Description
Technical field
The invention belongs to cutting liquid field, more particularly to a kind of Super-high Thickness cutting liquid and preparation method thereof.
Background technology
Wire-cut Electrical Discharge Machining is by the use of mobile fine wire (copper wire or molybdenum filament) as tool-electrode, while work
Tool electrode connects the negative pole of high frequency pulse power supply, and workpiece connects the positive pole of high frequency pulse power supply.When pulse voltage is added between the two poles of the earth,
Just under prevailing condition at relatively a certain gap minimum or dielectric strength lowest part punctures medium, and produce spark in the part and put
Electricity, so as to produce instantaneous high-temperature (up to 10000 DEG C or so), workpiece localized metallic material is quickly reached fusing point, boiling point until
Gasification, so that cutting forming.
According to the difference of cutting material thickness, Wire-cut Electrical Discharge Machining can be divided into general thickness cutting (H≤300mm),
Big thickness cutting (300mm ＜ H ＜ 500mm) and Super-high Thickness cutting (H >=500mm).In Super-high Thickness cutting, the frequency of fracture of wire
Rate is also higher, and its principal contradiction is, because joint-cutting is smaller, and the thickness of workpiece is higher, working solution joint-cutting more difficult to get access, together
When, the scrap produced after cutting in joint-cutting is difficult to exclude, and causes joint-cutting to block so that the state of processing is affected, also, useless
Bits are discharged not in time, then easily attach on wire electrode, make wire electrode partial short-circuit, and then easily cause fracture of wire.
The content of the invention
It is an object of the invention to provide a kind of Super-high Thickness cutting liquid for being difficult to cause fracture of wire, another object of the present invention
It is the preparation method that this cutting liquid is provided.
To achieve these goals, the present invention provides a kind of cutting liquid of Super-high Thickness cutting, by the original of following parts by weight
Material composition：50-60 parts of triethanolamine, 8-12 parts of alkaline aqueous solution, Fe (OH)310-15 parts of colloid, 3-5 parts of brightener, aqueous rust preventive

The ability of Super-high Thickness workpiece, also provides good alkaline environment for rust remover.Fe(OH)3Colloid can reduce wire electrode well
Oscillation Amplitude, it is ensured that cutting accuracy.The main function of brightener, which shows to remove by active surface, rests on metal watch
Greasy dirt, oxidation and the unoxidized surface impurity in face, keep cleaning, glossiness and the color fastness outside object.Aqueous rust preventive can be
Metal surface forms hydrophobic film, there is good anti-rust action to workpiece.Burster possesses the explosion energy of superelevation, is conducive to
The increase and chip removal of explosion energy in electro-discharge machining, alkaline-resisting defoamer, then for eliminating the foam produced in cutting.
Further, alkaline aqueous solution is sodium hydroxide or potassium hydroxide solution, and sodium hydroxide and potassium hydroxide are easy
Obtain, it is cheap.
Further, burster is acrylic acid modified rosin, acrylic acid modified rosin diethylene glycol (DEG) ester, maleic rosin modified propylene
At least one of acid resin, dihydro rosin or tetrahydrogenated rosin.Above-mentioned burster is for common rosin, and explosive effect is more
It is good, so that cutting effect becomes apparent from.
