The part was already cut through. The material is sitting on a vacuum plate. You can tell by looking through the triangular holes. The white surface of the vacuum plate is visible. Once one side is complete it can be put on a standard lathe to clean up the other side (the other side is not shown in the gif). The equipment used is most likely a small CNC Router.
