The PIINC MFM350 Hand-Powered Mini Flange Facer is an ultra-portable flange resurfacing machine designed for on-site field machining of pipe flanges and other compatible sealing surfaces. Its compact, lightweight design allows one operator to set up the machine and begin machining within minutes, making it a practical solution for flange maintenance and repair in locations where external power sources are unavailable.
With a facing diameter range of 25.4–350 mm and a clamping range of 25.4–304.5 mm, the MFM350 is suitable for resurfacing flat-face and raised-face flanges, as well as lens-ring joint flanges. The hand-powered design eliminates the need for electric, hydraulic, or pneumatic power, allowing the machine to be used in a wide range of field conditions.
Supplied with two different lead screws providing two feed rates, the MFM350 offers flexibility for different flange resurfacing requirements. It uses standard 1/2-inch cutting tools and provides a convenient option for maintenance teams seeking a portable flange facing tool for on-site repair work.
The MFM350 is designed for convenient transportation and on-site use. With a stated weight of approximately 7–7.5 kg, it is easy to handle and suitable for field machining tasks where portability is important.
The machine operates manually using a handle drive, eliminating the need for an electrical supply, hydraulic power unit, or compressed air. This allows flange resurfacing to be performed in locations without access to external power sources.
The MFM350 can machine facing diameters from 25.4 mm to 350 mm, supporting a variety of flange sizes and suitable sealing-surface repair applications.
With a clamping range of 25.4–304.5 mm, the MFM350 accommodates a range of flange internal diameters within its specified mounting capacity.
The machine is supplied with two different lead screws that provide two feed rates. This gives operators flexibility when resurfacing different flange types and sealing surfaces.
The MFM350 is designed for on-site resurfacing of:
Raised-face pipe flanges
Flat-face pipe flanges
Lens-ring joint flanges
Its portable design makes it a useful option for restoring suitable flange sealing surfaces without transporting the component to a workshop.
The machine is designed to allow one operator to set it up and begin machining within a few minutes. This helps simplify preparation for field maintenance and flange repair tasks.
The MFM350 uses standard 1/2-inch cutting tools, providing a straightforward tooling option for flange facing operations.
