A technology of axial machining of a hub-type part with a high performance tool
Abstract
Basic technological process of producing holes in the hub of the epicycle MTZ using the tool: center drill, twist drill, countersink is analyzed. Modes are chosen for the base treatment process and the tool life was measured. The tests of the instrument with a modified geometry series DRILL RUSH are conducted. The optimal treatment regimens are found and the tool life is measured. It was found that in the area of optimum cutting resistance the life of one of the drill head series DRILL RUSH is within 240-260 machined hubs. Significantly higher than the tool life for the base variant 20-80 times. A performance of the drilling operation for 12 holes is increased by 24 times.
