Cemented Carbide Taps Feature - part 2

The cemented carbide taps are multi-blade cutter; the process of thread is cut out from the prepared hole of the workpiece, each rotation of the tap, axially moving a pitch. Each screw thread type cutting workload, and is shared by a few teeth of the cutting cone portion, taper taps, not only is shared by the portion of the cutting cone, several teeth, as well as to the location of the base surface after the cutting cone teeth sharing. When the pitch P of certain circumstances, as the increase or decrease of the number of slots N, the amount of each cutting tooth also be reduced or increased. Likewise, cutting the cone angle of Kr decreases or increases, i.e. increase or decrease of the number of teeth of the cutting cone, would decrease or increase amount of each cutting tooth. The amount of each tooth cutting after cutting cone taper taps are relatively balanced. Therefore, in the thread cutting process, the participation of each tooth of the cutting cone, a certain thickness of the metal layer is cutaway. Cemented carbide taps total cutting workload is the metal layer is cut area sum. Thus cemented carbide taps cutting characteristics, which is, cutting small thickness.
