DMG MORI NTX 2000/1500 SZM CNC turn-mill center

DMG MORI NTX 2000/1500 SZM CNC turn-mill center was built in 2018 in Japan by DMG MORI CO., LTD. The machine on offer is an excellent choice for the mass production of precision parts, which are used in such industries as automotive or aerospace. This is because the NTX 2000/1500 SZM enables simultaneous turning and milling of workpieces with even the most complex geometries, in a single working cycle. The combination of these two processes significantly reduces production costs, as well as overall working time.

The machining process is performed by using the state-of-the-art technology available on the market. It includes, among others, two spindles with a labyrinth cooling system. This system was designed for frequent use of high-pressure coolant. It ensures a constant zero-point height throughout the working cycle, regardless of the amount of generated heat. To limit the effect of thermal expansion, the temperature rise is dampened by an spiral oil jacket, which surrounds the spindle during machining. The spindle cone is in turn continuously purged with compressed air.

The rotary B axis uses a DDM (Direct Drive Motor). The motor directly transfers power to the rotary axis without the use of gears, eliminating backlash. This solution, compared to conventional worm gear systems, significantly improves productivity and guarantees fast feeds. In addition, to achieve a smooth tool feed, the SVC function reads software commands in advance to control the tool tip and automatically applies compensation. All this ensures better surface quality and shorter cycle times during simultaneous, 5-axis machining of workpieces with even the most complex geometry.

The NTX 2000SZM/1500 CNC machining center is also very easy to operate. It is controlled from a touchscreen control panel with a unified CELOS user interface, which enables consistent machine management, process visualisation and the creation of documentation. The operating system also offers the ability to extend functionality through its compatibility with various applications. The DMG MORI NTX 2000/1500 SZM turning and milling center weighs 16000 kg.
