In addition, the high hardness of the material being cut, and the high efficiency of the tapping operation, the tapping material should meet the requirements of various conditions. If high temperature strength is necessary, the high-speed tool steel (CO) may be selected, or In the case of wear resistance, high vanadium (V) high speed tool steels were selected.
The tolerance of the eccentricity between the shank and the threaded part is stipulated in Table 5 according to the JIS specification. This eccentricity is large. When cutting, it requires external force. The internal thread will expand and it is easy to make the wire break or break the edge of the blade. It is important to use high-precision wire tapping.
Helix-shaped projections with specific cross-sections are made on the surface of a cylinder or cone-shaped body. The thread is divided into triangular threads, rectangular threads, trapezoidal threads, and zigzag threads according to its cross-sectional shape (dental shape). Among them, the triangular thread is mainly used for the connection (see thread connection), and the rectangular, trapezoidal and zigzag threads are mainly used for the transmission. The thread is called the external thread on the external surface of the mother's body, and is called the internal thread on the surface of the mother's body. The thread formed on the cylindrical body is called a cylindrical thread, and the thread formed on the cone body is called a conical thread. Threads are divided into two types, left-handed and right-handed, depending on the direction of the helix. Normally, right-handed threads are used. Thread can be divided into single-line and multi-line, and the connection is mostly single-line; when it is used for transmission, it requires fast-elevation or high-efficiency, double-line or multi-line, but generally not more than 4 lines.
