H. H. Roberts TW-31-Q CNC BED MILL VERTICAL MACHINING CENTER

This vertical machining center features a robust table measuring 42.000 inches in length by 13.000 inches in width, capable of supporting workpieces up to 1,200 lbs. An optional index or rotary table can be added for enhanced versatility. The vertical spindle utilizes a #40 taper, with a maximum speed of 6,000 RPM (optional 4,500 RPM) and a 30-minute power rating of 7.5 HP (optional 12 HP), ensuring efficient material removal and precision for a wide range of applications. The machine is equipped with a manual tool carrier and offers optional pallet changing with up to two pallets, increasing productivity for batch operations. It operates on three primary axes (X, Y, Z), with an optional fourth axis for expanded machining capabilities. Axis travels are 31.000 inches (X), 20.000 inches (Y), and 20.000 inches (Z), with an optional Z-axis extension to 24.000 inches. Maximum feed rates for all axes are 400 inches per minute, while rapid traverse reaches 600 inches per minute, enabling fast and accurate positioning. The machine’s design supports high-speed, high-precision milling, making it suitable for demanding production environments and complex part geometries.
