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

With 800 mm (31.5 in) of X travel, the DMG MORI DMX 80 u is the longer of the two DMX U machines. Y is 600 mm (23.6 in) and Z is 510 mm (20.1 in), the same as on the DMX 60 U, which has 600 mm (23.6 in) of X. The swivel-rotary table takes workpieces up to 800 mm (31.5 in) in diameter, 450 mm (17.7 in) high and 350 kg (771.6 lb).

The envelope is wider than it is deep, and that shapes what the machine does well. A long part or a row of vises lies along X with the table level. A round part at the full 800 mm diameter is wider than the 600 mm of Y, so its outer features are reached by rotating the C axis, not by travelling to them. Part height of 450 mm sits inside the 510 mm of Z, but tool length and the swivel of the table both eat into that margin.

DMG MORI lists 9 T-slots on the table and points to access for the operator and for a crane, which fits a load limit of 350 kg. The bed is monolithic, with wide roller guideways in all axes and up to 50% higher static rigidity than the predecessor model.

All linear axes rapid at 42 m per minute. X and Y have direct drive transmission, and every linear axis has a linear scale as part of a direct measuring system. Thermal compensation uses several sensors. For contouring quality DMG MORI quotes circular interpolation at below 6 µm on the Double Ballbar in all planes.

The spindle range is described as reaching 20,000 rpm, with a High Torque version of 200 Nm as the alternative for heavier cuts. In the same X travel class, the DMU 80 eVo is listed with 800 × 650 × 550 mm (31.5 × 25.6 × 21.7 in).

Strengths & Limitations

Strengths

800 mm (31.5 in) of X travel with a swivel-rotary table for workpieces up to 350 kg (771.6 lb)
9 T-slots on the table for clamping devices, with access for a crane
Direct drive transmission in the X and Y axes and 42 m per minute rapid traverse in all linear axes
Double Ballbar result below 6 µm in all planes for circular interpolation
Multisensor thermal compensation and linear scales in all linear axes
Monolithic machine bed with up to 50% higher static rigidity than the predecessor

Limitations

Y travel of 600 mm (23.6 in) is less than the 800 mm (31.5 in) workpiece diameter, so large round parts depend on table rotation for full coverage
No spindle power is listed, and the 200 Nm High Torque version comes without a stated speed
The number of tool places in the magazine is not stated
Workpiece height stops at 450 mm (17.7 in), so the capacity gained with 800 mm (31.5 in) of X is in length, not in height

Best For

Long parts and multi-vise setups along 800 mm (31.5 in) of X Round workpieces up to 800 mm (31.5 in) in diameter machined on five sides Parts and fixtures up to 350 kg (771.6 lb) that need a crane to load Contoured work that benefits from direct drives in X and Y Tough materials cut with the 200 Nm High Torque spindle

Frequently Asked Questions

01 How much bigger is the DMX 80 u than the DMX 60 U?

The DMX 80 u has 800 mm (31.5 in) of X travel where the DMX 60 U has 600 mm (23.6 in). Both share 600 mm (23.6 in) of Y and 510 mm (20.1 in) of Z. On the DMX 80 u the workpiece can be up to 800 mm (31.5 in) in diameter and 350 kg (771.6 lb), and the table has 9 T-slots.

02 Can the DMX 80 u machine a full 800 mm diameter part?

It can hold one: the maximum workpiece diameter is 800 mm (31.5 in) and the height limit is 450 mm (17.7 in). X travel matches the diameter, but Y travel is 600 mm (23.6 in), so features near the rim have to be turned towards the spindle with the rotary axis. Check the reach for your part before relying on the full diameter.

03 What spindle options does the DMX 80 u have?

DMG MORI describes a full range of available spindles up to 20,000 rpm, or a High Torque version with 200 Nm. Neither power nor tool interface is listed, and the speed of the High Torque version is not given either, so ask for the data of each spindle before choosing.

04 What measuring and compensation systems are fitted?

A direct measuring system with linear scales in all linear axes, plus multisensor thermal compensation. X and Y are moved by direct drive transmission. DMG MORI states an improved accuracy of circular interpolation, with a Double Ballbar result below 6 µm in all planes. No positioning accuracy value is listed.

05 How does the DMX 80 u compare with the DMU 80 eVo?

Both have 800 mm (31.5 in) of X. The DMU 80 eVo is listed with 650 mm (25.6 in) of Y and 550 mm (21.7 in) of Z, slightly more than the 600 mm (23.6 in) and 510 mm (20.1 in) of the DMX 80 u. The DMX 80 u's own data gives a 350 kg (771.6 lb) workpiece limit and 42 m per minute rapids.
