We don't use sirona, however with our system we stopped using the systems tools and when with a third party. We have eliminated chipping almost totally, and the tools are now in use 3 times as long. As for the chipping it might just be the mill itself. Try your spindle is it running true?

We don't use Sirona but rather Amann Girrbaach. I occasionally get a chipped margin but it is usually due to dull burs or someone touching the machine during a program. If you are using fresh burs and the machine is calibrated properly, I question the quality of the bur and the spindle.
