The Saw Company carries the Nishijimax CNC carbide cutoff system. Originally developed in 1990 to improve the uptime of Japanese automotive suppliers, it is designed for fully automatic cycles and is equipped with autoloaders and bar stockers. After a bar length has reached the remnant end, the loading table introduces a new bar on the infeed conveyor. The gripper vise locates the bar and feeds it into trim cut position. During this cycle, the unit discharges the remnant end into a scrap bin, makes a trim cut, and discards the trim cut end also into a scrap bin. The machine then feeds the proper cut length and continues production. The machine continues to cycle as long as bars remain on the table or until it has made a predetermined number of cuts. The NC saw spindle feed axis automatically sets a precise feed rate and maintains the input chip load. An AC servomotor with encoder controls the saw blade feed rate.
