General information
These are compact, full-featured lathes ideal for the smaller model shop. The two models are identical except for bed length
and weight. They feature a high-torque 1 HP DC motor giving smoothly variable spindle speeds in two ranges, from 50 to 1000
rpm and 100 to 2000 rpm. Power requirement is 110 V, 60Hz. The lathes ship fully assembled, approximate net weight 395 lb
PM-1030V, 365 lb PM-1022V. A sheet metal stand with two cabinets is available as an option.
The spindle has a 1 inch bore, and is unusually short — just 11 inches, ideal for through-spindle work. Long service life is assured
by high precision taper-roller spindle bearings, together with hardened and ground bed ways. All internal gears in the gearbox
and apron are continuously splash-lubricated.
Power feed for the saddle and cross-slide is supplied by a three-speed gearbox driving a "two-in-one" leadscrew. This is a con-
ventional 8 TPI leadscrew for thread cutting, with a key slot to drive the saddle and cross-slide for routine turning and facing oper-
ations (an advantage of this arrangement, compared with using a leadscrew for all power-feed functions, is reduced wear on the
thread). External change gears provide for a full range of UNC and UNF threads from 8 to 80 TPI, and metric threads from 0.35
to 3 mm pitch. The gearbox is instantly reversible for left-hand thread cutting, and for reverse motion of saddle and cross-slide.
