To understand the working principle of a small machining center, it is necessary to first clarify the components of the small machining center. The small machining center is mainly composed of five parts: numerical control system, detection device, drive device, machine tool transmission chain, and servo motor. Each part has special functions. Below, we will introduce their respective working principles from these five parts, so that everyone can have a certain understanding of the small machining center.

Part 1: Numerical Control System: Equivalent to the brain of a small machining center, it needs to process electrical signals from detection devices, drive devices, and servo motors, clarify the overall status of the machine tool, and make instructions for the next step of work. For 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 confirms the tool number on the tool magazine at this time through the tool magazine number sensor. The final control system uses signals transmitted by different detection devices at different times as reference data to make the next action. The numerical control system directly determines the stability of small machining centers, so careful selection of the system is necessary.

Part 2: Drive 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 by servo motors. He helped the system handle a large number of tedious tasks while directly controlling the operation of the servo motor. So its role is also very important.

Part Three: Detection Device: Equivalent to skin, eyes, and ears, it needs to collect the status of the machine tool through sensors to provide motion data reference for the system. Sensor failure causing the machine tool to not receive the corresponding signal will greatly increase the accident rate.

Part Four: Servo Motor: Equivalent to the heart, it is the main power source for small machining centers. Due to the built-in position and speed sensors, it serves as a partial detection device, and 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, which can transmit the power of servo motors and achieve the purpose of power transmission. It is the mechanical component that mainly determines the accuracy of the machine tool.

By understanding the five important components of a small machining center, we can better understand its principle. The small machining center transmits signals to the system through a detection device, and the system gives action instructions. The driver and transmission chain execute the action, and finally the detection device feedbacks the action signal. The system judges that the execution command is complete. This is the working principle of a small machining center, and I believe understanding the principle of a small machining center will have an important guiding role in choosing one.
