In the face of many parts that need to be processed, how should we match the machine tools we need, and how to choose the CNC milling machine that suits us?

1. the dimensions of the main specifications of the CNC milling machine shall be compatible with the contour dimensions of the workpiece. That is, small workpieces should be processed by small machine tools, while large workpieces should be processed by large machine tools, to achieve the rational use of equipment.

2. the structure of the CNC milling machine depends on the influence of machine tool specification and size, weight of the processed workpiece, and other factors.

3. the working accuracy of the CNC milling machine is compatible with the machining accuracy required by the process. The machine tool shall be selected according to the machining accuracy requirements of the parts. For example, the machine tool with low accuracy shall be selected for the rough machining process with low accuracy requirements. For the finishing process with high accuracy requirements, the machine tool with high accuracy shall be selected.

4. the power, stiffness, and maneuvering range of the machine tool shall be compatible with the nature of the process and the appropriate cutting parameters. If the rough machining process removes a large blank allowance and the cutting allowance is selected to be large, the machine tool is required to have high power and good rigidity.

5. convenient clamping and simple fixture structure are also factors to be considered in selecting CNC equipment. The choice of horizontal CNC milling machine or vertical CNC milling machine will directly affect the structure and machining coordinate system of the selected fixture, and directly affect the difficulty of NC programming and the reliability of NC machining. What should be paid attention to is that when selecting CNC milling machines, we should make full use of the functions of CNC machine tools and carry out reasonable development according to the needs, to expand the functions of CNC machine tools and meet the needs of products. Then, according to the selected NC milling machine, further, optimize the NC processing scheme and process route, and properly adjust the process content according to the needs.

There is also a situation in which many enterprise bosses feel that small CNC machines can only process small parts. If you buy a larger machine tool, you can process large and small parts. This kind of situation is very puzzled by the manufacturers who process both small parts and large parts.

For example, the total power of a small CNC milling machine, such as the 550 machine tool, is 7.5kW, and the average main motor power of an 850 machine in the market is about 7.5kw-11.5kw, so the total power of the 850 CNC milling machine should reach about 18kw, twice the power consumption of the 550 CNC milling machine. If you use 10 850 CNC milling machines to process small parts compared with 10 550 CNC milling machines to compare the cost of electricity, it is a lot of money. Over time, it is a lot of money.

In general, we can't blindly see the short-term purpose. We need to consider the comprehensive needs. For manufacturers that process large and small parts, we can try to allocate machine tools of different sizes. Less investment, faster returns.
