Description
Technical field
The present invention relates to cutter polishing fields, and in particular to a kind of carbide-base ceramics abrasive pastes and its preparation side
Method.
Background technique
Tool lapping cream in the prior art is divided into oily molten abrasive pastes and water-soluble abrasive pastes two major classes.Wherein, the molten class of oil is ground
Grinding cream has wetability good, the advantage that polishing force is small, polishing heat is low, is mainly used for processing highly polished hard alloy contour hard
The part of alloy material, instrument and meter, measurer, cutlery, grinding tool etc., but the polishing velocity of such abrasive pastes is slow, and is not easy clear
It washes；Water-soluble abrasive pastes viscosity is small, Yi Paixiao, high in machining efficiency, is mainly used for processing and slightly corrodes metal, wiring board, glass, pottery
The hard brittle materias product such as porcelain, jewel, agate, although having the advantages that polishing velocity is fast, buffed surface is not smooth enough,
It is easy to cause scratch to polished part surface.Common abrasive pastes mainly have corundum class, silicon carbide and boron carbide class, oxidation chromium class,
The different types of abrasive pastes such as diamond class.With the continuous development in modern each field, the demand of abrasive pastes is also to be increasingly enhanced,
Abrasive pastes have wear-resisting durable economic benefits, but current grinding effect not yet develops to ideal state, surface roughness
Technical requirements are not achieved, polishing velocity is slow, yield rate is low.Existing abrasive pastes micro mist dispersing characteristic is poor, main grinding-material it is micro-
Sight geometric shape is undesirable, and the size range of grinding-material particle is wide, and component lubrication property is bad, so that material is being ground
It is undesirable to grind surface of polished quality, is extremely difficult to quality requirement, the product qualification rate being ground is low.It most of abrasive pastes and grinds
Although grinding fluid can enhance grinding effect, cutter easy to damage when in use.Belong to liquid form additionally, due to lapping liquid, is easy to make
At waste is used, to increase production cost；And existing abrasive pastes cannot all be bonded with matrix well, and abrasive pastes is caused to exist
It is fallen off during grinding and polishing, reduces the utilization rate of abrasive pastes.
