Description
Technical field
The present invention is a kind of metal working fluid, especially eco-friendly titanium alloy micro-emulsion cutting fluid.
Background technology
Along with the development of science and technology and the raising of living standards of the people, international community pays close attention to the strick precaution to potentially contaminated more, to the protection in uncontaminated field etc.Problem of environmental pollution has become one of common issue of countries in the world, and the problem of environmental pollution that is caused by lubricating oil more and more causes people's great attention.The friendly cutting fluid of development environment is protection of the environment, solves oil crisis and take full advantage of one of measure of sun power.Although titanium or titanium alloy has many good performances, its machinability is also poorer than austenitic stainless steel, and its relative machinability is 25～38% of No. 45 steel.Cutting ability and the cast nickel-base alloy of some titanium alloy are similar, therefore titanium or titanium alloy belongs to typical difficult-to-machine material.Generally, the tooling cost of titanium or titanium alloy is high more than starting material, and this has limited the widespread use of titanium alloy to a certain extent.
Metal working fluid is widely used in mechanical processing industry, has created huge economic benefit to the mankind, but simultaneously not only the health of human body is consisted of harm, but also environment is caused severe contamination, harm and pollute and mainly comprise the following aspects:
At first be to affect environment: the use of cutting fluid is the root that mechanical industry pollutes ecotope, the a large amount of smog, the oily foam that splashes and the cutting fluid of leakage that in making processing, produce, having a strong impact on green manufacturing and recycling economy, becoming that Sustainable development needs to be resolved hurrily and problem needing to overcome.According to incompletely statistics, the used cutting liquid annual emissions of domestic only mechanical workout is hundred million tons nearby.Mineral oil is the important component part of traditional cutting fluid, and poor because of its biological degradability, extended residual is in water and soil, so that lake, ocean, river and subterranean stream system are subject to pollution in various degree.In addition, also contain the environmentally harmful additives such as sulphur, phosphorus, chlorine in the cutting fluid.
Next is unhealthful: produce a large amount of smog, the oily foam that splashes because of cutting fluid in the machining, the capital impacts operator's health, chemical elements such as extreme-pressure additive institute sulfur-bearing, phosphorus, chlorine particularly, thus the xerosis cutis of making, breach, redness are brought out multiple dermatosis.There are some researches show, directly contact the operator of cutting fluid, suffer from respiratory system disease than directly contact or workman's ratio of never working at lathe are not much higher.Sodium Nitrite and hydramine cutting fluid additive commonly used easily reacted generation carcinogens nitrite in the past, and the internal organ such as the liver of its surrogate p t butylbenzoic acid salt pair animal, kidney are harmful.
To affect cost at last: along with improving constantly of emission standard, use traditional cutting fluid machining component, indirectly increased the production cost of component, be unfavorable for very much improving the core competitiveness of enterprise.Studies show that according to Japan, German relevant expert: only use the expense of cutting fluid, just account for 7～17% of whole component manufacturing cost.
The characteristics such as titanium alloy material is little owing to its density, and specific tenacity is high, and is high temperature resistant, and antioxidant property is good are widely used.But the titanium alloy machining property is poor, affects being widely used of this material.Therefore in the processing titanium, add alloying element, become important measures of the intensity that improves titanium.
At present, had the dried cutting technology of environmentally safe, but be of limited application, within from now on considerable time, machinery manufacturing industry also must be used cutting fluid.The process velocity and the working (machining) efficiency that how to improve titanium or titanium alloy are problem demanding prompt solutions, and except from the aspect researchs such as cutter material and tool geometry angle, the research of eco-friendly metal working fluid is still a problem that can not be ignored.Therefore, under the prerequisite that does not affect the cutting fluid use properties, research and develop harmlessly, pollution-free or oligosaprobic environmental friendliness titanium alloy cutting liquid tool is of great significance.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cutting temperature and chemically reactive is low, deformation coefficient is little, cutting force is large, the sticking few eco-friendly titanium alloy micro-emulsion cutting fluid of cutter.
The present invention solves the problems of the technologies described above with following technical scheme:
