In case of using coolant on high-speed machines, the spindle of which rotates with a frequency of more than 2000 rpm, it may additionally contain an antifoam in the amount of 0.005-0.1 wt.%.

The presence of stagnant areas in shop coolant wiring systems increases the likelihood of microbiological damage to HIV. In order to protect microbiological damage, bactericides such as furacilin, formalin, vazin and others can be added to the composition of the coolant in an amount of 0.005 to OD wt.

Component content, May.

The coolant is prepared by simply diluting all the ingredients in water.

During testing, the wear resistance of the coolant was measured in drilling operations with a diameter of 4.8 mm in steel 40X and 12X 18NYuT using drills made of high-speed steel Р6 М5 as a cutting tool. The coefficient of tool life (Kt) is taken as the ratio of the drill time from the proposed coolant (before its wear is h 0.6 mm, taken as a blunt criterion) to the drill run time up to h 0.5 mm from the reference coolant.

Anti-corrosion properties are investigated according to GOST 6243-75, pH of solutions is according to GOST 624.3-75.

Formulations coolant and the results of the test of the research Institute are presented in table. 1 and 2.

Note. The listed ingredients are water, making the total weight up to 100 May. % Prototype Note .. When using foci of corrosion, when using KaiK SPECIFIC, the presence of an HMO additive with high surface activity provides high wetting and lubricating properties of the coolant, which is also characterized by stability during storage and good operation and good anti-corrosion properties. The test results showed that the proposed liquid allows an increase of 10

Table 2 of the known coolant lubricated - they are not. The resistance of the cutting tool when machining steel 40X is 2.2 times, when machining corrosion-resistant steel 1.3 times compared with the use of known coolant. In addition, the increase in the service life of the coolant in 2 times. The proposed water coolant can be used in all areas of industry related to the machining of parts made of alloyed structural and corrosion-resistant steels with a blade and abrasive tool. An oil-cooling fluid for machining of metals based on water, triethanolamine and sodium nitrite, characterized in that, in order to improve antiwear and anti-corrosion properties, the liquid additionally contains the sodium salt of maleic acid ester and substituted oligoxyethylenes at the following ratio of components, wt.%: Triethanolamine 0.3-0.5 Sodium nitrite. 0.3-0.5 Sodium salt of maleic acid acid ester and substituted oligooxy ethylenes B0, 5-2 Water Remaining Sources of information Taken into account during the examination: 1.
