Fine blanking, blanking, and stamping cut and shape steel, aluminum, and copper sheets using precision punches and dies. Fine blanking delivers clean, burr‑free edges for gears and mechanisms, while stamping supports high‑volume production of structural metal parts.
Fine blanking, blanking, and stamping are sheet‑metal forming processes used to cut and shape components with high dimensional accuracy. Blanking and stamping use a punch and die set in a mechanical or hydraulic press to shear material—typically steel, stainless steel, aluminum, or copper alloys. Fine blanking differs by applying a triple‑action press with controlled clearance, a v‑ring, and counterpressure, enabling clean, straight‑edged cuts with minimal burrs and precise tolerances. Tooling is mainly made of hardened advanced Cold Work Tool Steels and HSS. Dies, guide plates, stripper systems, and wear‑resistant inserts are designed for cyclic loads and abrasive contact. Tooling material selection considers thickness, ductility, and work‑hardening behavior to ensure proper edge quality. Applications include gears, clutch components, levers, brackets, seat mechanisms, electrical connectors, and structural sheet-metal parts. Fine blanking is preferred where smooth edges and high accuracy are essential, while standard stamping suits large‑volume, cost‑efficient production of formed and cut metal parts.
