How much does the DMG Mori DMU 40 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 DMU 40 is a 5-axis machining center with a swivel rotary table, offered in three machine types that differ mainly in the spindle. All share travels of 550 × 450 × 420 mm (21.7 × 17.7 × 16.5 in) and a workpiece limit of 505 mm (19.9 in) in diameter, 570 mm (22.4 in) in height and 300 kg (661.4 lb).
The base DMU 40 has an inline spindle with 12,000 rpm, 15 kW and 95 Nm. The DMU 40 PLUS has an inlineMASTER spindle with 15,000 rpm and 121 Nm. The DMU 40 PRO has a speedMASTER spindle with 20,000 rpm, 32 kW and 130 Nm. Torque rises only moderately from type to type while speed and, on the PRO, power rise a great deal: the PRO has more than twice the power of the base machine. So the step up pays off in aluminium and in finishing with small tools, less so in low-speed roughing.
The types also differ in how much is done for thermal stability and measurement. A comprehensive cooling concept is listed for the DMU 40 PLUS and PRO, and the direct absolute path measuring system in all linear axes is optional on the base DMU 40. A buyer comparing a base machine with a PLUS should put those two items next to the spindle data. Common to the types are a single-piece cast iron bed, directly driven ball screws in X and Y and cooled table bearings.
Floor space is the other argument. DMG MORI gives a footprint of 5.05 m² and a machine width under 2.00 m, and says the footprint stays compact in connection with an automation system. The table swivels on the B-axis from -35° to +110° and loads up to 300 kg. The DMU 50 is the next size, with 650 × 520 × 475 mm (25.6 × 20.5 × 18.7 in) of travel.

Strengths & Limitations
Strengths
- Three machine types on one frame: 12,000 rpm inline spindle, 15,000 rpm inlineMASTER or 20,000 rpm speedMASTER
- The DMU 40 PRO spindle delivers 32 kW and 130 Nm at up to 20,000 rpm
- Footprint of 5.05 m² with a machine width under 2.00 m
- B-axis swivel range of -35° to +110° with a loading weight of up to 300 kg (661.4 lb)
- Single-piece cast iron machine bed and directly driven ball screws in X and Y
- Cooled table bearings on the swivel rotary table
Limitations
- The base DMU 40 spindle stops at 12,000 rpm with 15 kW and 95 Nm
- Direct absolute path measuring in all linear axes is optional on the base DMU 40
- The comprehensive cooling concept is listed for the DMU 40 PLUS and PRO, not for the base type
- Even the DMU 40 PRO offers 130 Nm at most, so heavy roughing in steel is limited on every type
- No tool magazine capacity is stated in DMG MORI's listed figures for this model

Frequently Asked Questions
01
Chiefly the spindle. The DMU 40 has an inline spindle with 12,000 rpm, 15 kW and 95 Nm. The DMU 40 PLUS has an inlineMASTER with 15,000 rpm and 121 Nm. The DMU 40 PRO has a speedMASTER with 20,000 rpm, 32 kW and 130 Nm. The comprehensive cooling concept is listed for PLUS and PRO, and the direct absolute path measuring system is optional on the base DMU 40.
02
Travels are 550 mm (21.7 in) in X, 450 mm (17.7 in) in Y and 420 mm (16.5 in) in Z. The workpiece can be up to 505 mm (19.9 in) in diameter and 570 mm (22.4 in) high, and the table takes up to 300 kg (661.4 lb).
03
DMG MORI states a footprint of only 5.05 m² and a machine width of less than 2.00 m. It also says the footprint remains compact in connection with an automation system, though no dimensions are given for that combination.
04
The swivel area of the B-axis is -35° to +110°. The positive end takes the table past its vertical position and the negative end tilts it the other way from level, so features on opposite flanks of a part can be reached without re-clamping. The loading weight is up to 300 kg.
05
By travel, the DMU 40 eVo is smaller at 400 × 400 × 375 mm (15.7 × 15.7 × 14.8 in), the DMU 40 has 550 × 450 × 420 mm (21.7 × 17.7 × 16.5 in) and the DMU 50 is larger at 650 × 520 × 475 mm (25.6 × 20.5 × 18.7 in).
