Section 2 FEATURES & SPECIFICATIONS
MODEL PM-1236 Lathe
General information
The PM-1236 is a robust gap-bed lathe designed for day-in, day-out use in the model shop. Distance between
centers is 36 in., swing over the bed 12 in. With an all-up weight of 1000 lb, plus a wide range of speeds from 65
to 1810 rpm, the PM-1236 can handle far more than the typical small machine. The spindle nose is D1-4 Cam-
lock. A quick-change carriage feed gearbox provdes 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 spindle has a 1-1/2 in. clearance bore and MT5 internal taper. It runs in tapered-roller bearings, and is driven
by a 9-speed gearbox, coupled by Vee-belts to a 2 HP (1500 W) 220 Vac single-phase motor. Two-step pulleys
provide a choice of high and low speed drives, giving a total of 18 spindle speeds — 9 high range plus 9 low
range. A treadle-operated disc brake stops the spindle in milliseconds, even at the highest speeds. A circulating
coolant system (optional) may be installed in the right hand stand cabinet.
