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.
