Overview
The Kitamura Jigcenter-5G is a precision jig boring and machining center that represents the pinnacle of Kitamura's accuracy-focused engineering. With positioning accuracy of plus/minus 0.001 mm (0.000039 in) over full stroke and repeatability of plus/minus 0.0005 mm (0.00002 in), the Jigcenter-5G operates at a level of precision that puts it in the same category as dedicated coordinate measuring machines. This is not a general-purpose VMC — it is a precision instrument for shops where micron-level accuracy is non-negotiable.
The 20,000 RPM 4-step gear-driven spindle with NST No. 40 taper (HSK-A63 optional) provides both high-speed finishing capability and torque multiplication through the geared head. X/Y/Z travels of 815 x 745 x 500 mm (32.1 x 29.3 x 19.7 in) provide a moderate work envelope sized for precision mold and die work. The 50-tool ATC (expandable to 100 tools) supports complex programs requiring many tools.
The table measures 780 x 1,200 mm (30.7 x 47.2 in), providing ample clamping area for mold components, jig and fixture assemblies, and precision instrument parts. Rapid traverse at 25 m/min (984 ipm) across all axes reflects the machine's precision-first design philosophy. The machine draws 45 KVA. Kitamura's hand-scraped mating surfaces, combined with advanced thermal compensation, achieve the sub-micron accuracy that defines the Jigcenter platform.
New Jigcenter-5G machines typically price between $350,000 and $500,000, competing with precision jig boring machines from Yasda, Mitsui Seiki, and SIP. The Kitamura's advantage is combining jig boring accuracy with modern machining center speed and automation — the 50-tool ATC and 20,000 RPM spindle make it a production-capable precision machine rather than a single-purpose boring mill.

Strengths & Limitations
Strengths
- ±0.001 mm positioning accuracy and ±0.0005 mm repeatability place this machine in CMM-grade precision territory
- 20,000 RPM 4-step geared spindle combines jig boring accuracy with modern machining center speed
- 50-tool ATC (expandable to 100) makes the Jigcenter a production-capable precision machine, not a single-purpose boring mill
- Hand-scraped mating surfaces and advanced thermal compensation maintain sub-micron accuracy over extended run times
- Bridge-style construction enhances rigidity and eliminates C-frame deflection at extended Y positions
- 32 x 29 x 20 inch travel provides a practical work envelope for precision mold components and jig assemblies
Limitations
- 25 m/min rapids are deliberately conservative to protect precision — not suited for high-throughput general machining
- Price of $350-500K is justified only for work requiring sub-micron accuracy that standard VMCs cannot achieve
- 815 x 745 mm travel limits the machine to small-to-medium workpieces — not for large-format parts
- Arumatik-Mi control requires specific operator training and is less common than Fanuc in most shops

Frequently Asked Questions
01
New machines typically price between $350,000 and $500,000 depending on options, tool capacity, and spindle configuration. This is competitive with dedicated jig boring machines from Yasda and Mitsui Seiki while offering modern machining center productivity.
02
The Jigcenter achieves ±0.001 mm positioning accuracy versus ±0.002 mm on standard Mycenters — twice the precision. Repeatability is ±0.0005 mm versus ±0.001 mm. This is achieved through enhanced thermal compensation, additional hand-scraping, and tighter assembly tolerances throughout the machine.
03
Yes, that is one of its primary applications. The Jigcenter-5G matches the accuracy of traditional jig boring machines while adding a 50-tool ATC and 20,000 RPM spindle for modern machining center productivity. Many shops use it to replace aging SIP, Moore, or DeVlieg jig borers.
04
For maximum accuracy, the Jigcenter-5G should be installed in a temperature-controlled environment (±1°C). While the thermal compensation system helps, ambient temperature swings will affect sub-micron accuracy. A dedicated foundation isolated from shop vibration is also recommended.
