With the CTX 750|2000, DMG MORI is presenting a universal lathe at the Open House Bielefeld that will continue the success of the CTX universal lathes. With its large working area, the world premiere is designed in particular for the production of large components and long shafts. Thanks to left and right spindles and a 170 mm Y-axis for off-center milling with driven tools, 6-sided complete machining of demanding workpieces is possible. Like its smaller sister machines, the CTX 750|2000 therefore stands for maximum flexibility in an attractive price segment. The new size in the CTX series also serves the four pillars of Machining Transformation (MX), with which DMG MORI is shaping the future of manufacturing: Process Integration, Automation, Digital Transformation (DX) and Green Transformation (GX).
"In the premium segment of universal turning, we see the CTX 750|2000 as the perfect companion for the complete machining of long workpieces," says Dr. Claudio Merlo, Managing Director of DMG MORI Tortona, positioning the new development. The work area is dimensioned for workpieces with a diameter of 700 mm and a length of 2,040 mm. It is also easy to automate, for example with the Robo2Go Max. The app-based CELOS X control system with 24" multi-touch display enables simple integration into company networks and drives digitization forward - naturally with the highest safety standards. Modern drives such as the synchronous spindle motors and GREENMODE ensure energy-efficient operation. This reduces energy consumption by up to ten percent.
Stability and extensive cooling measures for performance and accuracy
The CTX 750|2000 has a left-hand spindle with a speed of up to 3,250 rpm and a maximum torque of 1,975 Nm. The right-hand spindle reaches 4,000 rpm and 770 Nm. The turnMASTER spindle concept with four bearings ensures maximum stability and precision, as well as offering a large bar capacity of up to ø 127 mm. The positioning accuracy in the C-axis is 0.001°, while the X- and Y-axes are equipped with a direct measuring system from MAGNESCALE as standard. The air/oil cooling for the turret gears ensures optimum temperature control. In the top performance option, a VDI 50 turret with direct drive enables high-speed milling of demanding applications. The driven tools achieve speeds of up to 6,000 rpm and a torque of 85 Nm. The Y-axis can be moved by +/- 85 mm so that workpieces can be machined off-center.
Automation solutions from a single source
Automated production solutions are an essential way for DMG MORI to maintain competitive production in the long term. With the CTX 750|2000, autonomous operation can be realized in unmanned night and weekend shifts. The Robo2Go Max is suitable for loading and unloading chuck parts or shafts in medium batch sizes. The robot with a payload capacity of 210 kg is designed for shaft parts weighing up to 115 kg with a maximum length of 1,200 mm and a diameter of 200 mm. Such a solution brings additional flexibility to production automation.
