Overview
The Kitamura Mycenter-4XV is a large-envelope 40-taper vertical machining center that extends Kitamura's hand-scraped precision platform into the 40-inch X-travel class. With 1,020 x 510 x 510 mm (40.2 x 20.1 x 20.1 in) X/Y/Z travel, the 4XV provides the reach to handle long parts, multi-part fixturing, and large mold plates that the smaller 2XV and 3XV cannot accommodate.
The 15,000 RPM dual-contact spindle delivers 30.6 kW (41 hp) through a direct-drive system, matching the smaller V-series machines on spindle performance while adding the longer X-axis stroke. Rapid traverse rates reach 60 m/min (2,362 ipm) — even faster than the 3XV — which is critical for minimizing positioning time on a machine with over a meter of X-travel. The 40-tool ATC with 2.2-second tool-to-tool changes provides ample capacity for complex programs.
The table measures 510 x 1,120 mm (19.7 x 44.1 in), well-proportioned for the machine's travel envelope and suitable for long parts, multi-vise setups, or large single workpieces. Positioning accuracy holds at plus/minus 0.002 mm over full stroke with plus/minus 0.001 mm repeatability across all axes — maintaining Kitamura's precision standard even with the longer travels. The Arumatik-Mi Pro control provides modern processing capability with high-speed look-ahead.
New Mycenter-4XV machines typically price between $110,000 and $150,000, positioning them against the Haas VF-4, Okuma GENOS M560-V, and DMG Mori CMX 800 V. The 4XV's combination of 40-inch travel, genuine precision, and 41 hp spindle power makes it particularly compelling for shops that need both reach and accuracy.

Strengths & Limitations
Strengths
- 1,020 mm (40 in) X-travel extends Kitamura's hand-scraped precision platform into the large VMC class for longer parts and multi-vise setups
- 60 m/min rapid traverse is among the fastest in the 40-taper VMC category, critical for reducing non-cutting time over the long X-axis
- 41 hp dual-contact spindle delivers strong cutting performance for both high-speed aluminum and aggressive steel roughing
- Hand-scraped mating surfaces maintain ±0.002 mm positioning accuracy across the full 40-inch X-stroke
- 40-tool ATC handles complex multi-feature programs without tool management compromises
- Arumatik-Mi Pro control with advanced look-ahead supports smooth surface finish at high feed rates
Limitations
- Arumatik-Mi Pro control is Mitsubishi-based and less familiar to shops standardized on Fanuc or Siemens
- 510 mm (20 in) Y-travel is moderate for a machine with 40 inches of X — competitors like the Haas VF-4 offer similar Y for less money
- Price premium over Haas VF-4 ($65-80K) is substantial and requires precision-oriented workload to justify
- Limited North American Kitamura dealer network can mean longer service response times in some regions

Frequently Asked Questions
01
New machines typically price between $110,000 and $150,000 depending on options. This is roughly double the price of a comparable Haas VF-4 but delivers significantly better precision, faster rapids, and Kitamura's hand-scraped build quality.
02
The Haas VF-4 offers similar 40-inch X-travel for roughly $65-80K. The Kitamura 4XV wins on precision (±0.002mm vs ±0.005mm), rapid traverse (2,362 ipm vs 1,000 ipm), and spindle power (41 hp vs 20-30 hp). Choose the Kitamura if your work demands tight tolerances and fast cycle times.
03
Yes, the 510 x 1,120 mm table has ample room for a 4th axis rotary table. The Arumatik-Mi Pro control supports 4th axis programming. The 40-inch X-travel provides clearance for rotary indexing of longer parts.
04
Yes, the 4XV is well-suited to mold and die work. The hand-scraped accuracy and 15,000 RPM spindle deliver excellent surface finish on cavity and core details. The 40-inch X-travel accommodates large mold plates. Through-spindle coolant is available as an option for deep cavity work.
