The advantages of CNC milling process: (1) It can process parts that are usually not machined or difficult to machine, such as chaotic curve parts and three-dimensional space surface parts described by mathematical models; (2) Parts that can be processed by multiple processes after milling can be machined once; (3) High production efficiency, CNC milling machines usually do not need special processing equipment such as special fixtures. When replacing workpieces, it is only necessary to call the machining program, clamping tool and tool data stored in the numerical control equipment, which greatly shortens the number. Production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed rate of CNC milling machines are infinitely variable, which is beneficial to select the best cutting amount.
