CNC milling machine is an automatic processing equipment developed on the basis of general milling machine. The processing technology of the two is basically the same, and the structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

The working principle of CNC milling machine:

On the milling machine, the process, process parameters, and relative displacement of the tool and the workpiece are written into a machining program list in CNC language, and then the program is input into the CNC device, and the CNC device controls the machine tools according to the CNC instructions. operations and the relative displacement of the tool to the workpiece. When the part processing program ends, the machine tool will automatically stop, and the qualified parts will be processed. The process can be divided into production process and technological process.

The production process is the whole process of converting raw materials into finished products. The technological process is to change the shape, size, relative position and nature of the production object. The process of making it a finished or semi-finished product. When CNC milling machines process parts, except for manual loading and unloading of workpieces, all the processing processes are automatically completed by the machine tool. In the flexible manufacturing system, loading and unloading, detection, diagnosis, tool setting, transmission, scheduling, management, etc. are also automatically completed by the machine tool. Completed.

What are the characteristics of CNC milling machine

• The parts processing has strong adaptability and flexibility. It can process parts with particularly complex contours or difficult to control dimensions, such as mold parts, shell parts, etc.

• It can process parts that cannot be processed by ordinary machine tools or are difficult to process. Such as complex curve parts and three-dimensional space surface parts described by mathematical models.

• Parts that need to be processed in multiple processes after one clamping and positioning can be processed.

• High processing precision, stable and reliable processing quality. The pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical control system can reach 0.1μm. In addition, the numerical control processing also avoids the operator's operating errors.

• The production automation is high, which can reduce the labor intensity of the operator. Conducive to production management automation.

Basics of CNC Milling Machines

• When entering the workshop for internship, you should wear work clothes, the large cuffs should be fastened, and the shirt should be tied into the pants. Female students are required to wear hard hats and incorporate their tresses into the hat. Sandals, slippers, high heels, tank tops, skirts and scarves are not allowed into the workshop. Note: Gloves are not allowed to operate the machine;

• Be careful not to move or damage the warning signs installed on the machine;

• Be careful not to place obstacles around the machine tool, and the working space should be large enough;

• When a certain job requires two or more people to complete it together, attention should be paid to mutual coordination;

• It is not allowed to use compressed air to clean machine tools, electrical cabinets and NC units;

• The practice should be carried out on the designated machine tools and computers. Without permission, other machine tools, tools or electrical switches are not allowed to tamper with.
