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.
