Vertical turning centers
The VTC 5000 series by MAG are large-table vertical turning centers (VTCs) that includes 6-meter, 7-meter and 8-meter models. The 7- and 8-meter table models have a load capacity of 250,000 kg (550,000 lbs). All models in the large-table VTC series have S1 (continuous duty) table power of 200 kW (267 hp). The new large VTCs have a modular design, allowing various combinations of modules to create a machine tailored to specific customer applications. The 5-meter hydrostatic table is engineered to support extreme loads up to 150,000 kg (330,000 lbs), while turning parts at up to 75 rpm.
The VTC 5000 shown in the photo is an adjustable rail model offering a cross rail that is both an infinitely variable positioning and a machining axis. The X/Z traverse rate is 20 m/min (787 ipm) and the rail-elevating rate is a brisk 2000 mm/min (78 ipm). Full X-axis travel right and left of center allows machining from both sides and accommodates probing of diameters. W-axis machining provides improved part geometries, while the hydrostatic ram’s high dynamic stiffness allows heavy cuts and produces better surface finishes.
These VTCs can be equipped with an optional live spindle for grinding, milling, drilling and tapping capabilities, as well as a C-axis for full contouring. Various tool tapers, including KM 80, Capto C8 and 50 taper are available. The tool magazine is ergonomically designed, allowing floor level tool changeout and eliminating the need for ladders or platforms.
