Linky Page 22 start the Article.

 

For those looking for more information on the benefits on this process here you go. I started doing this around 93 or 94 and have always seen the benefits of doing it. Hope this provides some insight for others.

Hi Crazy Millman,

I helped in the development the Hard Turning, Boring and Facing of gears back in the mid 80's for Mercury Marine. At that time we use ceramic tooling and a pin plate with jaws to hold the gears on the lathe. The savings were astronomical over grinding. We used cubic boron nitrides (CBN) inserts to face off the teeth of the gears. At that time the cost of (CBN) tooling was very expensive. So we only used (CBN) for interrupted cutting and over welded steel and stainless steel. From the looks of the article things have really changed. I enjoyed reading the article it was very good. Thank you for sharing it with us.
