Description

A kind of preparation method of neodymium iron boron later stage machining cutting fluid

Technical field

The present invention relates to magneticsubstance Machining Technology for Cutting field, particularly relate to a kind of preparation method of neodymium iron boron later stage machining cutting fluid.

Background technology

Along with the raising of cutting technology, the kind of cutting fluid gets more and more.Oil base cutting fluid and the large class of water-base cutting fluid two substantially can be divided into by its type.

Oil base cutting fluid many employings mineral oil, fatty oil, mixing oil and extreme pressure oil is raw material, and general oilness is good, but cooling performance is poor.Be used in the courses of processing such as high speed and heavy cut, worsen bad border health because smoldering tempestuously, even having the danger causing fire.Due to splashing and the pollution also exacerbated environment of being scattered of oil, simultaneously for preventing deterioration by oxidation, improve its lubrication extreme pressure property, often need to add the organism extreme pressure agent of chloride, sulphur, phosphorus, oiliness improver, rust-preventive agent and oxidation inhibitor etc.These additives are the influential organic compound of HUMAN HEALTH, are used by the restriction of the developed countries and regions such as the U.S., Europe.

Water-base cutting fluid have good cooling results, can save energy and the feature such as to increase work efficiency, be day by day widely used in metal working process, and have the trend progressively substituting oil lubricant.Wherein especially more outstanding with the superiority of complete synthesis type water-base cutting fluid.Compare with microemulsion (also known as semi-synthetic liquid) containing mineral oil emulsion liquid (emulsification oil type) with traditional, high water base Totally synthesized cutting fluid is not owing to containing machinery oil completely, in cleaning, rust-preventing characteristic, cooling, processing visuality, germ resistance and stability etc., all there is outstanding feature, thus obtain gradually and apply widely.

Mainly comprise the techniques such as section, abrasive disc, punching in sintered NdFeB post-treatment, the cutting fluid with good lubrication, antirust and cooling performance in its post-treatment, must be used.Neodymium iron boron product is because product itself is containing rare earth element, and chemical property is active, powder metallurgical body has between space, different metal and easily forms galvanic interaction etc., and product is oxidizable, perishable, and general water-base cutting fluid is difficult to the requirement meeting its processing completely.From existing patent, document and technology, existing cutting fluid mainly can be applicable to the processing such as the metals such as iron, aluminium, copper are cut, mill, and the water-base cutting fluid Product Report for sintered NdFeB post-treatment is few, even if there is a small amount of report, also there is such-and-such defect, use needs can not be met.Therefore, a kind of sintered NdFeB special-purpose water-based milling liquid is developed just imperative.

Summary of the invention

The object of the invention is to the preparation method proposing a kind of neodymium iron boron later stage machining cutting fluid, the cutting fluid adopting the method to prepare is different from the cutting fluid of prior art, can be suitable for the later stage machining of NdFeB material.

For reaching this object, the present invention by the following technical solutions:
