What is sheet metal blanking and why the quality of equipment and personnel is important
Types of cut
The cut can also be straight or closed perimeter, depending on the final shape to be obtained.
The latter is what is obtained by means of a punch.
In this case the metal is pushed by the punch into a special compartment in the die, while the ejector takes care of “re-emerging” the piece once the hole has been drilled.
Blanking with cutting edges
In the case of sheet metal shearing using cutting edges, on the other hand, it is cracking that comes into play. In substance, the cut is produced when the crack of the fixed cutting edge and the crack of the movable cutting edge meet.
In this type of sheet metal blanking, it is very important, in addition to the use of the correct tools, also the skill of the operator, particularly in the game, namely in the space to be left between the sheet metal and the cutting elements.
Machinery and technical staff
If the right balance is not found, in fact, the cut will inevitably be inaccurate, with poor quality results.
This is why Tecnos uses only the latest generation of equipment at its headquarters in Cuggiono. Even the technical staff undergoes continuous refresher courses in order to keep up to date with the latest technological innovations and offer the customer an ever better service.
Sheet metal blanking and shearing are fundamental steps in the realization of what will become the finished product.
