The DMU 270 P machines large parts up to 12,000 kg.
The rigid structure of the gantry machine concept with vertically traversing crossbeam and hydraulic weight compensation has been enhanced.
DMG MORI offers gantry machines for the large part manufacturing industry. Compared with the DMU 210 P, the latest DMU 270 P gantry machining center has longer XYZ travels of 2,700 x 2,700 x 1,600 mm. They represent increases of 50% in the transverse direction and by approximately 30% in the longitudinal and vertical directions. The work area is increased by 235%. The interference contours are also improved due to the newly designed milling head. A further advantage is that the space requirement has been kept low by appropriate design of the additional components. Maximum workpiece dimensions are increased to a 2,800 mm diameter and 1,800 mm height with a permissible workpiece weight of 12,000 kg.
The rigid structure of the machine concept with vertically traversing crossbeam and hydraulic weight compensation has been further enhanced. The basic machine is made entirely of high-quality castings (GGG60). The B-axis milling head with a swivel range has been extended from 210° to 250° and is capable of swiveling to 30° in the negative direction. Together with the larger B-axis bearing, DMG MORI reported this results in a milling head housing with 20% higher rigidity, extending the range of applications. Typical applications include tool making, moldmaking, mechanical engineering, aerospace industry, energy management and medical engineering. Idle times are reduced due to the increased swivel speed of the B-axis with 30 RPM and a full swivel time of 1.5 seconds. The integral cables are designed for longer service life.
The newly developed B-axis works in conjunction with a more rigid NC rotary table that can be more accurately positioned. With a larger bearing and improved toolholding, this provides a torque of 34,000 Nm and is driven at an increased maximum speed of up to 14 RPM by means of two compact gearboxes that are electrically braked. In addition to the higher B-axis swivel speed and the enhanced NC table, the DMU 270 P offers high dynamics.
The powerMASTER 1000 motorized spindle with 9,000 RPM, a maximum of 77 kW and 1,000 Nm torque is designed for effective heavy-duty chip removal. As well as the standard SK 50 / HSK-A 100 motor spindle with 12,000 RPM, 44 kW and 288 Nm torque, five further spindles are available as an option - including a unit rated at 15,000 RPM with 52 kW at 430 Nm or the 35 kW spindle with HSK 63 interface and a maximum of 18,000 RPM for high-speed cutting. According to the company, the larger-than-average range of main drives is supplemented by the offer of the HSK 100 gear-driven spindles with 1,550 Nm at 6,300 RPM and 44 kW.
As an alternative to the B-axis arrangement, the range of gantry machine modules includes an A-axis milling head housing with swivel axis parallel to the X-axis, which accommodates the appropriate motor spindles.
In conjunction with the high machine rigidity, DMG MORI reported that a constant overall machine temperature control with the cooling of all internal heat sources on the DMU 270 P leads to a further improved positioning accuracy compared with the smaller DMU 210 P gantry machine with Pmax < 9 / 10 / 9 um. For this purpose, cooling measures have been implemented on all ballscrews, housings and motors of the main and feed drives, all linear axes and the B-axis and C-axis of the milling head and rotary table. A further effective measure is the temperature control of the frame and machine bed. In addition, insulation at the rear of the electrical cabinet shields any heat produced, which, together with improved electrical cabinet cooling, helps prevent any negative effects. The electronic compensation devices, which are specially matched to the DMU 270 P, eliminate any residual displacement that may be caused by heat or the effects of static or dynamic forces.
The Spindle Growth Sensor (SGS), included as standard with the thermo-symmetrically designed gantry machine, prevents axial spindle displacement. A temperature control feature for the whole coolant system and a Thermoshield for shielding the machine bed from airflow are also available.
"The DMG MORI modules for the DMU 270 P gantry machine enable production time to be increased and idle times to be further reduced and provide an additional range of automation equipment," said a company spokesperson. "The consequential growth in universality and productivity for 5-axis milling and the future combination with turning operations in a single set-up form the basis for a significantly extended range of applications." The wheel magazine, similar to the 4th generation duoBLOCK machines, enables rapid tool changeover. An upgrade for the standard wheel with 63 pockets to 123, 183 or 243 pockets in the version with four wheels enables the machine to be ideally matched to customer requirements. The wheel magazine is also compact for minimal space requirement. The productivity of the gantry machine is also improved by the increase in NC table speed in rapid traverse mode and the increased swiveling speed of the milling head.
Planned options include the future DMC 270 U version of the machine with pallet changer, and the DMC 270 FD fitted with a milling/turning table to form a gantry milling/turning center. Additional automation devices, such as the use of a pallet magazine or the integration of several DMC 270 U gantry milling centers with a linear pallet magazine to form flexible manufacturing systems, are already planned.
Energy savings have been implemented into the DMU 270 P. The enhanced and optimized machine temperature control necessitates the use of efficient, energy-saving cooling units. In addition, the cooling power required at any particular time is automatically adjusted to the cooling requirement of the machines. Likewise, the pumps, such as the coolant pumps, are classed as energy efficient due to speed controllers. An automatic power display, for example on the CELOS interface, not only shows the machine operator the current energy consumption but also prompts the appropriate savings.
The large work area of the DMU 270 P gantry machine with a volume of 11.7 m3 can be easily accessed from the front, the side or from above. The improved view of the work area makes for user-friendly machine ergonomics for effective set-up and in automatic mode. The work area is also fully clad in stainless steel and, if it should be necessary to change a window, this can be carried out from the outside. The DMU 270 P is offered with CELOS with 21.5" ERGOline and Siemens. CELOS APPs provide the user with integrated management, documentation and visualisation of order, process and machine data. CELOS is compatible with PPS and ERP systems, can be networked with CAD / CAM applications and is ready for future-oriented CELOS APP extensions. As standard, the machine is equipped with Operate 4.5 on Siemens 840D solutionline including 19" ERGOline.
