WFL’s M80-G Millturn features a counter spindle and is available with distances between centers measuring 2,000, 3,000, 4,500 or 6,000 mm. Offering milling power ranging to 58 kW, the turn-mill is well-suited for applications such as six-sided machining of chuck-held and shaft components ranging to 1,000 mm in diameter. When combined with a revolver or other machining unit, work can be performed in parallel on both main spindles.
The counter spindle has the same spindle and bearing dimensions as the left-hand spindle box to enable identical machining performance on both spindles, the company says. Heavy roughing is also possible on the counter spindle, which is equipped with a 40-kW (S1) drive. A 60-kW (S1) drive is available as an option. According to the company, both spindles have identical thermal characteristics due to similar design and structure as well as short distances from the turning center to the bed base. The bed guide features a configuration of fixed-swarf and other guides to enable minimum positioning distances between the various slides on the lower guide rail. The machine is controlled by Siemens’ Sinumeric 840D Solution Line in combination with Sinamic drives.
The tool magazine is easily accessible from the front and features a stable, compact design. The tool shuttle with rack-and-pinion drive is equipped with linear axes to avoid rotation-induced centrifugal effects and can accommodate tools as long as 900 mm and weighing as much as 35 kg. For heavy-duty internal machining, a 2x pick-up magazine is available for accommodating tools as long as 1,700 mm, while a 15x heavy boring bar magazine accommodates tools as long as 2,500 mm.
