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

Intricately shaped holes
Slots and projections
Coining and thinning
Forming
Shallow chamfers
Semi-pierces
Pockets
Counter bores and countersinks
Bends and offsets

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.
