en.Wedoany.com Reported - The world's largest cutting machine tools ranking has been unveiled, with the Waldrichsiegen Profimill 3 gantry milling machine taking the top spot for its ability to process workpieces weighing up to 500 tons. In the field of metal cutting, when workpiece dimensions far exceed the processing range of conventional equipment, these giant machines become irreplaceable production tools, widely used in the machining of large components such as marine engines and wind power generators.
Topping the list is Waldrichsiegen's Profimill 3 gantry milling machine, capable of processing workpieces weighing up to 500 tons, with a maximum torque of 11,000 Newton meters. According to Waldrichsiegen, it can handle workpieces up to 14 meters wide and 12 meters high, with a processing space exceeding 7,000 cubic meters. The machine adopts a modular concept design, with the ram (RAM) equipped with hydrostatic guides and thick-walled housing, helping to avoid interference and vibration. The equipment can be individually configured according to user requirements, primarily applied in energy technology, large engines, forgings and castings, as well as heavy special machinery manufacturing. Installing such equipment requires pre-building a dedicated load-bearing foundation in the workshop.
Ranked second is the Swiss company Starrag's Droop+Rein Fogs HD series overhead gantry machine. Its clamping plate length can be provided up to 30 meters and width up to 5 meters as needed. The equipment has a drive power of up to 100 kW and a maximum torque of 7,500 Newton meters. The ram milling unit features a thermally symmetrical structure design, with options for interchangeable milling heads, multiple spindles, and CNC systems. The machine supports setup and clamping operations while machining one part, primarily applied in mold making, titanium alloy processing for aircraft parts, and general mechanical manufacturing.
Third place goes to Waldrich Coburg's Powertec gantry milling machine. This equipment is also based on a modular structure and can be provided as a gantry or table system. It has a maximum spindle power of 130 kW, can process components up to 10 meters wide and 10 meters high, with a clamping length exceeding 2.5 meters. Users can opt for a fixed or height-adjustable crossbeam, primarily applied in diesel engine manufacturing, power plants and turbine fields, as well as general mechanical manufacturing.
Ranked fourth is DMG Mori's DMF moving column machine series, characterized by five-axis precision machining of long structural parts and complex workpieces. DMG Mori states that this series achieves maximum efficiency in five-axis precision machining of long structural parts and other complex workpieces. The latest model, DMF 600|11, can accommodate components up to 6,000 × 1,100 × 1,050 mm in size and weighing up to 12 tons. An optional partition can divide it into two independent zones, each measuring 3,600 × 1,100 × 1,050 mm, and can be independently configured with an A-axis or C-axis. The rotary table can carry a load of two tons, processing workpieces with a maximum diameter of 1,400 mm and height of 1,050 mm. The machine offers the Speedmaster spindle (20,000 rpm, suitable for precision milling) and the Powermaster spindle (430 Nm torque, suitable for heavy cutting of difficult-to-machine materials).
