Overview

The DMG MORI DMC 55 H twin is a twin-spindle horizontal machining center that cuts two parts at the same time within travels of 580 mm (22.8 in) in X, 750 mm (29.5 in) in Y and 500 mm (19.7 in) in Z. DMG MORI lists workpieces up to 750 mm (29.5 in) long, 580 mm (22.8 in) wide and 500 mm (19.7 in) high, or 630 mm (24.8 in) in diameter, with a maximum weight of 400 kg (881.8 lb).

The point of two spindles is double output from one footprint, and the usual objection is that two tools are never exactly the same length or diameter. DMG MORI answers it with independent X/Y/Z axes that compensate tool dimensions, and with permanent synchronization of the spindles to each other. Each spindle is served by a scalable wheel magazine with up to 214 tools, and the chip-to-chip time is quoted at up to 2.9 s.

The dynamics are stated as accelerations of 7 / 10 / 8 m/s² with low moving masses. Positioning accuracy is 5 µm. The base structure is GGG60, credited with good damping, and all heat-generating components are cooled; compensation for changing ambient conditions is listed too.

Beyond milling, DMG MORI lists technology integration through milling, turning and grinding, and several automation possibilities. What the published data leaves out is the spindle itself: no speed, power or torque figure is given, and the 400 kg limit is not broken down per spindle position. Both belong on the list of questions for a quotation. The DMU 55 h twin shares the 580 × 750 × 500 mm travels.

Strengths & Limitations

Strengths

Two spindles for double output, with independent X/Y/Z axes that compensate differences in tool dimensions
Scalable wheel magazine with up to 214 tools per spindle
Chip-to-chip tool change quoted at up to 2.9 s
Axis accelerations of 7 / 10 / 8 m/s² with low moving masses
Positioning accuracy of 5 µm, with cooling of all heat-generating components
Milling, turning and grinding are listed as integrated technologies

Limitations

Maximum workpiece weight is 400 kg (881.8 lb)
No spindle speed, power or torque is published in the data for this model
214 tools per spindle is the upper end of a scalable magazine; the size of the base magazine is not stated
Twin-spindle work needs every tool and fixture in duplicate, so each job calls for two sets of tooling and workholding

Best For

Series production of identical parts, two at a time Workpieces up to 750 x 580 x 500 mm (29.5 x 22.8 x 19.7 in) and 400 kg (881.8 lb) Tool-intensive jobs using up to 214 tools per spindle Short-cycle parts where a chip-to-chip time of up to 2.9 s counts

Frequently Asked Questions

01 How do the two spindles of the DMC 55 H twin stay matched?

DMG MORI lists two measures. The X/Y/Z axes are independent, which allows the dimensions of each tool to be compensated, and the spindles are permanently synchronized to each other, a function it calls Syncmot. Together they deal with the differences between the two tools of a pair, which is what keeps the two parts alike.

02 What size workpiece does the DMC 55 H twin take?

Up to 750 mm (29.5 in) long, 580 mm (22.8 in) wide and 500 mm (19.7 in) high, or 630 mm (24.8 in) in diameter, with a maximum workpiece weight of 400 kg (881.8 lb). The travels are 580 mm (22.8 in) in X, 750 mm (29.5 in) in Y and 500 mm (19.7 in) in Z. The data does not say whether the weight applies to each spindle position or to both together.

03 How many tools does the DMC 55 H twin hold?

Each spindle has its own wheel magazine, which is scalable to up to 214 tools per spindle. DMG MORI does not state the size of the smallest magazine in the published data. The chip-to-chip time is given as up to 2.9 s.

04 How does the DMC 55 H twin compare with the DMC 65 h FD monoBLOCK?

The DMC 65 h FD monoBLOCK has longer travels of 650 mm (25.6 in), 950 mm (37.4 in) and 700 mm (27.6 in) in X, Y and Z, against 580 mm (22.8 in), 750 mm (29.5 in) and 500 mm (19.7 in) on the DMC 55 H twin. The twin is built for two parts per cycle within the smaller envelope.

05 What accuracy and dynamics does DMG MORI state for the DMC 55 H twin?

Positioning accuracy of 5 µm and accelerations of 7 / 10 / 8 m/s². The base structure is made of GGG60, all heat-generating components are cooled and compensation for changing ambient conditions is listed. Rapid traverse rates are not part of the published data.
