Stainless steel tapping：
1. When tapping stainless steel thread, the phenomenon of “dwelling” is more serious, and the tap is easy to “bite” in the hole, so the bottom hole of the thread should be properly increased. In general, the diameter of the threaded bottom hole with a pitch of 1 mm or less is equal to the nominal diameter minus the pitch; when the pitch is greater than 1 mm, the diameter of the threaded bottom hole is equal to the nominal diameter minus 1.1 times the pitch.
2. Choosing the right tap and reasonable cutting amount is the key to the quality of tapping. Tap material should be selected from cobalt or super hard high speed steel. For the straight groove tap, the front end of the tap can be modified into a spiral shape; the front angle of the tap is generally γp=15°-20°, and the back angle is 8°-12°.
3, the use of slotless taps for stainless steel tapping.
4, stainless steel tapping, should try to use stainless steel special tapping oil.
5. In the process of tapping, if the tap is broken, the workpiece can be placed in a nitric acid solution for corrosion, and the high-speed steel wire cone can be quickly corroded without scrapping the workpiece.
6. The third job was launched very early on, specializing in stainless steel special wire tapping. The effect of processing stainless steel is very good and can be tried.
