Kitamura BRIDGECENTER-6G#40 VERTICAL MACHINING CENTER

Technical Description

The Kitamura BRIDGECENTER-6G#40 is a precision vertical machining center featuring a robust double-column bridge design engineered for heavy-duty die/mold and aerospace applications. The machine accommodates workpieces up to 6,600 lbs on its 70.9" × 35.4" table, providing exceptional stability through rigid Meehanite cast iron construction with induction-hardened solid box ways. The #40 NST spindle delivers high-speed performance up to 20,000 RPM with 20 HP (30-minute rating) and utilizes a 4-step gear drive mechanism for optimal torque delivery across the speed range. Travel dimensions span 60.2" × 43.1" × 28.0" (X, Y, Z axes), with maximum rapid traverse rates of 945 ipm on all axes, enabling efficient cycle times. The machine incorporates a 40-position automatic tool changer with 2.8-second tool-to-tool and 9-second chip-to-chip change times, expandable to 60 or 80 tools optionally. Linear scale feedback on all three axes ensures positioning accuracy of ±0.000078" full stroke with ±0.000039" repeatability, meeting demanding precision requirements for complex cavity machining. The vertical spindle configuration combined with the expansive work envelope and space-efficient footprint of approximately 166 square feet makes this machine ideal for precision finishing and roughing operations on large molds and aerospace components requiring superior rigidity and repeatable accuracy.
