Microns vs. grit size

MeDoctor · Aug 5, 2006

Can anyone point me to a good conversion chart. I'm getting ready to order some PSA lapping film for my EdgePro. I want to cover a range from about 300 grit to 4000. I've got blanks set up right now with 400/600/800/1000/1500/2000 wet or dry applied with spray adhesive. It works great, but changing paper is a pain, plus the wet or dry tears too easily.

Thanks,
Mark

I'm not sure what you are looking for, but here's a start.

Thanks. That one's a bit more complete. Looks like I need to start at about 30 microns.

Not a chart but a link to fine grit sandpaper(up to 8000 grit) the grit and comparitive micron size are given next to the sandpaper.

Just placed an order with R.S Hughes and discovered afterward that they have a storefront/warehouse less than 15 miles from me. I got A/O PSA film in 30, 12, 9, 3 ,and .3 microns, plus diamond film in 3, 1, and .5 microns.
