When evaluating a woodworking milling machine, prioritize the spindle speed (RPM), as high-speed precision is essential for clean cuts in different wood densities. Ensure the machine features a high-rigidity cast iron table to minimize vibration. For CNC-integrated models, verify the positioning accuracy (typically ±0.02mm) and the compatibility of the control system (e.g., Syntec or DSP) with your existing CAD/CAM software. Additionally, check the motor power (kW) to ensure it meets your production volume requirements.
