Fineblanking, a cold forming process for high volume production of precision components, is a type of stamping operation that simultaneously compresses and shears sheet metal in order to reduce the amount of tearing along the edge. The fineblanking process produces blanks with edges that are entirely smooth. The benefits of fineblanking over other blanking operations include:
· Better flatness
· Reduced or eliminated finishing operations and machining costs
The fineblanking process incorporates three forces. Stinger Pressure is applied to the raw material surrounding the area to be fineblanked. An impingement is created in the material, which may be applied to one or both sides of the material, depending on material thickness. Main Pressure extrudes the part from the material strip. Counter Pressure opposes the Main Pressure to help maintain the shape, flatness and integrity of the component throughout the fineblanking process. After the part has been formed, the tool is opened and the part and slugs (offal) are ejected from the tool and exit through the back of the die. Fineblanking dies are robust tools featuring tight clearances between elements (generally 1/2 of 1% of material thickness). |  |
The fineblanking process is well suited for the manufacture of components in a wide variety of industries. Far from being a niche technology, the extent of the fineblanking process' versatility has yet to be fully realized.
