Overview

The Kitamura MedCenter5AX is a compact, ultra-high-speed 5-axis machining center purpose-built for medical device manufacturing, dental prosthetics, and micro-precision aerospace components. With a 30,000 RPM HSK-E40 spindle and a 170 mm (6.7 in) diameter trunnion table, this machine is designed from the ground up for small, complex parts that demand both 5-axis simultaneous contouring and sub-micron accuracy.

The machine's 254 x 330 x 330 mm (10 x 13 x 13 in) X/Y/Z travels define a deliberately compact work envelope optimized for parts measured in centimeters rather than inches. The A-axis ranges from -120 to +120 degrees (240 degrees total), while the C-axis provides continuous 360-degree rotation. Rotary axis speeds of 100 RPM (36,000 deg/min) on A and 200 RPM (72,000 deg/min) on C enable aggressive simultaneous contouring without rotary axis bottlenecks. Linear rapids reach 60 m/min (2,362 ipm) on X/Y and 50 m/min (1,969 ipm) on Z.

The 30,000 RPM integral-drive spindle delivers 18.6 kW (25 hp) through an HSK-E40 interface, providing the extreme speed needed for small-diameter tools in titanium, cobalt-chrome, zirconia, and PMMA dental materials. The 40-tool ATC (expandable to 120 tools) supports complex multi-tool programs for dental prosthetics and orthopedic implants. Positioning accuracy of plus/minus 0.001 mm with plus/minus 0.0005 mm repeatability places this machine in the precision class.

New MedCenter5AX machines typically price between $250,000 and $380,000. The machine competes with the Datron M10 Pro, GF Machining Solutions Mikron MILL S, and Kern Micro HD in the compact medical/dental 5-axis segment. Kitamura's approximately 4 x 7 foot footprint makes it practical for clean-room and lab environments.

Strengths & Limitations

Strengths

30,000 RPM HSK-E40 spindle delivers extreme speed for small-diameter tools in titanium, cobalt-chrome, and dental ceramics
±0.001 mm positioning accuracy with ±0.0005 mm repeatability provides CMM-grade precision for medical implant tolerances
240-degree A-axis and continuous C-axis enable full 5-axis simultaneous contouring for complex anatomical geometries
Compact 4 x 7 foot footprint fits in clean-room and dental lab environments
40-tool ATC expandable to 120 tools supports the extensive tooling required for complex medical/dental programs
Fast rotary axes (100/200 RPM) prevent rotary axis bottlenecks during aggressive simultaneous contouring

Limitations

254 x 330 x 330 mm travel limits the machine to small parts — not suitable for general-purpose machining
HSK-E40 tooling ecosystem is smaller and more expensive than CAT 40 or HSK-A63
170 mm trunnion table restricts workpiece diameter to approximately 150 mm with fixturing
Arumatik-Mi control requires specific training and is less common than Fanuc or Heidenhain in the medical segment

Best For

Medical device manufacturers producing orthopedic implants (knee, hip, spinal) requiring 5-axis access and sub-micron accuracy Dental labs and prosthetics manufacturers milling zirconia, PMMA, cobalt-chrome, and titanium dental restorations Aerospace micro-machining shops producing small complex components for guidance systems and instruments Watch and precision instrument manufacturers requiring 5-axis capability in a compact, high-accuracy platform Clean-room manufacturing environments where the compact footprint and precision are both critical requirements

Frequently Asked Questions

01 What does a new Kitamura MedCenter5AX cost?

New machines typically price between $250,000 and $380,000 depending on options and tool capacity (40 to 120 tools). This is competitive with other compact medical-grade 5-axis machines from Datron, GF Machining Solutions, and Kern.

02 Can the MedCenter5AX machine dental prosthetics?

Yes, the MedCenter5AX is specifically designed for dental manufacturing. The 30,000 RPM spindle handles zirconia, PMMA, cobalt-chrome, and titanium at appropriate cutting speeds. The 5-axis simultaneous capability produces full prosthetic geometries in a single setup. Dedicated dental CAM software (Hypermill Dental, WorkNC Dental) can be post-processed for the Arumatik-Mi control.

03 What is HSK-E40 and why is it used here?

HSK-E40 is a small-format hollow taper shank interface designed for high-speed spindles above 20,000 RPM. The E-type form factor is balanced for high-speed operation and provides excellent runout characteristics. It is specifically suited to the small-diameter tools (0.1-12 mm) used in medical and dental machining.

04 How does the MedCenter5AX compare to the Mytrunnion-4G?

The MedCenter5AX is smaller, faster, and more precise: 30,000 RPM vs 15,000 RPM, ±0.001mm vs ±0.002mm accuracy, but with only 10x13x13 inch travel vs 24x24x20 inch. The MedCenter is for micro-precision medical/dental work; the Mytrunnion-4G is for larger 5-axis aerospace and precision parts.
