So I got an order Carter Tools the other day (excellent service), and in it was the small 3/8" shank fly cutter (1224ER). Tonight I got my mill all trammed (5 tenths over 6 inches) and decided to play with the Fly Cutter...
I've tried a variety of speeds and feeds, but not having any luck with the surface finish, its coming out fuzzy.
Spindle is set to the lowest speed (1000 rpm), tried between 1 IPM and 8 IPM, and about 3 thou depth of cut. Nothing, everytime it comes out fuzzy. Also tried climbing and standard, both end up with the same finish. Felt the spindle while it was cutting the last pass, it was smooth and steady no vibration, I don't think the spindle/column are flexing as these are really light cuts.
The bit was pre-ground, and quite sharp and, well, brand new so I don't think thats the issue.
Anyone have any experience running fly cutters on a Taig? What am I missing?
