how big a deal is abrasive embedding for paste abraisve processes?
(1/1)
coppercone2:
I got a assortment of various things related to abrasive pastes and I need compounds to use with them.
First I was going to go with diamonds but I started reading that people have alot of trouble with embedding. I thought I read or saw something that said that ultrasonic cleaning can take care of it, but I am not sure how thoroughly. I was worried that it might get stuck with the lowest grit compound.
Silicon carbide.. I don't know if it embeds or not. At least it might get blunted fast enough that its easy to clear?
And then I found timesavers compounds, which claim to not embed, but I guess they are highly friable, and might cut slow.
I also read that some people can scrape some tools with a razor blade and stuff like that, but it seems dubious.
Is avoiding diamond actually a good idea to help keep your tool options up?
Analog Kid:
So what material are you abrading?
If it's steel, not much problem with abrasive embedding.
Plastic, on the other hand ...
Stringwinder:
This is some of the grinding/polishing stuff I use.
Diamond 10" sharpening stones 150, 400 grit and whetstones 1500, 3000 grit.
For kitchen knives, wood cutting tools, scalpel blades and flat metal surfaces.
Literally razor sharp when correctly done.
Round grinding/polishing diamond discs 150 mm, 180, 600, 1500 grit.
Lathe tools, steel and carbide.
Cerium oxide on felt discs for polishing glass (like windshields).
3M Perfect-It III from coarse to ultrafine for paint, plexi and softer materials.
Rotating soft discs of various hardness or on thin cloth on a metal base.
"Embedding" is not something that is connected with any of these methods.
Rather the contrary if you use diamond powder pressed into a tin disc for polishing
materials much harder than the tin base.

I meant like for traditional serrated iron laps etc
I read some people will go as far as to re-grind the surfaces when they want to go to a lower abrasive size. Is it really that bad?
If you want interesting, copper tape + diamond powder + granite plate
I have alot of 'pre loaded' diamond tools, but this is for bare ones that use a oil paste
