Description
Technical field
The present invention relates to a kind of diamond disc, especially a kind of cutting and grinding material diamond disc, category
In powdered metallurgical material technical field.
Background technology
In existing diamond tool, W, WC, W are added sometimes2The high-abrasive materials such as C are used to carry as framework material
The hardness and wearability of saw blade tip high, so as to improve the service life of saw blade.But due to W, WC, W2C has high-melting-point, height
The characteristic of hardness, poor with carcass metal wellability, it is difficult to sinter, this results in carcass to holds such as W, the WC as wear-resisting phase
Not enough, it is wear-resisting compatible easy to fall off in use, substantially reduce the life-span of saw blade.Simultaneously in traditional diamond disc
The addition of the wear-resisting phase such as middle WC, W is difficult more than 60%, because with the increase of the additions such as W, WC, the compactness of cutter head sintering
Decline, cutter head density reduction, the hard fragility of cutter head increases, and intensity declines, easily occur the tight of cutter tooth fracture in cutting process
Weight consequence.Therefore, W, WC, W are added in diamond cutter2The high-abrasive materials such as C are restricted, it is impossible to largely use, cause gold
The anti-wear performance of diamond saw blade is not high.
The content of the invention
The technical problem to be solved in the invention provide a kind of cutter head hardness and wearability it is good, being capable of cutting and grinding material
The diamond disc of material.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of cutting and grinding material diamond disc, the cutter head of diamond disc is mixed by cutter head carcass with diamond
After be made；Surface coating is added in cutter head carcass the high-abrasive material of metal cobalt powder, and the high-abrasive material is WC, W, W2In C
One or several.
Further, the weight that Surface coating has the high-abrasive material of metal cobalt powder account for cutter head carcass percentage by weight for 5%~
80%, remaining is the mixture of Cu powder, Fe powder and Sn powder.
Further, it is 20% that the weight that Surface coating has the high-abrasive material of metal cobalt powder accounts for cutter head carcass percentage by weight
~70%, remaining is the mixture of Cu powder, Fe powder and Sn powder.
Further, high-abrasive material is WC and W2The mixture of C.
Further, high-abrasive material is the mixture of WC and W.
Further, high-abrasive material is W and W2The mixture of C.
Further, high-abrasive material is W, W2The mixture of C and WC.
By adopting the above-described technical solution, the present invention achieves following beneficial effect：
The present invention is using Co powder and WC, W, W2The wear-resisting phase material such as C and excellent with the cutter head carcass material compatibility such as Cu, Fe
The characteristics of, by the use of Co powder as middle transition binder course, carcass can be increased to W, WC, W2The hold of the wear-resisting phase such as C, it is wear-resisting
Difficult for drop-off in the process of use, giving full play to wear-resisting phase can strengthen the effect of saw life.
The present invention overcomes WC, W, W in diamond disc by adding Co powder2The addition of the wear-resisting phase such as C is difficult
Problem more than 60%, Co claddings WC, W, W2The use of C powder can improve wear-resisting with carcass interface affinity, promote to burn
Knot, improves the toughness and bending strength of cutter head, increases the addition of wear-resisting phase and then the service life of raising saw blade.
The present invention can add WC, W, W of any content by adding Co powder according to the demand of wearability2The wear-resisting phase such as C,
Corresponding diamond saw blade can be according to demand made, diamond disc has been given full play on the premise of use is not influenceed
Cutting performance.

The present invention overcomes WC, W, W in diamond disc by adding Co powder2C etc. as wear-resisting phase wear-resisting material
The addition of material is difficult the problem more than 60%, in the present invention WC, W, W2The addition maximum of C can reach and account for cutter head carcass matter
Amount 80%, expand significantly diamond disc for varying strength abrasiveness material cutting when adaptability.
Co claddings WC, W, W in the present invention2The use of C powder can improve wear-resisting with carcass interface affinity, promote to burn
Knot, improves the toughness and bending strength of cutter head, increases the addition of wear-resisting phase and then the service life of raising saw blade.WC、W、W2C
Deng high-abrasive material as the wear-resisting anti-wear performance for being added in diamond segment and can improving diamond segment, extend diamond
The service life of saw blade.
The present invention is using Co powder and WC, W, W2The high-abrasive materials such as C and with other cutter head carcass material compatibilities such as Cu, Fe
Excellent the characteristics of, by the use of Co powder as middle transition binder course, carcass can be increased to W, WC, W2The holding of the wear-resisting phase such as C
Power, wear-resisting difficult for drop-off in the process of use, giving full play to wear-resisting phase can strengthen the effect of saw life.After adding Co powder,
The sintering process of diamond segment is more prone to.Meanwhile, Co powder accounts for the addition of high-abrasive material as middle transition binder course
Cutter head carcass mass fraction is arbitrary value, and the weight of high-abrasive material accounts for cutter head carcass weight hundred in 1~embodiment of embodiment 10
Divide than being 5%~80%, the weight that can as needed adjust high-abrasive material accounts for cutter head carcass percentage by weight to make with not
With the diamond disc of anti-wear performance, so as to cut the abrasiveness material of different hardness.
The invention provides cost performance it is high, performance is excellent, suitable for the diamond circular saw of cutting and grinding material
Piece.
