Sheet metal working machinery is a category of machine tools that are specifically designed to shape, cut, and form sheet metal into specific parts and components. It is used in a wide range of industries such as automotive, aerospace, construction, and HVAC (Heating, Ventilation, and Air conditioning) to produce various parts such as automotive body parts, aircraft parts, HVAC ducts, and other sheet metal products.

Some examples of common sheet metal working machinery include:

• Shearing machines: used to cut sheet metal into specific sizes and shapes by applying a linear force to the workpiece.
• Bending machines: used to bend sheet metal into specific angles and shapes.
• Punching machines: used to punch holes and other shapes into sheet metal using a punch and die.
• Rolling machines: used to roll sheet metal into specific shapes such as cylinders or cones.
• Stamping machines: used to stamp or emboss specific patterns and designs into sheet metal.
• Laser cutting machines: used to cut sheet metal using a laser beam.
• Waterjet cutting machines: use high-pressure water to cut sheet metal.

Sheet metal working machinery can be powered by a variety of different sources, such as electricity, compressed air, or hydraulic power. They can be operated manually, semi-automatically, or fully automatically depending on the type of machine and application.

The sheet metal industry relies heavily on automation and the use of advanced computer-controlled machines to ensure precision and efficiency. Many sheet metal working machines are now CNC (computer numerical control) operated, which allows for precise and repeatable cutting, punching and bending operations. These machines require skilled operators and proper maintenance for optimal performance and production of accurate and precise parts.
