Промпт: 3D CAD render of a massive custom-built heavy-duty DIY metal milling machine. The machine base is 2 meters long and 1 meter wide, constructed from thick steel U-channels (schwellers) welded in a rigid frame with a zig-zag internal truss pattern at 45 degrees. The top of the base is covered with a thick 10mm steel plate. On top of the plate, two huge, solid chrome-plated 100mm diameter hydraulic shafts are bolted down as linear guide rails running along the entire 2-meter length. A heavy rectangular work table is mounted on these shafts using open-type bronze slide bushings. A massive 40mm thick ballscrew (SFU4005) runs down the center of the bed to move the table. In the middle of the base, a towering vertical column made of double U-channels welded into a rigid box shape rises 1.4 meters high. The column is securely bolted to the side of the bed and reinforced by four heavy 45-degree angle steel struts (two on each side). A rigid milling head with a low-speed industrial spindle is tightly bolted to the front face of the column. Industrial workshop background, clean engineering design, highly detailed mechanical components, photorealistic. Ver más
