Processing technology "Fine Blanking"

A machining method that achieves machining accuracy through press processing.

Our company offers a processing technology called "Fine Blanking," which allows us to achieve the precision of products traditionally done through machining, using only press processing. This method involves reducing the clearance between the punch and die, while restraining the workpiece with a stripper (V-ring) and counter during the punching process. Products processed with this technology achieve a smooth shearing surface and excellent flatness, allowing for high precision in three-dimensional shapes such as counterboring, face mounting, and partial punching, thus eliminating the need for secondary processing. 【Features of the Output】 ■ Shearing Surface: Depending on the shape, we can guarantee over 80% shearing at specified locations. ■ Flatness: Although it is influenced by the size and shape of the product, it can be managed within 0.05~. ■ Punching Precision: It is affected by the size and shape of the product, but we can manage a tolerance range of 0.06~. *Please contact us for more details.
