High-accuracy CNC machines are essential in modern manufacturing, offering precise and efficient control over machining operations. Their working mechanism combines advanced software, precise mechanical components, and automated control systems to produce complex parts with high accuracy and repeatability.

1. Computer Control and Programming

The operation of a high-accuracy CNC machine begins with programming. Engineers or operators create detailed instructions using CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing) software. These instructions, often in the form of G-code, define the movements, speeds, and paths that the machine will follow. The CNC controller interprets these instructions and coordinates the motion of the machine’s components, ensuring that every cut, drill, or milling operation is carried out precisely according to the design.

2. Mechanical Movement and Precision

Once programmed, the CNC machine moves its components with high precision using linear guides, ball screws, and servo motors. These components control the position of the workpiece and the cutting tool along multiple axes, often including X, Y, Z, and rotational axes. Feedback systems, such as encoders, monitor the actual position of each axis and adjust movements in real-time to maintain exact alignment and accuracy. This precise mechanical movement is what allows the machine to achieve tight tolerances and consistent results.

3. Material Removal and Finishing

During the machining process, the cutting tool interacts with the material to remove excess portions according to the programmed design. The machine’s high accuracy ensures smooth cuts, consistent dimensions, and fine surface finishes. Cooling systems, tool changers, and sensors further enhance efficiency and maintain quality throughout the operation.

The transmission adopts the linear rolling guideway imported from Taiwan to meet the requirements of high speed and high efficiency, reduce the friction resistance and temperature rise deformation, improve the machining accuracy, and ensure the long-term stability of the machining accuracy.
In the design of the CNC lathe, the bearing of the spindle box adopts double row cylindrical roller bearing with high rigidity, and the heat dissipation adopts measures to reduce the thermal deformation of the spindle so that the relative stability of the spindle axis can be maintained when the spindle works for a long time.
