Description
Technical field
The present invention relates to the water-based milling liquid that a kind of online electrolytic dressing grinding is used, belong to the grinding fluid technology that mechanical precision grinding machining is used.
Background technology
Online electrolytic dressing (Electrolytic In-process Dressing is called for short ELID) grinding technique just has been subjected to paying attention to and application in accurate and ultraprecise manufacture field with its significant advantage from the eighties appearance in last century.ELID grinding system essentially consist comprises: ELID special purpose grinder, metal matrix micro mist emery wheel, high frequency pulse power supply and ELID electrolysis special grinding fluid.Raising along with mechanical processing technique and electronic technology, grinding machine, emery wheel and the power supply of present stage production can be good at satisfying the requirement of ELID technology, and because the ELID technology to the particular requirement of grinding fluid, makes the technology of the special-purpose grinding fluid of ELID become the bottleneck of ELID technical development.
ELID grinding technique principle is: grinding process medium cast iron base grinding wheel is as anode, make negative electrode with truing electrode, in the gap of emery wheel outer round surface and electrode by the special-purpose grinding fluid of electrolysis ability is arranged, at the effect lower grinding wheel anode metal matrix of pulsed electrical energy constantly by electrolysis, and the abrasive particle in the emery wheel can not sustain damage, thereby plays the effect of emery wheel dressing.Yet online electrolysis is a kind of sex change dressing, promptly at the emery wheel metallic matrix by the electrolytic while, the electrochemical action by grinding fluid forms the passive film that can hold a large amount of abrasive particles that one deck has certain elasticity, certain thickness, certain intensity at wheel face.What play material removal effect in the ELID grinding process is the abrasive particle that is dipped in the passive film, so the thickness of passive film, compactness and sticking power all have a significant impact its grinding quality and working (machining) efficiency.Passive film also will have formation speed faster in addition, remedies the requirement that passive film consumes thereby can satisfy in grinding process, to reach a dynamic balance state.The character of the generative process of wheel face passive film and generation passive film all depends on the performance of the special-purpose grinding fluid of ELID to a great extent.
The article of the special-purpose grinding fluid of research ELID seldom, abroad have than proven technique, but because its technical know-how was not all delivered, the mechanism of domestic research ELID grinding has all carried out corresponding research to its electrolytic grinding liquid basically, wherein Harbin Institute of Technology's research early, the relevant series product of oneself have been arranged now, comprised coventional type, HDMY-10, HDMY-20 etc.Other research institutions have: Changchun Institute of Optics and Fine Mechanics, Beijing University of Technology, Hunan University, Dalian University of Technology etc.
Present stage, commercially available online electrolytic grinding liquid was difficult to control in the passivation film thickness of wheel face generation, can not well satisfy the requirement of ELID grinding under the different condition, and the passive film insulating power of generation is relatively poor, makes wheel life reduce.All contain NaNO in most of grinding fluids
2Or chromate ion, along with to the improving constantly of environmental protection requirement, these grinding fluids will be no longer suitable.
Summary of the invention
The water-based milling liquid that the object of the present invention is to provide a kind of online electrolytic dressing grinding to use, this grinding fluid is environmentally friendly, and preparation cost is low, and use properties is good.
The present invention is realized that by the following technical programs the water-based milling liquid that a kind of online electrolytic dressing grinding is used is characterized in that, contains following component and mass percentage content thereof in quality is 100 parts water:
Sodium orthomolybdate: 0.2～0.6%; Yellow soda ash: 0.1～0.5%; Water glass: 0.3～0.8%; Borax: 0.1～0.4%; Sodium Benzoate: 0.2～1.2%; Sodium-chlor: 0.01～0.1%; And to contain volume percent with water be 0.7～1.2% boric acid ester.
Advantage of the present invention: the water-based milling liquid that provides has overcome in this grinding fluid of present stage and has contained Sodium Nitrite, and objectionable constituent such as chromate ion do not contain easy pollution and harmful material, can satisfy the environmental characteristics requirement; Can satisfy ELID grinding requirement under the various conditions, the thickness of the passive film that generates is adjustable in 10～120 mu m ranges, it is adjustable in 20～50min scope that the emery wheel dressing reaches balance time, and the passive film strong adhesion that generates, electrical insulating property good (equalizing current generally remains in the scope of 0.4～1.0A) has compactness and certain elasticity preferably; Its compound method is simple, and cost is low, and rust-preventing characteristic, cooling property and lubricity are good, and SOLUTION PROPERTIES is stable.
