According to manufacturer Pat Mooney, a single Nishijimax CNC carbide cutoff system can replace three to four production saws. By integrating cutoff technology into a sawing machine, the system has achieved reductions in operations (cuts from 50 seconds to 7 seconds), high rpm with minimal kerf and swarf, and greater chip load.

The sawing systems are equipped with a auto loaders and barstockers. After a bar length has reached the remnant end, the loading table introduces a new bar on the in-feed conveyor. The gripper vise locates the bar and feeds it into trim cut position. During this cycle, the remnant end is discharged into a scrap bin, the trim cut is made and discarded into a scrap bin. The machine then feeds to proper cut length and continues production. The machine will continue to cycle as long as bars remain on the table or until a predetermined number of cuts are made.

With the company's NC saw spindle feed axis, a precise feed rate is set automatically and input chip load is maintained. The saw blade feed rate is controlled via an AC servomotor with encoder, servodrive and precision ball screw. Job setup takes less than 5 minutes with the CNC controller.

Other features include the sawing system's original powder metal saw blade brake for zero vibration when the blade enters the cut, a gearbox oil chiller to maintain constant gearbox temperature throughout 24/7 operation, thereby extending the life of the gearbox and saw blades and an easily accessible oil pressure adjustment valve.
