Issues parting off

The problems with parting off are many once overcome the process works without fault. I have a Myford ML(speed)10 and part off 30mm bar with no problem even from the front.
Fist the bearings must be in good order, second the parting tool must be sharp, ON CENTRE line, Square on to the bar and the speed correct. I find that changing speed as the diameter reduces helps. Use a light cutting oil and proceed with the cut in asteady motion. All the slide must be clamped to prevent tool wander. I use a combination of tools - The Quick cut from Greenwoods, groud HSS (square stock) and quality parting blades. 7deg top rake works for me. I'm about to make a tool holder like the Geoge Thomas/ Ian Bradley design so that I dont have to cange tools.
Hope this helps
Phody
