Function of tap

Taps are used for machining internal nuts or other internal threads on the machine (ie tapping). Machine taps are usually referred to as high speed steel grinding taps for tapping on machine tools; hand taps are carbon tool steels or alloys. Tool steel rolling (or incisor) tap for manual tapping.

The tap is a tool for processing various medium and small internal threads. It is simple in structure and easy to use. It can be operated manually or on a machine tool. It is widely used in production.

For small internal threads, the tap is almost the only machining tool. The types of taps are: hand taps, machine taps, nut taps, extrusion taps, and the like.

Tapping is a difficult machining process because the tap is almost buried in the workpiece for cutting. The machining load per tooth is larger than that of other tools, and the tap is very large along the thread and the workpiece. When cutting the thread It must contain and remove chips, so it can be said that the taps work under very harsh conditions. In order for the tapping to proceed smoothly, various problems that may arise should be considered in advance. Such as the performance of the workpiece material, the choice of tools and machine tools, how high the cutting speed, feed rate, etc.
