2007 Doosan HC-400 CNC Horizontal Machining Center

The Doosan HC-400 is a horizontal machining center with a reputation for straightforward reliability that has made it a staple in high-volume job shop and production environments. This 2007 Doosan HC-400 pairs 24-inch travels across X, Y, and Z with a 10,000 RPM CAT 40 spindle driven by a 25 HP spindle motor, delivering rapid traverse rates of 50 m/min and a full 4th-axis B-table for continuous indexing. A 40-position automatic tool changer, a two-pallet pool sized at 400 x 400 mm with a 1,100 lb pallet load capacity, T-slot pallets, and a magnetic chip conveyor round out a well-equipped cast-iron and steel production platform.

Compared to the earlier Daewoo HM-series horizontals — the direct predecessor lineage before Doosan standardized the HC-400 designation — this generation brings meaningfully faster rapids, a higher-RPM 10,000 RPM CAT 40 spindle over the older 6,000–8,000 RPM BT-40 setups, an expanded 40-tool ATC versus the smaller 20–30 pocket changers typical of the HM-400 era, a tighter control platform, and improved structural rigidity for heavier cuts. The result is more cutting time per shift, more parts per pallet, and a modern horizontal workhorse that reaches full production speed without the ramp-up headaches the earlier Daewoo horizontals carried.
