Abstract
The present invention provides an abrasive material. The abrasive material takes metal corundum particles as abrasive particles. A binding agent is composed of the powder of a plurality of metals or metal compounds, and the abrasive material is formed by high temperature sintering. A new formulation is adopted by the present invention, and the compositions of the present invention are reasonable. The abrasive material is firmly stuck with the binding agent. The abrasive material is difficult to fall during use and has long service life. Compared with the existing diamond abrasive block with the same type, the present invention can improve work efficiency by 1 to 1.5 times. The present invention can be used for processing various hard materials such as marble, granite, waterstone, etc. The processing precision of the marble, the granite, the waterstone, etc. can be improved.
Description
The invention belongs to a kind of abrasive substance, specifically, be a kind of be the abrasive substance of abrasive particle with the diamond particles.
The diamond lap material is to be abrasive particle with the diamond particles, and it is mixed after pressure sintering forms with wedding agent, is mainly used to grind some mechanically resistant materials, as granite, marble etc.
Existing diamond grinding block, its wedding agent mostly are by powder constituents such as cobalt powder, nickel powder, ferrophosphorus powder and tungsten carbide powders.Because prescription is unreasonable, exists abrasive particle and combines not firm defective with wedding agent, in the use, diamond abrasive grain comes off easily, causes work-ing life short, and the processing work efficiency is low.A kind of matrix material and manufacture method thereof of the high-abrasive material that bonds are provided in the European patent document of the document number that now retrieves for EP0298593A2, but this invention has just been done qualification to particulate diameter in the material, its prescription does not have substantial change, thereby fails fundamentally to eliminate the existing defective of abrasive substance.
The purpose of this invention is to provide a kind of is the abrasive substance of abrasive particle with the diamond particles, and this abrasive substance is its diamond abrasive grain difficult drop-off in use, long service life.
Feature of the present invention is to contain by its weight percent meter:
Diamond 3.5-6.5%
Cobalt 30-60%
Copper 8-40%
Nickel 5-46%
Iron 1-6%
Tin 1-6%
Chromium 1-3%
Zinc 2-5%
Wolfram varbide 1-5%
Optimum implementation of the present invention is to contain by its weight percent meter:
Diamond 4.5%, cobalt 53%, copper 17.5%, nickel 5%, iron 5%, tin 5%, chromium 2.6%, zinc 2.4%, wolfram varbide 5%, wherein copper can be selected red copper for use.
A kind of new high-abrasive material that the present invention system obtains through repetition test according to prior art has adopted new component and new proportioning in its prescription, forms through high-pressure sinter.Diamond powder and other play the metal of keying action or the powder of metallic compound can be bonded together more securely, difficult drop-off in the use, thus can increase its work-ing life.The diamond grinding block of more existing same model is compared, and the present invention can improve processing work efficiency 1-1.5 doubly.The present invention can be suitable for grinding multiple mechanically resistant material, as granite, terrazzo, marble etc., and can improve the working accuracy of product, uses product processed of the present invention, and its smooth finish can improve greatly.
Describe the present invention below in conjunction with embodiment.
Embodiment 1 present embodiment contains by its weight percent meter: diamond 4.5%, cobalt 53%, red copper 17.5%, nickel 5%, iron 5%, tin 5%, chromium 2.6%, zinc 2.4%, wolfram varbide 5%.
Is that the various powder weighings of 200-400 purpose are good and mix by said ratio with granularity, and equal portions dress mould is through the high-pressure sinter moulding.Present embodiment can be made into the arc abrading block of 24 * 10 * 10mm, and every heavy 39.4 grams can be used to grind multiple mechanically resistant material.Every can be used to grind 80-130m such as granite, marble
2, compare with the diamond grinding block of existing same model, under identical condition, per hour can grind 7-15m more
2
The composition of embodiment 2-4 sees the following form, and the model of its product, performance and result of use are with embodiment 1.
Claims (3)
1, a kind of diamond grinding block is characterized in that containing by its weight percent meter: diamond 3.5-6.5%, cobalt 30-60%, copper 8-40%, nickel 5-46%, iron 1-6%, tin 1-6%, chromium 1-3%, zinc 2-5%, wolfram varbide 1-5%.
2, the described diamond grinding block of claim 1 is characterized in that containing by its weight percent meter: diamond 4.5%, cobalt 53%, copper 17.5%, nickel 5%, iron 5%, tin 5%, chromium 2.6%, zinc 2.4%, wolfram varbide 5%.
