The desired character of metal adhesive emery wheel that is used for glass grinding relates to many-side, comprise cutting good (when being grinding burn or the generation frequency of grinding fracture little, the working (machining) efficiency height), the long-life, non-corrosives etc. are out of shape little high strength (bending strength is contour) etc. when having pressurization.The metal adhesive emery wheel that has fully satisfied these requirements is desirable emery wheel.
But,, as following mentioning, can not fully satisfy these requirements for described metal adhesive emery wheel in the past.
For Cu-Sn is metal adhesive, if the Cu composition is many, then cutting is poor, if the Sn composition is many, then cutting improves, but the reduction of the intensity of binding agent, the consequently lost of life.The binding agent of Cu-Sn system generally is short-life as a result.Fe-Cu-Sn is a metal adhesive, and along with the increase of the addition of Fe, Cu-Sn prolongs in the life-span of metal adhesive emery wheel, but when carrying out common wet type grinding in glass grinding, after the grinding easily at the binding agent of the emery wheel rust of looking unfamiliar.If there is the rust composition in the binding agent face, it is transferred to and is ground on the material then to begin the back in next grinding, produces dirtyly, and this problem is pointed out always.Co-Cu-Sn is the metal adhesive non-corrosive, but along with the increase of the addition of Co, becomes hard binding agent usually, produces the disadvantage that cutting reduces.
To this, Ni-Cu-Sn is a metal adhesive owing to use Ni, and bonding is strengthened, thereby prolongs the life-span of emery wheel.From this viewpoint, preferably set the Ni amount higher.
In addition, in order to make metal adhesive emery wheel hard and that the life-span is long, must be able to create highdensity extrusion forming body.
But, along with the amount of Ni is set highly, then require high sintering (firing) temperature, be in the manufacturing of metal adhesive emery wheel therefore at Ni-Cu-Sn, generally be to use not produce the carbon system sintering mould that adds thermal deformation.Become under the situation that does not increase production cost in the restriction aspect this autofrettage, obstruction hard and the metal adhesive emery wheel that the life-span is long is provided.
Promptly, at Ni-Cu-Sn is in the manufacturing process of metal adhesive emery wheel, in order to obtain highdensity pressure sintering body, then the abrasion of carbon die are remarkable to apply high pressure, need the mould that frequently more renew, so production cost increase, on the other hand, have the upper limit owing to be fit to high-pressure sinter and the little sintering temperature that heat-resisting alloy or heat-resisting steels allowed of mould exchange frequency, therefore have to employed Ni amount is limited, exist opposite requirement.
In the Production Example that the present inventor studied, if the Ni composition is lower than 40wt%, then can't obtain the effect of improving of wheel life, on the contrary,, then generally need the sintering temperature more than 800 ℃ if the Ni composition is more than the 40wt%.
The present invention proposes in order to address the above problem etc., and its purpose is to provide cutting good, and is hard and the life-span is long, and rust produces, and do not have during pressurization and be out of shape and the high Ni-Cu-Sn of intensity is metal adhesive emery wheel and manufacture method thereof.
In addition, the present invention also aims to be provided at diamond lap particle in the metal adhesive of above-mentioned composition and/or CBN abrasive grains well in conjunction with and the Ni-Cu-Sn that keeps be metal adhesive emery wheel and manufacture method thereof.

In metal adhesive is formed, contain the Sn element of 19～30wt% scope.In Cu-Sn system, the Sn element has the effect that helps the binding agent fusion.If lack than 19wt%, then sintering temperature too raises, and can't effectively produce.If, because intensity reduction, the then lost of life of emery wheel more than 30wt%.The preferred especially 19～25wt% of the amount of Sn element.
Use Ag will give resulting metal adhesive good rerum natura in the present invention.That is, has the sintering facilitation effect.
And then, the use of Ag, if Ag is added in the metal of Cu-Sn system, low temperature liquid layer scope increases during owing to its fusion, even therefore its addition is less, the fusing point of binding agent also can reduce.Therefore, needed the Ni-Cu-Sn above 800 ℃ of high temperature sinterings is metal adhesive in the past, can use than its low temperature its sintering.Promptly, at Ni-Cu-Sn is in the manufacturing of metal adhesive emery wheel, because the use of Ag makes 650～850 ℃ sintering condition become possibility, therefore can in such lower temperature range, use and have the heat-resisting alloy of durability or the mould of heat-resisting steels, when sintering, give high pressure, so just the metal adhesive emery wheel can be manufactured highdensity sintered body.And, even since the mould of heat-resisting alloy or heat-resisting steels add high pressure also need not be continually mold exchange more, therefore can not cause cost to rise, can provide hard as mentioned above and the life-span is long, good metal binding agent emery wheel.
In order to obtain above-mentioned effect, in metal adhesive was formed, the amount of essential Ag was the scope of 1～7wt%.If lack than 1wt%, then can't obtain above-mentioned fusing point and reduce, if surpass 7wt%, then find the tendency of silver-colored segregation, even and above 7wt%, the sintering facilitation effect that Ag produced is also little.The amount of Ag is 2～5wt% more preferably.
The Cu element constitutes the remainder that above-mentioned metal adhesive is formed.The amount of this Cu is at least 5wt%, and the total weight of preferred Ni and Cu is more than the 60wt%.
