CNC machining can be applied to many types of parts, mainly including the following categories:
Box parts: These parts usually have multiple hole systems, inner cavities, and specific length, width, and height ratios. They are widely used in industries such as machine tools, automobiles, and aircraft manufacturing. The machining of box parts usually requires multi-station hole systems and flatness, and has high tolerance requirements, especially shape and position tolerances.
Complex curved surface parts: Complex curved surfaces are particularly important in mechanical engineering and aerospace industries. Ordinary machining methods are difficult or even impossible to complete the machining of such parts. Common complex curved surface parts include various impellers, guide wheels, spheres, curved surface molds, propellers, etc.
Special-shaped parts: These parts have irregular shapes and usually require multi-station mixed machining of points, lines, and surfaces. The machining of special-shaped parts requires special processes and equipment to ensure machining accuracy and efficiency.
Discs, sleeves and plates: These parts include discs with distributed holes and curved surfaces, shaft parts such as keyways, end face radial hole system parts, and various motor covers. They need to choose a suitable machining center to improve efficiency and accuracy during processing.
New product prototype parts: CNC machining centers have wide adaptability and high flexibility, and can quickly change the processing object. By compiling and entering new programs, prototype processing of new products can be easily achieved.
The main types of CNC machining centers and their application scenarios include:
Vertical machining center: Suitable for machining discs, sleeves, and plate parts. Its fixed column structure and rectangular workbench make clamping operations convenient, and it is relatively easy to observe the processing situation and debug the program. Vertical machining centers are suitable for machining parts with low heights, and they have a small footprint and are affordable, making them suitable for small and medium-sized enterprises.
Horizontal machining center: Suitable for machining complex parts such as spiral lines and cylindrical cams. Although it is relatively inconvenient to observe and monitor when debugging programs and trial cutting pins, its complex structure is suitable for processing large parts, although it occupies a large area and is more expensive.
Gantry machining center: Suitable for processing large parts, with automatic tool change system and replaceable spindle head accessories, rich and diverse functions.
Universal machining center: Combining the advantages of vertical and horizontal machining centers, it can complete the processing of multiple faces after one clamping, suitable for complex parts that require multi-faceted processing
