Class-leading performance is claimed by the manufacturer, Gildemeister Drehmaschinen, whose managing director Harry Junger Says: “For the first time, we can turn grooves up to 12 mm wide in CK45 steel and drill holes to 80 mm diameter.”
The machine 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-in 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, plus coolant recirculation through the cast bed. A linear scale with a standard resolution of 0.01 micron is fitted in the X-axis for high precision positional feedback. Rapid traverse of 30 m/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 4,000 rpm main spindle with 26 kW of power and 525 Nm torque or optionally the 3,500 rpm / 30 kW / 1,194 Nm version is opposed by an 11 kW / 7,000 rpm / 70 Nm (or 32 kW / 5,000 rpm / 360 Nm) counter-spindle.
A cooled disc turret with VDI 40 interface is standard, featuring 6,000 rpm/32 Nm driven tools or 85 Nm torqueDRIVE or a 12,000 rpm speedDRIVE. All turrets offer space for either 12 VDI 40 tools or 16 VDI 30 design (not for torqueDRIVE), while the BTM interface is a further option.
DMG Mori offers 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.
