In terms of consumption and environmental pollution preferably than conventional abrasive material production, so, the production and application for expanding Cubic Boron Nitride Abrasives are machines
Tool application is the inexorable trend of development of machinery industry.
Cubic boron nitride honing disk is fixed in fine grinding bearing face, piston ring, washer, shim, compressor components, vane pump
Son, rotor, vane end faces, semiconductor material, magnetic material, cutter, precision spring etc. have a wide range of applications.It is general at present
There are resinoid bond, metallic bond and vitrified bond all over the cubic boron nitride mill bonding agent used.Resinoid bond mill
Disk quality is softer, and when processing cannot bear biggish stress, Grain Falling Off easily occurs, low efficiency, the service life is short, noise is big etc. asks
Topic；Metallic bond mill has the characteristics that thermal conductivity is good, bond strength is high, long service life, but because its self-sharpening is poor, is easy
The disadvantages of skidding, limits it in the application in high-speed grinding field；And ceramic binder cubic boron nitride mill preparation process requirement
Sintering temperature it is higher, therefore cubic boron nitride thermal damage is larger, significantly reduces the grinding intensity of mill.Hot pressing sintering method
The drawback one for preparing the history that metal binder cubic boron nitride mill has had more than 50 years, but being exposed in actual production
Directly fail to be fully solved, cubic boron nitride holding intensity is low, cubic boron nitride is easy to fall off, the difficult sword etc. out of abrasive material, greatly limits
Hot pressing sintering method prepares the scope of application of cubic boron nitride mill.Above-mentioned drawback is primarily due to the covalent of cubic boron nitride
Bond structure is difficult to form stronger chemical bonding with metallic bond, so it is easy to fall off to will lead to cubic boron nitride abrasive grain, in turn
Influence the processing quality and service life of mill.Therefore the holding power of metallic bond cubic boron nitride abrasive grain becomes limitation mill
The main factor of disk service life and processing quality.In order to solve this problem, strong carbon can be added in some metallic bonds
Compound formation element tungsten makes to form chemistry key connection between cubic boron nitride and bonding agent, can effectively improve cubic boron nitride
Holding power, but the fusing point of tungsten is higher, in sintering process can cubic boron nitride cause serious thermal damage.Therefore, it develops
A kind of cubic boron nitride has a higher holding power, while the small metallic bond mill of cubic boron nitride thermal damage is compeled in eyebrow
Eyelash, it will the processing performance of cubic boron nitride mill is greatly improved.
