Fine Blanking Sheet Metal

Fine blanking permits 3 d composite processing including coining semi shearing bending and drawing.

Fine blanking sheet metal.

Fine blanking is a high precision type of blanking which is the die cutting of the outside shape of a part. Fine blanking is a fully automated precision metal working stamping process. Which blanking process sheared the sheet metal in three type of force separately applied. A typical compound fine blanking press includes a hardened die punch male the hardened blanking die female and a guide plate of similar shape size to the blanking die.

It ranges from 0 0003. Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry. Hope the following picture of a stamping factory experience will help you understand what is fine blanking and what difference between fine blanking and common punching and blanking process for sheet metal parts. Fine blanking ensure stability regarding production with high quality and precision.

The tooling of fine blanking clearance will affect the final stamped part burrs height. Prominent leading manufacturer from pune we offer sheet metal component fine blanking sheet metal press parts automotive sheet metal components sheet metal press tool and compressor switch body. Sheet metal blanking process fine blanking process. The working principle fine blanking of a typical spur gear is presented in fig.

Fineblanking is a specialty type of metal stamping that can achieve part characteristics such as flatness and a full sheared edge to a degree that is nearly impossible using a conventional. Fine blanking process is one the specialize type of process. The fine blanking provides parts having smooth edge better flatness and high tolerance. Fine blanking uses a specialized metal stamping press that provides equal pressure from both top and bottom on the metal sheet to produce flat edges by cutting the periphery in one stroke.

It is also similar to stamping but differs in the sense that it uses two opposing dies to form the gear from sheet material. Figure 1 when a punch makes contact with the sheet the metal begins to deform and bulge around the point of the punch. Fine blanking presses are similar to other metal stamping presses but they have a few critical additional parts.
