With a footprint of only 11.7 m², the CTX 750|1250 offers ample space for workpieces measuring ø 700 x 1,290 mm. The interplay of the left and right spindles, the optional Y-axis with +/- 85 mm travel, and the driven tools with up to 6,000 min-1 ensures productive 6-sided complete machining of complex geometries with maximum precision through integrated processes. The highly rigid machine concept of the CTX 750|1250, with linear guides up to 55 mm wide, comprehensive cooling measures, and direct measuring systems from Magnescale, guarantees positioning accuracies of 6 µm and 12”.
Powerful spindles and turrets for demanding applications
The powerful machining capabilities are primarily due to the spindles of the CTX 750|1250. The left ISM 127 spindle with 2,500 min-1 and up to 1,975 Nm torque is complemented by an ISM 80 spindle, which reaches 4,000 min-1 and 360 Nm. The spindle bore is ø 127 mm, suitable for bars ø 125 mm. Optionally, a right-side ISM 102 spindle for heavy 6-sided machining with a torque of up to 770 Nm is available. The standard VDI-50 turret with twelve tool stations enables the milling operations required for 6-sided complete machining. The driven tools achieve 4,000 min-1 and 48 Nm here. For speeds up to 6,000 min-1, a high-speed turret with 66 Nm and a direct-driven turret with 86 Nm are available as alternatives.
Energy-efficient and resource-saving universal turning
A future-oriented manufacturing process requires the use of both economical and sustainable solutions, with which DMG MORI is advancing the Green Transformation (GX). In the case of the CTX 750|1250, for example, low-friction guides and a low-consumption lubrication system are used, the machine features inverter technology for the hydraulic unit as well as frequency-controlled coolant pumps. The universal lathe also operates with advanced synchronous motor technology, motor brakes with energy recovery, and IE3 class 3-phase motors. It has energy-efficient cooling for the control cabinet and linear scales without pressure application and is standardly equipped with the DMG MORI Auto-Shutdown function. These features are part of the GREENMODE, which reduces energy consumption by up to ten percent.
Comfortable control options and autonomous operation
Integrated processes and energy-efficient machine utilization are part of the overall concept of the CTX 750|1250, as are modern control options and automated manufacturing. The machine can be equipped with CELOS X on a SINUMERIK ONE or with an alternative MAPPS Fanuc. Both variants allow for intuitive programming and quick setup of the machine. DMG MORI technology cycles, such as gearSKIVING and gearHOBBING, facilitate the programming of complex processes and expand the manufacturing technological capabilities of the CTX 750|1250.
Additional productivity is gained through autonomous operation in three shifts. Users have a variety of automation solutions available – from bar loaders to the Robo2Go Max and the MATRIS system, which can realize complex manufacturing cells.
