Q. In metal forging process, the gravity drop hammers are operated by a ram using steam or pressurized air.

in the metal forming process, drop hammers are mainly of two types which are gravity drop hammer and power drop hammer. gravity drop hammers are the tools which achieve their energy by the falling weight of a heavy ram. the force mainly depends on the height of the drop and the weight of the ram. and power drop hammers are in which a ram is accelerated by the steam or pressurized air.
