Stainless steel due to the higher viscosity, poor chip breaking performance, so tapping process prone to chip or scratch the work piece thread tap chipping phenomena affect the processing efficiency and thread quality. In order to extend the life of taps, thread processing to improve quality, should pay attention to the following points:

 

  1. Design and manufacture of taps mechanical joint fittings

 Use better tap the material; the tap thread coated titanium nitride coating, can significantly improve the tap of wear resistance, heat resistance and lubricity; appropriate to increase the tap front corner; appropriate to increase the amount of tap shovel back ; reasonable choice tool heat treatment methods to tap both hardness and toughness.
 

2. Pre-piece bottom JJN-R

 Tapping should be based on the principle amount as small as possible; Bottom larvae L size is best for plus sizes trails threading 0.1-0.2MM margin; Expansion larvae L processed before tapping the best use of custom reamers. Socket elbow factory.

 

   3. The rational use of the tap
