Here are some questions about sand etching grit and vinyl cutter equipment asked by fellow customer, Nick.
“Hey Eric, so I’ve been using a 150 grit and it’s coming out nice but
not a smooth as I like, do i need a finer grit or courser? The higher
the number the finer the grit right? The finer the grit the smoother
the etch? for a smooth smooth etch what grit would you recommended.
Also, how long do the blades on the us cutter machine last? Is it okay
to cut like 40 stencils at a time or will that over work the machine?
Thank you soooo much for your support!! You’re the best can’t wait to
show you what I’ve been working on, blessings , nick.”
Hey Nick, great to hear from you. Yes the finer (higher number) the grit the smoother. Many people chose different grits, but I personally use 180 grit. Some will use as low
as 100 grit and others use a grit so smooth that its considered powder. But the majority
of people use between 120 and 200 grit. Just remember the smaller the grit, usually
doesn’t last as long, that’s why I chose 180.
I can’t give you an exact number on the longevity of the blades. It depends on the
thickness of the vinyl and such. Cutting 40 stencils seems okay, but I don’t know how
big they are. Maybe try 2 sets of 20 at first.
That would be great to see what you’ve been etching. If your interested, I can feature
it on my blog with credit to you at the engraving and etching news area.
I hope that helps. Best of luck
-Eric
