Overview
The Kitamura Mycenter-HX1000G is one of the largest horizontal machining centers in Kitamura's lineup, built around a 1,000 x 1,000 mm (39.4 x 39.4 in) pallet for machining large structural components in aerospace, energy, and heavy industrial applications. With X/Y/Z travels of 2,040 x 1,350 x 1,370 mm (80.3 x 53.1 x 53.9 in), the HX1000G handles workpieces up to 2,050 mm (87 in) in diameter and 1,550 mm (61 in) in height.
The 8,000 RPM 4-step gear-driven spindle on NST 50 taper with a 12,000 RPM option delivers the rigidity and torque needed for heavy-duty material removal in steel, titanium, and cast iron. The gear-driven design provides consistent torque multiplication at low RPMs, essential for the large-diameter face milling and heavy boring operations common on parts of this scale. Kitamura's Super Smooth Surface control technology ensures fine surface finishes even on large contoured surfaces.
Positioning accuracy of +/-0.002 mm (+/-0.000079 in) full stroke with repeatability of +/-0.001 mm (+/-0.000039 in) across more than 2 meters of X-travel is remarkable for a machine of this size, achieved through hand-scraped guideways and comprehensive thermal compensation. Rapid traverse at 36 m/min (1,417 ipm) is moderate by HMC standards but appropriate for the machine's mass. The 150-tool ATC (expandable to 200 tools) supports complex multi-operation programs.
At an estimated $1,200,000-$1,800,000, the HX1000G competes with the Okuma MB-10000H, Mazak HCN-10800, and DMG Mori NHX 10000 in the large-format HMC segment. This is a significant capital investment targeting manufacturers with consistent large-part production volume in aerospace, power generation, and heavy industrial applications.

Strengths & Limitations
Strengths
- 2,040 mm X-travel and 1,000 mm pallet accommodate very large structural components up to 87 inches in diameter
- 150-tool standard ATC eliminates tool change interruptions on complex multi-operation programs
- +/-0.002 mm positioning accuracy across 2+ meters of travel is exceptional for a machine of this scale
- 4-step gear-driven spindle provides consistent torque for heavy face milling and boring operations
- Super Smooth Surface control technology delivers fine finishes on large contoured surfaces
- Hand-scraped guideways provide long-term accuracy retention on this large-scale platform
Limitations
- 36 m/min rapids are slower than smaller Kitamura HMCs due to the massive moving components
- 85 KVA power requirement and large footprint demand significant facility infrastructure
- 6.7-second tool-to-tool change time is slower than smaller HMC classes
- B-axis rapid of 4,000 deg/min is slow for repositioning between faces on complex parts

Frequently Asked Questions
01
The machine requires substantial facility infrastructure: 85 KVA three-phase power, a properly engineered reinforced concrete foundation rated for the machine's considerable weight, adequate ceiling height for crane access during installation and pallet loading, and sufficient floor space for the large footprint plus chip conveyor and coolant systems.
02
Large structural components often require 50-100+ different tools for roughing, semi-finishing, finishing, drilling, tapping, and boring operations. The 150-tool standard magazine (200 optional) eliminates the need for mid-program tool loading, enabling uninterrupted machining of complete complex parts in a single setup.
03
At 36 m/min versus 60 m/min on smaller models, the reduced rapids reflect the significantly greater mass of the moving components on a 1,000 mm pallet machine. The slower rapids also help maintain positioning accuracy across the 2+ meter X-travel range. The larger tool magazine and single-setup machining capability offset the rapids difference in total cycle time.
04
Both are large-format 1,000-pallet HMCs. The Okuma offers the OSP control with broader operator familiarity and a larger global service network. The Kitamura provides hand-scraped construction and a larger standard tool magazine (150 vs typical 60-80 tools). Both deliver comparable accuracy. Choose the Okuma for service support; the Kitamura for precision and tool capacity.
