Future-proof 6-sided complete machining
The Machining Transformation (MX), with which DMG MORI is shaping the future of machine tool manufacturing, has a direct influence on product development. This is demonstrated by the sixth generation of CTX universal turning machines. As the latest addition to the series, the CTX 750|1250 sets new standards in terms of performance, precision and energy efficiency. On an area of just 11,7 m², it offers sufficient space for ø 700 x 1,290 mm workpieces. The combination of left and right spindles, the optional Y-axis with +/- 85 mm travel and the driven tools with up to 6,000 rpm ensures productive 6-sided complete machining of demanding geometries with maximum precision using integrated processes. This is because the highly rigid machine concept of the CTX 750|1250, up to 55 mm wide linear guides, integrated cooling measures and direct measuring systems from Magnescale guarantee positioning accuracies of 6 µm and 12”.
Powerful spindles and turrets for demanding applications
The spindles of the CTX 750|1250 play a major role in high-performance machining. The left-hand ISM 127 spindle with 2,500 rpm and up to 1,975 Nm torque is contrasted by an ISM 80 spindle. It achieves 4,000 rpm and 360 Nm. The spindle bore is Ø 127 mm, for bar Ø 125 mm. An ISM 102 spindle for 6-side heavy-duty machining with a torque of up to 770 Nm is optionally available on the right-hand side. The VDI-50 turret with twelve tool positions, used as standard, enables the milling operations required for 6-sided complete machining. The driven tools reach 4,000 rpm and 48 Nm. Alternatively, a high-speed turret with 66 Nm and a direct-drive turret with 86 Nm are available for speeds up to 6,000 rpm.
Energy-efficient and resource-saving universal turning
Sustainable production requires the use of both economical and sustainable solutions, with which DMG MORI is driving forward 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 has inverter technology for the hydraulic unit and frequency-controlled coolant pumps. The universal lathe also works with advanced synchronous motor technology, motor brakes with energy recovery and 3-phase motors of class IE3. It has energy-efficient cooling of the control cabinet and linear scales without pressurization and is equipped with the DMG MORI auto-shutdown function as standard. 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 just as much a part of the overall concept of the CTX 750|1250 as modern control options and automated production. The machine is optionally equipped with CELOS X on a SINUMERIK ONE or with an alternative MAPPS Fanuc. Both variants allow intuitive programming and fast machine set-up. DMG MORI Technology Cycles, such as gearSKIVING and gearHOBBING, facilitate the programming of demanding processes and expand the production technology possibilities of the CTX 750|1250. Production gains additional productivity through autonomous operation in three shifts. A wide range of automation solutions are available to users – from bar feeders and Robo2Go Max to the MATRIS system, which can be used to create complex production cells.
