OKK HM800S HORIZONTAL MACHINING CENTER

Technical Description

The OKK HM800S is a three-axis horizontal machining center designed for high-speed, precision production work. Featuring a 31.49" × 31.49" square pallet with standard pallet changer capability and dual-pallet support, this machine delivers exceptional rigidity and repeatability. The machine accommodates travel distances of 41.34" (X), 35.43" (Y), and 34.65" (Z), with rapid traverse rates reaching 2,953 ipm across all axes. The horizontal spindle utilizes a No. 50 taper and operates at speeds up to 12,000 rpm, delivering 40 hp at 30-minute rating for demanding cutting operations. The automatic tool changer (ATC) provides standard capacity of 60 tools with optional expansion to 300 tools, enabling extended unattended machining cycles. Equipped with standard index table capability and optional rotary table functionality, the HM800S accommodates complex workpiece positioning. Maximum feed rates of 1,575 ipm across all axes combined with high rigidity linear roller guides on the X, Y, and Z axes maximize cutting performance and productivity. The machine features precision palette positioning utilizing Nidec OKK's proprietary multi-clamp and taper cone systems, ensuring superior accuracy and repeatability. Advanced construction includes a rolling drive-type precision speed reducer for the arbitrary dividing table, delivering fast indexing speeds while maintaining superior structural rigidity. This combination of speed, precision, power, and rigidity makes the HM800S ideal for high-volume production runs requiring consistent quality and minimal downtime.
