Special-purpose water-base cutting liquid for cannonball cartridge finish turning and producing method thereof

Abstract

The invention discloses water-based cutting fluid special for fine turning cannonball cartridges and a production method, wherein, the water-based cutting fluid special for the fine turning cannonball cartridges can maximally decrease the cutting temperature and the cutting force, improve the efficiency of cutting machining, assure the cutting accuracy and the surface quality of the workpiece, prolong the service life of the cutting tool, decrease the cost, and meet the requirement of environmental protection. The raw materials of the special water-based cutting fluid and the weight percentage are as follows: phytic acid 1.5-2.5 percent, sodium benzoate 7-9 percent, trolamine 5-7 percent, trisodium phosphate 1.5-2.5 percent, sodium thiosulfate 0.5-1.5 percent, benzotriazole 0.05-0.15 percent, industrial alcohol 2.5-3.5 percent, polyethyleneglycol 3.5-4.5 percent, glycerin 2.5-3.5 percent, isothiazolone 0.4- 0.6 percent, and deionized water 68-72 percent. The production method is that: the synthetic condition of normal temperature, middle temperature and normal temperature is adopted for stirring synthesis.

Description

Technical field: [0001] The invention relates to a cutting fluid for metal cutting, especially a cutting fluid that can reduce the cutting temperature and cutting force to the greatest extent, improve the cutting efficiency, ensure the cutting accuracy and surface quality of the workpiece, prolong the service life of the tool, and reduce the cost. 1. A special water-based cutting fluid for fine-turning of shells and cartridges that meets environmental protection requirements and its production method. Background technique: [0002] Metal cutting processing is the process of cutting metal blanks through tools under the condition of power provided by machine tools to obtain shape, size, precision and surface quality that meet the requirements. It can be divided into turning, milling, drilling, planing, and boring. , Hinging, drawing and grinding etc. During the cutting process, the chips act on the rake face of the tool with a pressure of up to 2-3GPa, and at the same time, t...

AI Technical Summary

Problems solved by technology

Since H62 is a copper-zinc alloy of 60% copper and 40% zinc, while H68 is a copper-zinc alloy of 70% copper and 30% zinc, during cutting, a large amount of cutting heat generated in the cutting area can easily cause copper-zinc alloy workpieces Partial burns on the surface, resulting in welding and fusion, directly affect the surface processing quality of the workpiece; and because zinc is an amphoteric metal, it will be corroded in the air environment of acidic medium and alkaline medium, and the corrosion resistance of copper to acidic medium is also very poor

Therefore, the existing cutting fluid cannot meet the special requirements of the cutting process of the shell cartridge, so that the following problems often occur during the cutting process:

[0006] 3. The rust resistance of the surface of the workpiece after cutting is very poor. Due to the oxidation and discoloration, uneven spots on the surface are formed, which brings great difficulties to the subsequent chemical polishing and the formation of chromium-free passivation film.
