Wear Properties of Aluminum Alloy 211z.1 Drilling Tool.

In the application process of China's independently produced new aluminum alloy 211z.1 into high-end military and civilian industries, a great many holes are needed for fastening connection. However, the severe wear of the cutting edge of twist drill is an important factor that restricts the quality of hole processing and tool life. In this paper, the wear condition of the standard high-speed steel twist drill in drilling the new aluminum alloy 211z.1 is studied based on the drilling test, and the influence law of the drilling amount on the tool wear is revealed by designing a reasonable drilling test plan. The research results show that the cutting speed has a significant effect on the flank wear, and the drilling feed and the drilling height have relatively little influence on the flank wear of the tool.
