A quench press is a machine that uses concentrated forces to hold an object as it is quenched. These type of quench facilities are used to quench large gears and other circular parts so that they remain circular. They are also used to quench saw blades and other flat or plate-shaped objects so that they remain flat.
Quench Presses are able to quench the part while it is being held because of the unique structure of the clamps holding the part. Clamps are slotted so that oil or water can flow through each slot and cool the part and the ribs of the clamps can hold the part in place.
Recently, high pressure gas quenching has become more popular for several reasons: it is more environmentally friendly, the flow of the gas is easier to control than the flow of oil in a quench press, and a single machine with low pressure carburizing and high-pressure gas quenching replaces the three machines of a carburizing furnace, an atmosphere furnace, and a quench press.
