Mazak VTC-5

The Mazak VTC-5 series is a vertical traveling column 5-axis machining center designed for long, flat workpieces that do not fit on trunnion-style 5-axis machines. Available in multiple configurations including the VTC-800/30SR (high-speed), VTC-800/30HD (heavy-duty), and VTC-800/30SD (rotary table variant), the machine uses a traveling column that moves over a large fixed table.

The VTC-800/30 models share a 137.8 x 32.3 in (3,500 x 820 mm) table. The X-axis stroke reaches 118.1 in (3,000 mm), Y-axis 31.5 in (800 mm), and B-axis swivels through 220 degrees total. This long X-stroke is the defining feature - it handles elongated aerospace skins, structural members, and rail sections that cannot physically fit on a 5-axis trunnion machine.

The SR version runs an 18,000 RPM CAT No.40 spindle at 35 kW (47 hp) for high-speed aluminum and composite machining. The HD version uses a 10,000 RPM CAT No.50 spindle for heavy-duty steel and titanium work. The SD variant adds an NC rotary table for full simultaneous 5-axis machining on cylindrical parts up to 820 mm (32.3 in) diameter.

B-axis positioning in 0.0001-degree increments enables precise angular approaches. Rapid traverse hits 50 m/min (1,969 ipm) on linear axes. The sashless door design with large viewing windows provides ergonomic operator access. The MAZATROL SmoothAi CNC manages all axis coordination with conversational and G-code programming.

The VTC concept targets parts that are too long for conventional VMCs but too small or thin for gantry machines. Aerospace wing skins, rail components, long structural brackets, and architectural metalwork are prime applications.
