Description
Technical field
The present invention relates to abrasive techniques fields, particularly belong to a kind of CBN grinding wheel formula.
Background technique
Grinding wheel is most important one kind grinding tool in grinding.Grinding wheel is that bonding agent is added in abrasive material, through green compact, drying
With roasting and manufactured porous body.Grinding wheel is one kind that dosage is maximum in grinding tool, using face is most wide, high speed rotation when use, can
The outer circle of metal or non-metal workpiece, inner circle, plane and various type faces etc. are roughly ground, half refine and fine grinding and fluting and
Cutting etc..Substance in grinding wheel to bonded abrasive claims bonding agent, the performance of bonding agent determine the intensity of grinding wheel, impact resistance,
Heat resistance and resistance to corrosion.Bonding agent is broadly divided into ceramics, resin, rubber and four kinds of metal at present, wherein resinoid bond
Intensity is high, elasticity is big, impact resistance, is suitable for v>The high-speed grinding of 50m/s, can be made into disc wheel, for slot grinding, cutting etc..
The grinding wheel for using resin as bonding agent is referred to as resin wheel.Resin wheel divide by abrasive material be generally divided into ordinary resin grinding wheel and
Superhard resin wheel.It is the sand being mainly ground to point that ordinary resin grinding wheel, which is with conventional abrasive materials such as white fused alumina, Brown Alundum, silicon carbide,
Wheel, it is the grinding wheel being mainly ground to point that superhard resin wheel, which is with diamond or CBN,.Resin wheel is small with grinding force, is ground
The advantages that temperature is low, self-sharpening is good, grinding efficiency is high, is widely used in the hard brittle materials such as hard alloy, ceramics, glass
Grinding in.It is known that the ratio that CBN abrasive material participates in ablation in resin wheel up to now only has about 10%,
Most of CBN abrasive material because power in connection is poor, in grinding process be heated, or by external force influenced and it is premature fall off,
To largely constrain service efficiency and the service life of resin wheel.
Summary of the invention
The object of the present invention is to provide a kind of CBN grinding wheel formulas, overcome the deficiencies in the prior art, using CBN abrasive material,

A kind of CBN grinding wheel is made in white fused alumina fine powder, thin comminuted steel shot, lithium carbonate, zinc oxide, has high intensity, wear-resisting, high temperature resistant has simultaneously
There is waterproof long service life.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of CBN grinding wheel formula, is made from the following raw materials in parts by weight：40-70 parts of CBN abrasive material, 20-40 parts of white fused alumina abrasive material,
8-15 parts of black silicon carbide powder, 4-8 parts of liquid phenolic resin, 2-4 parts of n-BMA, is received 10-25 parts of epoxy powder
8-12 parts of off-white marble dust, 5-10 parts of white fused alumina fine powder, comminuted steel shot 4-8 parts thin, 2-4 parts of lithium carbonate, 2-4 parts of zinc oxide.
Further, it is made from the following raw materials in parts by weight：45 parts of CBN abrasive material, 30 parts of white fused alumina abrasive material, black silicon carbide powder 9
Part, 10 parts of epoxy powder, 6 parts of liquid phenolic resin, 2.5 parts of n-BMA, 9 parts of Nano dolomite powder, Bai Gang
7 parts of beautiful fine powder, 6 parts of thin comminuted steel shot, 3 parts of lithium carbonate, 2.5 parts of zinc oxide.
Further, the white fused alumina granularity is F160-F220.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of CBN grinding wheel formula of the present invention, using CBN abrasive material, white fused alumina abrasive material, black silicon carbide powder, epoxy powder,
Liquid phenolic resin, n-BMA, Nano dolomite powder, white fused alumina fine powder, thin comminuted steel shot, lithium carbonate, zinc oxide are made
A kind of CBN grinding wheel improves the wetability between grinding wheel raw material, flexural strength by adding lithium carbonate, and refractoriness significantly improves,
Addition black silicon carbide effectively improves the corrosion resistance of resin wheel, wearability, while in conjunction with aluminium oxide, significantly improving grinding wheel
High-temperature behavior, epoxy resin liquid and phenol-formaldehyde resin powder have excellent waterproofness, and epoxy resin liquid can reduce the deformation journey of grinding wheel
Degree is added white fused alumina powder and greatly improves wear-resisting property, prolongs the service life, social benefit is obvious.
