CNC Machine Design Components When designing a CNC machine for processing lightweight metals and wood, both machining capacity and precision are crucial. Here are the fundamental factors and recommendations to consider: 1. Machine Frame and Chassis Material : Steel, aluminum, or high-strength alloys should be used. While a sturdy structure is essential for lightweight metals, precision and vibration control are critical when working with wood. Reason : Lightweight metals require greater rigidity and strength. On the other hand, wood processing might be negatively impacted by an overly rigid structure due to increased sensitivity to vibrations. Proper material selection ensures balance.     2. Spindle Selection Power : Opt for a spindle motor between 1.5 kW and 3 kW. Adjustable spindle speeds are crucial. Reason : Higher RPMs are more effective for wood, while lower speeds are ideal for lightweight metals. Adjustable speeds allow processing different materials on the sam...
