MODEL PM-727M and PM-727V MILLING MACHINES
General information
These are robust “square column” mills designed for use in the model shop. With an all-up weight of almost 600 lbs (includ-
ing the optional stand), they can handle far more than the typical small machine. For precise control of cutter depth there is a
worm-driven quill downfeed with graduated dial and DRO, completely independent of headstock up/down position.
The main dierence between M and V models is the motor — single speed ac (induction type) for PM-727M, variable speed
(brushless dc) for the PM-727V. The V model oers a signicantly wider speed range than the M model, 40-3000 rpm vs. 115-
1700 rpm.
The reversible spindle runs in high-quality tapered-roller bearings enclosed in a 2-1/2” diameter quill with coarse and ne
downfeed options. In the PM-727M an oil-lled gearbox provides 6 spindle speeds from 115 to 1700 rpm. The same gearbox
in the PM-727V provides 6 speed ranges from 40-190 to 1800-3000 rpm. Ground dovetailed ways for table and headstock en-
sure smooth, precise motion in all three axes (X = table left/right, 15 in. Y = table front/back, 8-1/2 in. Z = headstock up/down,
16 in.). The headstock can be tilted 90 degrees clockwise and counter-clockwise from the vertical.
