Progressive Die Block

Progressive Die Block determines strip feed accuracy and die-to-die registration across stations. Any tolerance stack-up can propagate alignment errors, affecting part features. Precision CNC machining using 5-axis interpolation and thermal compensation achieves ±0.003 mm positional tolerances. The Progressive Die Block maintains critical datum consistency across forming, piercing, and trimming operations, minimizing die timing errors at high feed speeds. 

Progressive Die Block surfaces in contact with galvanized or aluminized substrates face adhesion-related galling. Micro-welding due to poor tribological performance compromises surface finish and increases cleaning cycles. Fine-grain tool steels with duplex nitriding and DLC coatings lower the coefficient of friction. This design allows the Progressive Die Block to operate at full press capacity without adhesive buildup or transfer marks.
