What parts are commonly used in CNC?
Add Time：2025-03-28
The CNC machining center is suitable for complex machining, multi-process, high requirements and high demand, various types of ordinary machine tools and various fixtures, parts that need to be clamped and adjusted several times. Its processing objects are mainly box parts, complex surfaces, special-shaped parts, composite plate parts and CNC processing.
First. Box parts
Box parts generally refer to parts with a porous system, an inner cavity and a certain length, width and high proportion. Such parts are mainly used in machine tools, automobiles, aircraft manufacturing and other industries. Box parts generally need multi-station hole and surface processing, high tolerance requirements, especially the shape and position tolerance requirements are relatively strict. They usually go through milling, drilling, expanding, boring, reaming, spot welding, tapping, and other processes that require more tools. The machining center is used to process the box parts. When there are multiple processing stations and the parts can only be worked, the boring and milling machining center is generally selected.
Second. Complex surface
Complex surfaces play a very important role in machinery manufacturing, especially in the aerospace industry. Using ordinary machining methods, it is difficult or even impossible to complete complex surfaces. In China, the traditional casting method is precision casting, and it can be imagined that its precision is low. Complex curved parts.
Third. special-shaped parts
Special-shaped parts are irregular parts, most of which require multi-station processing of points, lines and surfaces. The stiffness of special-shaped parts is generally poor, the clamping deformation is difficult to control, the processing accuracy is difficult to ensure, and even some parts of some parts are difficult to complete with ordinary machine tools. When processing with the machining center, reasonable technological measures should be taken to carry out one or two clamping, and the processing characteristics of the machining center mix have multiple stations, which can complete multiple or all processes
Fourth. Discs, sleeves and plates
For disk parts with keyway or radial hole or distributed hole system, curved disk sleeve or shaft zero, such as flange shaft sleeve, keyway or square head shaft parts and porous machining plate, should choose vertical machining center, such as a variety of motor end face with distributed holes and curved disk parts, should choose horizontal machining center with radial holes.
