I have made a micro small ball turning head for the lathe, does anyone have a simple COC for tool geometry? and while your at it whats the secret of getting the diameter precise.

Thanks...

Forgive my ignorance but what does "COC" mean?

coc= cRAP-OcAD - A hand sketch... a simple drawing an idea, a clue...... nothing fancy..

Anthony..

Oh, COC. That's how I design everything.

The way I set my ball turner to cut a specific diameter is to make sure that you are measuring from the center of the pivot point of the ball turner. I use gauge blocks on a surface plate to set the tool.

Here is something I learned the hard way when turning balls with a shank. Hope tis pic clears what I am trying to say...Bob
