Dual Spindle Design of Vertical Machining Center Increases Productivity

The DMP 500/2SP from Doosan Machine Tools is equipped with two spindles and two automatic-tool-changers (ATC). Compared to single-spindle machining centers, the DMP 500/2SP doubles productivity by machining two parts simultaneously and by reducing work loading, unloading and idle times. The company says that the machine is highly productive, compact and reliable. For reduced setup times, the right spindle features a W-axis adjustment of 20 mm (0.8"), making it possible to compensate for any variability in fixture heights between spindles.

The machine center has 12,000-rpm direct drive spindles with 87 lb-ft of torque. Features like 8,000-rpm spindles with 211 lb-ft of torque are optional. The load capacity (1,763 lbs) and table size (47" x 20.5") accommodate a variety of workpieces and fixtures. Together with the 20.5"-Y axis stroke, the load capacity and table size offer a machining space that is well-suited for a range of parts. The machine comes with dual 24-tool capacity magazines. Features like 30-tool and 40-tool magazines are optional. The dual ATCs boast 1.7-second tool-to-tool times, which keeps the tools in the cut longer.
