How to make this part?

[ztimbo]

Hi all,
I'm in the soap mould making business. I recently have had to out source some very detailed logo's.

Does anyone have a clue as to how this part could have possibly been engraved. The material is 940 bronze alloy. The letters stand about .025" high. My lack of experience is killing me with figuring out how this part is made. I don't have a high enough spindle speed to turn a small enough end mill fast enough to do the engraving with.

I've been checking into laser engraving but have not been able to find a company that can do this. This same amount of art work must also be place on a curved surface, similar to the shape of a saddle.

Sinker EDM. The image is CNC milled into the electrode. Did that kind of thing in plastic molds all the time before retiring.

I know very little about EDM stuff. Correct me if I am wrong but isn't the electrode graphite.

If so, I could see how the graphite is easier to machine but I would still have to machine a negative of the part correct?

I would still have trouble machining the intricacy of the part. The smallest endmill I have is a .016 which isn't small enough to do all the detail.

Could you explain in more detail how I would do this?

I was told by the guy who built this part it was not done by a mechanical action. He said he was using a "photo engraver". Does anyone have an idea of what he might be talking about?
