“…In this regard, high requirements are imposed on the design and manufacture of machine-tools. The machine-tool must be more precise than the parts to be made [1]. Hence, there are many difficulties in their production, and one of the main problems is the manufacture of machine stands and machine slideways.…”

“…In the case of metal working machinery, both characteristics are equally important and depend directly on each other. Modern machine-tools, regardless of precision class, are able to manufacture parts of high precision, but the higher the precision and hardness of the machine-tools, the higher the productivity without losing the quality of the parts [1,3].…”

“…Slideways of metal cutting machines are the most responsible parts of the machine, on the operation of which the subsequent accuracy of parts manufacturing depends. Slideways shall comply with the following technical requirements: accuracy of relative movement, durability in accuracy, absence of vibrations during cutting, uniformity of slow movements and accuracy of installation movements, low friction forces, repairability [1].…”

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.
