A new machining centre has been introduced by DMG Mori that, despite having travels of 700mm, 420mm and 380mm in the X, Y and Z axes respectively, has a footprint of just 4.2m².

The DMP 70 takes up 10% less space on a factory floor than the machine it replaces, the successful MILLTAP 700, of which more than 3,000 have been sold.

Available either as a 3-axis CNC machine or fitted with an optional swivelling rotary table to enable 5-axis simultaneous machining, the production centre is ideal for the manufacture of medical parts. However, it is equally well suited to producing smaller parts in the aerospace and other demanding sectors, as well as in the job shop.

Provided that components fall within its working envelope, the DMP 70 is able to lessen the load on larger capacity, more expensive machines on a shop floor. A high degree of rigidity in the machine construction, including a grey cast iron machine bed and 35 mm wide linear guideways, allows a metal removal rate that is 10 percent higher than the maximum possible on the MILLTAP 700.

With rapid traverses of 60m/min and acceleration up to 2g, the DMP 70 offers highly dynamic performance. In its standard version, the machine is equipped with an inline, 10,000rpm / 78Nm spindle. Fast tool change and chip-to-chip times of 1.5 seconds also contribute to high productivity. The tool magazine has capacity for 15 cutters up to 250mm long, 25 tool pockets being an option.

Temperature stability and long-term accuracy have been improved through thermo-symmetrical design and optimised cooling measures. Linear scales provide high positioning accuracy, ensuring the machine meets the demands of its target sectors. Accuracy of machined components is said to be 60 percent higher than is possible on the superseded MILLTAP 700.

Scratch-proof, long-life surfaces protect against damage and boost the value retention of the machine, while steep covers promote chip evacuation. The SLIMline multi-touch 3D control with Operate 4.8 on a Siemens platform has a 19” display for ease of use and comprehensive cycle simulation ability.

An extensive portfolio of options includes high-speed spindles, various tables, coolant systems and chip conveyors. The manufacturer’s established WH 3 workpiece handling system can be connected flexibly at the left, right or front of the machine to provide a compact, automated cell requiring only 8.8m² of space.
