USI ZC 1980 Lathe

This is a fully geared headstock, gap-bed lathe with precise, hardened and ground gears, each gear thoroughly tested for accurate tooth configuration and flank engagement to insure optimum quietness and smoothness.  The drive and brake are achieved through mechanical "multi-disc" clutch system.  The precision ground spindle is supported by three tapered double roller bearings and features D-Cam lock mounting.  The gearbox is totally enclosed and is designed so a preponderance of standard and metric threads and feeds are attainable without gear change.  The carriage has extended range, with T-Slots for accommodating special tooling.  Nuts for elimination of backlash are externally adjustable, heavy duty taper attachment generates tapers of +/- 15 degrees up to 22 inches.  The apron has overload protection.  Bed way is of high grade, alloy cast iron, aged and normalized for maximum stability, with chrome bearing ways.  Heavy cross ribbing of the bed frame produces extra rigidity and dampens vibration.  Other features include dual spindle control levers, two-speed tailstock, micro-cutout chuck guard, four way rapid travel, safety interlock, forced lubricated head-stock, all which shows that this lathe comes with a formidable list of desirable features and standard accessories.
