A complete set of numerical control (CNC) machine tools system usually consists of the following key parts:

Information input and output devices, including disk drives, dedicated data interface devices, keyboards, computers, etc., are used for program entry, modification and transmission.

The network connection system, including Ethernet interface, HSSB, processing local area network, RS-232C communication port and other industrial networks, is used to achieve communication and data sharing with external devices or systems.

External mechanical axis control units, such as automatic table changing devices, loading and unloading robots, tool magazine drive axes, etc., are used to assist in the automatic switching and positioning of workpieces or tools during the processing.

The feed servo drive and motor system controls the feed motion of the worktable or tool, ensuring high precision and stability.

The spindle motor and drive unit provide the rotational power of the spindle and are the source of the cutting force during the machining process. 

The numerical control unit, also known as the CNC controller or core control module, is responsible for converting the processing program into specific motion instructions and controlling the operation of each motion axis and actuating component.

Programmable mechanical controllers are used to control auxiliary functions of machine tools, such as coolant opening, tool changing actions, door lock control, etc., to achieve automated process control.

The position feedback and measurement system, including encoders, grating rulers and other equipment, is used for real-time monitoring and feedback of the position and status of each axis to ensure processing accuracy.

The input and output units of control signals are integrated in the electrical control cabinet and are used to achieve signal interaction between the machine tool and various actuating components, such as sensor input, relay output, etc.

When purchasing CNC machine tools, multiple factors such as the type of enterprise, product process requirements, output, and factory power supply need to be comprehensively considered.

The type of enterprise will directly affect the scale and functionality of the required equipment. A small processing workshop may only need a few basic CNC engraving machines. Large manufacturing enterprises, on the other hand, tend to choose multi-axis and high-efficiency compound machining centers.

Different products have different requirements for processing methods. If the main production is for simple-structured parts, such as two-dimensional parts or basic contour parts, a three-axis machine tool can meet the requirements.

Different products have different requirements for processing methods. If the main production is for simple-structured parts, such as two-dimensional parts or basic contour parts, a three-axis machine tool can meet the requirements.

However, if the processing involves complex structures and multiple surfaces, five-axis machine tools or compound processing equipment should be given priority. They can complete the processing of multiple surfaces in one clamping, improving efficiency and reducing errors.

Machine tools are bound to experience wear and tear or malfunction during long-term operation. Therefore, before purchasing, it is necessary to confirm whether the spare parts of the selected brand are easily accessible and whether the after-sales system is complete. This is directly related to maintenance efficiency and production interruption time.

The hardness and properties of the processed materials directly determine the rigidity and precision requirements of the selected machine tool. When processing high-strength alloy steel, equipment with high rigidity and high stability should be selected. Ordinary low-carbon steel or aluminum alloy can be used with general-purpose CNC machine tools.
