Yoder Four-Post Cut-Off Mechanical Presses employ a fabricated steel sub-base, with screw-type lateral and vertical adjustment for machine alignment. The heavy, cast semi-steel frame is stress relieved and accurately machined to insure correct and permanent alignment of moving parts. The heavy duty, machined upper crosshead insures accurate alignment of the die rails, which are hardened and ground, and mounted in pilot grooves.
The crankshaft — a heat treated and machined alloy steel forging — and the flywheel are mounted in grease-lubricated, anti-friction roller bearings with dust seals. The air-operated, multiple-disc clutch and spring set brake are electrically controlled. Provision is made on the P-42 and P-52 presses for non-repeat, single stroke operation, manual cutting, and jogging.
These machines are furnished with a solid-type head, adjustable with spacers or, as an optional feature, can be equipped for setting of shut height with a single screw.
