I have a MaxNC 10 Closed Loop desktop mill and it has been a pretty decent machine. I have been cutting primarily machinable wax. I would like to "extract" a male plaster pattern from a CNC machined cavity in wax. Does anyone have any experience doing this? I have tried numerous lubricants and nothing works. As soon as the plaster dries it does not want to eject from the wax cavity. Should I be using something other than wax? Should I create some type of ejector pin?
Any help from those experienced would be greatly appreciated.
