Vertical Machining Center

April 7, 2011

Doosan’s new VC430 vertical machining center (VMC) features a 25-HP motor that generates up to 12,000 RPM at the spindle and 123.6 ft.-lbs. of torque. 

This VMC is equipped with a 180-degree rotating pallet table. Because the table is stationary during operation, workpieces can be loaded on one side while parts are machined on the other.  Each side of the pallet measures 28.0 by 18.7 in. with a 660-lb. load capacity. Table indexing time, including clamp and unclamp, is 5 seconds.

ISO #40 tools are housed in a 40-station, double-arm magazine with 1.3-second tool-to-tool times.  The bidirectional tool magazine automatically selects the shortest path to minimize out-of-cut times.

The VMC is constructed with a one-piece Meehanite® casting that’s heavily ribbed to withstand the heat and forces associated with heavy cutting conditions.  This design provides a uniform load to the guideways, ball screws, and motors, the company says.  Linear-motion guideways and high-speed servomotors enable high rapid-axis movements, with traverses of 1,574 IPM along the X and Y axes, and 1,259 IPM along the Z axis.

A 66-gal. coolant tank is isolated from the machine’s bed to prevent heat transfer and possible thermal distortion.  Flood cooling and through-the-spindle cooling are standards; a coolant chiller is optional.  Automatic lubrication to all guideways and ball screws is delivered by piston distributors that control the lubricant volume. 

The machine’s footprint is 116.5 by 93.3 in.
