Nothing too CNC intensive. A bunch of window type deals for some vacuum/lab type equipment. Some sort of extraction process. Two sided machining. Small shallow gland dealy on one side then that double bevel on the other. I didnt know the application or how they were clamped when the sample was dropped off but a clamping ring goes around these and the bevel faces are what compress a rubber seal that registers in the small gland on the flat face. Edge profile surface finish not critical.
Always fun to get to do something different once in a while.
