Mechanical punch copying machines, also known as punch copying mills or punch copying machines, are machine tools used to produce punching tools for metalworking. They enable the precise replication of complex shapes by scanning a template (a pattern or template) with a special cutting tool and transferring the shape of the tool onto a piece of metal. The operation of a stamp copying machine is based on the principle of scanning and replicating. The machine uses a tracing system to scan the contours of the pattern and pass this information to the cutting tool. The cutting tool then cuts out the metal according to the shape of the pattern. Stamp copying machines are widely used in sheet metal fabrication, especially in the production of stamping dies and molds. They can also be used in other industries such as automotive, aerospace and machine building. The machines are usually accurate, fast and effective and can produce complex shapes and patterns. There are different types of stamp copying machines, such as manually operated or CNC-controlled machines. The choice of the appropriate machine depends on various factors, such as the type of material, the complexity of the shape, the size of the parts, and the requirements for precision and production speed.
