Most low-tech/low-cost way I know of being repeatable, reliable, etc, is turning the shaft to diameter (lathe) and then splining it one spline at a time in a rotary index on a mill.

4th axis? i don't think you need a 5th for cutting splines:D

:homer: I thought thats what the guy at the shop said when I had some spline cutting done.

but maybe it was the beer we drank after thats fogging my memory...

I've been looking into this, too. As posted a 4th axis on a vertical mill will work. Those rotary broaches are awesome. They are also mondo $.

Do you plan on doing a hundred of the same splines or just one here and there, whatever it is? I think you'd be better off with a mill in any case. It's all in the tooling. I am still building up my machine shop at home and the machines are only 50% of the cost so far!

It could, but you could also do it with a file if you had the patience, maybe even a chisel.

:laughing::laughing::laughing:

I think a Dremel tool with a thin cut off is the way to go. :D

As was mentioned before you need a lathe - and I'd suggest a very substantial lathe becuase you will be hard turning the shaft and the cutting pressures are very high. Here's my lathe:



For scale, that's a 12" 4 jaw and a CA sized quick change tool post. The lathe doesn't need to turn fast, but it does need to be really rigid. I use a live center and I also use the steady rest to help fight chatter and limit deflection of the axle shaft when I am cutting.

You also need a mill, a spline cutter and an indexer.

here's a post where I explain how I did it the first time:

I've upgraded since I made that post (it's been almost 4 years). The first upgrade was to sell my Bridgeport and get a Gorton vertical mill and put a DRO on it and use that for cutting splines - WAY better than the horizontal for ease of use and productivity. The second upgrade was to cut splines on my vertical CNC. I'm still indexing by hand, so I basically run the program to cut one spline, index and then run the same program again until I'm done. It's a PITA though and between blanking the shaft and the actual spline cutting it takes over an hour. I generally won't do that job for other people, unless I owe them a favor or they have some good Jeep parts to trade :D
