Overview

The Kitamura Mycenter-HX800G is a large-format horizontal machining center built around an 800 x 800 mm (31.5 x 31.5 in) pallet, designed for precision machining of large prismatic workpieces in aerospace, energy, and heavy industrial applications. This is a substantial machine with X/Y/Z travels of 1,570 x 1,300 x 1,400 mm (61.8 x 51.2 x 55.1 in), accommodating workpieces up to 1,525 mm (60 in) diameter and 1,550 mm (61 in) height.

The 12,000 RPM 4-step gear-driven spindle on NST 50 taper (HSK-A100 optional) with 8,000 RPM option delivers up to 1,226 Nm (904.2 ft-lbf) of cutting torque — exceptional power for heavy roughing in steel, titanium, and cast iron. The gear-driven design provides consistent torque multiplication across the full RPM range without the low-end falloff of direct-drive alternatives, making the HX800G capable of both aggressive material removal and precision finishing.

Positioning accuracy of +/-0.002 mm (+/-0.000079 in) full stroke with repeatability of +/-0.001 mm (+/-0.000039 in) across the large travel range is maintained through Kitamura's hand-scraped guideways and thermal compensation system. Rapid traverse hits 60 m/min (2,362 ipm) on all linear axes. The 62-tool ATC is standard with expansion to 212 tools. At 65,400 lbs (29,665 kg), the machine provides exceptional vibration damping for consistent surface finish on large parts.

At an estimated $800,000-$1,200,000, the HX800G competes with the Okuma MA-800HII, Mazak HCN-8800, and DMG Mori NHX 8000 in the large-format HMC segment. The combination of extreme torque output, hand-scraped precision construction, and large work envelope positions the HX800G for shops machining large structural components where both power and accuracy are non-negotiable.

Strengths & Limitations

Strengths

1,226 Nm maximum spindle torque enables aggressive roughing in steel, titanium, and cast iron on large workpieces
1,570 mm X-travel and 800 mm pallet accommodate large structural components up to 60 inches in diameter
29,665 kg machine weight provides exceptional vibration damping for consistent surface finish on large parts
60 m/min rapids minimize non-cutting time across the large work envelope
Hand-scraped guideways maintain geometric accuracy across the extensive travel range
62-tool ATC expandable to 212 tools supports complex multi-operation machining without interruption

Limitations

65,400 lb machine weight requires substantial foundation engineering and floor loading capacity
70 KVA power requirement adds significant installation and operating costs
B-axis rapid of 9,000 deg/min is slower than smaller Kitamura HMCs due to the large rotary table mass
Arumatik-Mi control requires operator retraining — most large HMC operators are familiar with Fanuc or Mazatrol

Best For

Aerospace manufacturers machining large titanium and steel structural components and landing gear parts Energy sector shops producing large turbine casings, valve bodies, and pump housings Heavy equipment manufacturers requiring precision 4-sided machining of large steel and cast iron fabrications Defense contractors machining large armor plates and structural components in specialty alloys Oil and gas equipment manufacturers producing large manifold blocks and pressure vessel components

Frequently Asked Questions

01 How does the HX800G differ from the existing HX800iG?

The HX800G represents a different generation/configuration in Kitamura's lineup. The HX800G features verified specs from Kitamura's current product page: 1,570 x 1,300 x 1,400 mm travels, 1,226 Nm torque, and 65,400 lb machine weight. Contact Kitamura for specific differences between the iG and G designations in current production.

02 What foundation is required for the HX800G?

At 65,400 lbs, the HX800G requires a properly engineered reinforced concrete foundation with vibration isolation. Typical requirements include 12-18 inches of reinforced concrete with anti-vibration mounts. Consult Kitamura's installation specification document for exact foundation design requirements.

03 Can the HX800G handle Inconel and superalloy machining?

Yes. The 1,226 Nm maximum torque and 50-taper rigidity make the HX800G well-suited for superalloy machining. The massive machine weight provides vibration damping essential for interrupted cuts in hard, work-hardening materials. High-pressure through-spindle coolant is recommended.

04 How does the HX800G compare to the Okuma MA-800HII?

Both are large-format 800-pallet HMCs targeting similar applications. The Okuma offers the established OSP control and broader service network. The Kitamura provides hand-scraped construction and exceptional torque output. The Okuma is the safer choice for service; the Kitamura appeals to shops prioritizing precision and cutting power.
