How to Machine Components with Complex Shapes and High Precision
Machining components with complex shapes and high precision requires the use of CNC machining centers. These centers are widely employed for multi-process machining of various parts, including:
Case Accessories (Enclosure Machining)
Case accessories, commonly used in the automotive and aviation industries, often contain multiple cavities. Examples include automobile engine cylinders, gearbox components, machine tool main axle boxes, diesel engine cylinders, and gear pump shells. CNC machining centers can efficiently complete 60-95% of the machining process for such components. With their high processing efficiency and automatic tool changing capabilities, producing case accessories becomes easier by developing control plans, crafting processes, and utilizing special fixtures and cutters.
Parts with Complex Curved Surfaces
Parts with complex curved surfaces are prevalent in aviation, aerospace, and transportation fields. Examples include cams, integral impellers for aero-engines, propellers, and die cavities. Achieving the required precision and inspecting these complex parts solely with common machine tools or precision casting is challenging. However, multi-axis linkage machining centers, combined with automatic programming techniques and special cutting tools, can effectively process these parts.
Irregular Shaped Parts
Irregularly shaped parts often require multi-station machining involving point, line, and surface operations (e.g., supports and bases). CNC machining centers demonstrate their superiority in machining such complex parts.
Plate and Coat Parts
These parts typically feature keyways, radial holes, and holes or curved surfaces on the end-face. Examples include axle sleeves with flanges and motor covers. Vertical machining centers are a suitable choice for efficiently machining such parts.
Prototypes and Samples for New Products
CNC machining centers offer adaptability and flexibility for a wide range of machining tasks. By inputting new programming or modifying program segments and using special instructions, these centers enable the machining of prototypes and samples for new products. Additionally, the scale function command can be used to process parts with the same shape but different sizes. This provides convenience for single-piece, small-batch, and multi-variety production, ultimately shortening the production cycle.
By utilizing CNC machining centers and employing appropriate programming and tooling techniques, manufacturers can efficiently machine components with complex shapes and achieve high precision in their production processes.
