The images below were taken from another gear related forum.
They are of a machine located at a gear shop in India somewhere.
A conventional milling machine is being used to do the job of a horizontal hobbing machine. Power is taken from the rear end of the horizontal tool spindle and then, through a series of change gears and a PTO shaft, is transferred to what-looks-to-be a dedicated gear box which just happens to look a lot like a dividing head.
The chap that posted the images was having trouble with getting a decent finish on the flanks of the spline teeth he was attempting to cut. It was hard to make out exactly what his problem was but it sounded like he was also getting a lead error.
I don't know what it's like in the rest of the world; but here in Australia, more and more one-off type jobs are being out-sourced to shops in India. I've know idea if those shops are anything like this one, but buyer beware!
