Same here. I rarely need better than +/- 3 microns myself. And that's only for an occasional custom made tactical claw hammer.I don't think I need that level of accuracy.
Hey, if you are able to pawn off products that are 3 microns off target dimension you are selling claw hammers to the wrong market. Try that sloppy work with a toilet seat for an Air Force contract and you'll end up in the crapper.I rarely need better than +/- 3 microns myself. And that's only for an occasional custom made tactical claw hammer.
