Abstract
The invention discloses a magnetic grinding liquid for magnetic passivation of a cutting edge of a cutter and a preparation method of the magnetic grinding liquid. The magnetic grinding liquid is prepared by mixing components in parts by mass as follows: 18-22 parts of an oil-based dimethicone base solution, 3-6 parts of a zwitterionic surfactant and 0.2-0.4 parts of dodecylnaphthalene. The magnetic grinding liquid is required by a liquid magnetic passivation technology, the cutting edge passivated by the magnetic grinding liquid is fine and smooth compared with the cutting edge passivated in a dry manner, and roughness of other parts of the cutting edge is lower than that of the cutting edge passivated in a dry manner.
Description
Technical field
Magnetic mill liquid that the present invention relates to the passivation of a kind of cutting edge roundness magnetic force and preparation method thereof, belongs to cutting tool dulling technical field.
Background technology
At present, the existing cutting edge roundness passivating technique commercially mainly passivation of mechanical dry type abrasive material and the passivation of dry type magnetic, namely cutter is under mechanical clamping, does rotation and the turnover motion of certain track, reach the passivation to cutter in abrasive material formula.Difference because of abrasive material formula can realize corresponding different passivation effect.But this kind of mode is because all abrasive action occurring to cutting edge roundness and tool bodies, it is consistent that degree removed by material, and cause the polishing effect of the tool bodies when the large grinding capacity of abrasive grain is large to reduce, roughness is high, and cutting edge is crossed blunt and not round and smooth.Abrasive grain hour increases the bad assurance passivation effect of passivation time, and another technology dry type magnetic passivation need use the passivation of manipulator single-piece single-piece, passivation efficiency is low, equipment cost is high, therefore liquid magnetic force passivation is developed, magnetic mill liquid will be used when the passivation of cutter magnetic force, wherein the stability of size to magnetic mill liquid of the magnetic particle of magnetic mill liquid is most important, considerable influence is produced to passivation effect, the size of magnetic particle affects by following several factor, 1: in magnetic particle, adjacent two magnetic particles can form opposite pole, between the magnetic pole produced, attraction to particle is polymerized change greatly gradually, 2: the contact of different size rule particle, because the interaction between dipole produces van der waals force, make particle aggregation, 3, Action of Gravity Field makes particle precipitate, 4: static magnetic field active force.
Summary of the invention
The object of the invention is to solve the magnetic mill liquid that liquid magnetic force passivating technique uses, there is provided a kind of and make the liquid formulation that simply can realize magnetic force deactivation function, by by magnetic, abrasive material and surfactant are incorporated in base fluid, ion pair is passed through in surfactant one end, the effect such as Van der Waals for and hydrogen bond magnetic particle surface is formed and combines, produce agent film, prevent particle encounter from reuniting, other end agent is in base fluid, lyophily end is spread in the liquid phase, and its electrostatic interaction and sterically hindered effect make magnetic liquid and abrasive material form stable state, under the acting in conjunction of circumference gradient magnetic and the force of periphery, make magnetic according to certain nonrandom coalescence, form raised band, and the drive abrasive material motion that moves in a circle makes it to be mixed into a kind of cutting edge roundness magnetic force passivation magnetic mill liquid with ductile grinding medium and preparation method thereof.
A kind of cutting edge roundness magnetic force passivation magnetic mill liquid, this magnetic mill liquid is calculated according to the mass fraction, comprises oil base base fluid dimethicone 18 ~ 22 parts, is mixed by zwitterionic surfactant 3 ~ 6 parts and dodecyl naphthalene 0.2 ~ 0.4 part.
Described zwitterionic surfactant is lecithin.
A preparation method for cutting edge roundness magnetic force passivation magnetic mill liquid, this preparation method is carried out according to the following steps:
1) configuration of liquid part: first dimethicone and lecithin 8:2 ratio mixing by weight, be then added to dodecyl naphthalene, mix, lecithin and dodecyl naphthalene by weight ratio are 15:1;
2) then add 150 ~ 300 object Fe3O4 magnetics, the volume ratio of Fe3O4 magnetic and lecithin is 1 ~ 1.5:1;
3) allotment ratio is that 4 ~ 10um green silicon carbide of 7:3 adds above mixture with 2 ~ 6um single-crystal diamond lapping liquid and mixes by solid portion configuration: calculate by weight.
Owing to have employed technique scheme, the present invention has made the magnetic mill liquid required for a kind of liquid magnetic force passivating technique, utilize the cutting edge after the passivation of magnetic mill liquid meticulous compared with dry type passivation round and smooth, and cutting edge all the other positions outer is low compared with the roughness of dry type passivation.
