Abstract
The invention provides a microporous grain flow polishing liquid and a preparation method thereof. The polishing liquid is prepared from the following raw materials in parts by weight: 10-15 parts of grains, 42-60 parts of silicon oil, 42-60 parts of triethanolamine and 6-10 parts of silica gel. The preparation method comprises the step of evenly stirring the grains, silicon oil, triethanolamine and silica gel which are taken in the formula at a vacuum state so as to obtain the grain flow polishing liquid product, namely, adding the grains with different particle sizes in a soft grinding material medium for mixing and blending. The prepared grinding material has no precipitation phenomenon, good flowability and stability, high surface material removing rate and extremely low scratching and particle residue, and the larger the concentration is, the better the viscoelasticity is, thus the microporous grain flow polishing liquid is widely applied to the technical field of precision machining on the surface of a microporous runner of a work piece.
Description
Technical field
The present invention is a kind of abrasive Flow polishing fluid, and particularly a kind of micro-holes abrasive Flow polishing fluid and preparation method thereof utilizes this polishing fluid that specific component is polished and can obtain nano level surface accuracy.
Background technology
The abrasive Flow Machining technology is the soft abrasive medium that is loaded with the viscoelastic body of abrasive material by a kind of, and reversingcurrent is realized polishing through the part machined surface under pressure.Utilize the abrasive particle in the abrasive Flow to use countless cutting tools as, workpiece surface is cut repeatedly, thereby reach certain precision work purpose with its hard sharp corner angle.Any position that abrasive Flow is flowed through all will be by polishing, and for the inner cavity of component that those general purpose tools are difficult to contact, the superiority of abrasive Flow Machining technology is particularly outstanding.When abrasive particle evenly and progressively adds man-hour to water passage surface or corner, produce deburring, polishing, chamfering effect, the abrasive Flow Machining technology is specially adapted to the precision work of micro-holes.
Polishing fluid is the key factor that influences micro-holes water passage surface working accuracy.Abrasive material in the abrasive Flow polishing fluid under pressure with the workpiece surface effect, directly have influence on the removal speed of workpiece surface material.
Some companies of the U.S., adopt big particle diameter abrasive material to strengthen mechanical effect in the polishing process as companies such as EXTRUDE HONE, CABOT, and then the raising polishing efficiency, but this method also produce simultaneously surface tear, polishing fluid mobile poor, be easy to defective such as precipitation.
Summary of the invention
The invention provides a kind of micro-holes abrasive Flow polishing fluid, when having solved existing polishing fluid processing work polishing fluid mobile poor, scratch shortcoming such as workpiece surface easily.
The invention also discloses the preparation method of above-mentioned micro-holes abrasive Flow polishing fluid, technology is simple, satisfies environmental requirement.
Micro-holes abrasive Flow polishing fluid of the present invention,It is characterized in that by following raw materials by weight portion than making:
10 ~ 15 parts of abrasive particles, 42 ~ 60 parts of silicone oil, 42 ~ 60 parts of trolamines, 6 ~ 10 parts in silica gel.
Abrasive particle of the present invention is selected from white fused alumina, silicon carbide, norbide or artificial diamond's stone flour, and the grain size number of abrasive particle is between F400#-F2000#.
The preparation method of abrasive Flow polishing fluid of the present invention may further comprise the steps:
Abrasive particle, silicone oil, trolamine, silica gel are got material by above-mentioned prescription to stir under vacuum state and promptly obtains abrasive Flow polishing fluid product.
Performance index of the present invention are:
Is the silicon-carbide particle of F2000 for the aperture for the 0.1mm aperture has adopted grain size number.In the abrasive material process for preparation, with silicone oil (characteristic of dimethyl silicone oil mainly contains: physiology inertia, nonpoisonous and tasteless, range of viscosities is wider, chemical stability is good, zero pour is lower, can life-time service in 50 ~ 150 ℃ temperature range) and trolamine (
, trolamine have water absorbability, can be miscible with water, ethanol, acetone etc., simultaneously trolamine also is good solvent.Solubleness at benzene in the time of 25 ℃ is 4.2%.Because trolamine is a macromolecular substance, when stirring with silicone oil, can play the effect of thickening, thereby silicon-carbide particle can be suspended in the carrier of abrasive material), during according to the allotment of the volume ratio of 1:1, silica gel in addition, the abrasive material that makes does not have deposited phenomenon to be taken place, and concentration is big more, and visco-elasticity is good more; PH-value is about PH7.4 through measurement, is tending towards neutral.
In the abrasive material process for preparation, the abrasive material of adjustable macrobead high density carries out attrition process at the relatively large test specimen in aperture.In the abrasive material process for preparation, the abrasive material of adjustable small-particle lower concentration carries out attrition process at the less relatively test specimen in aperture.
Below experimental results show that the positively effect of product of the present invention:
Before the processing, the aperture initial surface roughness 1.86 that obtains by detection
(Fig. 1), at abrasive concentration 20%, granularity F2000#, under the situation that process period, 30Min determined, adopting pressure to be respectively the Ra value that 4.2MPa, 6.1MPa, 7.9MPa obtain is 0.56
, 0.44
, 0.35
, see Fig. 2, Fig. 3, Fig. 4 respectively.Show that by these data under finite concentration, granularity and process period situation, pressure is big more, the abrasive Flow flow velocity is high more, acts on that power increases on the tube wall, and the surfaceness that obtains is low more, and polishing effect is good more.
Abrasive grain be F2000#, pressure 4.2MPa and process period 30min situation under, adopt the abrasive material processing of 20%, 30%, 40% concentration, the surperficial Ra value that obtains is respectively 0.56
, 0.52
, 0.46
, Fig. 5, Fig. 6, detected result shown in Figure 7.By comparing, it is big more to draw concentration, and the surface roughness value after the polishing is low more, illustrates under certain condition, and the abrasive particle quantity that participates in simultaneously grinding increases, and the polishing number of times increases, and is good more to the reduction effect of surfaceness.If but the concentration of polishing fluid is excessive, certainly will cause abrasive Flow polishing fluid thickness, less than the 0.1mm micro-holes, excessive concentration pressure is excessive, can influence the dimensional precision of micropore for diameter.In test, the polishing fluid concentration of this research preparation is lower than 40%.
Positively effect of the present invention is:The abrasive particle mixing back modulation of adding different-grain diameter with soft abrasive medium forms; the abrasive material that makes does not have deposited phenomenon to be taken place; flowability and stability are all good; and concentration is big more; visco-elasticity is good more; have high surfacing clearance and extremely low scuffing and particle residue, can be widely used in the precision processing technique field of workpiece aperture water passage surface.
