CNC milling machines are a type of automatic processing equipment developed on the basis of general milling machines, with similar processing techniques and structures. CNC milling machines are divided into two categories: without tool library and with tool library. CNC milling machines with tool libraries are also known as machining centers.
In addition to the characteristics of ordinary milling machines, CNC milling also has the following characteristics:
1. The adaptability and flexibility of part processing are strong, and it can process parts with particularly complex contour shapes or difficult to control dimensions, such as mold parts, shell parts, etc;
2. Capable of processing parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional curved surface parts;
3. Parts that require multiple processing steps after one clamping and positioning process;
4. High machining accuracy and stable and reliable machining quality. The pulse equivalent of CNC devices is generally 0.001mm, and high-precision CNC systems can reach 0.1 μ m. In addition, CNC machining also avoids operator errors;
5. High level of production automation can reduce the labor intensity of operators. Beneficial to automation of production management;
6. High production efficiency, CNC milling machines generally do not require the use of specialized process equipment such as specialized fixtures. When replacing workpieces, only the processing program, clamping tools, and tool data stored in the CNC device can be called, thus greatly shortening the production cycle. Secondly, CNC milling machines have the functions of milling, boring, and drilling machines, making the processes highly concentrated and greatly improving production efficiency. In addition, the spindle speed and feed speed of CNC milling machines are continuously variable, which is conducive to selecting the optimal cutting amount.
