FINE BLANKING


What us "FINE BLANKING"?

FINE BLANKING is a new technology of press manufacturing that uses high-pressure principle in hydrostatic pressure
that line up the metal texture and receive clean profile without creating breakdown.


Feature of FINE BLANKING

- Can gain 100% clean profile
- Can obtain precise measure and location
- Obtains minmum number of die roll
- Plane limit increases
- No change in measurement caused by regrinding since it obtains minimun number of clearance
- No use for machinery manufacturing such as Milling, Drilling, Reaming after the press manufacturing process
- Can perform forming manufacturing processes such ah Bending, Offset, Coining, and Extrusion.
- Decrease in prime cost as many manufacturing processes diminishes
- Can omit heat treatment process as profile hardness increases.


FINE BLANKING operation principle


The raw material insert to F/B 

FINE BLANKING method is new press technology,
which flows metallic structure by high-pressure theory
under static water pressure and get the clean front cut end
and doesn’t cause any vibration or wave cut end.
 
- The operates pressing to 20~40% for material fixed to the mold(Guide plate , Die plate)
- The counter pressing 10~20% for prevent reverse bending during main punch process(Counter punch)
- The main power punches (50-80) is activated than F / B Press Finishing Process.
