Characteristics of CNC Milling Machine – Calculation Method of Surface Velocity of End Milling Cutter

The biggest CNC milling machine features are:

1. Parts processing has strong adaptability and flexibility, and can process parts with particularly complex contour shape or difficult to control size, such as mold parts, shell parts, etc.

2. It can process 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 space curved surface parts;

3. It can process parts that need to be processed in multiple processes after one-time clamping and positioning.

4. The machining precision is high, and the machining quality is stable and reliable. The pulse equivalent of CNC device is generally 0.001mm, and the high-precision CNC system can reach 0.1 μ m. In addition, the errors of CNC operators are avoided.

5. High degree of production automation can reduce the labor intensity of operators. It is conducive to the automation of production management.

6. With high production efficiency, CNC milling machines generally do not need to use special process equipment such as special fixtures. When replacing workpieces, they only need to call the processing program, clamping tools and adjusting tool data stored in the CNC device, which greatly shortens the 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 speed of CNC milling machine are stepless, so it is helpful to select the best cutting parameters.
