“Today’s machining center users focus on aspects such as machine construction, pallet magazine, traverse paths, process dependability, high productivity and precision. In these terms, the MC series scores well with a very rigid build, high mechanical accuracy and Heller’s twin-drive in the Z axis which ensures symmetric force application and free chip fall,” Trampus said.
For varying batch sizes and a variable range of parts and materials, the MC series machines are capable of high-speed cutting, heavy cutting, dry or MQL machining at full produc- tivity in series or for parallel processing. Users can specify spindle size and taper, tool magazine, and chip disposal, resulting in an attractive price/performance ratio. The MC series offers a choice of gear-driven spindles
for power, speed, high-power, or power/speed to provide feed thrusts of 15000 N in the X and Y axes, 20,000 N in the Z axis; traverse speeds of 60 m/min, and torque of up to 2300 N•m. The high-capacity 630-mm pallet changer
can handle workpieces to 900-mm diam, 1200-mm high, weighing up to 1400 kg.
The MC5000 model demonstrated on the Troy plant floor at a Heller open house includes a 630-mm pallet, HSK 100 spindles, and working cube of 800 mm (part diameter of 900 mm) for high-load capacity and metalcutting productivity across a range of materials and part designs. Another significant benefit of the series, especially in terms of automation, is tool management. The MC series is avail- able with a chain-type tool magazine with storage capacities for 54, 80, 160 or 240 tools and a rack-type magazine with more than 400 storage places enabling tool loading parallel to machining. Chip-to-chip time is 4 sec or less. Since its premiere at EMO 2007, more than 650 machines of the series have been sold and installed at leading manufac- turers worldwide. ME
