Quench press
 A universal quench press is used for the precision quenching of gears, bearing rings, saw blades, slitting knives, cylindrical parts, flat parts, dished parts, and other articles. A set of quenching dies reduce or eliminate the distortions in size, roundness, taper, and flatness encountered in manufacturing processes prior to the press quenching process and/or operation. The press has a plurality of posts or tie-rods configured to distribute the forces of the applied loads uniformly. Provisions are made for a plurality of generally concentric rams with all of the rams powered by hydraulic or pnuematic cylinders or other force exerting device or devices to provide a uniform and evenly distributed force. An automatic quench media splash guard seals the quenching chamber during operation and requires absolutely no set-up or operating adjustments or changes. Two or more automatic doors provide complete access to the die area during set-up and/or allow two or more points for loading and/or unloading of workpieces and/or tooling. For ultimate accuracy, the lower die plate is stationary and provides a means of guiding the center ram, thus assuring concentricity. Graduated shims are added or removed from the center ram stop to decrease or increase the final part bore diameter as required.
