Abstract
The invention discloses on a kind of diamond disc for specialty cuts granite, comprise the following raw materials by weight percent:Copper powder 28% 42%, nickel powder 6% 15%, glass putty 6% 15%, K100 ultra-fine alloy powders 28% 42% and UT alloyed powders 12% 24%, diamond 1.2% 1.8%, wherein K100 superfine alloys meal component:Fe 48%‑60%、Co22%‑34%、Cu18%‑26%;UT alloy meal components:Cu 24%‑35%、Fe 48%‑56%、Sn 4%‑10%、Co 4%‑10%.Cutting speed of the present invention is fast, and cutting is not easy to generate heat and block, and is easy to control, is not easy to burn piece, can continuously cut for a long time, and cutting speed keeps stablizing.
Description
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.
