Overview

The Kitamura Mycenter 3XiG is a precision-class 40-taper vertical machining center from a Japanese manufacturer that has quietly built one of the strongest reputations in the VMC market for accuracy and long-term reliability. Kitamura hand-scrapes the mating surfaces on their machines — a time-intensive process that most manufacturers abandoned decades ago — which contributes to the exceptional geometric accuracy and positional repeatability these machines are known for. The 3XiG sits in the mid-size VMC category with 760 x 455 x 460 mm (29.9 x 17.9 x 18.1 in) of travel.

The 15,000 RPM dual-contact spindle (Big Plus) delivers 13.4 kW (18 hp) through a 2-speed geared head, producing up to 182 Nm (134 ft-lbf) of torque. That geared head is significant — it gives the 3XiG more low-end torque than most direct-drive 40-taper spindles, making it surprisingly capable in steel and stainless despite the moderate horsepower rating. The combination of high speed and high torque makes it genuinely versatile across materials.

The 30-tool side-mount ATC delivers 3-second chip-to-chip tool changes, and rapids of 5,000 mm/min (197 ipm) on X/Y and 3,600 mm/min (142 ipm) on Z are moderate by modern standards. The table measures 900 x 410 mm (35.4 x 16.1 in) with Kitamura's Arumatik-Mi CNC control — a Mitsubishi-based platform that's straightforward to learn but less common than Fanuc in most shops. At 5,689 kg (12,540 lb), the machine has adequate mass for its envelope size.

Kitamura machines command a premium over Haas and compete more directly with Okuma and Mori Seiki on precision and build quality. New Mycenter 3XiG machines typically price in the $80,000-$110,000 range. The used market is strong, with these machines known for holding accuracy for 15-20+ years. Shops that prioritize precision, surface finish, and long-term value over raw speed tend to gravitate toward Kitamura.

Strengths & Limitations

Strengths

  • Hand-scraped mating surfaces deliver geometric accuracy and precision that most competitors achieve only with higher-end platforms
  • 15,000 RPM geared spindle with 182 Nm torque provides both high speed for aluminum and strong low-end grunt for steel
  • Dual-contact Big Plus spindle interface improves rigidity and reduces runout versus standard CAT 40
  • 3-second chip-to-chip tool changes minimize non-cutting time in multi-tool operations
  • Known for exceptional long-term accuracy retention — machines commonly hold spec for 15-20 years
  • 30-tool ATC provides good capacity for complex multi-feature parts

Limitations

  • Arumatik-Mi control is Mitsubishi-based and less common than Fanuc — retraining required for Fanuc-experienced operators
  • Rapid traverse at 197 ipm is slow by modern standards; machines like the YCM NXV560A run at 1,890 ipm
  • 760 mm (30 in) X-travel puts it at the smaller end of mid-size VMCs — the Haas VF-2 matches it for less money
  • Kitamura's dealer network in North America is limited compared to Haas, Mazak, or Okuma
  • Price premium of $20-40K over a comparably sized Haas requires a workload that values precision over cost

Best For

Precision job shops producing tight-tolerance parts in aerospace, medical, and defense applications Mold and die shops requiring excellent surface finish and geometric accuracy on cavity and core work Shops where long-term machine accuracy matters more than initial acquisition cost Mixed-material work in aluminum, steel, and stainless where the geared spindle's torque range proves valuable Manufacturers producing parts with tolerances under ±0.005 mm (±0.0002 in) that demand repeatable precision

Frequently Asked Questions

01 What does a new Kitamura Mycenter 3XiG cost?

New machines typically price between $80,000 and $110,000 depending on options. Used Kitamura Mycenters hold their value exceptionally well due to their reputation for long-term accuracy, with 10-15 year old machines often selling for $30,000-$50,000.

02 Why does Kitamura hand-scrape their machines?

Hand-scraping creates a precise fit between mating surfaces (like the ways and saddle) that cannot be achieved with grinding alone. The resulting oil retention pattern and surface-to-surface contact quality contribute to the machines' exceptional geometric accuracy and long-term precision retention.

03 What is the Arumatik-Mi control?

The Arumatik-Mi is Kitamura's proprietary CNC control built on a Mitsubishi platform. It's a capable, modern control with conversational programming and standard G-code support. The main downside is that it's less common than Fanuc, so operators may need retraining.

04 How does the 3XiG compare to the Haas VF-2?

The Haas VF-2 offers similar travel for roughly $30-40K less. The Kitamura wins on precision, spindle torque (geared head), and long-term accuracy retention. The Haas wins on price, dealer network, and control familiarity. Choose the Kitamura if your work demands tight tolerances; choose the Haas if value and support are priorities.
