The grinding wheel has good cutting, and the service life is long, non-corrosive, deformation when pressurization it is small and have it is high-intensitive [green wood it is clear it, tea
Mountain reaches will metal cement grinding wheel .CN 1541808A [P] .2004.]；Zhao in 2013 builds woods and has invented a kind of cubic boron nitride
Product metallic bond and its production method, raw materials used and weight percent are as follows: SiO255-60%, Al2O310-15%,
K2O 6-8.5%, Na2O 2.5-5.5%, Cu 6-10%, glass putty 0.5-1.5% and zinc powder 0.3-1%.Invention refers to this combination
Agent has lower refractoriness and higher intensity, is sintered between 600-960 DEG C, suitable for preparing diamond and cube nitridation
Boron grinding tool, the operating speed of superhard material grinding tool can be made to reach 160m/s or more, and [Zhao builds woods CBN product metal bonding
Agent and its production method .CN103331703A [P] .2013.]；Marvin's in 2013 is superfine with cubic boron nitride, Cu-Sn-Ti alloy
Powder and graphite are that raw material is prepared for self-lubricating metal binder cubic boron nitride grinding wheel, and abrasive grain is evenly distributed in grinding wheel, abrasive grain
It reacts to form enhanced primary treatment with bonding agent, there are free state graphite inside grinding wheel, wheel strength meets processing request [Marvin's
Preparation process .CN 104690658A [P] .2015. of super a kind of self-lubricating metal bonding agent cBN grinding wheel of]；A.R. spy in 2016
Wei Bielski etc. has invented a kind of cubic boron nitride compact, which includes that (amount is at least for polycrystal cubic boron nitride particle
70vol.%) and metallic character bonding agent, and bonding agent has super heat-resistant quality.[AR Tversky, cubes of N bank
Boron nitride compact, cBNcompacts.CN 103451460B [P] .2016.].
For Cubic Boron Nitride Abrasives, traditional metallic bond is because there is very high interfaces with cubic boron nitride abrasive grain
Can and the caking property that both makes is poor, cubic boron nitride abrasive grain relies primarily on the mechanical aid power generated after matrix shrinkage and inlays
In carcass metal, it is hardly formed chemical bonding, cubic boron nitride particle during high-speed grinding is caused to be easy to take off with matrix
From greatly reducing grinding performance and the service life of Cubic Boron Nitride Abrasives.And bonding agent is because of the high temperature meeting that generates in grinding process
There is ruckbildung, causes the holding power of matrix cubic boron nitride abrasive grain inadequate, cause shear action to weaken, so as to cause mill
Cut the decline of quality.To solve the heat problem generated by grinding, during actual use through being carried out frequently with a large amount of coolant liquids
Lubrication, and the discharge of coolant liquid can cause environment centainly to pollute.
