Hi,
I need to make a few adaptors in 5mm spring steel (piano wire) and have run into
a problem, the parts are very simple being a 4mm section around 4cm long with
the rest of the 6cm overall length being left at the stock diameter.
The original plan was to use brazed tip tools to turn the parts but the very
first attempt to part off a length of the wire broke the tip off the parting
tool. The material did seem to be machining OK up to the point the tip broke
but I think the flexibility of the wire led to vibrations which got the better
of the tip. My only other turning tools are HSS and although they will
obviously be tougher I wondered if they will be hard enough to maching the wire
in its as supplied (springy) state ? I don't have heat treating facilities and
so don't want to attempt the anneal, machine, harden and temper cycle.
Any ideas ?
Thanks,
