FI40 ID Mount Flange Facer Application in KOBELCO Centrifugal Compressor Manufacturing
CASE INTRODUCTION
KOBELCO Wuxi Compressor Co., Ltd. (KOBELCO) is a leading manufacturer of centrifugal compressors, supplying high-precision equipment for industrial and energy applications worldwide. Centrifugal compressor volute flanges are critical sealing interfaces, and scratches, uneven surfaces, or minor deformations can compromise sealing performance, reduce efficiency, and pose safety risks.
In 2025, MT Portable Machine deployed the FI40 Flange Facing Machine for on-site machining of volute flange sealing surfaces. The machine’s portable, modular design and high rigidity allowed rapid setup and precise repair without dismantling heavy compressor components.
