Fly Press

A hand-operated press in which a horizontal beam with heavy steel balls attached to the ends gives additional momentum to the descending member used to punch or compress material.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.
