DMG controls cost and maximises reliability of its CTX beta 1250 4A twin-spindle turning centre

DMG says that 70% of the parts used in the construction of the CTX beta 4A machines are common to pre-existing CTX models. Proven components from DMG's Twin lathe range are also used to maintain high reliability and control cost. The CTX beta 1250 4A turn-mill centre can machine components from bar up to 102 mm diameter and 1,200 mm in length in both the main and counter spindles, as well as chucked workpieces up to 300 mm long. Both spindles have an integrated spindle motor that delivers a torque of up to 360 Nm at up to 5,000 rpm, while rapid traverses of 45 m/min allow short machining times. Two fast-indexing VDI 40-DirectDrive turrets with 12 stations (optionally 16 stations) each deploy live tools rated at 14.2 kW (40% duty cycle), supplying a torque of up to 34 Nm at up to 10,000 rpm. In addition, both turrets have a Y-axis (top ±60 mm, bottom ±40 mm) as well as a DMG Trifix precision interface at all tool stations to reduce set-up times and increase tool precision and stability. ShopTurn 3G control maximises performance from design through to finished workpiece, says DMG. One of the innovative features of this Siemens CNC system is the possibility of multi-channel programming, for which the user can choose either DIN programming or WOP (workaround-oriented programming). Graphical 3D shopfloor programming directly on the machine, together with process simulation and convenient cycles, is possible via the ShopTurn 3G user interface, as well as time-optimised programming of complex milling contours and integration of customer cycles, externally generated program modules or additional technologies via DIN code. ShopTurn 3G also makes it possible to combine ShopTurn cycles with DIN functionality.
