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.
