This machine combines advanced CNC technology with dual-station parallel processing capabilities, greatly improving production efficiency and machining accuracy. It is widely used in aerospace, automotive manufacturing, mold processing, electronic equipment, and precision parts industries.

[0003] The dual-head CNC milling machine uses a built-in computer numerical control (CNC) system to receive and parse machining instructions generated by CAD / CAM software, controlling two independent milling heads to perform precise slot milling operations on the workpiece synchronously or asynchronously. Each milling head can independently adjust its spindle speed, feed rate, and depth of cut, ensuring efficient and stable machining results on workpieces of different materials and shapes.

[0004] Traditional milling machines are woodworking milling machines, which require manual pushing of the workpiece to process it slowly, resulting in low efficiency and safety issues. Utility Model Content
