This article discusses the presses, auxiliary equipment, and dies used in the blanking and piercing of commonly used magnetically soft materials, namely, low-carbon electrical steels and oriented and nonoriented silicon electrical steels. It describes the effect of stock thickness and work metal composition and condition on blanking and piercing.

Is There a Difference Between Blanking & Punching?

Blanking and piercing are shearing processes in which a punch and die are used to produce parts from coil or sheet stock. Blanking produces the outside features of the component, while piercing produces internal holes or shapes. The web is created after multiple components have been produced and is considered scrap material. The "slugs" produced by piercing internal features are also considered scrap. The terms "piercing" and "punching" can be used interchangeably.

Our robust, quality-driven stamping capabilities include:. Both blanking and punching are material forming processes that involve the precise removal of material from a workpiece. The main difference between the two processes lies in the end product produced. On the other hand, in punching operations, the material removed is discarded, and the final product is the remaining material which then undergoes further processing. Another difference between the two processes is how manufacturers approach processing the initial sheet material. In a punching operation, they typically remove the smallest amount of material necessary from the original workpiece to minimize material waste. In contrast, blanking operations are most efficient when the maximum amount of material is removed from the workpiece.

In order to improve the life of final-forming and sizing rolls, the areas of these rolls, Elliptical vibration cutting, which has been proposed by the authors, is applied to ultraprecision diamond cutting of hardened steel in the present research. Also the energy required ED for dynamic blanking was greater than that for the corresponding quasi-static process ES for all three materials at all the temperatures investigated. Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fibre and some forms of plastic sheet. Blanking and punching are the most commonly used severing process in sheet metal forming, often combined with other forming operations as an intermediate or finishing production step.

We apologize for the inconvenience...

Piercing, punching and blanking are three common machining processes that are used to manipulate raw metal, such as sheet metal. All three processes require the use of a machine, which in some way deforms or alters the physical properties of the raw metal. While similar, though, piercing, punching and blanking have different functions. 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. As the raw metal is pierced, the metal from the newly created hole is considered scrap.

Types of blanking dies There are two general types of blanking dies: the drop through dies and the inverted dies. Drop through dies: In this die, the die block assembly is mounted on the bolster plate or the press bed and the punch assembly on the press slide. The blank drops of its own weight through the die opening and the clearance provided in the bolster plate and press bed. This design is economical to build and maintain and is fast in working.

Compound die generally consist of blanking and piercing operation which are performed in single press stroke. This design tool is manufactured.
