How to Choose Slitting Blade on Slitter and Rewinder Machine?

Slitting blade is mainly used for cutting paper,plastic film,silver foil,aluminum foil,copper foil,tape,etc.Min. blade cut resistance and max. abrasion resistance are required.Because of requirement on production precision,cutting edge will be required to have micron-level precision,material will be 9CrSi,Cr12mov, w6mo5cr4v2,w18cr4v,etc. In the manufacturing process,precision of slitting blade tool holderes determines precision of product incision.That's to say,it is the most effective tool to determine product quality.
