1. Tap design and manufacturing

(1) use a good tap material. Add special alloying elements in ordinary high-speed tool steel, can significantly improve the wear resistance and toughness tap.

(2) In the tap thread coated titanium nitride coating, can significantly improve the tap wear resistance, heat resistance and lubricity.

(3) increase the tap before the appropriate angle. It should be noted that, as the tap before the angle is too large knife in the back is likely to cause chipping and tap-tapping the threads polygonal.

(4) appropriate to increase the tap shovel back. It should be noted that, as the shovel back too large knife in the back corner prone to the phenomenon within the chip into the rear tap and tapping out the thread finish poorly.

(5) a reasonable choice tool heat treatment methods to tap both hardness and toughness.

2, the rational use of tap

Processing should take into account different types of chips to the workpiece. When necessary, also need to tap new grinding, grinding principle is to try to keep calm when tapping the chip discharge flutes, to prevent scratching the machined thread.
