What is the polishing technology of the special-shaped mould?
Extrusion honing: also known as the abrasive flow processing, the process method is to use a semisolid abrasive abrasive, under the effect of extrusion honing machine, make the abrasive surface of processed spares reciprocating motion, the parts of all kinds of mould, cross aperture and edge grinding and polishing, a new technology of fillet deburring.
Extrusion honing abrasive with different particle size, viscosity, under the influence of extrusion, select the appropriate process parameters, can make parts surface coarse degree of the hammer on the basis of the original surface roughness by honing 3 ~ 5 min increase 2 ~ 3 grade, can control the precision at micron level.
Extrusion honing can not only grind and polish the parts surface, but also grind and polish the mold cavity surface of extrusion die, drawing die and cold stamping die.
The application range is as follows.
1.It honing and polishing the complex cavity surface of various raw material die, drawing die, extrusion die and injection mold.
2.It is used for honing and polishing of concealed cross holes, special-shaped holes, step holes and all kinds of parts with more complicated inner shapes.
3.It can remove the surface hardening layer and micro defects after edm or laser machining.
4.It can honing and polishing copper, aluminum, hardened steel, ceramic, hard alloy and non-metal parts.
5.The machine can be widely used in medicine, aviation, metallurgy, manufacturing, electronics, textile and other fields.
