Good day to all
I am having a chatter problem while trying to use my parting tool(cut off tool) on a mini lathe. It is a 7x10 lathe. The tool is a 1.5 x 5mm with the matching holder. The tool cuts well for a couple of seconds and then chatters, until the lathe shuts itself down. This is on 6061 aluminum. I have not tried it on other materials as of yet.
I have tried setting the tool on centre, slightly above or slightly below centre, all with the same result.
I have tried to use various rpm and feed rates, with little luck.
Almost no backlash in the cross feed (haven't measured it but is less than 2 thou on the dial)
Tried sharpening it a couple of times but no real difference.
Thought that a wider tool might be different but only have the one tool
Any thoughts?
Thanks in advance
Steve
