Problems solved by technology

[0002] A tap is a tool for machining internal threads, with grooves along the axial direction. According to its shape, taps are divided into straight groove taps, spiral groove taps and spiral tip taps. Straight groove taps are easy to process, with slightly lower precision. Slower, taps can be used for through-hole processing, but many taps are prone to debris during processing when they are in use, which affects the personal safety of operators
