Dalian CNC machining is a process method for machining parts on CNC machine tools. The process specifications for CNC machine tool machining and traditional machine tool machining are generally consistent, but there have also been significant changes. The mechanical processing method that uses digital information to control the displacement of parts and cutting tools is an effective way to solve problems such as variable part varieties, small batch sizes, complex shapes, high precision, and achieve efficient and automated processing.

From the beginning, CNC machine tools select aircraft parts with complex profiles as the machining objects, solving the key problems that ordinary machining methods are difficult to solve. The biggest feature of CNC machining is the use of perforated tape (or magnetic tape) to control the machine tool for automatic machining. Due to the different characteristics of aircraft, rockets, and engine components: large component sizes and complex profiles of aircraft and rockets; Engine components have small dimensions and high precision.
