Pat Mooney’s Nishijimax NHC-100ND cutoff system features an exclusive remnant reduction device to greatly reduce the amount of the remnant in auto cycle. When the amount of incoming bar is less than 90 mm plus cut length, the cutoff system automatically shifts the length setting device to a special NC-controlled gripper vise on the outfeed side of the saw blade. This device will grip the bar end from the outfeed side of the saw blade and continue until the final bar end is 30 mm. This process is automatic and adds 1 sec. to the final parts of the bar end. The NHC-100ND will continue to cycle as long as bars remain on the table or until a pre-determined number of cuts are made.
 
The Nishijimax NHC-100ND’s 15.5-hp induction motor drives the saw blade spindle via reduction gearbox. The rpm output of the gearbox is controlled by a FREQROL inverter drive.  This system is designed to offer precision torque control. Constant torque is maintained throughout the RPM range. This is especially important when sawing through materials at high sawing rates.
 
The NHC-100ND’s precise feed rate is set automatically, and input chip load is maintained through Nishijimax’s exclusive NC saw spindle feed axis. 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, and job setup takes less than 5 minutes with the CNC controller.
 

Other features of the NHC-100ND include Nishijimax’s original powder metal saw blade brake for zero vibration when the blade enters the cut. A gearbox oil chiller maintains constant gearbox temperature throughout 24/7 operation, thereby extending the life of the gearbox and the saw blades. NHC-100ND saw blade lubrication is supplied via air to the cutting edge of the blade with a precision-metered system. No flood coolant is used. The lubricant is used during the sawing of the material.
