Section 2 FEATURES & SPECIFICATIONS
MODEL PM-1440GS Lathe
General information
This is a gap-bed lathe with 2-axis DRO designed for day-in, day-out use in the larger model shop. Distance be-
tween centers is 40in., swing over the bed 14 in. With an all-up weight of 1800 lb, plus 8 spindle speeds from 60
to 1800 rpm, the PM-1440GS is a robust heavy-duty machine. The spindle nose is D1-5 Camlock. A quick-change
carriage feed gearbox provides a full range of leadscrew ratios for U.S. and metric screw cutting, together with an
independent power feed for both saddle and cross slide. The power feed shaft is driven through a friction clutch
that allows the saddle to be stopped precisely at any point along the bed.
The 2-inch bore spindle comes with a stock-centering spider and MT6 internal taper. It runs on high-precision
NSK tapered-roller bearings, and is driven by a 3 HP (2200 W) 220 Vac single-phase motor. A treadle-operated
drum brake stops the spindle instantly, even at the highest speeds. A circulating coolant system is installed in the
right hand stand cabinet.
