FM Series Flanging
The Parmigiani FM-Series is a line of heavy-duty tank head flanging machines built for industrial fabricators who demand precision, repeatability, and long-term reliability. Designed to form the curved and flanged ends of pressure vessels, storage tanks, and industrial containers, FM-Series machines handle heads from 200 mm up to 12,000 mm in diameter, with plate thicknesses ranging from 2 mm to 80 mm and knuckle radii from 15 mm to 1,500 mm. Backed by nearly a century of forming machine expertise, these are among the most capable flanging systems available on the market.
FM-Series flangers are available in two configurations — the FM-hy for heads with a center hole, and the FM-hy wch for heads without — and support the full spectrum of head geometries used in pressure vessel fabrication, including torispherical, semi-elliptical, hemispherical, conical, and flanged flat heads. Components are sourced exclusively from top-tier global suppliers including Siemens, ABB, Bosch-Rexroth, INA, and SKF, and every machine is manufactured and inspected under strict quality standards certified to UNI EN ISO 9001:2008.
Technical Details
Standard Features
Every FM-Series flanging machine ships with a comprehensive set of standard features designed for operator efficiency, machine longevity, and production reliability:
- Electric drive on the knuckle roll, upper clamping carriage, and lower head-holding carriage — all via inverter-controlled motors
- Knuckle roll tilting and angular adjustment
- Forming rolls machined from alloy forged steel, heat treated for compatibility with stainless steel workpieces
- Flanging roll fulcrum adjustment
- Swiveling lower guide rolls (3-way adjustable), height-adjustable from the control panel
- Hydraulic cylinders on both the upper clamping and lower head-holding carriages, each adjustable in height
- Upper and lower carriage travel on maintenance-free linear bearing guide-ways driven by maintenance-free ball screws
- Rapid traverse control for fast idle positioning between passes
- Automatic centralized lubrication system
- Metal telescopic protection covers over the machine bed
- Operator safety door
- Centralized control panel with alarm panel for warnings and emergency conditions
Optional equipment includes an end edge chamfering device for weld preparation, a dedicated knuckle roll change device, and a special attachment for flanging small-diameter heads.
