Abstract
The invention discloses a kind of wear-resisting grinding wheel and its processing methods, specifically includes the following steps: (1) weighs raw material according to parts by weight: 100-120 parts of abrasive material, 10-14 parts of diamond, 1-3 parts of dextrin, 14-16 parts of bonding agent, 4-6 parts of wetting agent；(2) all raw materials are sieved；(3) mixed-powder is put into molding die housing-case mould, strikes off raw material with strike-off stick after vibration；(4) pressing plate is slowly put into cover die, is pressurizeed；(5) in hardening oven curing；(6) it tests to grinding wheel, is packed after qualified after processing is completed.Grinding wheel is processed through the invention, is sieved first to grinding wheel raw material, can prevent from being mixed into impurity in raw material, by being press-formed after carrying out shake to grinding wheel, so that the interior tissue of grinding wheel is more evenly, the hardness of grinding wheel is further improved, and processing method is simple, it is high-efficient.
Description
Technical field
The present invention relates to a kind of processing methods of grinding wheel, and in particular to a kind of wear-resisting grinding wheel and its processing method.
Background technique
Grinding wheel is the main tool that machinery production carries out work pieces process, is widely used in corase grinding, snagging, cutting and freely grinds
It cuts, has the characteristics that simple production process, process-cycle are short.But it is existing production grinding wheel technology there are grinding wheel wearabilities not
Ideal be easy to cause grinding wheel to deform, and wheel life is short, to affect the production of mechanical workpieces.
Summary of the invention
The present invention specifically comprises the following steps: to solve the above problems, provide a kind of wear-resisting grinding wheel and its processing method
(1) raw material is weighed according to parts by weight: 100-120 parts of abrasive material, 10-14 parts of diamond, 1-3 parts of dextrin, bonding agent 14-
16 parts, 4-6 parts of wetting agent；
(2) all raw materials are sieved；
(3) mixed-powder is put into molding die housing-case mould, strikes off raw material with strike-off stick after vibration；
(4) pressing plate is slowly put into cover die, is pressurizeed；
(5) in hardening oven curing；
(6) it tests to grinding wheel, is packed after qualified after processing is completed.
Further, in step (1), the abrasive material is Brown Alundum, white fused alumina, single alundum, black silicon carbide, green silicon carbide
One or more of.
Further, in step (1), the bonding agent is vitrified bond, resinoid bond, appointing in gum cement
It anticipates one kind.
Further, in step (1), the wetting agent is sulphur, sodium disulfide, graphite, copper or based on stearic acid
Compound.
Further, in step (4), pressure is forced into 200-210KG pressure, keeps 20-25s.
Further, in step (5), firm time 32-36h.
The beneficial effects of the present invention are: being processed through the invention to grinding wheel, it is sieved first to grinding wheel raw material, it can
To prevent from being mixed into impurity in raw material, by being press-formed after carrying out shake to grinding wheel, so that the interior tissue of grinding wheel is more evenly, into
One step improves the hardness of grinding wheel, and processing method is simple, high-efficient.
