The PMI-20 30 CNC is built for aluminum profiles that push beyond the working envelope of the 24-inch miter platform. Its 30-inch blade reaches 9.8 inches in height and 18.11 inches in width, while hydraulic blade feed and servo-powered ±60° head rotation give larger sections the same programmable miter capability expected in automated production.
PMI-20 30 CNC Auto Miter Upcut Saw Features:
Moving to a Pat Mooney 30 inch CNC aluminum miter saw blade is meaningful when the workpiece itself becomes the limiting factor. The PMI-20 30 CNC accepts aluminum and nonferrous sections up to 9.8 inches high and 18.11 inches wide, giving window, structural profile, transportation, and extrusion operations room for parts that do not fit comfortably on smaller upcut equipment.
A 10 HP motor drives the 30-inch blade at 1,500 RPM. Instead of the air-over-oil feed used on the 24-inch model, this machine uses fully hydraulic cutting-rate control. That distinction matters on larger cross sections because the operator can manage blade advance through the material while the vertical and horizontal clamps stabilize the profile.
The saw head on the hydraulic feed aluminum upcut saw rotates under servo power through 60° in either direction. Combined with automatic material pushing and touchscreen control, the machine can address repeat miter parts without turning every angle change into a manual setup. As a result, the large profile automatic miter saw is ideal for machine shop production rather than occasional angled cuts.

The Pat Mooney PMI-20 30 CNC Auto Miter Upcut Saw is a fully automatic large-capacity upcut miter saw for aluminum and non-ferrous profiles. Its configuration places the machine within a defined range of cutoff work rather than treating it as a general-purpose saw.
A 30-inch blade and 10-hp motor provide a published maximum envelope of 9.8 inches high by 18.11 inches wide. The head rotates 60 degrees left and right under servo control, while the automatic pusher, touchscreen, fully hydraulic feed, and adjustable clamping manage the cycle. Final machine selection depends on the complete material range, section geometry, finished length, tolerance, production volume, blade requirements, clamping, material support, and part handling.
Common applications include:
The larger blade expands height and width capacity for profiles beyond the PMI-20 24 range.
Hydraulic saw-head feed provides controlled blade entry through large non-ferrous sections.
Servo head positioning handles left and right miters without manual angle setup.
Material length is indexed as part of the programmed production sequence.
Maximum capacity is 9.8 inches high by 18.11 inches wide at the published reference position. Miter angle and profile orientation reduce the available envelope.
The 30-inch model increases the envelope from 7.87 × 14.6 inches to 9.8 × 18.11 inches, raises motor power from 7.5 to 10 hp, and uses fully hydraulic saw-head feed.
The saw-head miter rotation is servo controlled through 60 degrees left and right, and the built-in pusher controls material indexing for automatic cut lengths.
The published 1,500 rpm speed corresponds with the larger 30-inch blade. Cutting performance still depends on blade tooth geometry, material alloy, wall thickness, and feed rate.
The complete cross-section, longest and shortest cut, miter sequence, wall thickness, alloy, finish, allowable marking, clamping zones, scrap allowance, and required pieces per shift govern the setup.
