Our best estimate for the DMG Mori GMX 400 is $350,000 - $550,000. This is an estimate for a cnc grinding machines in this class, not a quote from DMG Mori; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/dmg-mori-gmx-400#price; the request is passed to DMG Mori or an authorised dealer.
No. The GMX 400 is not in DMG MORI's current lineup, and the figures listed for it are unconfirmed. Anyone assessing a used machine should work from its nameplate and original documentation. The listed control, a SIEMENS 840D with a 15 in TFT screen, is consistent with an older machine.
The listed maximum turning diameter is 25.2 in, the maximum turning length is 62.4 in and the maximum bar diameter is 3.5 in. Chuck diameter is listed as 7.9-15.7 in. The table also carries a 20 kg (44 lb) workpiece weight row that sits with its tool-grinding rows and does not fit these turning figures, so confirm the weight limit separately.
The listed figures show a B-axis that swivels ±120 degrees, an HSK63-A tool mount and a 12,000 rpm maximum spindle speed. Tools are held in a 60-station shelf magazine, with an average chip-to-chip time of 8 s. There is also one 12 Position turret with VDI 40 tooling.
The listed gross weight including the CNC is 44,000 lbs and the power requirement is 88 kW. Setup dimensions are given as 366.1/181.1/120.1 in (L/H/B). The coolant tank volume is 264.2 gal., so allow for the filled tank and for coolant handling when planning the floor space.
