ssessment of cutting fluids supplying method influence on contact processes when drilling stainless steel 12Х18Н10Т

The authors have considered the process of blind holes processing during drilling operations when processing stainless steel 12Х18Н10Т. Spiral drills made of high-speed steel were used as cutting tools. There are some typical problems in this process such as difficulty of removing chips and cutting fluids supply to the machining zone. One more problem is that while removing chips along spiral grooves, they rub against the surface of the hole and thus become deformed, which results in the deterioration of surface quality. Therefore, a comparative assessment of various coolants influence was carried out depending on the method of their supply under closed cutting conditions.
