Multipurpose shaft parts
Multipurpose shaft parts are one of the more commonly used typical parts. It is mainly used to support transmission parts, transmit torque and bear loads. Shaft parts are rotating body parts, whose length is greater than the diameter, and are generally composed of the outer cylindrical surface, conical surface, inner hole, thread and corresponding end surface of the concentric shaft. According to different structural shapes, shaft parts can be divided into optical shaft, stepped shaft, hollow shaft and crankshaft. Shafts with an aspect ratio less than 5 are called short shafts, those greater than 20 are called slender shafts, and most shafts are in between.

Product introduction
- Shaft material
Usually mild steel is the material used for the shaft. If high strength is required, alloy steels such as nickel-chromium, nickel, chromium-vanadium steels are used. They are usually formed by hot rolling and cold drawing and grinding.
- Manufacture of the shaft
The shaft is manufactured using a hot rolling process. Compared with hot rolling, the strength of the shaft is higher when cold rolling, but cold rolling causes high residual stress, which causes the shaft to deform during processing. The forging process is used to manufacture larger diameter shafts. After the rolling is completed, the shaft is end-machined, one end of the shaft is mounted on the inspection, and the other end of the shaft is supported by the turret of the lathe. To finish the axis, the tool holds the tool holder, and when the power is turned on, the chuck starts to rotate the axis.
Dial indicators are used to check the concentricity of the shaft before machining, and perform various operations such as turning, facing, grooving, taper turning, etc., depending on the application.
Applications such as high volume, CNC, etc. are best suited for the final machining process. Machining is also possible with a CNC double-ended machine with the shaft clamped between the tool rotation and the fixture. For concentricity and roundness, the rotating tools should be opposite on the centerline. Drive shafts and motors are usually manufactured using this process.
