Piercing Process In Sheet Metal

In other words piercing operation produces an extruded hole in sheet metal.

Piercing process in sheet metal. Piercing is a shearing process where a punch and die are used to create a hole in sheet metal or a plate. Piercing is the operation of punching holes in the sheet metal. The metal from the freshly formed hole is regarded scrap as the raw metal is penetrated. The web is created after multiple components have been produced and is considered scrap material.

It is one of the most extensively used processes throughout die and sheet metal work. Piercing is a shearing method in which raw metal with a machining instrument is penetrated leading in a circular or other shaped hole being created. Difference between blanking and piercing. The process and machinery are usually the same as that used in blanking except that the piece being punched out is scrap in the piercing process.

As explained in the above image. Piercing does not break through the metal s surface like a drilling operation. As a result of applied force from the piercing tool sheet metal starts tearing and produces extruded hole slot. The piercing machine pushes through the sheet metal a device known as a blanking punch.

Blanking produces the outside features of the component while piercing produces internal holes or shapes. In blanking the piece is cut off from the sheet and it becomes a finished part. Sheet metal powder processes metal piercing piercing is a metal forging technique that is often performed as an auxiliary process in conjunction with other forging processes in the manufacture of a part. The slugs produced by piercing internal features are also considered scrap.

As the raw metal is pierced the metal from the newly created hole is considered scrap. Piercing operation produces an extruded hole or slot. The terms piercing and punching can be used interchangeably. It can be used to create a cavity or hole in the work piece.

Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Both blanking and piercing are shearing operations. Piercing is a shearing process in which raw metal is pierced with a machining tool resulting in the creation of a circular or other shaped hole.
