OKK HM-100S HORIZONTAL MACHINING CENTER

Technical Description

The OKK HM-100S is a robust 4-axis CNC horizontal machining center engineered for high-capacity production environments. Featuring dual 39.4" square pallets with a maximum load capacity of 5,512 lbs each and rapid 15-second pallet change times, this machine enables efficient multi-part machining workflows. The machine delivers XYZ travels of 55.1", 43.3", and 39.4" respectively, with spindle nose clearance ranging from 1.97" to 45.28", accommodating diverse workpiece geometries. Equipped with a CAT 50 spindle capable of 8,000 rpm and 40 hp continuous drive motor, the HM-100S generates substantial cutting forces suitable for heavy stock removal. Programmable 1-degree B-axis indexing provides full 4-axis machining capability, enabling complex multi-face operations without manual repositioning. The 60-position automatic tool changer delivers rapid tool-to-tool times of 2.5 seconds and chip-to-chip cycles of 6 seconds, maximizing spindle utilization. Linear feed rates reach 1,889 ipm with rapid traverse speeds of 4,500 mm/min across all axes. The machine integrates Fanuc CNC controls (typically 160iS-MB models), high-pressure coolant delivery through the spindle, and a chip conveyor system for extended unmanned operation. At approximately 55,000 lbs, the HM-100S provides the structural rigidity required for sustained heavy cutting applications while maintaining precision and reliability in demanding manufacturing environments.
