How much does the DMG Mori HSC 55 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 HSC 55 linear is a 5-axis high-speed machining center with direct drives in all axes, 450 × 650 × 460 mm (17.7 × 25.6 × 18.1 in) of travel and a basic HSC spindle of 28,000 rpm with HSK-A63. Workpieces can be up to 500 mm (19.7 in) in diameter, 350 mm (13.8 in) high and 200 kg (440.9 lb).
Two spindles are listed, and choosing between them is really a choice of tooling. The basic version runs at 28,000 rpm on HSK-A63 and can optionally have shaft cooling. The other runs at 40,000 rpm, has shaft cooling and uses HSK-E50. HSK-A63 accepts the larger cutters needed to rough a cavity. HSK-E50 is a smaller interface made for small finishing tools at speed. A shop that roughs and finishes on the same machine will lean towards the 28,000 rpm spindle, and one that only finishes towards 40,000 rpm.
The axes are built for short, rapid moves: 2g acceleration and up to 80 m/min rapid traverse, with water-cooled torque motors in the integrated A / C swivel and rotary axis. DMG MORI ties the machine to surface results of Ra < 0.2 and names the supporting structure: a thermo-symmetrical portal design, lightweight slide units on a solid base frame, and a single piece hybrid mineral cast bed on a 4-point support. No linear guides lie open in the working area, which keeps chips and dust off them.
The tool magazine has 30 places as standard, with 60 or 120 places as options. For automation there is a universal automation table top, which adds 45 mm of installation height in the Z direction, so allow for it against the 350 mm part height. One detail of the envelope: X travel of 450 mm is shorter than the 500 mm workpiece diameter, while Y is the long axis at 650 mm.

Strengths & Limitations
Strengths
- Direct drives in all axes with 2g acceleration and up to 80 m/min rapid traverse
- HSC spindle with 28,000 rpm and HSK-A63 in the basic version, or 40,000 rpm with shaft cooling on HSK-E50
- Single piece hybrid mineral cast bed on a 4-point support in a thermo-symmetrical portal design
- Water-cooled torque motors in the rotary axes of the integrated A / C swivel and rotary unit
- Tool magazine with 30 places as standard, expandable to 60 or 120 places
- No open linear guides in the working area
Limitations
- The 40,000 rpm spindle uses HSK-E50, a smaller interface than the HSK-A63 of the basic spindle, which limits cutter size
- Spindle power and torque are not stated for either spindle
- Workpieces are limited to 200 kg (440.9 lb) and 350 mm (13.8 in) in height
- The 60 and 120 place magazines are options; the standard magazine has 30 places
- The universal automation table top takes 45 mm of installation height in the Z direction

Frequently Asked Questions
01
The basic version is an HSC spindle with 28,000 rpm and HSK-A63, optionally with shaft cooling. The second is an HSC spindle with 40,000 rpm, shaft cooling and HSK-E50. DMG MORI's Highlights give no power or torque for either, so request the spindle curves when the choice depends on roughing ability.
02
Up to 500 mm (19.7 in) in diameter, 350 mm (13.8 in) in height and 200 kg (440.9 lb). Travels are 450 mm (17.7 in) in X, 650 mm (25.6 in) in Y and 460 mm (18.1 in) in Z. With the universal automation table top fitted, 45 mm of additional installation height in the Z direction has to be taken into account.
03
DMG MORI lists 2g acceleration and up to 80 m/min rapid traverse, from direct drives in all axes. The rotary axes use water-cooled torque motors. In high-speed finishing with short moves and constant changes of direction, acceleration decides how close the machine gets to the programmed feed, more than the rapid figure does.
04
The tool magazine has 30 places as standard. Magazines with 60 or 120 places are listed as options. For mould work with long finishing sequences and duplicate tools, the larger magazines are worth pricing with the machine, since the listed data does not say whether they can be added later.
05
DMG MORI states stability and long-term accuracy for Ra < 0.2, without printing the unit. It attributes this to the thermo-symmetrical portal design, the single piece hybrid mineral cast bed with 4-point support and the water-cooled torque motors in the rotary axes. The surface actually achieved depends on the tool, the material and the toolpath.
06
The DMU 40 eVo is listed with 400 × 400 × 375 mm (15.7 × 15.7 × 14.8 in) of travel. The HSC 55 linear has 450 × 650 × 460 mm (17.7 × 25.6 × 18.1 in), so it is larger in every axis and much longer in Y.
