Used Automatic Punching Machines for Sale — 211

What is an automatic punching machine?

An automatic punching machine is a machine tool, which is used to separate thin-walled materials. Automatic punching machines are closely related to punching press. As they were further developed, automatic punching machines no longer required human staff for operation, unlike the conventional punching press.

Where are automatic punching machines used?

A automatic punching machine is applied where a large amount of series components need to be produced in a very short space of time. They are most suited for processing wood panels, plastic panels, plastic films, rubber materials and sheet metal. In addition to reducing the need for permanent handling, automatic punching machines have a much higher output rate than manual punching press. This means that they are also very economic. Useful additions for automatic punching machines are industrial robots or reels. Cut-to-length lines are also often equipped with a punching machine.

What types of automatic punching machines are available

Generally, all punching presses can be transformed into automatic punching machines. Due to the automatic nature of these machines, a lot of safety features that are required for manual punching presses are no longer needed. Automatic punching machines are pneumatically operated in the packaging industry. An automatic punching machines is often integrated into the assembly lines for the production of cartons and film packaging. For metal processing, automatic punching machines are electro-mechanically operated. The most common types are knee lever punches, spindle-powered punches or punches with an eccentric drive. Hydraulically operated machines are less common. Hydraulic punches are only used for very tough or particularly thick material. The hydraulically operated punching process is much slower than the electromechanical or pneumatic punches. This means that they are very inefficient when run automatically.

There is a higher amount of pressure required for the separation of material, particularly sheet metal, than for forming processes. Automatic punching machines, including automatic paper punching machine, automatic die punching machine, automatic spiral punching machine and automatic hole punching machine, can also be used as an automatic press. Automatic punching machines can produce a large amount of processed material in a short amount of time. It is important to have continual quality control. The processes of an assembly line, where an automatic punching machine is integrated, all need to be very precisely coordinated with one another. Without continual monitoring of the production process and results, there is always the risk that a lot of waste will be produced.
