hello ! there are about 2000 parts, each with 50mm total engraving length...
of course, i do believe that a mill can do the job, but i think that those Tapmatic tools are much faster and reliable not necessary Tapmatic, but the idea
now i prepare this part for production;i can go like this:
...rough this part +0.5 on 4 sides
...send it to a marking press, where all shape is marked at once with a poanson/stamp/or how is it called
...parts will bend after this, so i must straight them back ( maybe with a hammer ? )
.........or
...mark it directly ... i believe that this way i can save a lot of time
i would like to see those tools at work ... i will search if there are any arround my area kindly !
