Abstract
In the article is considered improvement of quality and performance properties of machines, mechanisms and processing equipment. The fail of service performance and the accelerated failure during operation usually are the result of processes that take place on the surface layers of parts.A significant place in solving these problems is given to the development of new technological processes design of equipment and rational choice of materials for their parts in order to ensure the necessary performance properties of the material from which they are made.One of the important directions of increasing the operational properties of the parts of printing equipment is to obtain the specified properties of the surfaces of the parts by methods of surface hardening.Increasing the operational properties is the combination of galvanic and chemical methods of coating with the simultaneous formation of regular microreliefs on the surface by methods finishing-strengthening treatment. Due to its high corrosion resistance and wear resistance, chromium coating is already used as a protective agent in many industries.When solving the problems of technological quality assurance of the parts' surface and operational properties it is necessary to provide the quality parameters of the surface layer of machine parts according to their purpose in order to predict the processing modes and determine the complex of processing methods that deliver the quality of the set of surface layer parameters with the highest productivity.For purposeful control of technological processes, an algorithm of complex technological process was developed on the basis of the analysis of the specified technological scheme for the calculation of geometric parameters in the case of partial-regular microrelief formation after vibration run-in and chrome plating. The automatic control system adds new features to printing equipment, making it possible to execute a large number of high-quality orders in short time.

Improvement of quality and performance properties of machines, mechanisms and processing equipment is an urgent issue of modern mechanical engineering
Research results The basis of the proposed complex technological process is set to improve the quality of the surface and surface layer, as well as operational properties by forming of a partially regular microrelief of a sinusoidal type on the cylindrical surfaces, in which there is no intersection of irregularities, with subsequent application of chromium layers on these surfaces, that change according to the size of the deposited layer
