hey guys,
i'm turning some powder chrome parts right now. I'm having some issues, because its burning through my tools. What type of feed and speed should I be running? The part OD is 1.25" and I'm using carbide inserts. I can't use coolant because it might contaminate the material. I'm spraying deionized water on it from a spray bottle as its cutting. I'm getting a crappy finish and its killing my inserts. Any suggestions?
Thanks!
