The CNC-integrated center frame is a key load-bearing part critical for safe high-speed rail operation. Counterbores in deep cavities (Fig. 1) need EDM, causing long cycles, poor finish, and clamping issues. CNC milling was adopted for counterbores to replace EDM, cut costs, and boost efficiency. Problem analysis and process test
Compared to ordinary machine tools, CNC milling machines offer significant advantages in the production process.
With its flexibility and adaptability, CNC milling handles complex contours and size-sensitive parts like molds and shells.
With the development of aerospace manufacturing technology,Aerospace product structures are becoming more complex, with rising accuracy requirements. To increase the effective load, the parts themselves are becoming lighter and lighter. Deep-cavity thin-walled parts are lightweight, mechanically strong, and evenly load-bearing, boosting their use. A deep-cavity thin-walled part requires high accuracy,
Thin-walled parts have structural characteristics that affect their machining. They are less rigid when machining on a CNC lathe. As a result, several issues arise, such as difficulty positioning the workpiece. The parts are also prone to deformation after machining. Additionally, it is challenging to ensure the surface roughness of the parts.
