Minster Series P2 Automatic Production Presses
Standard Features
Frames: High tensile alloy cast iron frames of
four piece tie rod construction are mounted
on separate legs. P2-300 legs integral with
bed.
Openings in legs for conveyors or chutes on
outgoing side only. (Not available on P2-300.)
Drip trough around bed cast inteeral with

Crankshaft: Forged SAE 8645 alloy-steel full
eccentric two point shaft, machined, ground
and roll burnished.
Bearings: All wear points .. . main bearings,
eccentrics, lower connections and ways are
nickel bronze lined and easily replaceable.
Slide: Barrel type slide adjustment having easy
manual operation. Lower connection bush
ings are removable bronze plugs inserted in
connection screws.
Slide is of full box type construction with 8
extremely long ways widely spaced on ex
Speed of press operation is not unlimited.
The following factors control the speed
at which a press may be satisfactorily
operated:
1. Length of stroke for two reasons. First,
the longer the stroke, the greater the off-bal
ance centrifugal force due to the weight of
connection and bearing eccentric. The second
is the effect of moving the weight of slide
