Doosan HC400-II HORIZONTAL MACHINING CENTER

Technical Description

The 2017 Doosan HC400-II Horizontal Machining Center is a high-performance, compact CNC machine designed for precision and productivity in metalworking. It features a robust CAT #40 Big Plus spindle taper with a direct drive 25 HP motor capable of reaching spindle speeds up to 12,000 RPM, enabling efficient high-speed cutting operations. The machine provides substantial travel axes with X-axis at 23.6 inches (600 mm), Y-axis at 22 inches (560 mm), and Z-axis at 22.2 inches (565 mm), suitable for a wide range of workpiece sizes with a maximum table load of approximately 882 lbs (400 kg). It incorporates a dual-pallet changer system, each pallet measuring 15.7" x 15.7" (398.78 mm x 398.78 mm), equipped with full 4th axis rotary indexing for enhanced machining flexibility. The HC400-II includes a 60-position automatic tool changer (ATC), supporting rapid tool changes and minimizing downtime. Rapid traverse and cutting feedrates reach up to 1575 inches per minute (40 m/min), ensuring high-speed, efficient material removal. The machine's control system is a Fanuc i Series CNC offering advanced features such as rigid tapping, spindle orientation, and AI contour control, enhancing precision and ease of programming. Additional functionalities include coolant-through-spindle with programmable coolant, chip conveyor, and a Renishaw probe interface for on-machine inspection. The machine’s substantial weight of approximately 26,800 lbs contributes to its rigid structure, minimizing vibrations during machining to improve surface finish and accuracy. Overall, the Doosan HC400-II is engineered for versatility, durability, and high productivity in horizontal machining applications.
