At present, the application of titanium alloy is more and more extensive, and higher quality and economic requirements are also proposed for processing. It is quite difficult to attack a titanium alloy with an ordinary tap. An ordinary tap can only be used without a thread. I sharpened the ordinary taps (small taps can be cut with diamond assorted (?)), so that an ordinary tap can attack more than 10 threads with an accuracy of more than 3 levels. The method comprises the following steps: grinding the back angle of the ordinary tap to about 10°~13°, leaving the cutting edge to O.2~0.3mm, and adding some vegetable oil or soybean oil in the tapping process is better.
