The NISHIJIMAX NHC-80 is a high-speed circular saw built for efficient production cutting of small-diameter steel bar and tube. With capacity for round stock up to 3.149 inches (80 mm), it combines a 10.5 HP saw motor with servo-controlled cutting and material positioning for fast, repeatable cutoff cycles. X-axis indexing speeds up to 78 ft/min help reduce time between cuts, making the Pat Mooney NHC-80 well suited for high-volume applications where consistent part length and production efficiency are critical.
NHC-80 Series (3 inch Cutting Capacity) Features:
The Pat Mooney NHC-80 Series (3 inch Cutting Capacity) high speed production circular saw pairs a 23.622-inch single index with X-axis travel up to 78 ft/min. That speed is valuable on short, repetitive parts because the machine can reposition bar or tube quickly between cuts instead of allowing material advancement to become the limiting part of the cycle.
Round capacity reaches 3.149 inches, with square stock up to 2.362 inches. A 10.5 HP motor drives the 10.75-inch blade from 70 to 200 RPM, giving manufacturers a dedicated circular-saw platform for smaller shafts, blanks, tubing, and other ferrous components that do not require a larger NHC machine.
The NISHIJIMAX NHC-80 saw features a 45° slant cutting axis and uses an AC servo motor and ball screw to control blade movement through the work. Hydraulic horizontal and vertical clamping stabilizes the stock, while the NHC blade-guidance, chip-removal, and lubrication systems support consistent cutting during longer production runs.

The Pat Mooney NHC-80 Series is a Nishijimax high-speed carbide circular saw for automatic cutoff production on smaller-diameter bar and tube. Its configuration places the machine within a defined range of cutoff work rather than treating it as a general-purpose saw.
Published capacity ranges from 0.393 to 3.149 inches (10 to 80 mm) for round stock and 0.393 to 2.362 inches (10 to 60 mm) for square stock. The machine uses a 45-degree slant cutting axis, AC-servo and ball-screw saw-head feed, and an AC-servo and ball-screw X-axis sizer. Machine weight is approximately 6,600 pounds. Final saw selection depends on the complete stock range, material condition, cut length, tolerance, blade requirements, production rate, material handling, remnant strategy, and downstream process.
Manufacturers commonly evaluate this saw for:
The 3.149-inch maximum round capacity gives manufacturers a dedicated platform for smaller stock instead of tying up a larger saw.
The 45-degree slant saw head travels on linear rails, allowing the blade guides to remain close to the stock while directing chips away from the spindle area.
Independent control of blade speed, chip load, saw-head feed, and material indexing supports repeatable production cycles.
Horizontal and vertical clamping on both sides of the blade limits movement that can shorten blade life or reduce cut quality.
Published capacity is 0.393 to 3.149 inches (10 to 80 mm) for round stock and 0.393 to 2.362 inches (10 to 60 mm) for square stock. The actual application must also account for material grade, wall thickness, blade selection, bundle arrangement, and required cut length.
The NHC-80 concentrates its 6,600-pound structure, clamping, blade guidance, and servo control on stock up to the 3-inch class. For a steady mix of smaller bar or tube, that can provide a better process match than running every job on a higher-capacity machine.
An AC-servo motor and ball screw position the X-axis sizer. The sizer clamp indexes the bar or tube to the programmed length and retracts after the cut to protect the finished surface and blade.
Yes. Pat Mooney Saws offers load tables, chain-loading systems, exit systems, and part-diverter arrangements. The correct layout depends on bar length, bundle size, finished-part handling, and the required production rate.
The material specification, round or square size range, solid or tubular section, incoming bar length, finished cut length, tolerance, surface requirement, annual volume, loading method, and downstream handling define the application.
