The content of the invention
Present invention aim to address existing heavy load high speed grinding wheel is because reconditioning pressure is little, grinding efficiency is low, reconditioning matter
The defect of amount difference, there is provided a kind of operating rate is high, the ceramic microcrystalline abrasive material heavy load high speed sand that grinding force is big, grinding efficiency is high
Wheel and its processing method.
The present invention is achieved through the following technical solutions：
I.e. a kind of ceramic microcrystalline abrasive material heavy load high speed grinding wheel, including center strengthening part and grinding use part, it is special
Levy and be
The parts by weight of each raw material of the center strengthening part are：
100 parts of C100#；
15 ~ 28 parts of phenol-formaldehyde resin powder；
5 ~ 10 parts of phenolic resin wetting agent；
0.1 ~ 1 part of silane coupler；
1 ~ 5 part of glass fibre；
2 ~ 6 parts of copper powder；
The grinding is using the parts by weight of each raw material in part：
40 ~ 80 parts of ZA8#；
20 ~ 10 parts of ZA10#；
40 ~ 10 parts of CA12#；
10 ~ 19 parts of phenol-formaldehyde resin powder；
2 ~ 6 parts of phenolic resin wetting agent；
0.1 ~ 1 part of silane coupler；
1 ~ 5 part of glass fibre；
3 ~ 7 parts of copper powder；
The ZA is fused alumina zirconia, and CA is ceramic microcrystalline abrasive material, and C is black silicon carbide, model KH-550 of silane coupler.
C100#, ZA8# of the present invention etc. have in this industry the implication for determining, that is, refer to material, the granularity of abrasive material.
A kind of processing method of ceramic microcrystalline abrasive material heavy load high speed grinding wheel, it is characterised in that processing method is as follows：
1）Mixing material：In 22 ~ 25 DEG C of temperature, the batch mixing of relative humidity 60% is interior to be first put into agitated kettle by abrasive material, then will claim
Number phenolic resin wetting agent add, start agitator, mix；It is another while abrasive material and phenolic resin wetting agent mix
Adverse current batch mixing pot is well mixed load weighted resin-oatmeal and filler.Then first mixed material of batch mixing pot is poured into second
Individual pot, continues to mix, until being well mixed.By taking the adverse current batch mixer that capacity is 100 kilograms as an example, the mixing of abrasive material and wetting agent
Time is 5 minutes, and resin-oatmeal, filler incorporation time are 15 minutes, and two mixed material of adverse current batch mixing pot pass through again mixing 10
Minute forms molding mass；
2）Shaping：In 22 ~ 25 DEG C of temperature, the assembly room Nei Jiang centers strengthening part of relative humidity 60% and grinding are used
Partial molding mass sieves, and is required according to production line list, weighs molding mass, uniformly spreads out in the grinding wheel die of rotation and strikes off
After suppress；
3）Hardening：In hardening oven curing after emery wheel depanning.
During emery wheel making of the present invention, by center strengthening part and grinding using the molding mass of part respectively by formula
Precise, is well mixed with adverse current batch mixer sieves respectively, according to production line list require, weigh molding mass, uniformly spread out into
In the grinding wheel die of rotation and strike off, mould is moved into into the compacting of compacting center, be placed on after emery wheel blank depanning on hardening backing plate,
Harden by certain hardening curve in hardening furnace.
The present invention has operating rate high, and grinding force is big, the advantage that grinding efficiency high cost is low.The present invention divides on emery wheel
Centered on strengthening part and grinding use part, two parts to adopt different formulas, the formula of center strengthening part that there is intensity
The good advantage of high and abrasive material glass fibre caking property, due to center strengthening part do not use fused alumina zirconia, ceramic microcrystalline abrasive material and its
The of a relatively high material of his price, so as to save cost.Grinding is using part by adding fused alumina zirconia, ceramic microcrystalline abrasive material, copper
Powder, glass fibre etc., and optimize respective proportioning, enhance the grinding efficiency that grinding uses part.Adopt during present invention compacting
With 300 ~ 5000T hydraulic presses, 455 ~ 900mm of diameter, the ceramic microcrystalline abrasive resin heavy load of 40 ~ 110mm of thickness can be processed
High speed grinding wheel.The shape of emery wheel of the present invention, size, the quality index of technical conditions perform the professional standards of JB/T 3631.
