Blanking Technology of CNC Bending and Forming

Fine Blanking: Fine blanking or fine-edge blanking method compresses the whole material sheet before blanking. It uses two punches, the top and another at the bottom for the compression of the sheet. The fine blanking method helps companies achieve tighter tolerances and minimizes the possibility of burr after cutting. This method produces smoother edges while reducing polishing costs.

Continuous Strip Blanking: As the name suggests, this technique uses the continuous addition of metal sheets into the press. This feeding of metal sheets for blanking is called continuous strip blanking and helps in the accurate reproduction of a large number of sheets. This method is pivotal in large-scale industrial productions of parts such as bottle caps, medals, and coins.

Compound Die Stamping: Another key method of metal sheet blanking is compound sheet die stamping. This technique helps in the production of most complex parts, especially using steel. In this method, engineers feed the metal to the fast-output compound stamping machine. It accurately stamps the metal for the production of steel parts at a large scale.

Progressive Die Stamping: This method is different from compound stamping as it uses sheet metals in coiled strips. The machine stamps, trims, and bends the coils of metal. This results in the formation of conjoined strips that separate into identical and individual components.
