industrial cnc machine 3d model

A large heavy-duty industrial machine tool, massive CNC manufacturing equipment, hard-surface mechanical structure, solid heavy base, enclosed and semi-open body shell, clear linear rails, vertical columns, worktable, machining chamber, and structural frame. Precise, clean, symmetrical industrial design, like a real high-end factory machine prototype. Light gray and white metal housing with a few dark mechanical parts, no brand, no text, no logo, no stickers. Emphasize industrial mockup style, 3D CAD prototype, hard-surface, clean topology, precise mechanical design, realistic manufacturing equipment, heavy-duty CNC machine, large-scale machine tool, studio lighting, minimal background.
