Record Cutting Equipment Specifications

Perhaps someone can simply point me to a web page but I was interested in the specifications of the cutting equipment such as the ones used to cut the DCC vinyl or something similar. Is there any rumble? If so, how much? How much wow and flutter? What's the frequency response of the cutting head? or of the electronics leading up to it? And so on and so forth. I have no real use for this information but I am definitely curious. Thanks in advance.
