A single Nishijimax CNC Carbide Cutoff System can replace three to four production saws. Available exclusively from Pat Mooney Inc. – The Saw Company, these systems cut more parts per hour and more parts per blade than a standard production saw.

Designed for fully automatic cycles, all Nishijimax saws feature 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, and 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 Nishijimax’s exclusive 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, a Mitsubishi programmable servodrive and a precision ballscrew. Compared with hydraulic systems, there is no fluctuation for temperature or condition of the oil. According to the company, job setup takes less than 5 minutes with the CNC controller.

Other features include the 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 the saw blades, and an easily accessible oil pressure adjustment valve. Magnetic and drag-style automatic chip conveyors are offered as options.

Nishijimax blade capacities range from 2.75” to 9.00”.
