How much does the DMG Mori DMF 300|11 cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from DMG Mori. Configuration moves it a long way.
Overview
The DMG MORI DMF 300|11 is the larger of the two DMF cross-sections offered with 3,000 mm of X travel: 3,000 × 1,100 × 1,050 mm (118.1 × 43.3 × 41.3 in), with a workpiece limit of 3,600 mm (141.7 in) in length, 1,100 mm (43.3 in) in width and height, and 6,000 kg (13,227.7 lb). Against the DMF 300|8 FD, which has 800 mm (31.5 in) of Y and 850 mm (33.5 in) of Z on the same X, that is about 38% more Y and about 24% more Z.
The bigger frame brings a wider spindle range. DMG MORI lists spindles from 12,000 to 20,000 rpm and up to 430 Nm, with tool interfaces named as SK40 / HSK-A63 and SK50 / HSK-A100. A larger interface is normally what carries big face mills, long boring bars and high torque, but the listed data does not say which speed or torque goes with which interface. Tool length follows the interface: up to 400 mm in general, 540 mm with HSK-A100. The magazine goes up to 120 pockets and the tool change takes place outside the working area.
Axis drives are described as helical toothed belts with ground ball screws in all axes, and the cooling measures include internally cooled ball screws. A screw that is cooled from inside grows less as it warms up over a shift, which matters most on the 3,000 mm X axis. The dynamic package, with a linear drive in X and higher acceleration and feed rate in X, Y and Z, is an option.
As delivered the machine works in 4 axes with the B-axis. A rotary table for 5-axis machining is optional, and the listed maximum workpiece diameter is 1,400 mm (55.1 in). The bed is a single cast iron piece with 3 linear guideways in X and constant overhang over the complete working area.

Strengths & Limitations
Strengths
- Spindle range from 12,000 to 20,000 rpm and up to 430 Nm, with SK40 / HSK-A63 or SK50 / HSK-A100 interfaces
- 1,100 mm (43.3 in) of Y and 1,050 mm (41.3 in) of Z travel on 3,000 mm (118.1 in) of X
- Carries workpieces up to 6,000 kg (13,227.7 lb) and 3,600 mm (141.7 in) long
- Tools up to 540 mm long with HSK-A100, 400 mm otherwise
- Internally cooled ball screws are part of the listed cooling measures
- Ground ball screws with helical toothed belts in all axes
Limitations
- The 430 Nm and 20,000 rpm figures are the two ends of a spindle range and do not describe one spindle
- 5-axis machining requires the optional rotary table; the standard machine is 4-axis with the B-axis
- A linear drive in X is only available with the optional dynamic package
- Spindle power is not stated in DMG MORI's listed figures

Frequently Asked Questions
01
DMG MORI names SK40 / HSK-A63 and SK50 / HSK-A100. The spindle range runs from 12,000 to 20,000 rpm and up to 430 Nm. The listed data does not match each speed and torque to an interface, so confirm the speed, torque and power of the spindle you are quoted.
02
Up to 400 mm, or 540 mm with HSK-A100. The tool magazine has up to 120 pockets, and tools are changed outside the working area, which DMG MORI describes as collision free.
03
X travel is the same 3,000 mm (118.1 in). The DMF 300|11 has 1,100 mm (43.3 in) of Y and 1,050 mm (41.3 in) of Z, against 800 mm (31.5 in) and 850 mm (33.5 in) on the DMF 300|8 FD. That is about 38% more Y travel and about 24% more Z travel.
04
Up to 6,000 kg (13,227.7 lb). The part can be 3,600 mm (141.7 in) long, 1,100 mm (43.3 in) wide and 1,100 mm (43.3 in) high. For rotating parts the listed maximum diameter is 1,400 mm (55.1 in).
05
Helical toothed belts and ground ball screws in all axes, according to DMG MORI's Highlights, with internally cooled ball screws among the cooling measures. A linear drive in the X-axis is offered as part of an optional dynamic package that also raises acceleration and feed rate in X, Y and Z.
