Hi All,
So I have a project where I'm trying to use a disc & bearing assembly to make some other parts. These are worn tillage discs, so higher grade wear steel, I don't know the spec but they don't drill or mill easy at all. They are about 15" diameter and 1/8" thick, with a 5/8 bearing. I'm trying to turn them down to 12" diameter, need to do 18 of them.
Now for the tricky part. I don't have a lathe, nor space for one currently. I have a Bridgeport mill, no rotary table. I tried to machine an arc with the setup shown. It's not rigid enough for the plunge with a mill, nor for the arc, wants to grab and break end mills.
Thoughts on how to set this up as a repeatable task with machines I currently have? What kind of tooling? Parting tool held in mill vise? Drill mills? Open to all suggestions.
Thanks
