This paper mainly analyzes the processing technology of the hot embedded tooth drill body, that is, the machining process and the heat treatment process. By selecting the reasonable materials and processing through a series of steps, and through a large number of comparative experiments, it is

The numerical control processing technology is used to process the drilling tool, and the high-precision numerical control processing center is adopted, by matching the special wear-resistant coating cutter, the precision error of each process can be reduced by precise measurement, the production
