Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.
A forming press, commonly shortened to press, is a machine tool that changes the shape of a work-piece by the application of pressure. [1] The operator of a forming press is known as a press-tool setter, often shortened to tool-setter. Presses can be classified according to their mechanism: hydraulic, mechanical, pneumatic;
The hydraulic press depends on Pascal's principle.The pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force.
The working principle of a hydraulic jack. In 1838 William Joseph Curtis filed a British patent for a hydraulic jack. [4] In 1851, inventor Richard Dudgeon was granted a patent for a "portable hydraulic press" – the hydraulic jack, a jack which proved to be vastly superior to the screw jacks in use at the time. [5]
A 4-ton ratcheting arbor press. An arbor press is a small hand-operated press. It is typically used to perform smaller jobs, such as staking, riveting, installing, configuring and removing bearings and other press fit work. Punches, inserters, or other tools/dies may be added to the end of the ram depending on the desired task.

Press fit is achieved with presses that can press the parts together with very large amounts of force. The presses are generally hydraulic, although small hand-operated presses (such as arbor presses) may operate by means of the mechanical advantage supplied by a jackscrew or by a gear reduction driving a rack and pinion. The amount of force ...
A hand scraper is a single-edged tool used to scrape metal or other materials from a surface. This may be required where a surface needs to be trued , corrected for fit to a mating part, retain oil (usually on a freshly ground surface), or be given a decorative finish.
