What to know about CNC punching?

CNC punching is a programmable metalworking process. It is one of the best and most effective techniques for sheet metal fabrication projects. CNC punching machines are pre-programmable and reliable pieces of equipment used for punching shapes into sheet material.

There is a rising demand for metal components across sectors such as automotive, aerospace, and construction. This has driven the global punching market to expand rapidly.

CNC Punching

CNC is short for Computer Numerically Controlled punching. It uses a punch and die and can complete tasks manually or automatically. It can cut, perforate, and shape metal sheeting, using a matrix similar to a punch.

The desired pattern is formulated in data, which is then used in the CAM stage of the cycle to determine the best tools and sheet material to use for the design.

CNC nesting is used to determine the best arrangement, in accordance with the sizing of the material sheet. Precise coordinates are used to determine the finished shape.

The machinery moves the sheet material into place and a punching ram creates the design.

Anything from stainless steel, aluminium, and brass can be used as sheet material.

The CNC program contains specific instructions for driving the machine to construct the specified geometry.


New technology means that high-quality CNC punching machines are capable of high productivity and performance with low maintenance costs. Manufacturers such as Euromac have developed machinery which is flexible for ease of fulfilment of all production requirements, whether small or large.
