The 540 CNC milling machine is designed for high-efficiency 8-station processing of copper, iron, aluminum, and stainless steel workpieces within 500mm x 400mm dimensions. Fully compatible with general machining centers, it supports versatile functions including drilling, tapping, milling, and engraving. Utilizing patented high-rigidity and anti-deformation structures, it is ideal for stainless steel parts requiring tapping within 8mm and drilling within 10mm. Its compact footprint allows a single operator to manage multiple units, significantly increasing per-capita output while reducing processing costs.
