The PMI-18 is a compact semi-automatic choice for straight cutoff of aluminum extrusions and profiles. Its 18-inch blade runs at 3,200 RPM, while an air-over-oil feed system lets the operator tune blade advance for the section being cut. A 4.33 x 11.81-inch envelope covers common nonferrous profile work without the footprint or complexity of an automatic indexing machine.
PMI-18 Upcut Saw Features:
The PMI-18 is a semi automatic aluminum upcut saw built around controlled 90° cutting without the additional complexity of integrated CNC material indexing. The operator positions the stock and establishes the required length, while the machine handles clamping and the upcut stroke. This configuration works well for fabrication cells and job shops where part dimensions change frequently and fully automatic material positioning is not required.
A 7.5 HP motor drives the blade at 3,200 RPM, giving this 18 inch extrusion cutoff saw the cutting performance needed for aluminum profiles and other nonferrous sections. Air-over-oil feed allows blade advancement to be adjusted for the workpiece, providing greater control when moving between thin-wall extrusions and heavier sections rather than forcing every profile through the same cutting rate.
Built as a straight cut nonferrous saw, the PMI-18 keeps the cutting process focused on square 90° ends for extrusions, blanks, and profile sections. When repeat-length work increases, the saw can be paired with PMI GO2 stop or pusher systems to reduce manual measuring and add material-positioning automation without replacing the underlying cutting platform.

The Pat Mooney PMI-18 Upcut Saw is a semi-automatic straight-cut upcut saw for aluminum extrusion and other non-ferrous profiles. Its operating format and working range define where it fits within aluminum and non-ferrous cutoff production.
The machine uses an 18-inch blade, 7.5-hp motor, 3,200 rpm speed, air-over-oil feed, and adjustable vertical and horizontal clamping. Published capacity is 4.33 inches high by 11.81 inches wide. Final machine selection depends on the complete material range, profile or plate geometry, finished length, tolerance, production volume, blade requirements, clamping, material support, and part handling.
Common applications include:
The operator positions the material and initiates the powered upcut stroke.
The 4.33 × 11.81-inch range covers common small and medium profiles.
Adjustable feed controls blade entry through changing sections.
Go2 stop and pusher systems can add digital positioning or automatic advancement.
The powered saw-head cutting stroke is semi-automatic. Material length is positioned manually unless an optional stop or pusher system is added.
Maximum capacity is 4.33 inches high by 11.81 inches wide with an 18-inch blade.
No. It is a fixed 90-degree straight-cut saw.
The CNC Auto adds a built-in servo pusher and touchscreen-controlled automatic length production. The semi-automatic PMI-18 relies on operator positioning or an optional external system.
Short runs, changing cut lengths, prototypes, maintenance parts, and profile work where automatic batch indexing is not required are practical candidates.
