OKK HM60 HORIZONTAL MACHINING CENTER

Technical Description

The OKK HM60 Horizontal Machining Center features an X-axis travel of approximately 32 inches, Y-axis travel of 28 inches, and Z-axis travel of 31 inches, providing a substantial working envelope for versatile machining tasks. It is equipped with a robust CAT-50 spindle capable of speeds up to 8,000 RPM, driven by a 30 HP AC motor, ensuring sufficient power for heavy-duty milling operations. The machine incorporates a 40-tool Automatic Tool Changer (ATC) enabling flexible machining processes and reduced downtime. Control is managed by a reliable Fanuc 16M CNC system, supporting precision machining with a 1-degree indexing 4th axis option and direct turn style pallet change system for efficient workpiece handling. The unit features dual 24" x 24" pallets, each capable of supporting up to approximately 1,540 lbs, facilitating continuous operation through rapid pallet changes in about 6 seconds and tool changes in 5 seconds. The HM60 is designed with high-pressure through-spindle coolant, chip conveyor, coolant re-circulation, and filtration systems to maintain machining efficiency and extend tool life. Rapid traverse rates can reach up to 1,574 IPM on all axes, enabling high-speed material removal. The machine's dimensions are roughly 120" x 169" x 123" with an approximate weight of 30,864 lbs, emphasizing its heavy-duty construction for rigidity and stability during machining processes. Recent refurbishments include linear bearing replacements, tool changer adjustments, and hydraulic hose renewals to ensure reliable performance in demanding manufacturing environments.
