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 DMU 125 monoBLOCK is a 5-axis machining center with 1,335 mm (52.6 in) of X, 1,250 mm (49.2 in) of Y and 900 mm (35.4 in) of Z travel. Its workpiece limits are 1,400 mm (55.1 in) in diameter, 790 mm (31.1 in) in height and 2,600 kg (5,732 lb), and DMG MORI states unrestricted crane loading of up to 5,732 lb.

Two neighbours frame it. The DMU 105 monoBLOCK, one size down, travels 1,135 × 1,050 × 750 mm (44.7 × 41.3 × 29.5 in), so the DMU 125 monoBLOCK is larger in every axis. The DMU 125 P duoBLOCK has 1,250 mm (49.2 in) in X and Y and 1,000 mm (39.4 in) in Z, which makes the DMU 125 monoBLOCK the longer machine in X and the shorter one in Z. A shop with long or wide plates and flat bodies gets more from the monoBLOCK; tall work favours the other design.

Handling is a theme of DMG MORI's description. The door opening is printed as 1,900, without a unit, crane loading is unrestricted, and the machine is set up on a three-point support. With parts of up to 2,600 kg this decides how quickly a job is changed over.

The cutting side is given as limits only: a spindle range with up to 30,000 rpm or with up to 317 ft lb, and machine-integrated tool magazines with up to 180 pockets. Which spindle and which magazine the base machine has is not stated.

The frame is one casting with a one-piece column, 2.2 in. roller guideways in all axes and ball screws listed as ø 50 / 63 / 50, and the swivelling rotary table is clamped. Cooling measures, a high-performance coolant unit and multi-sensor compensation are standard, while 25 % higher precision comes with the optional precision package.

Frequently Asked Questions

01 DMU 125 monoBLOCK or DMU 125 P duoBLOCK: which has more travel?

It depends on the axis. The DMU 125 monoBLOCK has 1,335 mm (52.6 in) of X, 1,250 mm (49.2 in) of Y and 900 mm (35.4 in) of Z. The DMU 125 P duoBLOCK has 1,250 mm (49.2 in) of X, 1,250 mm (49.2 in) of Y and 1,000 mm (39.4 in) of Z. The monoBLOCK is longer in X, the duoBLOCK deeper in Z.

02 How big is the step up from the DMU 105 monoBLOCK?

The DMU 105 monoBLOCK travels 1,135 mm (44.7 in) in X, 1,050 mm (41.3 in) in Y and 750 mm (29.5 in) in Z. The DMU 125 monoBLOCK travels 1,335 mm (52.6 in), 1,250 mm (49.2 in) and 900 mm (35.4 in), so it is the larger machine in all three axes.

03 How are heavy parts loaded into the DMU 125 monoBLOCK?

By crane. DMG MORI states unrestricted crane loading of up to 5,732 lb, which matches the 2,600 kg (5,732 lb) maximum workpiece weight. The door opening is listed as 1,900 with no unit printed, so confirm the clear opening against the widest part or fixture you plan to lift in.

04 Which spindle speeds are available?

DMG MORI describes a spindle range with up to 30,000 rpm or with up to 317 ft lb. Those are the two ends of the range and belong to different spindles. The listed data names no standard spindle and gives no power figure, so the spindle has to be specified on the quotation.

05 Can the DMU 125 monoBLOCK be used for turning?

Turning is a matter of the table. Among the table solutions for this size DMG MORI lists one for complete machining with milling and turning with up to 3,983 ft lb, which is the DMU 125 FD monoBLOCK. The 5-axis machining table is listed for up to 5,732 lb.
