Fine Blanking Sheet Metal

It ranges from 0 0003.

Fine blanking sheet metal. Which blanking process sheared the sheet metal in three type of force separately applied. The tooling of fine blanking clearance will affect the final stamped part burrs height. Fine blanking permits 3 d composite processing including coining semi shearing bending and drawing. Sheet thickness varies from 0 1 mm up to 12 mm and width up to 350 mm.

The fine blanking provides parts having smooth edge better flatness and high tolerance. 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. The working principle fine blanking of a typical spur gear is presented in fig. 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.

Fine blanking ensure stability regarding production with high quality and precision. Fine blanking is a fully automated precision metal working stamping process. Sheet metal blanking process fine blanking process. It is also similar to stamping but differs in the sense that it uses two opposing dies to form the gear from sheet material.

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. The fineblanking technology enables manufacturing of precision components without any finishing operation of the blanking cutting surface since the sheet metal is held still with an additional press force. Fine blanking process is one the specialize type of process. 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.

Fine blanking is similar to extrusion where the metal is extruded through die cavities to form the desired gear tooth geometry. Image courtesy of dayton progress. Fine blanking presses are similar to other metal stamping presses but they have a few critical additional parts.
