Overview
The Kitamura Mycenter-H500i is a 500mm pallet horizontal machining center that brings Kitamura's precision manufacturing philosophy — including hand-scraped axis surfaces and direct-drive rotary table — to the productive workhorse HMC segment. Designed to compete with the Mazak HCN-5000, Okuma MB-5000HII, and DMG Mori NHX 5000, the H500i differentiates on long-term accuracy, surface finish quality, and the reliability of Kitamura's precision assembly methods.
The H500i offers X/Y/Z travels of 730 × 730 × 730mm around a 500 × 500mm square pallet, with a direct-drive B-axis rotary table providing 0.001° indexing resolution and full 4th-axis CNC capability. The direct-drive table eliminates gear backlash and improves B-axis positioning repeatability compared to worm-gear driven competitors, giving the H500i an accuracy edge that matters for tight-tolerance prismatic parts in aerospace and hydraulics. Maximum workpiece capacity is 800mm diameter by 900mm height at 600kg.
Power comes from a 15,000 rpm 40-taper Big Plus spindle producing 22 kW. Kitamura applies its hand-scraping process to the spindle head, column, and bed mating surfaces, creating the high-contact-area fit that maintains axis straightness and parallelism over years of production use. The 50-tool ATC supports complex jobs with large tool arrays. Rapids reach 60 m/min across all three linear axes.
The Mycenter-H500i's Arumatik-Mi CNC includes Kitamura's thermal compensation algorithms, high-speed servo tuning, and standard support for AICC (AI Contouring Control) for smooth toolpath execution during complex prismatic programs. Shops running high-mix production of precision housings, valve bodies, and aerospace structural components will find the H500i's combination of accuracy and productivity compelling at its price point of approximately $450,000 to $650,000 new.

Strengths & Limitations
Strengths
- Direct-drive B-axis eliminates gear backlash for superior rotary positioning accuracy on 4th-axis features
- Hand-scraped mating surfaces deliver long-term geometric stability beyond what ground-only surfaces provide
- 730mm cube work envelope and 500mm pallet handle a wide range of mid-size prismatic production parts
- 60 m/min rapids and 50-tool ATC maximize spindle utilization on complex multi-operation workpieces
- Big Plus dual-contact spindle improves tool rigidity and surface finish at high spindle speeds
Limitations
- Arumatik-Mi CNC requires operator retraining for shops standardized on Fanuc or MAZATROL
- Kitamura's PALLETECH-equivalent FMS automation infrastructure is less developed than Mazak's or Okuma's
- Premium pricing for precision advantages that general production shops may not fully utilize

Frequently Asked Questions
01
Both use 500mm pallets in a similar travel envelope. The Mazak HCN-5000 has a stronger automation ecosystem (PALLETECH FMS) and MAZATROL conversational programming. The Kitamura H500i differentiates with its direct-drive B-axis, hand-scraped precision, and Big Plus spindle for superior accuracy and long-term geometric stability. Shops that prioritize automation infrastructure favor Mazak; shops that prioritize precision favor Kitamura.
02
Direct-drive tables use a torque motor to rotate the B-axis without gears, eliminating the backlash inherent in worm-gear drives. This improves B-axis positioning repeatability and allows faster rotary indexing without the deceleration needed to compensate for gear backlash. The result is better 4th-axis feature accuracy and faster pallet rotation between faces.
03
Yes. Kitamura offers pallet pool and automation interfaces for the H500i compatible with standard pallet handling systems. The machine's interface supports integration with third-party pallet transport systems, though Kitamura's own FMS scale is more limited than Mazak's PALLETECH or Okuma's Fastems-based systems.
04
The H500i handles the full range of precision manufacturing materials — aluminum, steel, cast iron, titanium, stainless steel, and engineering alloys. The 22 kW Big Plus CAT 40 spindle provides adequate power for titanium and steel roughing at production feeds. The machine's precision construction is especially valuable for materials where dimensional accuracy and surface finish directly affect part function.
05
Yes. The H500i includes a standard 2-pallet APC that allows one pallet to be loaded and set up at the loading station while the machine cuts on the other pallet. This dual-pallet configuration is standard on all horizontal machining centers in the H-series lineup.
