Medium-diameter ferrous cutoff work is the focus of the NISHIJIMAX NHC-130. With 5.118-inch (130 mm) capacity, the machine is sized for bar, billet, tube, and pipe that require automatic length positioning and a rigid circular-saw process. Servo-driven cutting and sizing axes, hydraulic workholding, precision blade guidance, and automatic lubrication give the NHC-130 the production hardware needed for recurring cutoff jobs.
NHC-130 Series (5.118 inch Cutting Capacity) Features:
With 5.118 inches of cutting capacity, the NISHIJIMAX NHC-130 saw can process a broader range of shafts, billet, tube, pipe, and forged blanks than the smaller NHC machines. It remains a dedicated high-speed circular saw, making it appropriate for repeat cutoff applications where part length, cut consistency, and throughput are more important than general-purpose sawing flexibility.
A servo-controlled sizing axis positions the material for each programmed cut while the cutting axis uses its own AC servo motor and ball screw. Separating those movements allows the Pat Mooney NHC-130 high speed production circular saw to control material position and blade feed as distinct parts of the automatic cycle.
Hydraulic clamping holds the workpiece as the blade moves through the section, while precision guides support the blade close to the cut. Powered tooth brushing and automatic lubrication help manage chips and friction over repeated cycles, supporting blade condition during longer production runs.

The Pat Mooney NHC-130 Series is a Nishijimax high-speed carbide circular saw that extends automatic cutoff production into 5-inch-class round bar. 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 0.590 to 5.118 inches (15 to 130 mm) for round stock and 0.590 to 3.54 inches (15 to 90 mm) for square stock. The machine uses a 21-hp (15-kW) saw motor, a 16.53-inch (420 mm) blade, a 35–120 rpm blade-speed range, and servo-driven cutting and sizing axes. 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 130 mm round limit covers part families that exceed the NHC-110 working range without moving to a 6-inch-class saw.
The 15-kW drive and 35–120 rpm range allow blade speed to be matched to stock size and material.
Six-point blade guidance near the workpiece controls the blade as it enters and exits the cut.
Servo indexing can be paired with engineered loading and exit equipment for recurring cut-to-length work.
The NHC-130 raises maximum round capacity from 4.33 to 5.118 inches and maximum square capacity from 2.91 to 3.54 inches. The choice should be based on the full stock mix, not only the largest part.
The specification sheet lists a 21-hp (15-kW) saw motor, a 16.53-inch (420 mm) blade, 0.106-inch (2.6 mm) blade thickness, and a 35–120 rpm speed range. Final blade tooth count and grade depend on the material and diameter.
The published system accommodates 12- to 24-foot bars, with engineered load-table options extending to 40 feet. Floor layout, bar straightness, bundle weight, and support alignment should be reviewed before the handling system is specified.
The machine combines servo-controlled saw-head feed, servo material indexing, hydraulic horizontal and vertical clamping, close blade guides, and automatic-cycle control. Those systems keep the cutting variables repeatable from piece to piece.
The NHC-160 covers round stock beyond 5.118 inches and square stock beyond 3.54 inches. Its larger structure and blade range also provide a different process match for production centered on heavier sections.
