12.6–59 Inches Flange Resurfacing Machine Large Diameter High Efficiency Flange Facing Device
ID Mount Flange Facer FI60 Application in KOBELCO Centrifugal Compressor Manufacturing
Case Introduction
KOBELCO Wuxi Compressor Co., Ltd. (KOBELCO) specializes in high-precision centrifugal compressors with stringent tolerance requirements. Large-diameter volute flanges are critical sealing interfaces; even minor surface imperfections can lead to leakage, efficiency loss, and costly maintenance.
In 2025, MT Portable Machine deployed the FI60P ID Mount Flange Facer for on-site resurfacing of these large flanges. Its reinforced spindle, modular structure, and high rigidity allowed precise machining directly on-site, eliminating heavy disassembly and ensuring minimal production disruption.
