The Effect of Electrolytic Strengthening Treatment on Tap’s Service Life

Abstract:

In this study High-speed steel taps are taken as the research object. Electrolysis technology was used to deal with the taps in various count time (7s 14s 21s 28s 35s) and then obtain the corresponding radii of the cutting edge (11.38μm 15.05μm 20.35μm 23.00μm 25.55μm). The experimental results exhibit quantitatively the effect of tool radius on the performance of tapping. A radius on the cutting edge prevents fast and unpredictable wear. Moreover, the existence of an optimum value of the radius has been revealed experimentally. Tapping test is used to prove the optimal cutting edge radius is 15.05μm and the taps life increase about 2.5 times than usual taps. It can provide an important theoretical basis for the modifications of the cutting edge radius and give a method to improve tap life.
