Can you machine a CF53 hardened steel shaft in a lathe?

    Apologies in advance for what might be a very daft question, but is it possible to machine a CF53 hardened steel shaft in a lathe so the end tapers to a point? Similar to the two shafts in the picture below.

    Another options could be an aluminium shaft (EN AW 6061/6060) but I'm guessing steel would be better for the application below (wheel truing jig).

    Thnks in advance if you have time to respond.

    Yes. Decent size lathe and carbide tooling followed by toolpost grinder if you need the ultimate finish.

    No worries, I might even be able to quote for you. Be interested to hear how much a regular machine shop would charge but there are plenty of us on here who could do it for you.

    That is a very kind offer and one I will certainly take you up on. Currently in design phase, so will probably take me a few weeks to figure out which bits I can do myself and which bits I'll need a quote on. Don't have a lathe or mill, just basic engineering & metalworking tools.

    £45-60 an hour would be reasonable

    Im a regular machine shop and it would be £30 the pair if machining
    Hardened though looking at samples there are other ops so Id machine in annealed condition then harden

    Liking the idea of that. I'll have a search. Quick look seemed to show mostly tapered shafts. I'd need a parallel shaft. Cheers.

    Using CBN tips it is just a straightforward job. Plenty of feed and speed on and it wouldn't take long. Finish will be excellent. I will try to dig a pic out of one I did earlier.

    Yes, I was very dubious at first but I keep a couple in the "get me out of the Carp" drawer. There are always a couple for sale on German ebay that fit one or another of my toolholders and always at the right price.

    I had to look up CBN
    Wow. Though of little use to a Drummond M owner that is my informal education for today and it is not even 9AM. :thumbup:
