This is my first post here. I work where we use many small circular aluminum pieces. They have a smaller half circle cut out of one side of it (see attached image). These things are expensive and only available from the manufacturer. They are $700 for a pack of 300 small pieces of aluminum foil. We have been able to find a suitable aluminum foil for our needs. Is there a way to cut aluminum foil with some sort of laser engraver or cutting machine? If so, what would be the best one for my needs? I am new to this world, but I have some working knowledge of a CNC machine.
For clarification, the OD is 37mm and the ID is roughly 32mm.
