To avoid confusion, it's worth noting that only
swiss screw machines move the stock. Regular screw machines do not.

The tools do not move in Z - there's no way to crash them into the spindle. There's a small bushing that the stock goes through, and all the tools are arranged around that hole. On the other side of that wall is the spindle and headstock, which provides you Z movement.
