“…Most of the grains are not taking part in the overall micro cutting process or participates in it in a minimum volume, deforming and heating the metal. The share of active grains, ensuring the removal of metal, according to the data of various researchers, is only 10-15% of their potential possibilities [11]. Thus, there is a substantial reserve of unused grains possibilities, determined by their relatively low physical and mechanical properties, and also by their unfavorable and uncollected geometry of cutting parts.…”

Abstract. The aim of the article is to find out ways to improve parts treatment and components of mining equipment on the example of hydraulic cylinders parts, used as pillars for mine roof supports, and other actuator mechanisms. In the course of the research work methods of machine retaining devices design were used, the scientific approaches for the selection of progressive grinding schemes were applied; theoretical and practical experience in the design and production of new constructions of grinding tools was used. As a result of this work it became possible to create a progressive construction of a machine retaining device for grinding of large parts of hydraulic cylinders, to apply an effective scheme of rotary abrasive treatment, to create and implement new design of grinding tools by means of grains with controllable shape and orientation. Implementation of the results obtained in practice will improve the quality and performance of repairing and manufacturing of mining equipment.

“…Despite the large number of advantages presented above, there is a relatively low efficiency in the use of the potential capacities of coated abrasive tools, as well as of any other abrasive tools. In many ways, this result is predetermined by the use of standard abrasive in the manufacture of tools, when the shape and orientation parameters of grains relative to the substrate are not taken into account [5][6][7][8][9][10][11].…”

The issues of the influence of the orientation and shape of grinding grains of coated abrasive tools on their basic performance characteristics are considered in the article. The advantages of machining with flexible grinding tools are listed. The features of the abrasive grains contained in tools on a flexible basis are presented. The low efficiency of using standard tools is justified. A method is described for increasing the efficiency of the grinding process with tools on a flexible basis due to an integrated approach to the design of new tool designs. It is proposed to use abrasive grains of a given shape and oriented in a certain way relative to the surface of the tool base. The main stages of work related to the development of new tool designs and studies of their operational characteristics are presented. Experimental data of the dependencies of cutting capability, wear, temperature in the cutting zone, power spent on cutting, and the cut surface quality on the shape and the orientation angle of grinding grains are presented. Practical recommendations for the application of tools containing in their structure certain varieties of grinding grains are proposed.

“…Such methods include the development of fundamentally new designs of grinding tools containing in their structure abrasive grits of a certain shape and orientation. A lot of works devoted to the study of the influence of the shape and orientation of abrasive grains on the performance characteristics of various grinding tools convincingly prove the importance of this area of activity [1,2,[4][5][6][7][8][9][10][11][12][13][14][15][16].…”

The article is devoted to the research of strength properties of single abrasive grits of various shapes. The existing methods for determining the strength of abrasive materials are analyzed. Data are presented on the pattern of stresses arising in abrasive grits under various schemes of applying loads to them, obtained by computer simulation. The results of static strength tests of regular alumina grains by the method of uniaxial compression, as well as observations of the influence of the orientation and shape of abrasive grits on its impact strength, are presented.
