FI40E On-Site Flange Facing Machine Sets New Standard in Portable Precision Machining   Wuxi, China – June 2025 — As industrial sectors such as oil & gas, power generation, and petrochemical refining demand faster and more accurate on-site repairs, MT Portable Machine's FI40E On-Site Flange Facing Machine is redefining how critical sealing surfaces are restored in the field. Engineered for durability, portability, and micron-level accuracy, the FI40E offers the perfect combination of performance and field reliability. The FI40 series is designed for internal mounting, targeting flanges from 6 to 40 inches (153–1000 mm) in diameter, with an ID mounting range of 145–910 mm. A 102 mm (4") tool post travel supports comprehensive facing and boring operations, while six continuous feed rates allow operators to meet ASME B16.5 gramophone finish requirements—including flat face (FF), raised face (RF), ring-type joint (RTJ), and complex groove profiles such as V-grooves and lens rings.   Customers can choose between two drive configurations:   FI40P: Powered by a Modec pneumatic motor (2.2 Hp / 1.7 kW), delivering 10–33 rpm at 1.8 m³/min @ 0.6 MPa—ideal for ATEX and explosive work zones.   FI40E: Driven by a Panasonic servo motor (2.0 Hp / 1.5 kW), offering variable speeds from 0–40 rpm for precision control in workshop or plant shutdown settings.   What makes the FI40E flange facing machine stand out in the field machining world is its premium mechanical foundation. It incorporates NSK high-precision bearings and a hardened "V" linear guide system to ensure low-vibration, high-accuracy cutting even in extended operations. The 360° rotating tool post provides unmatched flexibility for machining sealing grooves and custom surface profiles.   Setup is quick and accurate thanks to three quick-set base options, each featuring micro-adjustable jaws for perfect centering. Whether the flange is horizontal, vertical, or upside down, the FI40’s low center of gravity ensures machining stability. Its modular frame design enhances portability and ease of transport.   The FI40E unit weighs 350 kg and is shipped in a rugged steel storage crate (1250×640×775 mm), designed to withstand harsh site conditions. A waterproof, impact-resistant case protects the machine during transport and long-term storage.   Lisa Sun, Technical Director at MT Portable Machine, commented: “Our clients rely on machines that reduce downtime and deliver consistent results. The FI40E flange facing tool meets those needs—backed by intelligent design, industrial-grade components, and a field-proven track record.”   Field-tested in refineries, chemical plants, offshore rigs, and nuclear stations, the FI40E continues to prove its value as a go-to solution for on-site flange resurfacing, weld overlay repair, and precision finishing. It blends portability, ruggedness, and CNC-grade accuracy—making it a top-tier choice for mission-critical maintenance.

On-Site Flange Restoration with FI40E Flange Facer – Precision Machining in Action The image shows one of our latest on-site machining projects successfully completed by MT Portable Machine’s service team. The task involved the precise restoration of a damaged flange sealing face at an industrial facility. Due to corrosion and mechanical wear, the sealing surface no longer met operational standards and required immediate attention. Our team was dispatched with the FI40E flange facer, a proven performer in field machining environments, and the repair was completed with full satisfaction from the client. The FI40E flange facer is one of MT’s most versatile and widely adopted models. With a machining range of 153mm to 1000mm, it is suitable for approximately 70% of common flange sizes used in the industry. Its dual-direction automatic feed system—both radial and axial—ensures that the tool path adheres strictly to the ASME B16.5 spiral serration standard, which is critical for proper gasket seating and leak prevention. This feature allows for precision-controlled surface finishes, whether flat, raised, or RTJ sealing faces. What sets MT apart is the continuous evolution of our equipment through real-world feedback. The FI40E, like all our models, has been refined and enhanced through countless hours of actual field operations. From petrochemical plants to pressure vessel manufacturers, our machines have proven their reliability, rigidity, and ease of use under the most demanding conditions. The feedback we receive from technicians in the field directly influences our R&D and contributes to making each generation of machines better. If you are facing challenges with worn or damaged flange faces, or require a dependable and precise flange facer for your operations, MT Portable Machine has the right solution. With a robust inventory and rapid delivery capabilities, we support both domestic and international customers with equipment and technical services tailored to their needs.

KOBELCO Achieves OEM-Level Precision with FI40E On-Site Flange Facing Machine   Osaka, Japan – June 2025 — Precision flange surfaces are vital in compressor systems, and KOBELCO, a global leader in industrial compressors, recently enhanced its assembly line by integrating the FI40E on-site flange facing machine from MT Portable Machine. Designed for high-accuracy in-situ flange machining, the FI40E played a pivotal role in meeting the tight sealing requirements for KOBELCO's large-scale compressors.   KOBELCO’s compressors serve the most demanding sectors—LNG, petrochemical, and high-pressure gas transmission—where flange face integrity directly impacts system performance. To avoid disassembly or production delays, KOBELCO turned to on-site machining, selecting MT’s FI40E flange facing solution for its portability, rigidity, and ASME/JIS-compliant finish quality.   The FI40E supports a flange machining diameter range from 6" to 40" (153–1000 mm) and is equipped with a Panasonic servo motor that offers variable speed control, six automatic feed settings, and tight flatness tolerances. During a four-day operation at the Kobe facility, MT’s service team machined suction and discharge nozzle flanges on multi-stage axial compressors. The finished surfaces achieved a roughness of Ra 3.2 or better, and a flatness within 0.05 mm, surpassing both ASME and JIS standards.   “The FI40E delivered flawless results. Its tool post rigidity ensured stable, chatter-free cuts, and the adjustable feed helped us meet multiple sealing profiles,” noted Mr. Tanaka, Senior QA Engineer at KOBELCO.   Beyond supplying the equipment, MT Portable Machine provided full engineering support, including onsite setup, tooling advice, and operator training. The modular design allowed for flexible mounting in both horizontal and vertical orientations, maximizing efficiency on the factory floor.   “We designed the FI40E to meet the strictest OEM requirements in real production environments,” said Eason Wang, Technical Director at MT. “This project with KOBELCO demonstrates that our on-site flange facing solutions match factory-level accuracy—without moving the workpiece.”   As industrial systems grow larger and downtime becomes costlier, companies like KOBELCO are embracing portable, precision-driven machining technologies. The FI40E is proving that you don’t have to compromise accuracy for mobility.
