Turning hardened steel

A friend of mine had to turn steel that had been hardened. I think it was about c50 or so. The insert is made for this but the metal coming off sure was hot.

You have to take real small cuts. The cuttings are almost soft like steel wool though. Very weird.

i love the smooth finish hardened steel/tool steel leaves after being machined

it would be a bastard if you had to take off 1/2 inch with a .005 cut each time

@andhija Not really, the heat dehardens the steel and thus the cuttings are just ordinary steel

Ever caught a chip on the arm??

Is the insert ceramic or a CBN insert?

WOW! I didn't think they made inserts to cut like that.

I would never want make a lathe do that, at least not while standing next to it.

Always Respect The Metal.
