20 ~ 10 parts of ZA10#;
40 ~ 10 parts of CA12#;
10 ~ 19 parts of phenol-formaldehyde resin powders;
2 ~ 6 parts of phenolic resins wetting agents;
0.1 ~ 1 part of silane coupler;
1 ~ 5 part, glass fibre;
3 ~ 7 parts of copper powders;
Described ZA is fused alumina zirconia, and CA is ceramic microcrystalline abrasive material, and C is black silicon carbide, and the model of silane coupler is KH-550.
C100# of the present invention, ZA8# etc. have definite implication in the industry, refer to material, the granularity of abrasive material.
A processing method for ceramic microcrystalline abrasive material heavy load high speed grinding wheel, is characterized in that processing method is as follows:
1) mixing material: 22 ~ 25 DEG C of temperature, first abrasive material is put into agitated kettle in the batch mixing of relative humidity 60%, then the phenolic resins wetting agent of title is added, start agitator, mix; In abrasive material and the mixing of phenolic resins wetting agent, another adverse current batch mixing pot mixes load weighted resin-oatmeal and filler.Then material mixed first batch mixing pot is poured into second pot, continue to mix, until mix.Taking capacity as the adverse current batch mixer of 100 kilograms is as example, the incorporation time of abrasive material and wetting agent is 5 minutes, and resin-oatmeal, filler incorporation time are 15 minutes, and two mixed material of adverse current batch mixing pot are formed into moulding mixture for 10 minutes by mixing again;
2) moulding: 22 ~ 25 DEG C of temperature, the Nei Jiang center, assembly room of relative humidity 60% strengthens part and grinding is used the molding mass of part to sieve, according to the requirement of production line list, weighing molding mass, evenly spreads out in the grinding wheel die of rotation and strikes off rear compacting;
3) sclerosis: after emery wheel depanning sclerosis oven curing.
When emery wheel making of the present invention, the molding mass that center is strengthened to part and grinding use part is respectively by accurately weighing of formula, mix and sieve with adverse current batch mixer respectively, according to the requirement of production line list, weigh molding mass, evenly spread out in the grinding wheel die of rotation and strike off, mould is moved into the compacting of compacting center, after the depanning of emery wheel blank, be placed on sclerosis backing plate, in hardening furnace, harden by certain hardening curve.
It is high that the present invention has operating rate, and grinding force is large, the expensive low advantage of grinding efficiency.Centered by dividing emery wheel, the present invention strengthens part and grinding use part, two parts adopt different formulas, the formula that center strengthens part has advantages of that intensity is high, good with abrasive material glass fibre caking property, do not use fused alumina zirconia, ceramic microcrystalline abrasive material and the relative higher material of other prices because center strengthens part, thereby provide cost savings.Grinding is used part by adding fused alumina zirconia, ceramic microcrystalline abrasive material, copper powder, glass fibre etc., and optimizes proportioning separately, has strengthened grinding and has used grinding efficiency partly.When the present invention suppresses, adopt 300 ~ 5000T hydraulic press, can process diameter 455 ~ 900mm, the ceramic microcrystalline abrasive material resin heavy load high speed grinding wheel of thickness 40 ~ 110mm.The quality index of the shape of emery wheel of the present invention, size, technical conditions is carried out JB/T 3631 professional standards.
