Background technology
Line cutting working liquid generally has good cooling, lubricated, cleaning and antirust function, also has other property: have certain dielectric strength, go to dissociate, arc extinguishing, prevent fracture of wire and long service life, safety non-toxic etc.Therefore select suitable wire cutting liquid can obtain desirable processing smooth finish and working (machining) efficiency, and can extend the work-ing life of lathe, the machinofacture that is chosen in of working fluid adds and seems particularly important man-hour.
Universal line cutting working liquid is all to take oiliness as basestocks in the market, separately adds some basic emulsifying agents, cooling with this working fluid when realizing processing.It has following defect:
(1) because oleaginousness is larger, environmental pollution is more serious.And Working environment, workman self keep a public place clean poor, make machine tool washing difficulty;
(2) processing performance is poor, and when cutting copper aluminium and alloy thereof, cutting efficiency is low;
(3) cutting speed in feet per minute and cutting efficiency are low, and tooling cost is increased;
(4) oily cutting liquid is volatile, is difficult for preserving;
Summary of the invention
In view of the foregoing, be necessary to provide a kind of cutting efficiency line cutting working liquid high, more environmental protection.
The present invention realizes like this, a kind of environmental protection water aqua type wire cutting working solution, wherein, the weight percent content of each component is as follows: the first rust-preventive agent 5%~10%, the second rust-preventive agent 5%~10%, lubricant 10%~15%, non-ferrous metal sanitas 0.1%, purification agent 2%~3%, couplant 0.5%, emulsifying agent 6%~10%, water quality stabilizer 5%~6%, weak base agent 3%~5%, Central European CE110 18%~20%, static inhibitor 2%~5%, defoamer 1%, sterilant 1%~2%, surplus is pure water.
Concrete, described the first rust-preventive agent and the second rust-preventive agent are respectively sebacic acid, sad.
Concrete, described lubricant is propanediol polyoxypropylene Soxylat A 25-7.
Concrete, described non-ferrous metal sanitas is 124 Triazole.
Concrete, described emulsifying agent is OP-10.
Concrete, described couplant is butyl glycol ether.
Concrete, described defoamer is dimethyl silicone oil.
Concrete, described weak base agent is sodium carbonate.
Concrete, described water quality stabilizer is polyacrylamide.
Concrete, described static inhibitor is silicone emulsion.
Environmental protection water aqua type wire cutting working solution of the present invention, tool has the following advantages: first, in working fluid, containing oily component, environment protection clean, easily lathe is cleaned; Secondly, good cutting effect, improves 20%~30% than traditional cutting working liquid cutting efficiency; Again, when cutting copper, aluminium and alloy thereof, because its toughness is lower, therefore excellent cutting performance.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in more detail
An environmental protection water aqua type wire cutting working solution, for the cooling and lubrication to wire cutting machine work.Its component mainly comprises the first rust-preventive agent, the second rust-preventive agent, lubricant, non-ferrous metal anticorrosive agent, purification agent, couplant, emulsifying agent, water quality stabilizer, weak base agent, static inhibitor, defoamer, sterilant, additive, Central European CE110, pure water.
The rust-preventing characteristic of considering water-based line cutting working liquid, rust-preventive agent selects bad meeting to cause processing work and the corrosion of wire cutting machine tool guide rail, and processed surface smoothness is poor, and working fluid flavescence, has oxidation corrosion phenomena.
Preferably, non-ferrous metal sanitas is 124 Triazole, and it is mainly anticorrosion to copper aluminium etc.
Emulsifying agent is selected OP-10, and couplant selects alcohols as Virahol, and alkaline agent is selected mineral alkali or other weak base, in case the impact on lathe paint, but guarantee that sterilization effect must maintain ph value more than 8.
Central European CE110 is that Central European company manufactures and research and development, and it can be bought at Central European company production and sales point and website, is mainly additive, for plurality of raw materials synthetics, in working fluid, play and reduce silk damage, play lubricated, osmosis, can accelerate chip removal speed, improves machined surface surface smoothness.
Concrete, the first mix proportion scheme: sebacic acid 5%, sad 5%, propanediol polyoxypropylene Soxylat A 25-7 (2040) 10%, 124 Triazole 0.1%, ethanol 2%, butyl glycol ether 0.5%, emulsifier op-10 6%, polyacrylamide 5%, sodium carbonate 3%, Central European CE110 18%, silicone emulsion 2%, dimethyl silicone oil 1%, sterilant BK 1%, pure water 41.4%.
Concrete, the second mix proportion scheme: sebacic acid 10%, sad 10%, propanediol polyoxypropylene Soxylat A 25-7 (2040) 15%, has 124 Triazole 0.1%, ethanol 3%, butyl glycol ether 0.5%, emulsifier op-10 10%, polyacrylamide 6%, sodium carbonate 5%, Central European CE110 20%, silicone emulsion 5%, dimethyl silicone oil 1%, sterilant BK 2%, pure water 12.4%.
Concrete, the third mix proportion scheme: sebacic acid 8%, sad 8%, propanediol polyoxypropylene Soxylat A 25-7 (2040) 12%, has 124 Triazole 0.1%, ethanol 3%, butyl glycol ether 0.5%, emulsifier op-10 8%, polyacrylamide 6%, sodium carbonate 4%, Central European CE110 19%, silicone emulsion 4%, dimethyl silicone oil 1%, sterilant BK 2%, pure water 24.4%.
Its technique is as follows: by said ratio raw material and water and amine alkali building-up reactions, and temperature 120 degree, constant temperature 5 hours, with instrument testing, without floating oil viscous liquid, cool to 80 degree and add successively constant temperature sampling in 2 hours by raw material, after detection specific conductivity, select salable product discharging.
With above-mentioned discharging, be used in middle wire cutting machine, multitool cutting, parameter: the first cutter: pulsewidth 32us, between arteries and veins: 1: 4, electric current: 3~3.5A.The second cutter: pulsewidth 12us, between arteries and veins: 1: 7, electric current: 1.8A.The 3rd cutter: pulsewidth 2us, between arteries and veins: 1: 9, electric current: 0.5A.Four blade: pulsewidth 1us, between arteries and veins: 1: 9, electric current: 0.2A.Working (machining) efficiency improves 23.2%, and working accuracy is brought up to 0.001um, and waist drum deviation narrows down to 0.0001um.
The working fluid that said ratio is good is pressed to 1: 20 proportioning, impeller monolithic cutting processing in turbine driven set, fast wire winding DK7740 is used, and cutting efficiency improves 25%
The above is the preferred implementation of invention, it should be pointed out that for those skilled in the art, under the premise of not departing from the present invention, can also make some improvement and retouching, and these improve with retouching also should be considered as protection scope of the present invention.
