Hello again,
I was experimenting using some of the advice I got about tool post orientation and tooling and the piece of scrap I picked to play with was basic 6061 aluminum. After some turning, material was building up on the edge of the HSS tool bit. Not chips but stuck on stuff. I was able to fleck most of it off but some remained, like a little moustache along the edge. So, I used another tool, also HSS, but the cutting edge needed a little touch up. After touch up and use, again there was this little moustache along the edge. and the tool was clearly dull, again.
This got me wondering about HSS and if there are different grades - which, thanks to the internet, I discovered there are.
Now, what crap do I have that doesn't hold an edge and allows this moustache to form so, I started to think...
- Is there a way to determine what grade of HSS I have, which I obtained from LMS?
- What grade should I be using for home shop work and where can I get?
I'm not doing production work or nor do I have a contract with NASA, just home projects but I have determined that this moustache is giving me a lousy finish. And if it's lousy on aluminum, I dare not think about CRS or anything else.
