Our best estimate for the DMG Mori DMU 20 Linear is $350,000 - $500,000. This is an estimate for a 5-axis machining centers in this class, not a quote from DMG Mori; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/dmg-mori-dmu-20-linear#price; the request is passed to DMG Mori or an authorised dealer.
Up to 220 mm (8.7 in) in diameter and 283 mm (11.1 in) in height, with a maximum weight of 15 kg (33.1 lb). The travels are 220 mm (8.7 in) in X, 370 mm (14.6 in) in Y and 290 mm (11.4 in) in Z.
DMG MORI lists high-frequency spindles from FISCHER with a maximum of 60,000 rpm. An HSK-32 spindle is standard. Options are an HSK-32 spindle that reaches the 60,000 rpm maximum and two HSK-40 spindles, one of which is also available with shaft cooling and one of which is lifetime grease lubricated.
DMG MORI states 3 µm positioning accuracy as standard and attributes it to wider linear guides. The other measures listed are a cast bed optimised by FEM for long-term stability, temperature management and a gantry design with a thermally symmetric layout.
The A-axis has a swivel range of +130° to -93° with a maximum table load of 33 lb. The C-axis turns at 150 rpm in the standard version, and a 1,500 rpm C-axis is optional.
Among the nearby models, the DMU 40 eVo has travels of 400 × 400 × 375 mm (15.7 × 15.7 × 14.8 in), against 220 × 370 × 290 mm (8.7 × 14.6 × 11.4 in) on the DMU 20 linear. It is the step to take when parts outgrow the 220 mm diameter limit.
