There are workpieces that can only be machined on truly large machines. It's hard to believe the giants that exist, for example, to shape ship engines or components for wind turbines. When looking at the market, five machines stand out that essentially break all records...

1st Place: Waldrichsiegen with the Profimill 3

With the portal milling machine Profimill 3 from Waldrichsiegen, workpieces weighing up to 500 tons (approx. 1.1 million lbs) can be processed, according to the datasheet. It achieves a maximum torque of 11,000 newton meters (approx. 8,113 lb-ft). The width of a workpiece can reach 14 meters (approx. 46 feet), and the height 12 meters s (approx. 39 feet), as Waldrichsiegen informs. With a working space of well over 7,000 cubic meters (approx. 247,000 cu ft), one could practically live inside it. However, its installation requires significant preparation, such as creating a sufficiently load-bearing foundation in the factory hall. It is considered extremely robust in design, and the model is based on a modular concept. The spindle head (RAM) is hydrostatically guided and features a relatively thick-walled housing, which, according to the manufacturer, reliably helps prevent interference and vibrations. It is essentially configured individually for each user. Its areas of expertise include energy technology, large engines, forged and cast parts, as well as heavy and special machine construction.

2nd Place: Starrag's Droop+Rein Fogs HD Series

The Fogs HD belongs to the high-gantry machines by Starrag from Switzerland. Its clamping plates can be offered up to 30 meters (approx. 98 feet) in length if required, with a width of up to 5 meters (approx. 16.4 feet). The drive power reaches up to 100 kilowatts (134 hp), and the torque achieves a maximum of 7,500 newton meters (approx. 5,530 lb-ft). Its sliding milling unit is thermosymmetrically designed, and there are selectable, exchangeable milling heads, various spindles, and NC controls available. Tooling and clamping can take place while another part is being processed. The application areas are as follows: tool and mold making, titanium machining for aircraft parts, and general mechanical engineering.

3rd Place: Waldrich Coburg with the Powertec-Gantry

The second-largest milling machine in the world also carries the name Waldrich. It is based on a modular design. However, as the manufacturer emphasizes, it can be offered either as a gantry (portal) or a table system. The maximum spindle power is specified at 130 kilowatts (174 hp). In its largest variant, it can process components up to 10 meters (approx. 33 feet) in width and 10 meters (approx. 33 feet) in height. The clamping length is measured at over 2.5 meters (approx. 8.2 feet). It is available with either a fixed or height-adjustable crossbeam. Application fields include engine manufacturing (diesel), the power plant and turbine sector, as well as general mechanical engineering.

4th Place: DMG Mori with the DMF Traveling Column Machines

The DMF traveling column machines from DMG Mori are designed for precise 5-axis precision machining of long structural components and complex workpieces. With the newest model, the DMF 600|11, the series expands to include an option for XXL machining. Components measuring up to 6,000 × 1,100 × 1,050 millimeters (approx. 236 × 43 × 41 inches) and weighing 12 tons (approx. 26,450 lbs) can fit in its workspace. An optional partition divides the workspace into two areas with dimensions of 3,600 × 1,100 × 1,050 millimeters (approx. 141 × 43 × 41 inches), each allowing independent configurations with A- or C-axes. The rotary tables can handle loads of up to two tons and enable 5-axis machining of workpieces with a maximum diameter of 1,400 millimeters (approx. 55 inches) and a height of 1,050 millimeters (approx. 41 inches). The DMF traveling column machines from DMG MORI stand for maximum efficiency in 5-axis precision machining of long structural components and other complex workpieces. Speedmaster spindles with speeds of up to 20,000 rpm are used for precision milling, while Powermaster spindles with a torque of up to 430 nanometers (approx. 317 lb-ft) are recommended for heavy machining of demanding materials.
