Description

A kind of manufacture method of combined binder CBN paster emery wheels
Technical field
The present invention relates to a kind of manufacture method of combined binder CBN paster emery wheels.
Background technology
With the development of mechanical processing industry, hardness, the intensity of material are also constantly improving, to process technology it is also proposed that Very high requirement, CNB (cubic boron) are a kind of abrasive materials that hardness is only second to diamond, have high wearability with it is hard Degree, is the best abrasive material of current machining of special steel, and our companies develop combined binder CBN paster emery wheels, suitable for super The Surface Machining of hard material, solves following problem(1)Improve the grinding precision of product;(2)It is multiple compared with pure vitrified bond Closing bonding agent has more preferable sharp ability(3)Due to splicing after burning till by several times, firing period shortens, and improves yield rate.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of combined binder CBN paster emery wheels, to big specification shape Complicated CBN emery wheels carry out paster processing, reduce the complexity of technique, improve yield rate.
To achieve these goals, the technical scheme is that designing a kind of system of combined binder CBN paster emery wheels Make method, it is characterised in that comprise the following steps:
Step 1: preparing bonding agent, bonding agent each component is put into bonding agent mixing tank, is well mixed, sieving;The combination Agent is prefabricated powder, and its main chemical compositions is Na2O 8-12%, K2O 8-15%, B2O3 25-30%, Al2O3 15-22%, MgO 3-5%, CaO 0.5-2%, SiO2 16-23%, HBT are 720 DEG C;
Step 2: batch mixing, CBN abrasive materials are well mixed with the bonding agent and heat reactive resin prepared in advance, sieving, it is made into Moulding mixture;The CBN abrasive materials, bonding agent, the quality proportioning of heat reactive resin are 3:1:1
Step 3: preparing mould, the upper releasing agent of mould spraying, molding mass is put into after weighing by several times, is struck off after stirring evenly;
Step 4: covering die cap, press is started, sends the emery wheel and mould that have spread out under pressure head and carries out hot pressing, and is incubated 15 points Clock.After the completion of cooling, depanning;
Step 5: loading of kiln, is checked emery wheel, confirm flawless carry out loading of kiln, emery wheel is separated with carborundum, is put into resistance to In fiery crock, load in kiln;
Step 6: burning till, 100 DEG C are directly warming up to, is then warming up to 600 DEG C from 100 DEG C with 28 DEG C/h programming rate, afterwards 660 DEG C are warming up to from 500 DEG C with 25 DEG C/h programming rate, is incubated 3 hours, after the completion of, carry out Temperature fall;
Step 7: when grinding wheel is cooled to room temperature, kiln discharge;
Step 8: configuration resin glue to grinding wheel carry out strike-through, during overturn several times, drying;
Solidify Step 9: grinding wheel is put into curing oven;
Step 10: geometry processing is carried out to grinding wheel;
Step 11: the grinding wheel processed is bonded with matrix.
The advantages of the present invention are:The present invention uses combined binder technology, comprehensive utilization ceramics and tree Two kinds of performances of fat bonding agent, while grinding wheel shape holding capacity is ensured, farthest improve the self-sharpening energy of emery wheel.
