Fine Blanking

With Fine blanking, components of very high accuracy are attainable - tolerances of plus or minus 0.015mm are achievable.

 

Holes with a diameter as small as 60% of the material thickness can be pierced.

Material up to 20mm thick can be fine blanked.

The edge quality and accuracy of the fine blank process can eliminate the need for secondary processes e.g. reaming of holes or shaving to get a square smooth edge.

Components remain very flat.

Components can have features such as countersinks, extrusions, semi-pierces, weld projections, coined chamfers, counter bores, and offsets applied to them in the pressing operation.

Tooling is generally of a compound nature (as opposed to progressive type). This ensures superior positional accuracy between features.

Tooling prices are competitive compared with conventional tooling.

Virtually any metal can be fine blanked (we commonly fine blank various steel grades, copper, aluminum & stainless steel).
