4. Drive System

• Yaskawa Servo Motors: The machine includes six 1300W Yaskawa servo motors in total. The X and Z axes each use one servo motor, while the Y-axis and the eight rotary axes are driven by two servo motors each. Yaskawa servo motors provide higher positioning accuracy and response speed, offering over 30% higher rotational speed than standard servos and start/stop acceleration times ≤0.1s. The drives incorporate overload, overvoltage, overcurrent, and overheating protection, effectively handling instantaneous load impacts during multi-station router operation. With higher protection ratings and industrial-grade durability, they prevent ingress of wood chips and debris during processing, withstand high-temperature and humid environments, and support 24 hour continuous operation.
• Shimpo Planetary Reducers: The X and Y-axis servo motors are paired with Japanese Shimpo planetary gear reducers. Their internal helical gear design effectively reduces operating noise compared to spur gears. The planetary reducers enhance the machine's load adaptability and torque output, with strong overload and impact resistance, enabling the machine to withstand higher radial and axial forces. Suitable for heavy-duty applications, they ensure high repeatability positioning accuracy and motion performance, fully leveraging the servo system's advantages for optimal performance in multi-station CNC routers.

5. High-Precision Transmission System

• Linear Guideways/Bearings: Utilize HIWIN heavy-duty linear guides and bearings from Taiwan, with a four-row single-arc groove contact structure that provides over 30% higher rigidity than same-size alternatives. Low friction coefficient and no-slip operation ensure machining accuracy.
• Helical Racks: Fitted with YYC helical racks, offering larger meshing contact area for smooth transmission, low noise, minimal vibration, and higher torque capacity. Effectively improves machine speed, stability, and service life.
• Ball Screws: Employ TBI ball screws from Taiwan, with transmission efficiency exceeding 90% and drive torque only one-third that of sliding screws. Preloading eliminates axial clearance, achieving extremely high positioning accuracy.

6. 4-Axis Control System
