[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission components, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts; or they can be divided into solid shafts, hollow shafts, etc.

[0003] In industrial applications, shafts are used for maintenance operations on one or more CNC machine tools. They support transmission components such as gears and pulleys within the machine to transmit torque or motion. Shafts are rotating parts whose length is greater than their diameter. They typically consist of a concentric outer cylindrical surface, a conical surface, an inner bore, a thread, and corresponding end faces. Shaft machining involves chamfering, a process often performed using grinding machines.
