CNC machining occupies a very high position in CNC equipment. Many parts processing enterprises will apply CNC machining centers. What types of parts can CNC machine? As we all know, CNC machining centers are suitable for machining parts that are complex, have many procedures, require high requirements, require a variety of types of ordinary machine tools and a variety of tool fixtures, and require multiple clamping adjustments before processing. The machining objects are mainly box parts, complex curved surfaces, special-shaped parts, clad plate parts and special machining.
(1) Box parts.
Box parts generally refer to parts with multiple hole systems, cavities inside, and a certain proportion of length, width and height. Such parts are mostly used in machine tools, automobile, aircraft manufacturing and other industries. Box shaped parts generally require multi station drilling and plane processing, with high tolerance requirements, especially strict form and position tolerance requirements. They usually go through milling, drilling, expanding, boring, reaming, spot facing, tapping and other processes, requiring more tools. For the machining center for machining box parts, when there are many machining stations and the worktable needs to rotate for many times to complete the parts, the horizontal boring and milling machining center is generally selected.
(2) Complex surfaces.
Complex surfaces play an important role in mechanical manufacturing, especially in aerospace industry. It is difficult or even impossible to complete complex surfaces using ordinary machining methods. In China, the traditional method is to use precision casting, which can be imagined to be low in accuracy. Complex surface parts, such as various impellers, wind deflectors, spheres, various surface forming molds, propellers, underwater vehicle propellers, and other free surfaces.
