To understand the working principle of a small machining center, you first need to clarify the components of a small machining center. A small machining center is mainly composed of five parts: a CNC system, a detection device, a driving device, a machine tool transmission chain, and a servo motor. Each part has a special function. , let the editor of Xiehe Processing Factory introduce their respective working principles from these five parts.

The first part: CNC system: equivalent to the brain of a small machining center, it needs to process the electrical signals from the detection device, drive device, and servo motor, clarify the overall status of the machine tool, and make next work instructions. To give a simple example, a small machining center executes a tool change command. The detection devices involved include servo motors, spindle clamping tool sensors, and tool magazine number sensors. The system determines the spatial position of the spindle movement through the servo motor, determines whether the tool is installed on the spindle through the spindle clamping tool sensor, and determines whether the tool is installed on the spindle through the tool magazine number. The sensor confirms the number of the tool on the tool magazine at this time. The final control system uses the signals transmitted by different detection devices at different times as reference data to make the next action. The CNC system directly determines the stability of the small machining center, so the system needs to be selected carefully.

Part 2: Driving device: equivalent to the cerebellum and brainstem of a small machining center. It can process some low-level signals, such as speed and position signals transmitted from servo motors. It helps the system handle a large number of trivial tasks, and at the same time, it directly controls the operation of the servo motor. So its role is also very important.

The third part: Detection device: equivalent to skin, eyes, and ears. It needs to collect the status of the machine tool through sensors and provide movement data reference for the system. Sensor failure causes the machine tool to be unable to receive corresponding signals, which will greatly increase the accident rate.

Part 4: Servo motor: equivalent to the heart, it is the main power source of the small machining center. Since it has a built-in position sensor and speed sensor, it acts as a partial detection device. Therefore, the servo motor directly determines the accuracy of the machine tool.

Part 5: Machine tool transmission chain: It is equivalent to the muscles and limbs of a small machining center. It can transmit the power of the servo motor and serve the purpose of power transmission. It is the mechanical component that mainly determines the accuracy of machine tools.

By understanding the five important components of the small machining center, it is easier for us to understand the principle of the small machining center. The small machining center transmits signals to the system through the detection device, the system gives action instructions, the driver and transmission chain execute the action, and finally the detection device Feedback action signal, the system determines that the execution of the command is completed. This is the working principle of a small machining center. I believe that understanding the principles of a small machining center will be an important guide when purchasing a small machining center.
