Overview

The Kitamura Mycenter-HX250iG is a compact horizontal machining center built around a 254 x 254 mm (10 x 10 in) pallet platform, making it the smallest HMC in Kitamura's current lineup. Designed for high-speed, high-precision machining of small prismatic components, the HX250iG targets medical device, electronics, and small aerospace part manufacturers who need four-sided access and superior chip evacuation on parts that would otherwise require multiple VMC setups.

The machine delivers X/Y/Z travels of 305 x 305 x 330 mm (12 x 12 x 13 in) with a 15,000 RPM direct-drive spindle on an NST 30 taper, with a 30,000 RPM option for shops running high-speed aluminum or graphite electrode work. The compact footprint belies serious capability: positioning accuracy of +/-0.002 mm (+/-0.000079 in) full stroke with repeatability of +/-0.001 mm (+/-0.000039 in) places this machine in jig-bore territory for small part machining. Rapid traverse rates of 60 m/min (2,362 ipm) on all linear axes minimize non-cutting time.

The 40-tool ATC is field-expandable to 102 tools, supporting lights-out production runs on complex multi-feature parts. The 2-station APC delivers a 1.2-second table-to-table pallet change — among the fastest in any HMC class — enabling near-continuous cutting. The B-axis rotary table indexes at 108,000 degrees/min for rapid angular positioning between faces. Kitamura's hand-scraped mating surfaces on all axis guideways provide the geometric accuracy foundation that separates these machines from competing compact HMCs.

At an estimated $250,000-$400,000, the HX250iG competes with the Brother Speedio S300Xd1 and Fanuc Robodrill in the compact horizontal machining space, though Kitamura's hand-scraped precision and positioning accuracy exceed what production-oriented competitors typically deliver. The machine is ideal for shops that need HMC-class chip management and multi-face access on small, tight-tolerance components.

Strengths & Limitations

Strengths

Compact 254 mm pallet HMC provides horizontal spindle chip evacuation and 4-face access for small precision parts
1.2-second table-to-table pallet change is among the fastest in any HMC class for near-continuous cutting
30,000 RPM optional spindle enables high-speed aluminum and graphite electrode machining on NST 30 taper
60 m/min rapids on all axes minimize positioning time between features on complex small parts
40-tool ATC expandable to 102 tools supports lights-out production without tool change interruptions
Hand-scraped mating surfaces deliver jig-bore-class positioning accuracy rare in compact HMCs

Limitations

254 mm pallet severely limits workpiece size — only suitable for small prismatic components
NST 30 taper restricts tool selection and limits heavy cutting capability versus 40-taper machines
Arumatik-Mi control requires retraining for operators accustomed to Fanuc or Siemens platforms
Kitamura dealer network in North America is narrower than Brother or Fanuc for comparable compact HMCs

Best For

Medical device manufacturers producing small implants and instruments requiring multi-face precision machining Electronics and connector manufacturers needing 4-sided access on small prismatic housings Small aerospace component shops machining tight-tolerance fittings and brackets Precision job shops seeking HMC chip management on small parts without large machine footprint Mold shops machining small electrodes and inserts where accuracy and surface finish are paramount

Frequently Asked Questions

01 What makes the HX250iG different from a compact VMC for small parts?

The horizontal spindle orientation allows chips to fall away from the part by gravity, reducing chip re-cutting. The B-axis rotary table provides 4-sided access in a single setup, eliminating repositioning errors. For small prismatic parts requiring features on multiple faces, the HX250iG produces more accurate results in fewer setups than a VMC approach.

02 How does the 30,000 RPM option benefit small part machining?

The 30,000 RPM spindle enables high-speed machining strategies on aluminum, graphite, and soft metals where small tool diameters require high spindle speeds to achieve optimal surface speeds. For medical and electronics applications using micro-endmills, the higher RPM capability significantly improves cycle times and surface finish.

03 Can the HX250iG handle steel and stainless work?

The NST 30 taper limits heavy cutting loads, but the machine handles light-to-moderate steel and stainless work on small parts. For heavy roughing in hard materials, the larger HX300iG or HX400iG with 40-taper spindles are more appropriate. The HX250iG excels in finishing operations and high-speed strategies on all materials.

04 How does the HX250iG compare to a Brother Speedio?

Both target high-speed small part production. The Brother Speedio is faster on pure cycle time with its production-oriented design. The Kitamura HX250iG delivers superior positioning accuracy thanks to hand-scraped construction and achieves tighter tolerances. Choose the Brother for volume production, the Kitamura for precision-critical work.
