A powerful universal turning machine has been introduced by DMG MORI as the CTX 2500|700, for machining components up to 366mm in diameter from billet or 76mm from bar and to a maximum length of 705mm. Class-leading performance is claimed by the manufacturer, Gildemeister Drehmaschinen, whose managing director Harry Junger commented: “For the first time we can turn grooves up to 12mm wide in CK45 steel and drill holes to 80mm diameter.”
The ergonomic machine combines the performance and stability of two successful models in the DMG MORI range. It has the rigid machine bed and stable box guideway configuration of the NLX 2500|700, of which more than 10,000 have been sold, coupled with the VDI turret and Siemens 840D solutionline with ERGOline 21.5” touch-screen control from the CTX beta 800. DMG MORI’s proprietary app-based control and operation interface, CELOS, is included.
Top accuracy and surface quality of machined components derive from the thermostability of the lathe, which has a spiral oil jacket around the spindle to control the temperature and coolant recirculation through the cast bed. A linear scale with a standard resolution of 0.01µm is fitted in the X-axis for high precision positional feedback. Rapid traverse of 30m/min in the linear axes ensures short idle times and a Y-axis may be specified for turn-milling work of high complexity.
The turnMASTER 4,000rpm main spindle with 26kW of power and 525Nm torque or optionally the 3,500rpm / 30kW / 1,194Nm version is opposed by an 11kW / 7,000rpm / 70Nm (or 32kW / 5,000rpm / 360Nm) counter spindle.
A 6,000rpm / 32Nm cooled disc turret with VDI 40 interface is standard, while an 85Nm torqueDRIVE and a 12,000rpm speedDRIVE are available. All turrets offer space for either 12 tools, or 16 tools in the optional VDI 30 design (not for torqueDRIVE), while the BTM interface is a further option.
DMG MORI provides various automation solutions for the 2500|700. In addition to the integrated bar magazine connection, there are the options of automated chuck component load/unload via its Robo2Go mobile robotic cell or GC gantry-type loaders.
