For the processing of ordinary internal threads on nuts or other machine parts (i.e., tapping). Machine taps usually refer to high-speed steel grinding taps, which are suitable for tapping on machine tools; Hand tap refers to carbon tool steel or alloy tool steel roll (or incisor) tap, suitable for hand tapping.
Tap is a tool for processing a variety of medium and small size internal threads, it is simple in structure, easy to use, can be manually operated, can also work on the machine tool, and is widely used in production.
For small internal threads, the tap is almost the only machining tool. The types of tap are: hand tap, machine tap, nut tap, extrusion tap and so on.
Tapping is a more difficult processing process, because the tap is almost buried in the workpiece for cutting, the processing load of each tooth is larger than other tools, and the tap along the thread and the workpiece contact surface is very large, cutting the thread it must accommodate and exclude chips, therefore, it can be said that the tap is working in very harsh conditions. In order to make the tapping proceed smoothly, various problems that may arise should be considered in advance. Such as the performance of the workpiece material, what tools and machine tools to choose, how high cutting speed to choose, feed, etc.
