DMG MORI will be confirming its status as a world market leader in the field of metal-cutting machine tools with 7 world premieres as well as a representative cross-section of its high-tech portfolio at the EMO in Milan
In this arcticle we would like to introduce the four world premiers from the turning range of DMG MORI. Among the presented machine tools at EMO Milan will be the production turning machine SPRINT 32|5 with the extension stage to SPRINT 32|8, the second generation of the turning&milling machines CTX gamma TC in two different sizes, and the NLX 6000|2000 turning/milling centre for large workpieces.
SPRINT 32|5 and SPRINT 32|8 –Extension of the successful SPRINT series for parts with diametres of up to 32 mm
The SPRINT 32|5 is designed for both short and long turning of workpieces of up to ř 32 x 600 mm. With a base area of less than 2.8 m˛, the new development is an extremely compact production facility. The SPRINT 32|5 machines materials in rod form up to 32 mm in diameter using two spindles and a 2-channel controller. DMG MORI keeps part costs to a minimum in this way. 22 tools on two independent workpiece carriers also make it possible to carry out complex machining processes. The automatic lathe also machines demanding workpieces radially at the main spindle with four driven tools. In total the machine is equipped with five linear axes and on C-axis for the main spindle. Other options are the unloading device for workpieces up to 600 mm in length, and the high-pressure coolant supply with 120 bar.
As an upgrade, DMG MORI is presenting the SPRINT 32|8 at EMO as another extension of the SPRINT range. The SPRINT 32|8 is equipped with 3 independent linear carriers for 4-axis machining on the main spindle and offers space for up to 28 tools. The machine has six linear axes in total including a second Y-axis. Two C-axes are available as well – one for the main spindle, one for the counter spindle. In addition to the attainable pluses in performance and flexibility in relation to complex components the ergonomic operation and the durable construction underline the performance of this innovation.
CTX gamma TC 2nd Generation –Complete machining with the new compactMASTER® turning/milling spindle
Better performance and a bigger working area are the main features of the new CTX gamma 1250 TC and CTX gamma 2000 TC. The indisputable highlight of the two 2nd generation machines from DMG MORI is the ultra-compact turning/milling spindle. Their compact dimensions translate into a space saving of 70 mm, meaning that 550 mm long workpieces can be horizontally drilled out or hollow turned. The elevation in the X-axis has been increased by 150 mm, thus extending the options for the machining of large workpiece diameters. In addition, the Y-axis now offers 20 mm more travel. The maximum turning length is 1,300 mm in the case of the CTX gamma 1250 TC. The big sister model has a turning length of 2,050 mm. The turning diameter is 700 mm, respectively.
In its development of the compactMASTER® turn & mill spindle, DMG MORI has increased the turning torque by 130 percent, meaning that up to 230 Nm is available to users. The spindle operates at speeds of up to 12,000 rpm. The new CTX gamma TC models also have improved dynamics: The feed speeds of 50 m/min in the X, Y and Z directions have been increased by up to 65 percent.
With the optional linear drive in the Z-axis, the turning/milling machines achieve up to 60 m/min in fast feed and an acceleration of 1g. Equipped with a B-axis and the technology cycle, the two world premieres are ideal for 5-axis simultaneous machining. For 4-axis production turning, a bottom revolver is optionally available as the 2nd tool carrier. This can accommodate up to 12 power tools at up to 10,000 rpm.
NLX 6000|2000 –powerful turn & mill machining with torque of up to 12,000 Nm, long parts and large diametres
With more than 2,300 installed machines the SL series from DMG MORI has written an impressive success story over the last years.
The NLX 6000|2000 now opens a new chapter setting new standards in the powerful turn & mill machining of workpieces up to 2,000 mm in length with a diameter of 920 mm – with a chuck diameter of 600 mm.
The basis for productive and high-precision machining on the NLX 6000|2000 are the tremendous rigidity of the drive trains, the structure of the machine bed and the flat guides with their high damping characteristics.
The outstanding milling performance is guaranteed by the revolver magazine with BMT® technology.
The integrated direct drive motor achieves up to 4,000 rpm and a high torque of up to 117 Nm. The highlight of the NLX 6000|2000 is the application-oriented selection of powerful spindles. The range starts at type B with a spindle diameter of 185 mm. In this case the maximum speed is 1600 rpm, and the torque is up to 7,000 Nm. The range of spindles is rounded off by two spindles, each with impressive torques of up to 12,000 Nm. Type C has a diameter of 285 mm, and for the type D it is an impressive 375 mm.
