The NISHIJIMAX NHC-180/200 is a high-speed circular saw engineered for production cutting of larger steel bar, tube, and pipe. Depending on the configuration, the machine combines 21 or 26 HP saw power with capacity for seven- and eight-inch-class material. Servo-controlled cutting and a 19.68-inch material index automate stock positioning and the cutoff cycle, providing a productive solution for manufacturers and steel service centers processing larger ferrous cross sections.
NHC-180/200 Series (7 inch Cutting Capacity) Features:
The Pat Mooney NHC-180/200 Series (7 inch Cutting Capacity) platform covers round stock in the seven- to eight-inch class, depending on configuration, with square capacity reaching 7 inches. This makes the saws suitable for larger shafts, bar, tube, and pipe where shops want the speed and cut characteristics of a circular saw instead of relying exclusively on heavy bandsaw capacity.
Available 21 and 26 HP saw-motor configurations work with a published blade-speed range of 28 to 90 RPM. The 45° cutting axis uses AC-servo and ball-screw feed, giving the NISHIJIMAX NHC-180/200 saw controlled blade movement through larger cross sections rather than relying on an uncontrolled gravity or hydraulic-only downfeed.
The sizing system on the NHC-180/200 high speed production circular saw provides a 19.68-inch single index, with longer finished lengths produced through repeated material movement. Hydraulic horizontal and vertical clamping at the jig and sizer keeps the stock controlled during positioning and cutting, supporting repeat production from long bar.

The Pat Mooney NHC-180/200 Series is a large-capacity Nishijimax high-speed carbide circular saw platform for automatic production cutting of heavy bar, pipe, and structural stock. Its configuration places the machine within a defined range of cutoff work rather than treating it as a general-purpose saw.
The NHC-180 specification lists round capacity from 2 to 7 inches (50 to 180 mm), a 45-degree slant cutting axis, AC-servo and ball-screw saw-head feed, and a 21-hp (15-kW) saw motor. The NHC-180/200 platform weighs approximately 15,432 pounds and can be configured with bundle holders and engineered loading and exit systems. 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 NHC-180 configuration extends the NHC platform to round stock up to 7 inches for larger cutoff requirements.
Horizontal and vertical clamping on both sides of the blade supports the workpiece at the cutting zone.
Servo saw-head feed, spindle reduction, close guides, and chip brushing work together to control tooth loading and remove chips.
Optional bundle holders, load tables, conveyors, and part-diverter systems can be arranged around heavy incoming stock and finished pieces.
It identifies the large-capacity NHC platform offered in 180 mm and 200 mm configurations. The published NHC-180 specification covers round stock from 2 to 7 inches (50 to 180 mm), while the selected configuration depends on the required stock envelope.
It is evaluated for recurring production cutoffs in heavy solid bar, pipe, structural stock, and forging blanks where a 7-inch-class carbide circular saw can replace slower or multiple-saw processing. Material testing remains important for difficult sections and alloys.
Pat Mooney Saws can provide bundle holders that contain the stock after steel straps are removed, along with custom load tables and chain-loading systems. The design must account for bundle weight, bar length, alignment, operator access, and safe separation.
The platform uses close blade guides, clamping on both sides of the blade, servo-controlled feed, a precision spindle and reduction gearbox, powered chip brushing, and lubrication at the cutting tip. Correct blade selection and stock alignment remain necessary.
