clearance between power shear blades? 2

[procyeon]

Hi guys,
i am new to the site so please excuse me if my question seems slightly fundamental. After replacing a pair of shear blades (60"*3"*1") on a power guillotine i proceeded to set the clearance between cutting faces expecting one of my colleauges to know the figure as i am new to the plant and not familiar with guillotines. I was pretty dissapointed that nobody knew and subsequent searches on the net have yielded little of value. After finding this site and browsing through various threads it's blindingly obvious that there are a hell of a lot of pedigree engineers and technicians who subscribe to it, and i'm sure someone will have the answer. Intuition tells me it will be material thickness dependant as with dies and punches. The material thickness varies from .030" -.050" and is mild steel in sheet form 48" in width.
Many thanks in advance,
J.P.RILEY.

Usual guideline is 5 - 10% of material thickness for mild steel. You trade off burr size for blade life.

Good Luck
