“…The main defects of production of the metal-cutting machine slideways at traditional technology of processing are burns, stripes, flay marks, scores, flutes, grooves, side chips and other mechanical damages of a working surface of slideways. Each deep and extended groove leads to accelerated wear of slideways and reduces smooth movements [7][8][9].…”

“…Wear resistance and smooth motion are more influenced by elongated grooves and channels. Deep grooves and channels arise due to stagnant phenomena [8,9,15], which are formed at a certain cutting speed and temperature of the cutting tool on the front and rear surfaces, in micro-volumes, around the cutting edge of the replaceable polyhedral plate (RPP).…”

“…Slideways shall provide the specified accuracy with high smooth movements, have high wear resistance and allow for wear compensation. Slideways shall also be provided with lubrication efficiency, easy assembly and adjustment, reliable protection against contamination and chips ingress on the friction surface [1,8,9].…”

Modern methods of machining of bed slideways with the required parameters of accuracy and quality of the processed surfaces are considered in order to increase productivity in the treatment of the surface of machine stands. To improve productivity, the finishing sanding operation has been replaced with finishing milling to ensure the required roughness, flatness and parallelism. The method of replacement of technological operations as exemplified by processing of a bed made of gray cast iron of grade “СЧ-20” is studied. The priority method of increasing the productivity of the processing of machine slideways of metal-cutting equipment, based on the use of cutting ceramics during the processing of the bed as a final technological operation, is determined. Based on the microstructural characteristics of oxide-carbide cutting ceramics, a uniform method of equipping cutters with cutting inserts with equal lifespan is used to increase productivity and achieve the required surface finish. This method of the milling cutter layout allows for longer life and provides the required margin of tool accuracy as well as allows predicting premature wear of the cutting tool. The results of the work are the identification of the patterns of influence of structural parameters of cutting ceramics on the quality of machine slideways of metal-cutting equipment in the selective formation of instrumentation. Studies have shown that the quality of machining depends on the microstructure characteristics of each insert used in the machining process when using interchangeable multi-sided oxide carbide ceramic inserts. The increase in productivity and quality of machining is achieved by monitoring the microstructure of the cutting oxide-carbide ceramics.
