Overview

The Kitamura Bridgecenter-10G is a large-format bridge-type vertical machining center with 2,540 x 1,615 x 800 mm (100 x 63.6 x 31.5 in) X/Y/Z travel, stepping up from the 8G with expanded travel in all three axes. This machine enters the realm of dedicated large-part manufacturing where only bridge-type construction can maintain the rigidity and accuracy required across a 100-inch X-stroke.

The 12,000 RPM 4-step gear-driven spindle with NST No. 50 taper (HSK-A100 optional) provides the torque needed for heavy roughing on large steel and cast iron workpieces. The expanded Y-axis at 1,615 mm (63.6 in) is a significant upgrade over the 6G and 8G models' 1,095 mm, giving operators over 5 feet of Y-travel for wide workpieces and deep-reach operations. The Z-axis also grows to 800 mm (31.5 in) for deeper cavity work.

The table measures 1,370 x 3,000 mm (53.9 x 118.1 in) with a 6,000 kg (13,227 lb) load capacity, accommodating the largest mold bases, die blocks, and aerospace structural components. Tool storage provides 40 tools standard with 60 or 80-tool options. Rapids hold at 24 m/min (945 ipm). Positioning accuracy of plus/minus 0.002 mm over full stroke with plus/minus 0.001 mm repeatability is maintained through hand-scraped surfaces across all axis lengths.

New Bridgecenter-10G machines typically price between $450,000 and $650,000. At this investment level, the 10G competes with large bridge machines from Toyoda, SNK, Nicolas Correa, and Toshiba. Kitamura's hand-scraped precision is a rare find in the 100-inch VMC class, where most competitors rely exclusively on ground and scraped surfaces without the hand-finishing that Kitamura applies.

Strengths & Limitations

Strengths

2,540 x 1,615 x 800 mm travel provides a massive 100x64x32 inch work envelope with bridge-type rigidity
1,615 mm Y-travel is a major step up from the 6G/8G models, enabling wide-part and deep-reach operations
6,000 kg (13,227 lb) table capacity handles the heaviest mold bases and structural steel assemblies
Hand-scraped mating surfaces deliver ±0.002 mm accuracy across 100 inches of X-travel — rare in this size class
50-taper 4-step geared spindle provides full-range torque for heavy steel and cast iron roughing
1,370 x 3,000 mm table accommodates multiple large workpieces or single oversized parts

Limitations

24 m/min rapids across 100 inches of X-travel result in 6+ second positioning moves at full stroke
Massive footprint requires dedicated floor space, substantial foundation preparation, and overhead crane access for installation
50 KVA power requirement demands significant electrical infrastructure investment
Price of $450-650K requires consistent large-part production volume to justify the capital

Best For

Large mold base manufacturers working on oversized automotive and industrial mold assemblies Aerospace manufacturers machining large structural panels, wing skins, and bulkhead components Die shops producing the largest progressive and transfer dies requiring 100 inches of precision travel Heavy-industry manufacturers machining large cast iron machine bases, frames, and structural weldments Shops requiring ±0.002 mm accuracy across 100 inches that only hand-scraped bridge construction can deliver

Frequently Asked Questions

01 What does a new Kitamura Bridgecenter-10G cost?

New machines typically price between $450,000 and $650,000 depending on options, tool capacity, and spindle configuration. Foundation preparation and rigging for a machine this size can add $20-50K to the installed cost.

02 How does the 10G differ from the 8G?

The 10G adds 500 mm (20 in) of X-travel (100 in vs 80 in), 520 mm (20 in) of Y-travel (63.6 in vs 43.1 in), and 90 mm (3.5 in) of Z-travel (31.5 in vs 28 in). The table grows to 1,370 x 3,000 mm with 13,227 lb capacity. The expanded Y and Z axes are as significant as the longer X-stroke.

03 What foundation is required for the 10G?

A machine of this size typically requires a reinforced concrete foundation designed to support the machine weight plus maximum workpiece load plus dynamic cutting forces. Kitamura provides foundation specifications based on site conditions. Most installations require 12-18 inches of reinforced concrete with isolation from adjacent machine foundations.

04 Is the 10G available in a #40 taper version?

The Bridgecenter-10G is typically offered only in the 50-taper configuration, as the machine's size class and intended workload demand the torque and rigidity that a 50-taper spindle provides. For high-speed finishing applications on large parts, the 12,000 RPM geared spindle provides adequate speed for most materials.
