Working Principle of Engraving and Milling Machining Cent

Engraving and milling machining center is a high-precision processing equipment that combines CNC engraving and milling functions. Its working principle is based on the integrated control of multi-axis motion, cutting parameters and auxiliary systems by computer numerical control (CNC) technology. Through the digital instructions input by programming, the equipment can accurately perform processing tasks such as engraving, milling and drilling of complex shapes, and is widely used in mold manufacturing, precision parts processing, handicraft production and other fields.
The core operating mechanism of the engraving and milling machining center begins with the instruction parsing of the CNC system. The operator designs the workpiece model through CAD/CAM software and generates G code programs. These codes define key parameters such as tool path, spindle speed, feed speed, etc. After receiving the instructions, the CNC system converts them into electrical signals to drive the servo motor, and then controls the linear motion of the X, Y, and Z axes. Some high-end models are also equipped with rotating axes to achieve five-axis linkage processing, thereby completing high-precision cutting of complex surfaces.
As the power core of the engraving and milling machining center, the spindle system usually uses a high-speed brushless water-cooled motor with a speed range of 0~24,000 RPM. The output torque and speed are adjusted by the inverter to adapt to the processing requirements of different materials. During the processing, the cooling and lubrication system sprays coolant to reduce the temperature of the tool and the workpiece, reduce thermal deformation and extend the tool life. At the same time, the dust removal system absorbs the dust generated by cutting to ensure a clean processing environment. In addition, the feedback system monitors the position and movement status of each axis in real time through sensors such as grating rulers and encoders to form a closed-loop control, ensure that the positioning accuracy can reach ±0.002 mm, and dynamically adjust the cutting parameters to avoid overload or vibration.
The workflow of the engraving and milling machining center can be summarized as follows: After the workpiece is clamped and fixed, the CNC system parses the G code instructions, drives the tool to move along the predetermined trajectory, and cuts the material in layers through the high-speed rotating spindle.
