Fine Blanking – The Leading Edge
Fine Blanking is a metal forming process used to produce ‘Net Shape’ finished parts in single operation or with minimal secondary processing. Hydraulic presses are used to actuate the tool and die in three motions, thus makes clear shear with straight edges with no fracture zones, good flatness tolerances and high level of angular accuracy. Comparing to conventional stamping process, the die clearance in Fine Blanking process is one tenth, which eliminates the tearing on the cut edges of the parts
Advantages of Fine Blanking Process
Types of geometry that Fine Blanking Process can produce
|FINE BLANKING||CONVENTIONAL BLANKING|
|100% Clean sheared edges||Edges are not 100% clean|
|Surface finish can be achived up to 0.8 microns||Not Possible|
|Better wear resistance at edges||Poor wear resistance at edges|
|Excellent flatness ie., no material deformation while blanking||Material deformation occurs|
|Small, pierced holes relative to material thickness can be achieved||Not possible|
|Reduces or Eliminates costly secondary operations||Not possible|
|Tight dimensional tolerances can be achieved||Not possible|
LGB is fully equipped to meet your demands for both Fine Blanking and creative forming so that you get the advantage of cost savings, reduced process time, fast operations and parts that are of outstanding flatness and dimensional accuracy. The Fine Blanking tool is a specially designed complete press tool with a V-ring and an extremely small punch-die clearance. LGB brings to bear its expertise in all areas of operation right from Raw Material, Tool engineering, Process design, to give customers the very best Fine Blanked Parts & Assemblies.
LGB’s array of Fine Blanking presses offer a wide range of tonnage from 100 tons to 1000 tons.
