PRECISION MATTHEWS PM-1340GT MANUAL LATHE

Technical Description

The Precision Matthews PM-1340GT is a 13"x40" ultra-precision geared head lathe manufactured in Taiwan, featuring a large 1-9/16" spindle bore with a clear-through design for through-headstock work. The machine accommodates a maximum swing of 13 inches over the bed and 6-1/2 inches over the cross slide, with a gap insert capacity of 7-3/4 inches extending the swing to 19-1/8 inches. Equipped with a 2 HP motor and 12-step spindle speeds ranging from 90 to 1,600 RPM, the lathe delivers variable feed rates from .002 to .02 inches per revolution longitudinally and .001 to .01 inches per revolution cross-feed for precision work. The machine supports both inch and metric threading capabilities, cutting 4-112 threads per inch (40 different threads) and metric pitches from .25-7.5mm (24 different threads). Built with induction-hardened and precision-ground bed ways, the lathe resists wear while maintaining excellent surface finishes in all directions. The 7/8" diameter lead screw features an 8 TPI pitch, while the spindle incorporates precision tapered roller bearings for ultimate spindle accuracy and longevity. The machine mounts via D1-4 cam lock with an MT #5 internal spindle taper and includes a short spindle length through the headstock of 13-3/4 inches. Power requirements are 208-240 VAC, 60 Hz, single or three-phase operation with a recommended 20A circuit. The PM-1340GT comes standard with a 5-year warranty and requires direct wire connection to the cabinet rear.
