I just tried out my new parting tool from Soba being sold by Chronos.
New Clamp Type Parting Tools with Chipbreaker Blade
I am really impressed how well it works. The blade is a T shaped and has a U shaped chip breaker ground into the top. This means you only have to grind the front face to sharpen it, and the tool is held horizontally against the work.
Setting the height is a puzzle, top or bottom of the U? I decided to go for the bottom. My first test was to square up the end of a 22mm brass bar. I managed to cut about 0.5 – 1mm thick slice off. OK it deformed into a saucer shape, but the end of the bar was nice and square.
The swarf came off as a long ribbon and I had no squeal, I think I could have even used the power feed.
I bought the 10mm blade version, it is a little small on my lathe. Soba also make a 1/2" and 3/4" version which Chronos don't stock but I hope to get sometime.
Adrian.
