Stainless steel flange material particularity and cutting technology
Stainless steel flange material is high viscosity, poor chip breaking performance, so in the stainless steel flange tap tap process is prone to chip scratching workpiece thread or tap edge, affecting the processing efficiency and thread quality. In order to prolong the service life of stainless steel flange taps, improve the quality of thread processing, where processing and production should pay attention to some matters needing attention:
Choose better tap material. The wear resistance and toughness of tap can be improved by adding special alloying elements into ordinary high speed tool steel.
The wear resistance, heat resistance and lubricity of tap can be significantly improved by coating the surface of tap thread with titanium nitride coating.
Properly increase the amount of tap shovel back. However, it should be noted that, if the amount of shovel back is too large, it is easy to produce chips stuffed into the back corner of the tap when the knife is withdrawn, and the thread finish is not good.
Reasonable selection of tool heat treatment method, in order to give consideration to the hardness and toughness of taps.
Properly increase the front Angle of the tap. However, it should be noted that if the front Angle of the tap is too large, it is easy to cause the tap to break the edge and tap out the multi-edge thread.
