MODEL PM-30MV Milling Machine
General information
The PM-30MV is a robust “square column” mill with R8 spindle and continuously-variable spindle speed up to 3000
rpm. It is designed for day-in, day-out use in the model shop. With a weight of 530 lbs, excluding stand, it 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 reversible spindle runs in high-quality tapered-roller bearings enclosed in a heavyweight quill with coarse (“drill-
ing”) and fine (“milling”) downfeed options.. It is powered by a 2 HP (1.5 kW) brushless dc motor. Spindle speed
is continuously variable from 50 to 1500 rpm, low range, and 1400 to 3000 rpm, high range. This is a “gearless”
design with two-step pulleys on motor and spindle coupled by a long-life ribbed belt. The headstock can be tilted
90
o
clockwise or counter-clockwise from the vertical.
Precision ground dovetailed ways for table and headstock ensure smooth, precise motion in all three axes: X = left/
right motion of table, 23 in. Y = front/back motion of table, 7-5/8 in. Z = headstock up/down, 14-1/2 in. Note: Instal-
lation of a DRO with external scales may limit these numbers.
Special accessory supplied:
Spindle nose C-wrench
Working clearances – space requirements for full motion of the table
If installing the PM-30MV on a bench, check hole spac
-
ings on the base of the delivered machine. Don’t pre-drill!
