DMG DMC 80 Linear offers fast, precise machining

The DMC 80 H linear is offered in many versions, including with an HSK-A100 tool taper and 430-Nm spindle.

Designed for larger workpieces, as with the smaller DMC 60 H, it offers high precision, minimal idle times and high dynamics. Linear drives, an intelligent tool magazine and the use of a modular building block system offer productive machining solutions, whatever the variant, says DMG. A versatile unit, the DMC 80 H linear is suitable for both production of classic components in job shops and the machining of motor and gearbox components for the automotive industry. The axes' travel ranges are said to be ideal for the machining of the crankcases and cylinder heads of v-engines and serial six-cylinder engines. The machine is also well-suited for applications in the hydraulic industry and security sectors. For the 5-axis version, there's a 630 by 630 mm clamping surface that can accommodate parts up to 1,000 mm in diameter, 900 mm high and a weighing up to 600 kg. The standard NC-rotary version can accommodate parts up to 1,100 mm diameter and of weight 900 kg. With the standard pallet changer, it has an overall footprint of just 19 sq m. In addition to the standard 12,000 rpm spindle (20 kW, 110 Nm), there's an 18,000 rpm motor spindle and an HSK-A100 spindle with 430 Nm that is said to set new standards in heavy duty machining. The standard HSK-A63 version boasts 40 tools, while up to 363 tool pockets are available, if additional wheels are added. Chip-to-chip time is 2.6 secs. Equipped with the large HSK-A100 tool interface, the magazine can take up 243 tools in its most extensive version. Both expansion options can accommodate tools with a length of up to 650 mm. Rapid traverse rates of up to 80 m/min guarantee fast machining speeds, and the 0.8 g acceleration delivers this speed quickly. To ensure long-term accuracy of the linear drives, motor spindle and rotary table, these elements are cooled. The linear drives are all located outside of the work area, incidentally, so they have no thermal impact during machining. Good chip disposal to a central via steep chip guide plates directs swarf to a central chip disposal system. A centrally located spiral conveyor transports the chips to the rear of the machine. Siemens 840D solutionline, offering operators extensive programming possibilities, is integrated in the clear and ergonomic SLIMline-panel with 15"screen. See related feature article here
