DMG B-axis turning centre boasts lower turret

DMG's CTX beta 1250 TC 4A features a powerful upper B-axis mill-turn spindle and a conventional lower turret with live tool stations and direct drive.

Full text: Compared with the single B-axis variant of this lathe, the new model with additional bottom turret is able to carry out more complex work at the main spindle. Either or both turrets can operate at the counter spindle if that option is chosen, or else simultaneous work at both spindles can be undertaken. The productivity potential has been increased by up to 50% compared to the purely B-axis version, it is claimed. Harry Junger, managing director of Gildemeister Drehmaschinen GmbH, says: "The CTX lathe is now our top model for the production of medium-sized workpieces up to 1,250 mm long by 390 mm diameter, or from bar up to 65 mm or optionally 76 mm." The B-axis, with its 12,000 rpm motor spindle, swivels by ± 100° and is supplied with HSK-A63/Capto C6 tools from a 24-position disc magazine, although an 80-position chain magazine is an option. The bottom VDI 40 direct-drive turret has a ± 40 mm Y-axis and 12 driven stations (optionally 16) capable of speeds of up to 10,000 rpm. All tool stations are equipped with the DMG TRIFIX interface, which offers reduced set-up times, as well as increased tool precision and stability. The 19" screen of the DMG ERGOline CNC enhances reading comfort, while SOFTkeys allow the integration of additional and more detailed status information. The Siemens ShopTurn 3G user interface provides G-code or conversational programming, or a combination of the two, together with process simulation and an Ethernet port for fast data exchange.
