness granite, continuously dry for a long time use can not be cut, under anhydrous conditions, can be generated at saw blade cutter tooth cut point Usually there is phenomenon of " striking sparks " using the product of iron-based in 1000 DEG C of high temperature, and spark is very big during cutting, and What is more, can cause Saw blade " burning tooth ", so as to be normally carried out cutting.

The content of the invention

The technical problem to be solved by the present invention is to：Grinding is not sharp during existing diamond disc cutting granite, effect Rate is low, and is ground easily fever and blocks, dry to be difficult to control when cutting, it is impossible to and it is continuous to cut for a long time, under processing precise degree.

In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：By the raw material group of following weight percent Into：Copper powder 28%-42%, nickel powder 6%-15%, glass putty 6%-15%, K100 ultra-fine alloy powder 28%-42% and UT alloyed powder 12%-24%, Diamond dust 1.2%-1.8%；Wherein K100 superfine alloys meal component includes Fe 48%-60%, Co22%-34%, Cu18%-26%; UT alloy meal components: Cu 24%-35%、Fe 48%-56%、Sn 4%-10%、Co 4%-10%.

Further, the present invention comprises the following raw materials by weight percent：Copper powder 32.5%, nickel powder 10%, K100 are ultra-fine Alloyed powder 32%, UT alloyed powders 16%, glass putty 8% and diamond dust 1.5%；The K100 superfine alloys meal component:Fe 50%- 57%th, Co22%-26%, Cu 20%-24%, rare earth element 0.2%-0.5%;The UT alloys meal component: Cu 24%-30%、Fe 48%-56%、Sn 4%-10%、Co 4%-10%。

Further, comprise the following raw materials by weight percent：Copper powder 32.5%, nickel powder 10%, K100 ultra-fine alloy powders 32%, UT alloyed powder 16%, glass putty 8% and diamond dust 1.5%；The K100 ultra-fine alloy powders are by following weight percent raw material Composition：Fe 53.7%, Co 26%, Cu 20%, UT alloyed powders described in rare earth element 0.3%. are by following weight percent raw material group Into：Cu 28%、Fe 56%、Sn 6%、Co 10%.

Present invention has the advantages that：Adding in K100 ultra-fine alloy powders makes powder carcass more easy-sintering, makes carcass finer and close, The mechanical strength of carcass is improved, carcass is improved to the hold of diamond, reaches higher cutting speed with less diamond And the service life；UT alloyed powders are added in, can further improve the alloying of carcass, saw blade is improved to the wettability of stone material, makes cutting When have better feel.The formability of metal powder, processing easy to produce can be increased by adding in copper powder.The K100 superfine alloys of addition Powder and UT sintering alloy powders form, and ensure that diamond disc cutting speed is fast, and cutting is not easy to generate heat and block, easily Control, is not easy to burn piece, can continuously cut for a long time, and cutting speed keeps stablizing.
