How many times can a flywheel be re surfaced?

Thanks, I did not know that. I honestly thought flywheels were turned on a lathe. I am working with a competent machine shop on getting that flywheel renewed, but I did not think to ask what process they use on flywheels. I will give them a call tomorrow.
I called the shop, they said my flywheel will be ready for pickup today after 2:00 pm and that they use a grinding process.
