Re: Marks on Work When Pulling Carriage/Cross Slide Back?

It's tool pressure. Reverse the feed and run the carriage out under power for a full clean-up with no marks.

Exactly the same method I use. Here I thought I was being all clever. :lol:

Re: Tantung parting tool question.

You were right Russ. At top speed I was starting to get some erosion at the end of the tool. I've backed it off to my original 1000rpm and will see how well it holds up. Even at the reduced speed it is worlds beyond the performance of my old Red Cut Cobalt tools.

Re: Tantung parting tool question.

So far I have made just over 100 cuts in 9/16" material and honed the cutting edge once. It didn't really need it but better safe than sorry.

Re: Tantung parting tool question.

I maxed out my RPM's today, all the way to 1400, and kept the feed at .0012 per rev. The tool ran like a champ. I'm going to bump the feed up to .002 and if it seems to tolerate it well I'm going to be well satisfied. I ran a carbide insert tool quite a bit when I did this for a living. For my curre...

Re: Tantung parting tool question.

Well I finished my new parting tool holder today and tried out the Tantung blade for the first time. I increased my old Red Cut Cobalt cutting speed from 360rpm to 1000rpm at .0012" per rev and my cut time per piece is down to 16 seconds flat. This tool is amazing!!

Tantung parting tool question.

I make lots and lots of interrupted parting cuts in annealed 4140, mostly in 1/2" and 9/16" material. Recently I purchased a couple of 3/32" Tantung parting tools and I am wondering about the speed and feed. I have no experience with this tooling and need a little guidance. My lathe is a Grizzly 12x...

Re: Switching From Mill to Lathe to Avoid Endless Chips?

I don't run the lathe fast enough to throw chips very far but I keep a steel hook handy to break off the endless chips - it gives me something to do while waiting for the lathe to do its thing. Now if I could just find a way to stop it from spraying hot chips while I machine brass! Hold a chip brus...

Oil it til it drips, then oil it again.
