The article deals with the method of obtaining a hard chromium coating with using abrasive tool. The influence of the pressing force of the abrasive tool, the rotation speed of the part, the temperature of the electrolyte on the results of galvanomechanical chromium plating of rotating cylindrical parts has been studied. A special abrasive tool has been developed for use in the galvanic mechanical coating of metal parts. The tool is made on a polymer bond. The effect of the electrolyte temperature on the quality of the precipitated chromium is revealed.

The article presents the results of experimental studies of the influence of polymer abrasive granules shape on the surface roughness formation and metal removal during vibrational finishing and hardening treatment (VFHT). As is known, surface roughness and the amount of metal removal are affected by a number of factors: binder material, material and granularity of the abrasive, technological lubricant-coolant medium (LCM) type, loading mass, initial roughness, etc. Processing was carried out for 120 min on a UVG-4x10 vibrating machine, with a working chamber volume of 10 dm3.

In the article, the results of the analysis of wear and tear of face milling cutters, equipped with an abrasive polymer compound, which are composed of quartz fine-grained sand and epoxy-diane resin, are shown. It has been established that the prevailing mechanism of tool wear during the processing of such a composite is abrasive wear. The reliability of the characteristics of wear and tear resistance of the cutting tool in the form of a sharpness of cutting was assessed.

Polymer-abrasive brush rotating tools are increasingly used for finishing operations in automated manufacturing. Given this, studying the process of their fibers’ wear has become important; and such a type of wear as the detachment of a whole fiber at the point of fixing has not been investigated in detail up to now. This phenomenon can lead to the disruption of stable equipment operation and the catastrophic wear of brushes. Therefore, it is a relevant task to search for and identify those limitations that could prevent fibers from detachment. This study involved the disc and cylindrica

Abstract Proper bonding of coatings and linings to concrete surfaces requires proper cleaning and frequently requires the concrete to be roughened to increase the surface area. The roughness, also known as surface profile, can be imparted into concrete by abrasive blast cleaning, acid etching, or various impact/scarifying power tools. The resulting surface profile depth can influence coating/lining adhesion and performance. Coating/lining manufacturers and/or facility owners frequently specify cleaning and roughening of the concrete surface prior to product installation. The surface profile (r

Abstract. The article is devoted to the study of the wear intensity of elastic polymer-abrasive circles when processing the surfaces of parts made of high-strength aluminum alloys. Empirical dependencies of wear on cutting speed and tool deformation are obtained, on the basis of which method of tool deformation correction with long-term, continuous surface treatment is proposed. In practice, such a procedure is necessary due to the loss of process performance that occurs due to the reduction of tool deformation due to wear.
