Hey team.
My die making, lapping and polishing is really starting to pick up and I’m really starting to make some nice parts. Lapping bores with 3 micron paste is annoying though… haha.
So I did have a question to refine my process… the dies we use are 4140 or O1 - I normally harden them, then temper them in an oven then final polish to remove scale etc. I’m wondering if there’s any reason they can’t just be left glass hard?untempered? They aren’t under any impact and I’m curious if the surface will be a better finish due to its crystalline structure.
So yeah, is the full hard untempered die going to provide a better surface finish? It would also save me heaps of time not having to polish out the scale twice. The forces we use we won’t blow them
Up in out presses.
