1. Shaft and Disc-Type Parts
Shaft-type parts are one of the most common types in CNC machining, such as drive shafts and spindles. These parts usually have a rotating body structure and require high-precision machining of outer diameters, threads, and keyways. CNC lathes can control the tool path through programming to ensure that the dimensions and geometric tolerances meet the design requirements.
Disc-type parts include gears and flanges, which usually have hole systems or complex contours. CNC milling machines and machining centers can efficiently complete drilling, tapping, and surface machining of these parts, ensuring their interchangeability and stability during assembly.
2. Box and Housing-Type Parts
Box-type parts, such as engine cylinder blocks and machine tool spindle housings, have complex structures and require multi-sided machining. These parts often have multiple hole systems, cavities, and mounting planes, requiring extremely high positional accuracy. CNC machining centers, through automatic tool changing systems and multi-axis linkage, can complete multiple processes in one go, reducing errors caused by repeated clamping.
Housing-type parts are commonly found in electronic equipment casings or hydraulic components, and their design emphasizes lightweight and aesthetics. CNC technology can precisely achieve the machining of thin-walled structures, irregularly shaped holes, and decorative patterns, balancing functional and aesthetic needs.
3. Special Curved Surfaces and Precision Small Parts
With the increasing diversification of product design, the demand for complex curved surface parts such as impellers and mold cavities is growing. These parts usually contain free-form surfaces or three-dimensional contours, which are difficult to process using traditional methods. CNC multi-axis machine tools, through digital modeling and trajectory planning, can efficiently complete high-difficulty surface cutting, ensuring the consistency of surface quality.
In addition, precision small parts such as connectors and sensor components are also typical objects of CNC machining. They are small in size and have fine structures, requiring the use of CNC precision engraving machines or high-speed milling machines to achieve micron-level machining, and are widely used in precision instruments and consumer electronic products.
4. Irregularly Shaped Parts and Functionally Composite Parts
Irregularly shaped parts refer to parts with irregular geometric shapes, such as brackets and connecting rods. They may have both rotational and planar features, requiring the comprehensive application of various processes such as turning, milling, and drilling. The flexible manufacturing capabilities of CNC machining centers are ideally suited to these needs, allowing for rapid switching between machining objects through program adjustments.
Functionally integrated components refer to parts that combine multiple functions, such as valve bodies with integrated flow channels and sensors. These parts are formed in a single process using CNC machining, reducing assembly steps and improving overall reliability.
