Abstract
The article investigated the vibration treatment of blind holes obtained by selective laser melting. The object of the investigation was a printed stainless steel specimen with holes of various diameters. The experimental results showed that the most effective treatment occurs when the hole diameter exceeds the size of the abrasive body by 1-2 mm, but does not exceed it by 2 times. It was also noted that the rounding of the edge of the hole with a size not exceeding the nominal value of the abrasive occurs faster than that of a hole with a larger size. The time of rough processing of stainless steel products should not exceed 4 hours, while the most effective processing occurs in the first 2-3 hours. The results obtained allow us to give recommendations on the processing of printed parts with blind holes made by selective laser melting.
