Description
Technical field:
The present invention relates to grinding tool and grinding technique field, particularly a kind of CBN emery wheel and preparation technology thereof of low-temp ceramics wedding agent.
Background technology:
We recognize that the CBN abrasive material is a kind of superhard material, and it plays main ablation as abrasive material in emery wheel, and the quality of abrasive material directly influences a lot of performance index of emery wheel.But main in the emery wheel structure is its weave construction, is wedding agent.The effect of wedding agent is to disperse, control the CBN abrasive material.The CBN emery wheel in past is because its insufficient strength, and abrasive material comes off easily, the grinding wheel shape that is hard to keep, and easily cause the obstruction of emery wheel.In addition, general ceramic sintering temperature is more than 1200 ℃, because the anti-burning temperature of CBN abrasive material self is 1000 ℃, though the theoretical heat resisting temperature of CBN abrasive material is 1000 ℃, the CBN abrasive material just produces micro-oxidation since 700 ℃, easily causes scaling loss.
Summary of the invention
For overcoming the defective that exists in the prior art, the invention provides a kind of CBN emery wheel and preparation technology thereof of low-temp ceramics wedding agent, reduce the firing temperature of ceramic bond, improve CBN emery wheel and the preparation technology thereof of wedding agent the low-temp ceramics wedding agent of the wettability of abrasive material, wedding agent hardness, wear resistance etc.
For reaching above goal of the invention, the technical scheme that the present invention takes is: a kind of CBN emery wheel CBN emery wheel of low-temp ceramics wedding agent is made of wedding agent, auxiliary material, mill layer, transition layer.The composition of wedding agent and ratio are: SiO
248～60%, Al
2O
325～37%, Na
2O 5～10%, Li
2O 3～7%; The batching of abrasive material and ratio: CBN 23～40%, SiC 23～40%; Wedding agent 20.3～29.8%, dextrine powder 0.1～0.3%, walnut powder 0.1～0.2%; The batching of transition layer and ratio: SiC 64～76%, wedding agent 21.9～32.9%, dextrine powder 0.1～0.2%.
Selecting for use of abrasive material, can adopt the abrasive material of unlike material, different varieties to mix use, as can in described CBN emery wheel, adding a certain proportion of diamond.
The preparation technology of the CBN emery wheel of low-temp ceramics wedding agent, through mixing material, the compression moulding of abrasive material blank, abrasive material blank sintering, matrix viscose glue size real join determine and processing, abrasive material with matrix is bonding, turning trial, abrasive material cylindrical and end face finishing, the inspection of emery wheel abrasive material, transient equilibrium, outward appearance processing, final inspection.Mixed CBN abrasive material and SiC transition layer molding mass according to the weighing of moulding substance, are dropped into moulding in the grinding tool respectively sequentially.Wherein compression moulding characteristics are: with the moulding of pressure forming machine compacting emery wheel blank, adopt the voltage limiting mode control pressure in claimed range, to reach the density of control product abrasive material; With overcoat and core bar the special grinding apparatus of certain taper is arranged all, the unrelieved stress when reducing the blank mould unloading; Adopt the method for layering compacting, solve the pressure conduction and freely do not reach the even problem of density unevenness.Wherein the firing process characteristics are: the temperature curve control mode is adopted in burning till of ceramic CBN emery wheel; The sintering temperature of CBN mill, the sintering temperature of pottery all are controlled at below 1000 ℃; Adopt the roasting mode of protection of inert gas, make the CBN abrasive material not oxidized under hot conditions.
The invention has the beneficial effects as follows: by reducing the firing temperature of ceramic bond, saved the CBN abrasive material and just produced micro-oxidation since 700 ℃, easily caused the problem of scaling loss.The wedding agent firing temperature is low, makes the intensity height, and is good to the abrasive material wettability, control the ability height.Because selecting for use at abrasive material, the unlike material that adopts, the abrasive material of different varieties mix the mode of using, for example in the CBN emery wheel, add a certain proportion of diamond, improved the intensity of product, can improve the grinding tool part defective in use of using single abrasive material, play the effect that improves grinding.
