Cutting gears

[Rare Scottish Tree Badger]

I took my 2nd, 3rd, and 4th gears to two machine shops today to have the 3 out of 6 dogs cut out of each, but both shops said that their mills would not cut the hardened steel.

 

I know it's possible, but how? ... On Mp350's website (Roostfest.com), he had the same problem and says he had to use a machine shop with an 'EDM'.

 

So, what's an 'EDM'?, and what other ways are there of cutting out these dogs?

EDM = Electric/Discharge/Machine

 

Reverse plating process, etches metal away in a controlled manor.

Thanks, RBD. ... I found out today that it's also known as a "Spark Eroder", unless that's just a UK term.

When i got mine done they milled them with a carbide endmill, but an EDM would be good too

Cheers, rebel... I just got an email back from Mp350, and that's actually how he got his done too. ... End Mill with a Carbide tip.

 

Should make for a neater job, not that it really matters.

I did one set of gears for someone. I don't even remember who. I used a solid carbide endmill. Actually, 3 of them. Them gears do NOT like to be machined. An EDM is the ticket.
