The Mitsui Seiki HS5A is a robust 4-axis CNC horizontal machining center engineered for precision component manufacturing. Featuring a 20 hp spindle with a maximum speed of 4,500 RPM, this machine delivers consistent performance across demanding production environments. The cutting envelope spans 33.5 inches on the X-axis, 27.5 inches on the Y-axis, and 21.65 inches on the Z-axis, providing substantial workspace for complex part geometries. The machine accommodates a CAT #50 spindle taper, compatible with industry-standard tooling interfaces. Its automatic tool changer holds up to 180 tools, enabling extended production runs with minimal manual intervention and rapid tool changes. The 24.8-inch square pallet system supports rotary indexing capability, allowing multi-sided part machining in a single setup. Controlled by a FANUC 15M CNC system, the HS5A ensures repeatability with precise axis positioning and reliable cycle-to-cycle accuracy. The machine's rigid cast iron construction incorporates Mitsui Seiki's proprietary "spring memory" design, enabling consistent part quality through repeated load cycles. This horizontal machining center excels in aerospace and automotive applications where component precision and throughput are critical, delivering the reliability and accuracy required for production environments demanding both efficiency and quality assurance.
