The structural characteristics of machined parts mainly depend on their type and function. Different types of parts have different structural features. The following are some common types of parts in production and their structural characteristics:
Shaft parts: Mostly stepped rotating bodies with multiple shaft segments of different diameters, used to install bearings, gears, and other components. Structurally, the coaxiality of each shaft segment must be ensured to guarantee rotational accuracy.
Disc/Sleeve parts: Flat and rotating in shape, such as flanges and bearing housings, usually with a center hole and mounting holes. Structural characteristics include thin walls, easy deformation, and the need to ensure the perpendicularity and coaxiality of the end face with the inner hole.
Box-type parts: Complex in structure, thin and uneven in wall size, often with a cavity-like interior, used to accommodate and support other parts. Multiple machining areas are involved, including high-precision bearing support holes, flat surfaces, and low-precision fastening holes, making machining difficult.
Gear parts: Possessing a toothed structure, used to transmit motion and power. The tooth profile requires special cutting tools for machining, and the requirements for tooth pitch and tooth profile accuracy are high. After heat treatment, precision machining is often required to ensure accuracy.
