Description

The invention relates to the manufacture of abrasive tools, and in particular to methods for their treatment to increase the durability of abrasive tools.

The purpose of the invention is to improve the performance properties of an abrasive tool during dry grinding by premagnetizing the impregnator solution.

The proposed method consists in the fact that before the abrasive tool is impregnated with an aqueous solution of the impregnator, the latter is treated in a constant magnetic field with an induction of at least 30 mT.

The magnetic field causes a change in the structure of the solutions, which in turn causes a change in their properties, such as solubility, surface tension, viscosity, corrosion activity, and others. The nature of the dependence of the physical properties on the induction of the magnetic field is of a complex non-monotonic nature, therefore, the choice of magnetization modes is carried out experimentally. It has been established that a constant magnetic field with an induction of less than 30 mT does not significantly affect the performance properties of an abrasive tool impregnated with a magnetized aqueous solution.

carried out

The proposed method is as follows.

The solution impregnator is passed through a device for water magnetization, for example, type CO-2. Here, the magnetic field induction in the gap is 100 mT (example 2) and 25 mT (example 3). If necessary, the magnetization procedure is repeated. After that, the magnetized solution is used to impregnate the abrasive tool.

The tests were carried out on a surface grinding machine ZB70V abrasive circles software 150X10X32 24A25SM16K5.

Samples for grinding were plates of steel R6M5 (NKSbZ-65) with a size of 200X20X20 mm.

The tests were carried out with the following grinding modes:

Circle speed, m / s35

Table speed, m / min4

Cross feed

mm / move

Grinding depth, mm

0.5

0.02; 0.04; 0.06

Evaluation of the effectiveness was carried out on 5 grinding power and on the time of occurrence of burns on the sample. Measurements of the removal of grinded steel were made every 5 mm change in diameter of the wheel.

The test results are presented in table 0.

Abrasive wheels impregnated according to Example 2 are characterized by an increase in the operating time until the appearance of burns on the sample 1.1 times, a decrease in the power of 5 grinding by 1.2 times. In addition, the working conditions of the circle are improved (the brining decreases, the circle runs smoothly).
