High-power spindle and all-metal body: This 3020 PLUS CNC body has a solid structure, built-in all-metal body structure, and upgraded 500W 52mm spindle and E11 collet, which is more powerful and efficient, and can cut stainless steel, aluminum and other metals High precision and stability: It does not contain any plastic parts. The CNC router is equipped with solid double-steel linear guide rail with a thickness of 12mm and bearing slide rail. The all-metal X-Z axis part has a vertical stroke of up to 70mm, and the stepping motor is more powerful. All these are to ensure that the movement of the 3-axis is faster and more stable, thus improving the carving accuracy Larger work area: The work area of the 3020-PLUS router is larger than that of the 3018-PRO, increasing to 300 x 200 x 70mm).
