How much does the DMG Mori ULTRASONIC 40 eVo linear 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 ULTRASONIC 40 eVo linear is the compact machine among the ULTRASONIC eVo linear models: 400 mm (15.7 in) of travel in X and in Y, 375 mm (14.8 in) in Z, and a swivel rotary table that takes parts up to 480 mm (18.9 in) in diameter, 460 mm (18.1 in) high and 250 kg (551.2 lb).
Those workpiece limits are larger than the travels. A 480 mm part on 400 mm of X and Y, and a 460 mm height on 375 mm of Z, are possible because the B-axis swivels from -5° to +110° and the C-axis rotates the part to the tool. A full-size workpiece is reachable on its faces and periphery, while a feature in the far corner of a tall part should be checked in simulation before the job is accepted. The table load of up to 250 kg is generous for the envelope and leaves room for a substantial fixture.
Three milling spindles are listed. The speedMASTER with 20,000 rpm is the standard version. A speedMASTER with 15,000 rpm and 200 Nm is an option aimed at heavier cuts, and a motorspindle with 24,000 rpm is the option for small tools. For mill-turn operation DMG MORI lists a C-axis speed of up to 1,200 rpm together with a motorspindle with 18,000 rpm, 130 Nm and HSK A63.
The ultrasonic function works through an HSK-A63 / HSK-E50 actuator system with automatic frequency detection, amplitude regulation and automatic feed adjustment, and DMG MORI states up to 50% reduced process forces. Thermal measures are listed in detail: cooling of the table unit with its bearings and drives, cooling of the bearings and spindle nuts of the ball screw drives, and cooled guideways in X, Y and Z. One size up, the ULTRASONIC 60 eVo linear has 750 mm (29.5 in) of X and 550 mm (21.7 in) of Y and Z.

Strengths & Limitations
Strengths
- Takes workpieces up to 480 mm (18.9 in) in diameter and 250 kg (551.2 lb) on 400 mm (15.7 in) of X and Y travel
- speedMASTER spindle with 20,000 rpm in the standard version
- Mill-turn operation with a C-axis speed of up to 1,200 rpm
- B-axis swivel range of -5° to +110° for 5-axis simultaneous machining
- Cooled guideways in X, Y and Z, plus cooling of the table unit, table bearings and drives
- Ultrasonic actuator system for HSK-A63 / HSK-E50 with automatic frequency detection and amplitude regulation
Limitations
- The 200 Nm speedMASTER is an option and is limited to 15,000 rpm
- The 24,000 rpm motorspindle is also an option; the standard speedMASTER runs at 20,000 rpm
- Z travel is 375 mm (14.8 in), less than the 460 mm (18.1 in) maximum workpiece height, so tall parts restrict tool length
- The B-axis swivels only 5° in the negative direction

Frequently Asked Questions
01
The standard version is a speedMASTER with 20,000 rpm. Two options are listed: a speedMASTER with 15,000 rpm and 200 Nm, and a motorspindle with 24,000 rpm. Under mill-turn operation DMG MORI also lists a motorspindle with 18,000 rpm, 130 Nm and HSK A63.
02
DMG MORI lists mill-turn operation for it, with a C-axis speed of up to 1,200 rpm and a motorspindle with 18,000 rpm, 130 Nm and HSK A63. On a table for parts up to 480 mm (18.9 in) in diameter, that speed serves turned features on small and medium diameters.
03
480 mm (18.9 in) in diameter, 460 mm (18.1 in) in height and 250 kg (551.2 lb). Both dimensions exceed the linear travels of 400 mm (15.7 in) in X and Y and 375 mm (14.8 in) in Z, so reach on a full-size part depends on the swivel rotary table and on tool length.
04
Three items appear under accuracy: cooling of the table unit, table bearings and drives; cooling of the bearings and spindle nuts of the ball screw drives; and cooled guideways in the linear axes X, Y and Z. They address the heat sources that move a part out of position during a long cycle.
05
It sits between them. The ULTRASONIC 20 linear has 220 mm (8.7 in), 370 mm (14.6 in) and 290 mm (11.4 in) of travel, and the ULTRASONIC 60 eVo linear has 750 mm (29.5 in), 550 mm (21.7 in) and 550 mm (21.7 in). This machine offers 400 mm (15.7 in) in X and Y and 375 mm (14.8 in) in Z.
