I've got a client which need to have punch tips engraved with small logos for punching wood and plastics. Those are REALLY small... kinda 3/8 to 1/2...
The guys who does the job usually charge 200$ per punch to do the job but has a 100,000$ machine... But here is the winner, this client need about 60 of them and more in the future. We have a great relationship so if I can deliver this job I'm probably good to keep the shop open as it will bring steady job.
Can someone give me an idea of how it's usually done (machining wise). I've got some fine tools and am currently building this machine:

I have my 3 axis router to cut parts which help a lot and if needed I could build a machine that does 2 x 2 x 0.5 and have 0.001 precision too.
I need stiffness that my current router does'nt deliver for the steel punch engraving. It's about .03 high with a ring all around.
I'm essentially into verifying how I can machining the part. It's one drawing, but many units... If I can get the contract, I don't mind doing a rfq for the CAD itself...
Can this be engraved/machined or it need some kind of other process?
Might try making a stencil, mask the area with ceramic and sandblast? Your tought on this?
