squeegee corners
« on: October 18, 2017, 02:36:16 PM »
Aside from the corner rounder tool from Firmor, what's the easiest way to do this to like 40 squeegees?

bench grinder or the squeegee sharpener we have(which I don't use to sharpen, only to round corners).  It's pretty much a bench grinder with a sandpaper wheel.

You could also use a stationary belt grinder:

Yes the bench grinder is the best option IMO. May be in the minority but most squeegee sharpeners are not worth the investment; unless you go all the way and get automated ones. We also use the BG to radius the corners of our stainless steel ink scrapers. Good $45.00 investment

Our squeegee sharpener should be called a squeegee murderer.  We never use it for that.  Only for rounding corners and as a grinder.

A grinder is a fantastic thing to keep around a shop anyway.

We have a big squeegee sharpener, leftover from when we were doing UV ink.

How would i use it for corner rounding?

Some use belts, others, wheels. Just turn it on and play with it just watch your fingers!

I've always just used a little cheapo orbital hand sander. Takes like 10 seconds per corner.

What is the rationale for rounding the corners? 

Something for autos over manuals?

Nah, I think there's at least two of us in that camp, anyone want a like new sharpener? 

Rounding corners is actually the only thing the sharpener has made sense for, you use the wheel to buzz them off.  The fimor cutter, not so much there, can't seem to cut cleanly.  Belt/bench grinder sounds pretty much ideal.  Maybe a bench grinder with stone on one side for rounding and buffer on the other for flood bar polishing. 

Wayne you got to do this for most auto printing and especially high speed printing which takes more pressure in my experience.  The blade corners just cut right through emulsion after so many impressions.  It's kind of a catch 22 since you want a super sharp edge on the blade to shear ink but the corners will form a sharp point.   We both round blade corners and top tape to ensure the corners are riding on durable tape and not emulsion/delicate mesh.

Pigments have different properties; most of which are unseen to the naked eye. Most blues are conical in shape and can be abrasive. Titanium in white and carbon in black can abrade as well. Yes, this mostly applies to auto printing and especially WB apps. The pressure points are when the squeegeegee initially contacts the stencil at the right and left ends and thats where the radius benefits.

I've got a 1 x 6 plank with some course sandpaper glued to it, I just rub the corners on it just enough to knock the sharp edge off.
