Added Rotary Tables

April 1, 2010

The recently introduced DNM vertical machining centers from Doosan are now equipped with factory-installed Tsudakoma TN161 or TN201 rotary turning tables.

The TN models incorporate specially designed, double-lead worm gears that mesh the full length of the teeth.The machine also features a patent-pending pneumatic clamping device for added power.According to Doosan, these features improve indexing speed by 50 percent and clamping force by 250 percent, and result in faster cycle times and higher accuracy, even when machining far from the tilting axis.

Tsudakoma rotary tables are standard on Doosan’s DNM400-31iA5 vertical machining center with a 36.2-in. by 17.1-in. loading area, and the DNM500-31iA5 vertical turning center with a 47.2-in. by 21.2-in. capacity.Both models are powered by a 30-HP spindle motor capable of driving CAT 40 tools at speeds up to 15,000 RPM and generate up to 1,655 lbs. of thrust along the X and Y axes and 3,611 lbs. along the Z.

The table is fully supported by the saddle in all positions, with no table overhang, and all axes have linear-motion guideways.
