The Gripflow Process uses a conventional, single-action hydraulic press with CNC controls, which allows the ram speed to be controllable in the cutting area.  A stamping is blanked from the parent material accomplished by minimal clearance between the punch and die components. The material retention during stamping ensures high-repeatability from part to part and dimensional accuracy to specifications. The scrap material is allowed to flow laterally. Hence, the name “Gripflow.” Slugs from pierced holes are allowed to pass thru the compound punch eliminating the need to separate scrap from parts as is typically done in a Fineblanking operation.

The Fineblanking Process requires a special triple-action press and a “V” ring in the die to restrict the material from moving away from the shear zone during the blanking operation (opposite of Gripflow). This V-ring requires extra stock material and press tonnage (maximum of 40% of total blanking tonnage). Accuracies in most cases are similar to, or equal to, those of Gripflow.
