First corporate development of DMG & MORI SEIKI
The compact machining centre MILLTAP 700, the first joint development of DMG and MORI SEIKI, documents their high standard to offer significant added value to suit all applications. The MILLTAP 700, displayed on the IMTEX 2013 in Bangalore, achieves absolute top values in all processes and with its combination of impressive work capacity and chipping performance. It also achieves a so far unrivalled performance on the tapping centre market.
Productivity and efficiency were at the core for development of the new MILLTAP 700. For this reason, DMG and MORI SEIKI have concentrated their innovative power and equipped the compact machining centre with a series of outstanding technical details. The usual high machining speed is supported by a high-speed tool changer which achieves tool change times of 0.9 seconds and chip-to-chip times of less than 1.5 seconds, enabling a highly efficient process. Its key features include the dynamic response of up to 1.6 g in the linear axes as well as fast axis movements up to 60 m/min which significantly increases productivity. Furthermore, the MILLTAP 700 considers aspects like process reliability and maintenance costs. Its triangular-bed design as well as the static cover of the X-axis optimise the chip flow and enable parallel disposal of the chips. Users can either position the cooling system on the machine from the front or back. All in all the innovative machine concept impresses with a width that is 30 per cent less compared to the competition, which is due to the optimised table design. The footprint of the MILLTAP 700 is 10 per cent less compared with the competition.
Despite all these compactness, the work area with 700 mm in the X-axis and 420 mm in the Y-axis (with a Z-path of 380 mm) is generously dimensioned and above all designed ergonomically in such a way that perfect accessibility is ensured. The sturdy machining table and the wide distances between the linear guide ways enable the machining of work pieces up to 400 kg. A number of clamping options also promises highest flexibility.
On the spindle side, the MILLTAP 700 impresses with a high torque 10,000 rpm spindle, whereby the machinable material spectrum can even be increased with the optional high-speed spindle with 24,000 rpm. With a spindle drive of 25 kW the new development of DMG and MORI SEIKI is complete top of the range. Furthermore, the symmetric spindle head ensures extreme rigidity and high-thermal stability. The rigidity of the machine is also helped by the C-frame design and usage of robust castings. The user benefits with highest surface quality of the work piece and long tool life.
Apart from the manufacturing and process-relevant features, the MILLTAP 700 presents an outstanding control performance. The adapted Siemens 840D solutionline operate with Sinamics 120 compact inverter and 10 inches monitor ensures simple and efficient programming. The system guarantees highly dynamic contour accuracy and efficient program sequences. Optionally, the MILLTAP 700 can also be equipped with the PROGRESS line, which clearly displays the remaining time and quantity of a complete machining order as status control.
The topic of energy efficiency is dealt with by DMG and MORI SEIKI with a perfected energy management. Here, the CNC control, combined with efficient drive technology, ensures an energy consumption that is up to 30 per cent reduced in direct comparison with competitor machines.
