Description
Technical field
The present invention relates to sintered diamond tool manufacturing technology field, in particular to a kind of alusil alloy bonding agent diamond
Grinding wheel and its manufacturing method.
Background technique
Skive is the ideal tools for being ground hard brittle material and hard alloy as a kind of super-hard abrasive tool, is grinding
Important component part in system, in grinding, it is desirable that skive grinding efficiency with higher and grinding quality,
I.e. high in machining efficiency, machining accuracy is high, lower wear resistance ratio and higher service life.The skive being commonly used
Bonding agent has resinoid bond, metallic bond and vitrified bond.Resin bond wheel quality is softer, and when processing cannot hold
By biggish stress；Metal bonded wheel has the characteristics that thermal conductivity is good, bond strength is high, long service life, but certainly because of it
Sharp property is poor, is easy to limit it in the application in high-speed grinding field the disadvantages of skidding；And prepared by Technique of Vitrified Diamond Wheels
The sintering temperature for crossing range request is higher, therefore larger to diamond thermal damage, significantly reduces the grinding intensity of grinding wheel.Hot pressing is burnt
Connection prepares the history that metal anchoring agent diamond wheel has had more than 50 years, but the drawback one exposed in actual production
Directly fail to be fully solved, to diamond hold intensity is low, diamond is easy to fall off, abrasive material it is difficult go out sword etc., strongly limit hot pressing burning
Connection prepares the scope of application of skive.Above-mentioned drawback is primarily due to the covalent bond structure of diamond, is difficult and metal
Bonding agent forms stronger chemical bonding, so will lead to, diamond abrasive grain is easy to fall off, so influence grinding wheel processing quality and
Service life.Therefore metallic bond becomes limitation grinding wheel service life and processing quality most to the holding power of diamond abrasive grain
Principal element.In order to solve this problem, carbide tungsten can be added in some metallic bonds, make diamond with
Chemistry key connection is formed between bonding agent, can effectively improve the holding power of diamond, but the fusing point of tungsten is higher, sintering process
In serious thermal damage can be caused to diamond.Therefore, a kind of pair of diamond is developed with higher holding power, while to diamond
The small metal bonded wheel of thermal damage is extremely urgent, it will the processing performance of skive is greatly improved.
Summary of the invention
Present invention aims at existing technical problem is solved, provide a kind of alusil alloy bonding agent skive and
Its manufacturing method.Using, it can be achieved that low-temperature sintering, reducing diamond the characteristics of alusil alloy matrix phase low melting point and eutectic point
Damage.And in bonding agent activity Ti element addition, diamond can be soaked well, and form fine and close carbide, pole
The earth improves bonding agent to the holding power of diamond abrasive grain, and the two improves the wear-resisting property of mill jointly, increases Buddha's warrior attendant stone mill
The service life of disk.By adding Si element, the mechanical strength of acieral can be effectively improved, while Si is also to be carbonized by force
Object formation element is able to suppress reacting for Al and diamond, moreover it is possible to reduce fusing point.By adding active element Ce, Ge, Neng Gouxian
Write the antioxygenic property for improving alloy.
