2021 Kitamura HX-250iG with 10-Station Pallet Pool CNC Horizontal Machining Center

The Kitamura HX-250iG is a compact horizontal machining center known for its rigid Mechanite cast iron construction and hand-scraped mating surfaces — qualities that have made it a trusted fixture in precision production environments. This 2021 unit features a 15,000 RPM dual-contact BT30 spindle driven by a 15 HP motor, with travels of 12” × 12” × 13” (X/Y/Z) and rapid traverse rates of 2,362 IPM. The machine is equipped with a substantially upgraded 102-tool arm-type automatic tool changer (standard capacity is 40 tools) and a 10-station pallet pool (upgraded from standard 2 pallets), enabling extended unattended operation and high-mix production scheduling. The Kitamura Arumatik control includes Super Smooth Surface Control for fine-finish contouring work. A high-speed direct-drive full 4th axis with Heidenhain rotary encoder provides precise and responsive continuous indexing across 250 × 250 mm pallets. Probing is handled by a Renishaw spindle probe package and Renishaw laser tool setting probe, and coolant is delivered through a Kitamura CTS high-pressure thru-spindle system rated at 220 PSI and 5.5 GPM, supplemented by overhead shower flood coolant.

The HX-250iG represents a meaningful generational step forward from Kitamura’s earlier HX-250G. Where the HX-250G topped out at 12,000 RPM on its standard spindle, the HX-250iG pushes to 15,000 RPM with a dual-contact taper for improved rigidity at speed. The “i” generation introduced the Arumatik control — a purpose-built Kitamura platform that replaced the earlier Fanuc-based configurations — along with Super Smooth Surface Control for superior finish quality on complex contoured parts. Rapid traverse rates increased, thermal stability improved through updated cooling circuits and structural refinements, and the direct-drive 4th axis eliminated backlash concerns found in gear-driven predecessors. For a buyer shopping the used market, this HX-250iG with its 102-tool magazine and 10-pallet system delivers automation capacity that would cost substantially more on a new machine — a production-ready horizontal at a used price point.
