OKK HM600 8APC HORIZONTAL MACHINING CENTER

Technical Description

The 2011 OKK HM600 8APC is a horizontal machining center engineered for precision and heavy-duty manufacturing applications. It features an X-axis travel of 30.71 inches, Y-axis travel of 29.53 inches, and Z-axis travel of 31.50 inches, accommodating large workpieces efficiently. The machine is equipped with eight pallet stations, each measuring 24.8 by 24.8 inches, allowing for high-volume, continuous operation with pallet indexing accuracy of 0.001 degrees. It supports a maximum workpiece weight of 1,540 pounds, suitable for robust industrial jobs. The spindle system includes a CAT 50 taper with a maximum speed of 12,000 RPM, powered by a 40 HP motor, delivering a strong combination of speed and torque for a variety of cutting tasks. Rapid traverse rates reach 2,126 inches per minute across the XYZ axes, enhancing machining efficiency. This HM600 is equipped with a 160-position automatic tool changer, facilitating complex multi-tool operations without manual intervention. Control is managed via the advanced Fanuc 31i-A5 CNC system, which supports Hyper HQ Mode A, auto restart, macro interrupt functions, and full B-axis contouring capabilities. Additional features include thru-spindle coolant for extended cutting tool life and an integrated chip conveyor that ensures efficient chip removal during operation. The machine’s design supports heavy-duty machining with precise control, making it suitable for aerospace, automotive, and die/mold manufacturing sectors requiring high accuracy and throughput. Overall, the OKK HM600 8APC balances rigidity, automation, and control sophistication for demanding production environments.
