The shape of the machining surface of milling machine is generally composed of straight lines, arcs or other curves. Ordinary milling machine operators according to the requirements of drawings. Constantly change the relative position between the tool and the workpiece, and then cooperate with the selected milling cutter speed, so that the tool can cut the workpiece to process a variety of different shapes of workpieces.
CNC machine tool machining is to divide the movement coordinates of the tool and the workpiece into the smallest unit amount, that is, the minimum displacement amount. According to the requirements of the workpiece program, the numerical control system moves each coordinate by several minimum displacements, so as to realize the relative movement of the tool and the workpiece to complete the machining of the part.


  1. Parts machining has strong adaptability and flexibility, and can process parts with particularly complicated contour shapes or difficult to control the size, such as mold parts, shell parts, etc .
  2. Can process parts that cannot be processed by ordinary machine tools or difficult to process, such as complex curved parts described by mathematical models and 3D space curved parts;
  3. It can process parts that need to be processed in multiple processes after one clamping and positioning;
  4. High machining precision, stable and reliable machining quality, the pulse equivalent of numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, numerical control machining also avoids operator errors;
  5. High degree of production automation can reduce the labor intensity of the operator. Conducive to production management automation;
  6. High production efficiency, CNC milling machines generally do not need to use special process equipment such as special fixtures, and only need to call the machining programs, clamping tools and tool data stored in the CNC device when changing workpieces, which greatly reduces production cycle. Secondly, the CNC milling machine has the functions of a milling machine, a boring machine, and a drilling machine, which makes the process highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of CNC milling machines are continuously variable, so it is beneficial to choose the optimal cutting amount;
