Solid cam damage diagnosis help

When I visited Comp on Democrat Rd. In Memphis late 70s they had about 6 Bercos... that's it.

At one point not too long ago they had 13 Bercos running, and when things were really hopping..... running two shifts.

They also had a few CNC grinders at the same time.

Since then, I think they have maybe stopped using a couple of the Bercos, and have added more CNC capability, along with the capability of being able to produce a cam from a piece bar stock, including tool steel.
