Workpiece material machinability is the key to tapping. Tap manufacturers main concern now is to develop

Taps for a particular material. The properties of these materials, tap change geometry of the cutting parts, in particular its horn and depressed (HOOK)-previous depressed levels. The highest processing speed is sometimes limited by the performance. For smaller males, spindle speed in order to reach the desired speed [RPM= (SFM x 3.8) diameter/tap], may have more than the maximum spindle speed. The other hand, high speed cutting with larger taps will produce greater torque, larger than the horsepower provided by the machine. 700psi cool tools, cutting speeds may reach 250sfm. Without the cooling facility machine tool, cutting speed can only be up to 150sfm. Males are different from most of the metal-cutting tools, because it and the hole wall of workpiece contact area is very large, so cooling is essential. If HSS taps overheating, then push wire broken, burned, NORIS high performance wire hung geometry features is the large posterior horns and inverted cone. ”
