Technical field
The present invention relates to a kind of manufacture method of grinding tool, the ceramic bond super-hard of more particularly to a kind of low-porosity is ground
The manufacture method of tool.
Background technology
Grinding tool is a kind of instrument for being ground, grinding and polishing, and is largely made up of abrasive material addition bonding agent, stomata
It is to constitute one of three elements of grinding tool, the height of the porosity will directly affect the intensity, hardness and application of grinding tool.
For grinding tool, abrasion is mainly in Grinding Process, and bonding agent is destroyed and causes coming off for abrasive particle,
And hardness represents the complexity that abrasive particle comes off in the presence of external force from abrasive surface, that is, represent holding of the bonding agent to abrasive particle
Power, hardness is higher, and hold is bigger, and abrasive particle is more difficult to come off, and the life-span of grinding tool is higher, and the porosity is higher will cause bonding agent pair
The hold of abrasive particle is smaller.
All it is line contact type mill when to the surface grinding or arris grinding of ceramics or the fragile material such as stone material
Cut, chip removal and cooling effect are very good, completely can be using low-porosity even pore-free to the less demanding of the grinding tool porosity
Grinding tool, can so improve the hardness of grinding tool, so as to improve the service life of grinding tool, improve the cost performance of grinding tool, reduction mill
Has the consumption of raw material.
In to the processing grinding of the material of the toughness such as mild steel, because the toughness of material is big, very long chip, knot are easily produced
Mixture is easily destroyed or eliminated by chip, causes the inordinate wear of grinding tool, and chip is longer, and inordinate wear is more violent.In order to
The inordinate wear of grinding tool is reduced, the porosity of grinding tool should be reduced as much as possible, when chip pocket very little, chip and the new life of accumulation
Face is melted again, is waited less than Grain Falling Off, abrasive particle is over grinding.
Ceramic bond super-hard abrasive tool by vitrified bond and super hard abrasive it is repressed and sintering form, while having ceramics
The characteristics of bonding agent and super hard abrasive, compared with other grinding tools, its grinding capacity is strong, the shape of grinding tool when durability height, grinding
Shape retentivity is good, and the parts size precision processed is high, and self-sharpening can be good, and finishing interval time is long, and suitable for various cold
But liquid is cooled down.
The technique that the manufacture method of traditional ceramic bond super-hard abrasive tool is wet moulding, freely burnt till, its elder generation is in original
Temporary binders are added in material, blank block is suppressed with press after being well mixed, are dried, and are sent into sintering furnace, certain
Burnt till under sintering condition, ceramic bond super-hard abrasive tool, which is made, in this method has very macro porosity, generally 30% or so.
If the ceramic bond super-hard abrasive tool of low-porosity can be produced, ceramic bond super-hard abrasive tool is set to have simultaneously
The advantages of having intensity height, hardness height and long lifespan, and it is applicable to the grinding field to toughness material.
The content of the invention
The main object of the present invention is to provide a kind of method for the ceramic bond super-hard abrasive tool for manufacturing low-porosity.
In order to realize above-mentioned main purpose, the manufacture method for the ceramic bond super-hard abrasive tool that the present invention is provided includes raw material

Mould.
It is used to other raw materials be bonded in cold pressing step from the temporary binders in above scheme, raw material to be formed
Briquet, its amount only need to enable raw material cold moudling can；In cold pressing step, well mixed raw material is suppressed in cold stamping die
To the 70%-90% of design density, improve the density of briquet, it is easy to be molded, and most of air extrusion in briquet gone out into briquet,
Reduce the gas discharge amount in heat-press step, because the method being molded using constant volume is suppressed, so the only thickness of briquet
Direction size can be suppressed, and density is too big after cold pressing, and briquet expanded by heating can damage corresponding mould in heat-press step, therefore not
Can be too big；In drying steps, evaporating in briquet is allowed, follow-up hot pressing is easily carried out；In pre-sintering step, when
The temperature of briquet is heated to pre-sintering temperature, the low melting point composition in temporary binders and vitrified bond is thermally generated gas
