Abstract

The article describes processing blind holes when drilling stainless steel AISI 321. Helical drills made of high-speed steel with channels for the internal supply of a lubricating and cooling technological medium were used as a cutting tool. The tool’s geometry did not change, corresponding to actual production conditions. Drilling in stainless steel is always done with cutting fluids. The use of minimum lubrication technology in this operation, even if they contain various additives, is impractical due to the lack of a guarantee that the lubricant will enter the chip formation zone. An increase in the volume of process fluids requires special attention to the selection of compositions due to the tightening of requirements for the regeneration and disposal of waste media. The data obtained indicate the expediency of using vegetable-based cutting fluids in connection with their effect on reducing contact pressures and the height of the micro-roughness of the treated surface.
