A screw press is a type of machine press in which the ram is driven up and down by a screw. The screw shaft can be driven by a handle or a wheel. It works by using a coarse screw to convert the rotation of the handle or drive-wheel into a small downward movement of greater force. The overhead handle usually incorporates balls as flyweights. The weights helps to maintain the momentum and thrust of the tool to make it easier to operate.

The screw press was first invented and used by the Romans in the first century A.D. It was used primarily in wine and olive oil production. The screwpress was also used in Gutenberg's printing press in the mid-15th century.

A press is a metalworking machine tool used to shape or cut metal by deforming it with a die. It is frequently used to punch holes in sheet metal in one operation, rather than by cutting the hole or drilling.

If used as a punch, the tool itself consists of a punch and a matching die, into which it very closely fits. Both are usually precision machined and then hardened. The material is introduced between the punch and die, and the machine operated. The punch will cut through the material in one movement by shearing it. The punch and die may be of any desired shape, so odd shaped holes and cutouts may be created.

If used as a forging tool the dies can be many different shapes varying from flat to various shapes that will mold the metal to the desired configuration.screw press is a type of machine press in which the ram is driven up and down by a screw.
