Compared with the traditional preparation technology, the preparation technology has the advantages that: metal components in the bonding agent can be effectively protected from being oxidized in reducing atmosphere sintering, and the performance of the CBN abrasive particles is protected from being affected at a high temperature. Compared with air atmosphere sintering, the preparation technology has the advantages that: the service life of the grinding wheel is prolonged by about 15 percent, the grinding wheel has good self-sharpening property, and the effect of a machined product is obviously improved.
Description
Technical field
The present invention relates to the preparation technology of a kind of cermet binder diamond/CBN emery wheel, belong to the fabricating technology field of superhard material goods.
Background technology
Cermet binder diamond/CBN emery wheel mainly should have a extensive future in the processing of metal material, and market capacity is huge.Compare with common corundum wheel, cermet binder diamond/CBN emery wheel processing metallic has many advantages: increase service life about 100 times, waste water and dregs reduces to 1/100; Can reduce the replacing number of times and the time of emery wheel, practice thrift the finishing time of emery wheel, working (machining) efficiency can significantly improve; Emery wheel expands little, is difficult for burn, controls the workpiece machining accuracy easily; Do not need finishing, workpiece processing back better effects if or the like.
Advantages such as metal and pottery are mixed and made into bond, possess good toughness, and the emery wheel self-sharpening is good.The cermet binding agent sand wheel adopts usually and carries out pressure less high temperature after the cold moudling and bury the sand method and carry out sintering.Existing sintering method is because sintering time is long, and metal is easy to oxidation takes place when sintering, loses its due effect.Therefore, be necessary further improvement.
Summary of the invention
The object of the invention aims to provide the preparation technology of a kind of cermet binder diamond/CBN emery wheel, improves the service life and the self-sharpening of this emery wheel, to overcome weak point of the prior art.
Press the preparation technology of a kind of cermet binder diamond/CBN emery wheel of this purpose design, it is characterized in that adopting reducing atmosphere stove sintering metal ceramic bond diamond/CBN emery wheel, may further comprise the steps:
1) will cold pressing after the said emery wheel that finishes buries sand, be placed in the reducing atmosphere stove;
2) guarantee that oven door sealing is good, air inlet and the path of giving vent to anger is unobstructed and can make the reducing gas convection current be full of whole body of heater;
3) set heating curve, with beginning to heat up after the air atmosphere eliminating fully;
4) said emery wheel cools off with stove.
The placement of this emery wheel is buried sand thickness and is no more than 10mm apart from wheel face in said 1 step; Need the gap of 2-10mm between each layer emery wheel, to guarantee the circulation of reducing atmosphere; Reducing atmosphere is best with hydrogen.
Heating curve adopts staged in said 3 steps: from room temperature to 300 ℃, heating rate is 2～3 ℃/min; At 300 ℃ of insulation 1～1.5h; Be warming up to 750 ℃ from 300 ℃, heating rate is 1.5～2 ℃/min; At 750 ℃ of insulation 1.5～2h; Be warming up to 900 ℃ from 750 ℃, heating rate is 1～1.5 ℃/min; At 900 ℃ of insulation 1～1.5h; Cool off with stove again.
Said grinding wheel formula and weight ratio are: CBN abrasive material (100/120) 60%, cermet bond 30%, wetting agent and binding agent 5%, auxiliary material (SIC or Al
2O
3) 5%, raw material is mixed, then cold moudling.
Conventional preparation process relatively is suitable for the sintered ceramic binding agent sand wheel.The present invention adopts reducing atmosphere sintering metal ceramic bond diamond/CBN emery wheel, and agglomerating plant is than traditional preparation process technology (air atmosphere sintering) somewhat more complicated.Compare with traditional preparation process technology, adopt the reducing atmosphere sintering can effectively protect the metal ingredient in the bond not oxidized, protection CBN abrasive particle at high temperature performance is not affected, and can make ceramic component that changes of microstructure takes place under reducing atmosphere again.Find also that through field experiment compare with traditional preparation process technology, the cermet binding agent sand wheel of sintering possesses better self-sharpening under the protection of reducing atmosphere, improves service life about 15%, the effect of converted products is significantly improved.
Cermet binder diamond of the present invention/preparation technology is simple for the CBN emery wheel, in common reducing atmosphere stove, can realize.Cermet binder diamond/CBN emery wheel through gas-protecting sintering is a kind of new product of on the basis of ceramic CBN emery wheel, developing, and the research of bond and the research of sintering processing are the key points of this new technology.The present invention has significantly promoted cermet bond CBN performance of products from sintering technology.
