The PMI-455 A-Type packages an 18-inch blade with ballscrew/servo indexing and fully hydraulic cutting feed for automatic straight cutoff. Unlike the PMI-18 CNC’s pusher-based layout, the A-Type is configured as an integrated production saw and adds bundle/stack clamping for applications that need to process more than one section per cycle.
PMI-455 A-Type Fully Automatic Upcut Saw Features:
The PMI-455 A-Type uses a ballscrew and servo motor to position material for programmed cut lengths. This ballscrew servo indexing saw integrates material advancement directly into the automatic cutting cycle, allowing repeated 90° parts to be indexed, clamped, cut, and advanced without resetting a manual stop between pieces. The result is a more efficient workflow for recurring production runs where consistent part length is critical.
Vertical and horizontal clamping allow the PMI-455 to secure multiple compatible profiles for a common cutoff. This bundle cutting upcut saw configuration gives manufacturers another way to increase throughput when parts can be processed in stacks rather than individually. Adjustable clamping pressure also allows the workholding force to be matched more closely to the profile, helping secure the material without applying unnecessary pressure.
A 10 HP motor drives the 18-inch blade at 3,200 RPM, with cutting capacity up to 4.33 inches high and 11.81 inches wide. Fully hydraulic feed controls blade advancement through the material during the cutting cycle. Built as an automatic aluminum saw, the PMI-455 A-Type combines straight 90° cutting, automatic indexing, and controlled clamping for production work involving aluminum extrusions, profiles, bars, and other nonferrous material.

The Pat Mooney PMI-455 A-Type Fully Automatic Upcut Saw is a fully automatic 18-inch upcut saw configured for straight cutting and bundle or stack production. Its operating format and working range define where it fits within aluminum and non-ferrous cutoff production.
A 10-hp motor, 3,200 rpm blade speed, fully hydraulic feed, touchscreen, ballscrew/servo material indexing, and adjustable vertical and horizontal clamping support a 4.33 × 11.81-inch capacity. 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 clamping arrangement supports multiple profiles within the machine’s working envelope.
Material advances to the programmed length through a controlled indexing axis.
The 10-hp motor increases available power over the 7.5-hp PMI-18 DB-Type.
Hydraulic control manages the blade’s cutting stroke through changing stack conditions.
The PMI-455 retains the same published 4.33 × 11.81-inch envelope but adds a 10-hp motor, fully hydraulic feed, ballscrew/servo indexing, and standard bundle/stack cutting capability.
Vertical and horizontal clamps secure multiple profiles so several pieces can be cut in one cycle. Stack layout, profile deformation, blade tooth count, and chip clearance affect the practical bundle.
Published specifications list an 18-inch blade operating at 3,200 rpm. Blade geometry must match the alloy, section thickness, number of profiles, and finish requirement.
A ballscrew and servo system indexes the incoming material, with job settings entered through the touchscreen control.
No. It is a fixed 90-degree straight-cut machine focused on automatic production and stacked-profile processing.
