Abstract

Complex technological processes of finishing and strengthening processing in two transitions are offered. The results of microrelief studies on flat surfaces of parts and the impact of the proposed technology on the wear resistance of parts of printing equipment are presented.The results of the experimental studies showed that with the integrated processing method, the wear resistance of the products increased by 30–33 % compared to diamond grinding and by 4–6 % compared to the products for which only the first transition of the technological process was performed.For the integrated cover production lines, a combined technical process has also been developed in two transitions. On a flat surface they form a partially regular micro relief, which is a combination of two geometric forms of micro relief in the form of straight lines and circles.At the first transition, they form a partially regular micro relief in the form of a circle by indentation with a certain load of the deforming tool. In the second transition, efforts reduce and form the partially regular micro relief in the form of straight lines. Straight lines with a deforming tool are drawn through the micro relief formed in the first stage. The outbursts that have occurred on the lap at the second transition are greatly reduced. The formed micro relief serves more precise positioning of the paper passing along the guide, and also in the case of the formation of waste paper, they are output to the production areas through the channels of the micro relief. The results of the experimental studies showed that the highest wear resistance of flat parts is achieved at the partially regular micro relief area of 27–31 %.
