The Screw thread process method of compound compound tool of the present invention, step is as follows：
1), punch position is positioned in equipment or sheet material, using the portion that drills and reams of compound tool to the position had good positioning
Put and drilled；
2), after the portion's embedded hole that drills and reams of compound tool, punched (processing workpiece lumen) using its gang tool；
3) after the completion of, punching, using tapping thread portion to carrying out thread tapping in its hole, that is, adding for screwed hole is completed
Work.
The Screw thread process method of compound tool of the present invention, described step 1) -3) in compound tool feed forward；
Described step 3) in tapping thread portion using rotation mode carry out tapping；
Described compound tool can be processed by artificial rotation process or by machinery rotation.
The compound tool that the present invention is provided, it will be drilled, fraising, and the manufacturing procedure such as tapping is disposably completed, without carrying out
Complicated device to hole and calibration so that machining accuracy is improved, and simplifies procedure, improves production efficiency.
