EMCO Extends Series of Traveling Column Machining Centers

EMCO has extended its MMV series with the MMV 4200, 5200 and 6200 models, which feature enlarged travel paths (X= 4200, 5200 and 6200). The three-, four- and five-axes machines can be used for complete machining of very large and heavy parts in one clamping. The new models feature a high-performance motor spindle with 0-15,000 rpm speed range, 46 kW spindle power and up to 170 Nm torque. 40 tool pockets available as standard, optionally expandable up to 120 pockets.

The compact machine bed of the traveling column machining centers is a heat-treated, welded steel structure that provides a torsion-resistant and stable base for all components and machining operations. The production of large and heavy workpieces up to 8,000 kg is enabled by a powerful motor spindle with 46 kW spindle power, a torque of up to 170 Nm and a spindle speed of up to 15,000 rpm (18,000 rpm HSK-A63). Both spindle versions are grease-lubricated. The new versions of the previous model are said to support complete machining of very long and heavy workpieces without reclamping. A new modular system ensures a variable choice of workpiece sizes up to 6200 mm during machining. With this system, rapid traverses of up to 60 m/min can be achieved.

The machine versions with swivel head (b-axis) and rotary table (c-axis) are reportedly suited for five-axis simultaneous machining. Both the swivel head and the rotary table are driven by dynamic torque motors. The swivel head available in the standard versions has a range of up to ± 120° and a speed of 50 rpm; the rotary table n x 360° has a speed of up to 100 rpm. The rotary table with Ø 900 mm is designed for workpiece weights up to 2000 kg. All linear axes are already equipped with glass scales as standard. According to EMCO, the dynamic linear axes and the torque drives of the rotary axis create ideal conditions for five-axis simultaneous machining of complex workpieces.
