Dmg Mori Pfronten Open House

February 4, 2019 by DMG Mori - press release International trade visitors at DMG Mori’s annual open house, Jan. 22-26 Machine tool manufacturer DMG Mori  (Bielefeld, Germany) presented its entire technological expertise at its traditional open house exhibition at Deckel MahoPfronten, Germany, Jan. In Pfronten DMG MORI will demonstrate its competence in automation with an example of a flexible automated production system comprising the two horizontal machining centres NHX 5000 and DMC 60 H linear plus an LPP 24 linear pallet pool system. Another highlight at the Open House with regard to automation is a flexible automated production system. Highly dynamic, long-term stable 5-axis machine concept – compact on 3.5 m² DMG MORI relies on the long-term stable gantry design for the ULTRASONIC 20 linear 2 nd generation in order to meet the demands on precision for ultrasonic machining. Whereby the machine tool manufacturer was able to reduce the footprint to a compact 3.5 m². While DMG MORI once again underlined its high level of innovation at the company's traditional Open House event at Deckel Maho in Pfronten, Germany last month, there were only three world premieres on show among the 80 machines showcasing the company's wide range of product offerings. Clearly a sign of the company's consolidation efforts, including a reduced number of machines introduced to the market each year, as well as the reduction of product offerings from 300 to 150.

For several decades, DMG MORI has been setting standards in the market of complex universal turning with its CTX series. A particularly far-reaching milestone here was the integration of a B-axis some years ago for the first time, thus extended the range of services of the at the time completely newly developed series to the turning/milling range. Today, the CTX range includes nine different sizes, based on which a total of 40 expansion options for workpieces of different sizes can be configured task-optimized. The CTX beta 1250 TC in its second generation now represents the most recent highlight of the innovative platform strategy of DMG MORI, which will celebrate its world premiere at the open house event in Pfronten.
With the CTX beta 1250 TC 2nd generation, DMG MORI expands its portfolio of Turn & Mill Centres once again within the CTX range. The CTX beta 1250 TC is designed for universal application in turn/mill machining of workpieces up to ø 500 mm and 1,210 mm turning length, whereby the Y-axis stroke, which has been increased by 50 mm to 250 mm, increases flexibility during off-centre machining. The feed rate which is increased by up to 65 % to max. 50 m/min ensures high productivity already as standard. The robust direct linear measuring systems from MAGNESCALE ensure highest precision in all three linear axes. Furthermore, the optional linear drive generates even more speed, dynamics and precision. The direct drive accelerates the Z-axis with 1g to up to 60 m/min with highest long-term precision, including a 5-year warranty on the direct drive.
Another core element of the new CTX beta 1250 TC is the fast B-axis in Direct Drive technology with a continuous swivel range of ±120°. However, the distinctive feature is the new turn/mill spindle compactMASTER. With a length of only 350 mm it generates a space gain of 170 mm, which has enabled machining of workpieces of up to 350 mm length with tools of up to 400 mm length. In the process itself, the new compactMASTER spindle with HSK-A63 interface (optional Capto C6) provides an rpm of 12,000 rpm, a torque of 120 Nm as well as a performance of 22 kW. A 20,000 rpm high-speed version is also available as an option. Meanwhile, the generously dimensioned 70 mm diameter spindle bearing of the compactMASTER ensures stability and precision in interaction with the temperature-stabilising sleeve cooling.
The CTX beta 1250 is equipped with a disk magazine with 24 pockets as standard. Optionally, a 48- and an 80-pocket chain magazine are available. The machine’s range of applications can thus be considerably increased, particularly for a range of components that are frequently changing - either due to the reduction in tooling times or due to the option of targeted usage of sister tools.
To take account of the increasing energy prices, the new CTX beta 1250 TC of the second generation is equipped with a large number of energy-saving features. A cooling unit with added water, an energy-efficient control cabinet cooling unit, synchronous motors for higher acceleration rates and reduced energy consumption, as well as hydraulic inverter units reduce energy consumption by more than 25 %.
The CTX beta 1250 TC is equipped with the latest 3D control technology. The standard version comes with CELOS by DMG MORI with 21.5” ERGOline control and SIEMENS. CELOS provides a uniform user interface for all new high-tech machines from DMG MORI. A unique 21.5” multi-touch screen displays all CELOS APPs, which provide the user with integrated management, documentation and visualisation of order, process and machine data. Additionally, machine operation is simplified, standardised and automated. Optionally, the machine can be equipped with Operate 4.5 on SIEMENS 840D solutionline including 19“ ERGOline.
In both cases, the standard version of CTX beta 1250 TC already impresses with ShopTurn 3G for workshop-oriented programming. Complete flexibility between DIN and workshop-oriented programming is guaranteed by the DIN / ISO interface. A combination of ShopTurn cycles with DIN functions is also possible. Possible applications of the CTX beta 1250 TC are rounded off by exclusive technology cycles that are available as an option.
Based on a simple and dialog-supported input of the required parameters, the machining functions for off-centre turning and milling, for example, can be generated as well as special threads with the multi-thread cycle, and all this without a CAD/CAM system. Furthermore, a tool sorting cycle is available, which reduces idle times by sorting the tools in the chain magazine according to their call parameters. In total, based on the innovative technology cycles, up to 60 % of programming time can be saved.
“The success of our Turn & Mill machines is also the result of fast and simple programming. In addition to the standard options provided by the Shop Turn 3G controller, our exclusive technology cycles mentioned above also accelerate the process. This makes the CTX TC series a profitable alternative for a growing number of users compared to sequential machining on different machines,” believes Harry Junger as Managing Director of GILDEMEISTER Drehmaschinen GmbH.

Dmg Mori Pfronten Open House 2019

On the occasion of the open house event at DECKEL MAHO Pfronten, DMG MORI expands the series of the duoBLOCK of the 4th generation with two fascinating world premieres. This includes the universal milling machine DMU 100 P duoBLOCK with its outstanding milling performance, which impresses with its powerful heavy-duty chip removal as well as regarding the precise all-round functionality. Furthermore, the DMC 125 FD duoBLOCK as second world premiere introduces its users to the flexible as well as productive possibilities of turn-mill machining with automatic pallet changing.
The 5-axis machines with highly stable duoBLOCK design with 30 % more precision, performance and efficiency enable highest machining performance and maximum component accuracy with high dynamics. From extremely hard materials like in the aerospace industry to the highest of surface quality demands, for example in tool and mould making, the duoBLOCK machines of the 4th generation thus provide the best prerequisites in any case.
The overall rigidity of the duoBLOCK design which is increased by 30 % was achieved by way of FEM analysis of the structure and strengthened components. This includes amongst others the size 50 ball-thread drives in all axes, size 55 linear guides in the Y-axis, larger YRT bearings in the B- and C-axis as well as the optimized 3-point support for shortest commissioning times and best chip removal conditions.
The accuracy values, which are improved by 30 % compared to the previous version, are achieved on the one hand through the high stability and on the other an intelligent temperature management. Extensive cooling measures are now part of the standard equipment for the motors in the B and C-axes, the motor spindle and the headstock housing as well as for linear guideways, ball-thread drives and bearings in the X, Y and Z-axes and last but not least for the servo motors in the Y and Z-axes. A precision package is optionally available with cooling of the X-axis motor, the gear in C- and A-axis, the ball-thread drive nuts in X / Y / Z as well as a bed cooling. In addition, a thermal shield reduces negative temperature effects from the machine’s environment.
Another benefit of the duoBLOCK principle are the extensive building blocks for customized complete solutions in a wide range of applications. The choice of spindles, for example, includes ideal versions for all areas, from high-speed through to heavy duty machining – including the motor spindle powerMASTER 1000 with 1,000 Nm torque at 9,000 rpm or the drive spindle available from quarter 4/2015 up to 1,300 Nm at 8,000 rpm.
Another novelty is the modular wheel magazine with up to 453 tool positions, which can be loaded in parallel to main production and idle times and requires little space due to a footprint reduced by 41%. Short provisioning times of max. 5.6 seconds and changeover times of 0.5 seconds also increase productivity of the duoBLOCK machines.
In future, the most recent new developments will benefit from the cited basic properties of the reviewed duoBLOCK now in its 4th generation. As classical universal machine, the DMU 100 duoBLOCK provides its users with traverse paths in the X-, Y- and Z-axis of 1,000 x 1,250 x 1,000 mm, with a size of the NC round table of ø 1,100 x 900 mm. The maximum workpiece weight is 2,200 kg.
In addition, the DMC 125 FD duoBLOCK provides its customers with a unique turn-mill performance for workpieces up to 2,000 kg with a work area of 1,250 x 1,250 x 1,000 mm. Furthermore, the automatic disk changer increases productivity due to the option of tooling parallel to production time.
