Our best estimate for a multi-spindle automatic in this class — not a quote from DMG Mori. Configuration moves it a long way.

Overview

The DMG MORI GMC 35ISM is a CNC multi-spindle automatic with 6 spindles for bar up to 35 mm (1.38 in) and turning lengths up to 100 mm (3.94 in). DMG MORI does not show it in the current lineup, so it is most likely to be met as a used machine, and the listed figures here should be confirmed against the documentation of the machine on offer.

ISM stands for Integrated Spindle Motor: every spindle has its own motor, listed at 16 kW (21.5 hp) and 6,300 rpm per spindle. On a drum machine with one central drive all spindles turn together. With a motor in each spindle the speed can suit the operation at that station, slow for threading or a large drill and fast for finish turning, which is the main reason to look for this type.

The listed figures show up to 31 CNC axes, up to 3 cross slides per spindle, up to 2 end-working units per station and up to 42 tool positions, with a back-working spindle that has a C-axis for the cut-off side. The words up to matter on a used machine: count the slides and units fitted, because the equipment of each station decides what the machine can make. Control is Siemens 840D sl. The machine weighs 11,000 kg (24,251 lb) and occupies approximately 4.5 x 2.5 m (14.8 x 8.2 ft).

Strengths & Limitations

Strengths

6 spindles, each with an integrated spindle motor listed at 16 kW (21.5 hp) and 6,300 rpm
Up to 31 CNC axes, with up to 3 cross slides per spindle and up to 2 end-working units per station
Back-working spindle with C-axis for machining the cut-off side
Up to 42 tool positions under a Siemens 840D sl control

Limitations

Bar capacity is 35 mm (1.38 in) and turning length 100 mm (3.94 in); larger or longer parts are outside its range
Axis, slide and tool counts are all listed as up to, so the equipment fitted to a given machine may be less
At 11,000 kg (24,251 lb) on roughly 4.5 x 2.5 m (14.8 x 8.2 ft), floor loading and access need checking before a machine is moved in

Best For

Bar parts up to 35 mm (1.38 in) in diameter made in large series Short parts within 100 mm (3.94 in) of turning length Parts needing back-working with a C-axis after cut-off Operations that want a different spindle speed at each station

Frequently Asked Questions

01 What does ISM mean on the GMC 35ISM?

Integrated Spindle Motor. Each of the 6 spindles has its own motor, listed at 16 kW (21.5 hp) and 6,300 rpm per spindle, so spindle speed does not have to be one compromise value for every station.

02 What bar size and part length does the GMC 35ISM take?

The listed figures are 35 mm (1.38 in) of bar capacity and 100 mm (3.94 in) of turning length. The machine has 6 spindles and a back-working spindle with C-axis for the second side of the part.

03 How many axes and tools does the GMC 35ISM have?

Up to 31 CNC axes and up to 42 tool positions are listed, built from up to 3 cross slides per spindle and up to 2 end-working units per station. These are maximum figures; an individual machine may carry fewer slides and units.

04 What should I check on a used GMC 35ISM?

Start with the equipment: how many cross slides and end-working units are fitted at each station, against the listed maximums of 3 and 2. Then confirm the control, listed as Siemens 840D sl, and plan the installation around 11,000 kg (24,251 lb) and approximately 4.5 x 2.5 m (14.8 x 8.2 ft).
