Taps

Cemented carbide taps processing thread dedicated tool. Especially, small-diameter internal thread processing, processing of mass production of the internal thread, a cylindrical or conical inner thread processing, using cemented carbide taps tapping is the best choice. It is simple in structure, easy to use and can be manually operated, but also in machine tool applications. In addition cemented carbide taps there are many kinds of structure, to meet the needs of different work for conditions tapping. Therefore, it is the most widely used internal thread processing tools.

The thread processing features cemented carbide taps are different from turning, milling and the like are open cutting tool, closed cutting tool is different from the broach like. Turning tools cutting its chips can be in a free state expelled naturally; cutter cutting its chips can only be fully retained in the capacity of crumbs tank. The cemented carbide taps turning tools, milling cutters, straight flutes taps through hole tapping, for example, chips in addition to the forward portion discharge, and backward discharged, the vast majority of retention the chip flutes with the bottom hole of the workpiece was half the enclosed space. And if the blind hole tapping, even able after chip removal, good chip evacuation spiral flute taps, the chip can only be limited space between the calm flute and bottom hole outflow.

Cemented carbide taps and other tooling process is also different, complete cutting tapping the forward rotation, the general must also reverse rotation to exit outside the workpiece, and keep the blade intact.

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.

Chinatungsten Online can provide various sizes and grades of cemented carbide cutting tools, non-standard products are also customized according to customer requirements. Welcome to consult and purchase sales@chinatungsten.com, sales@xiamentungsten.com .
