Overview
The Kitamura Mycenter-5XF is a large-envelope simultaneous 5-axis machining center designed for complex aerospace, energy, and die-mold parts that exceed the capacity of compact trunnion-table machines. With X/Y/Z travels of 1,050 × 600 × 600mm and a 630mm diameter trunnion table, the 5XF handles substantial workpieces while maintaining the precision and surface finish quality that Kitamura is known for across its Mycenter line.
At the heart of the 5XF is Kitamura's precision-ground, hand-scraped spindle and axis mating surfaces — a manufacturing discipline that gives the machine exceptional geometric accuracy and long-term repeatability that sets Kitamura apart from competitors at similar price points. The standard 15,000 rpm Big Plus CAT 40 spindle delivers 22 kW of cutting power, with an optional 20,000 rpm direct-drive high-speed spindle for aluminum aerospace structural work. The A-axis trunnion tilts from -120° to +30° and the C-axis rotates continuously through 360°, enabling full simultaneous 5-axis contouring with RTCP.
Kitamura's Arumatik-Mi CNC control provides RTCP (Rotary Tool Center Point) control for simultaneous 5-axis programs, direct-drive rotary axis servo for fast and accurate A/C axis response, and built-in thermal compensation to maintain part accuracy across extended production cycles. A 48-tool ATC is standard, with optional expansion to accommodate complex aerospace programs requiring large tool libraries.
The Mycenter-5XF competes with the Makino D800, Mazak VARIAXIS i-700, and DMG Mori DMU 85 monoBLOCK in the large-envelope 5-axis class. Kitamura's hand-scraped precision and Big Plus spindle rigidity are key differentiators for shops machining hard materials and demanding tolerances. New pricing typically ranges from $550,000 to $800,000 depending on spindle choice and options.

Strengths & Limitations
Strengths
- Large 630mm trunnion table and 1,050mm X-travel handle aerospace structural parts and large mold cavities
- Hand-scraped mating surfaces deliver exceptional long-term geometric accuracy and repeatability
- Full simultaneous 5-axis with RTCP for complex freeform surface contouring in one setup
- Big Plus dual-contact spindle taper provides superior rigidity and tool runout performance
- Optional 20,000 rpm spindle enables high-speed aluminum aerospace machining at competitive cycle times
Limitations
- Premium pricing requires strong volume or part complexity justification over 3-axis alternatives
- Arumatik-Mi control requires retraining for shops standardized on Fanuc, Siemens, or Heidenhain
- Kitamura's North American application support and dealer presence is thinner than Mazak or DMG Mori

Frequently Asked Questions
01
The 5XF accommodates workpieces up to 800mm in diameter and 600kg in weight on its 630mm trunnion table. X/Y/Z travels of 1,050/600/600mm provide the working envelope for large prismatic and curved-surface parts.
02
Both are large-envelope 5-axis machines in a similar price range. Kitamura's hand-scraping and Big Plus spindle give it a precision and rigidity edge for demanding tolerances and hard materials. The VARIAXIS i-700 offers MAZATROL SmoothAi conversational programming and deeper FMS automation integration via PALLETECH. The choice typically comes down to precision vs. automation infrastructure priorities.
03
Yes. The Arumatik-Mi CNC provides full simultaneous 5-axis contouring with RTCP (Rotary Tool Center Point) for accurate tool-tip programming during compound-axis motion. This enables complex impellers, blisks, freeform mold surfaces, and aerospace structural features.
04
The standard 5XF ships with a 15,000 rpm, 22 kW Big Plus CAT 40 spindle suited for steel, titanium, and aluminum. An optional 20,000 rpm direct-drive high-speed spindle is available for shops focused on aluminum aerospace structural work requiring high surface speed and surface finish.
05
Hand-scraping mating surfaces is a genuine precision technique that creates near-perfect contact between moving and stationary surfaces, reducing stick-slip and improving axis straightness over the machine's life. Kitamura applies this to the Mycenter-5XF's linear and rotary axis mating surfaces. The result is measurably better initial accuracy and better retention of accuracy over time compared to ground-only surfaces.
