Overview

The DMG Mori DMU 50 is a compact simultaneous 5-axis machining center of the type most shops buy as their first true 5-axis machine. Travels are 650 mm (25.6 in) in X, 520 mm (20.5 in) in Y and 475 mm (18.7 in) in Z, over a swivelling rotary table taking workpieces to 630 mm (24.8 in) in diameter and 600 mm (23.6 in) high at up to 300 kg (661.4 lb).

The 300 kg limit is the figure to design fixtures against. It is generous relative to the machine's size and allows real steel workholding rather than restricting the machine to light aluminum fixtures, but on a part approaching 630 mm in diameter it will be reached by the fixture alone if the fixture is not planned for weight.

The B-axis swivels from -35° to +110°. The negative tilt is the part that matters in practice: being able to lean the table past horizontal in the negative direction opens up undercut geometry and side features that would otherwise require the part to be re-fixtured, which is exactly the work a shop buys a 5-axis machine to eliminate.

Spindle choice spans a wide range. The standard is 15,000 rpm at 21 kW (28.2 hp) and 111 Nm (81.9 ft-lb) — a balanced specification for mixed aluminum and steel work. A 46 kW (61.7 hp), 200 Nm (147.5 ft-lb) option nearly doubles power and torque for shops roughing hard material. A 20,000 rpm spindle offers 35 kW (46.9 hp) and 130 Nm (95.9 ft-lb), pairing high speed with more power than the standard unit for small-tool work at high surface speeds. These are meaningfully different machines behind the same model name, and the choice should follow the dominant material rather than the occasional job.

The magazine starts at 30 pockets with 60, 120 or 180 available. On a machine that finishes parts in one setup, the larger options earn their cost quickly, since a single complex part can consume 30 pockets on its own and leave nothing loaded for the next job.

Control is CELOS X with SIEMENS SINUMERIK ONE, CELOS X with HEIDENHAIN, or MAPPS Fanuc. The DMU 50 suits job shops, tool rooms and medical and aerospace subcontractors moving from positional to simultaneous 5-axis work.

Strengths & Limitations

Strengths

300 kg (661.4 lb) workpiece capacity is generous for the machine's size and allows real steel workholding rather than light aluminum fixtures only
B-axis swivelling from -35° to +110° leans the table past horizontal in the negative direction, opening undercut geometry that would otherwise need re-fixturing
Workpieces to 630 mm (24.8 in) diameter and 600 mm (23.6 in) high on travels of 650 × 520 × 475 mm
Spindle range spans a 15,000 rpm standard at 21 kW (28.2 hp) and 111 Nm, a 46 kW (61.7 hp) / 200 Nm option, and a 20,000 rpm unit at 35 kW (46.9 hp) and 130 Nm
Magazine starts at 30 pockets with 60, 120 or 180 available for one-setup work
Control choice of CELOS X with SIEMENS SINUMERIK ONE, CELOS X with HEIDENHAIN, or MAPPS Fanuc

Limitations

The 300 kg workpiece limit is reached by the fixture alone on a part approaching 630 mm in diameter if fixture weight is not planned for
Z travel of 475 mm (18.7 in) is the tightest linear axis against a 600 mm maximum workpiece height
The standard 30-pocket magazine can be consumed by a single complex part, leaving nothing loaded for the next job
Spindle options behave like meaningfully different machines behind one model name, so the choice has to follow the dominant material rather than the occasional job

Best For

Job shops and tool rooms moving from positional to simultaneous 5-axis work Medical and aerospace subcontractors machining complex parts in one setup Mixed aluminum and steel work on the balanced 15,000 rpm / 21 kW standard spindle Parts with undercut and side geometry that use the negative B-axis tilt Steel-fixtured components within the 300 kg workpiece allowance

Frequently Asked Questions

01 What size workpiece does the DMU 50 accept?

Up to 630 mm (24.8 in) in diameter and 600 mm (23.6 in) high at a maximum of 300 kg (661.4 lb), on travels of 650 mm (25.6 in) in X, 520 mm (20.5 in) in Y and 475 mm (18.7 in) in Z. The 300 kg limit is the figure to design fixtures against, since on a part near 630 mm diameter the fixture alone can absorb it.

02 Which spindle should be specified?

The standard is 15,000 rpm at 21 kW (28.2 hp) and 111 Nm (81.9 ft-lb), a balanced choice for mixed aluminum and steel. A 46 kW (61.7 hp), 200 Nm (147.5 ft-lb) option nearly doubles power and torque for roughing hard material. A 20,000 rpm spindle gives 35 kW (46.9 hp) and 130 Nm (95.9 ft-lb) for small-tool work at high surface speed. These are meaningfully different machines behind the same model name.

03 How much does the B-axis range matter?

It is one of the machine's more useful specifications. The B-axis swivels from -35° to +110°, and the negative tilt is the part that counts in practice: leaning the table past horizontal opens up undercut geometry and side features that would otherwise require the part to be re-fixtured — exactly the work a shop buys a 5-axis machine to eliminate.

04 Is the standard tool magazine large enough?

Often not, on a machine that finishes parts in one setup. Capacity starts at 30 pockets with 60, 120 or 180 available. A single complex part can consume 30 pockets on its own and leave nothing loaded for the next job, so the larger options tend to earn their cost quickly in a high-mix shop.

05 What control options are offered?

CELOS X with SIEMENS (SINUMERIK ONE), CELOS X with HEIDENHAIN, or MAPPS Fanuc. The practical consideration is usually consistency with the rest of the shop floor and with existing CAM post-processors rather than any capability difference on this machine.
