The tapping thread portion is the firm screw tap of tungsten, and it is embedded on tool rest, and its outer wall is provided with and moves back bits groove;Tapping spiral shell Line portion external diameter is more than preceding tool rest external diameter;
Tool rest is additionally provided with three (or four) triangle turning inserts after described, is respectively used to car workpiece end face, car workpiece outer wall Edge chamfering, turner part aperture edge chamfering;One Rinorea bengalensis blade cutting edge is used for perpendicular to tool rest axis (being used for face work) The Rinorea bengalensis blade tilt of car chamfering is on the tool rest, and its blade and aperture are into 30 ° of -45 ° of angles;
Tool rest is provided with chip area afterwards;It is described to move back bits cavity, move back bits groove, chip area and be sequentially communicated.
Compound car described in the utility model attacks the Screw thread process method of compound tool, and step is as follows:
1), punch position is positioned in equipment or sheet material, the portion that drills and reams of compound tool is attacked to having good positioning using car Position drilled;
2) after, car attacks the portion's embedded hole that drills and reams of compound tool, punched (workpieces processing inner chamber) 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.
Car described in the utility model attacks the Screw thread process method of compound tool, described step 1) -3) in car attack it is compound Cutter is fed forward;
Tapping thread portion carries out tapping using rotation mode in described step 3);
Described car is attacked compound tool and can processed by artificial rotation process or by machinery rotation.
Car provided by the utility model attacks compound tool, and it will be drilled, the manufacturing procedure such as fraising, tapping is disposably completed, Without carrying out complicated device to hole and calibration so that machining accuracy is improved, and simplifies procedure, improves production effect Rate.
