General information
The PM-1228VF-LB features a high-torque 2 HP brushless 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 lathe ships fully
assembled, net weight 490 lb. A sheet metal stand with two cabinets is available as an option.
The spindle has a 1-1/2 inch bore and is unusually short, ideal for through-spindle work. Long service life is assured
by high precision taper-roller spindle bearings, together with hardened and ground bed ways, shafts and headstock
gears. All internal gears in the machine are oil-bath lubricated.
A saddle-feed gearbox, together with a set of external change gears, provides for a full range of UNC and UNF
threads from 5 to 72 TPI, and metric threads from 0.5 to 4 mm pitch. The leadscrew is quickly reversible for left
hand threading.
The saddle-feed gearbox also drives an independent hex-section feed shaft to power the saddle and cross-slide in
both directions. Like the leadscrew, the saddle/cross-slide feed shaft can be quickly reversed. An adjustable dog
clutch on the feed shaft allows the saddle to be stopped precisely at any point along the bed. All internal gears in
the saddle-feed gearbox are continuously splash-lubricated.
