Daewoo DHM-800 HORIZONTAL MACHINING CENTER

Technical Description

The 2003 Daewoo DHM-800 Horizontal Machining Center is a robust CNC machine designed for high-precision machining tasks with significant capacity and flexibility. It features a substantial 90-tool magazine, allowing for versatile and extended automated tool operation. The machine boasts a powerful 30 HP main spindle motor capable of speeds up to 6000 RPM, enabling efficient cutting performance. Its working envelope includes travel axes measuring approximately 49.2" (X), 39.4" (Y), and 39.4" (Z), facilitating machining of large workpieces. The DHM-800 supports a pallet system with a size of 31.5" by 31.5" and a pallet weight capacity of around 3500 lbs, suitable for heavy-duty applications. Equipped with a CAT 50 spindle taper, this horizontal machining center permits use of various tool sizes, with tool diameters typically ranging up to 5.3" or 9.8", a tool length capacity of around 21.7", and tool weight limits of up to 57 lbs. The tool change time is remarkably quick at approximately 2.5 seconds, enhancing productivity. Control is managed via a FANUC CNC system, known for reliability and advanced features such as rigid tapping, helical interpolation, and custom macros. Additional technical attributes include through-spindle coolant, a spindle chiller, high-pressure coolant delivery (Cooljet), a chip conveyor, and a handheld manual pulse generator for precise manual operation. Rapid traverse rates on all axes reach about 945 IPM, with cutting feed rates of 472 IPM. The machine weighs close to 39,700 lbs, reflecting its heavy-duty construction and stability for precision machining.
