flywheel mounted on the screw.
• It operates on the principle of leverage, with the operator manually rotating the handle to move the screw and
apply force to the workpiece.
• The flywheel provides additional momentum, allowing for more efficient force application and reducing the effort
required by the operator.

Applications:
• Metalworking: Fly presses are commonly used for tasks such as punching, bending, embossing, coining, and
riveting in metalworking shops and small-scale manufacturing operations.

• Jewellery Making: They are utilized in jewellery workshops for tasks such as blanking, forming, and stamping
precious metals and alloys.
