Years ago I worked a ultrasound equipment manufacturer, one client
wanted a lathe tool holder modified with our ultrasonic transducer to
vibrate the tool 40,000 to 600,000 times a second. The amount of tool
movement is small (micrometers) and adjustable. The job was never completed.

Is this something that is in production?

Do you see how it would help in cutting.

What was it supposed to do? Reduce chip welding? Help with breaking
chips?

I've experimented with one of these entirely mechanical devices:

The oscillation is axial and the amplitude is pretty small, on the
order of a few tenths to a few thousandths. But that's in the range of
the feed per rev of a gun drill, so it's effective at thinning and
breaking the chips.

So how well did it work?



I watched the video, That could have been the idea behind the
ultrasound applied to a cutting tool. I seem to have a memory about
cutting extremely hard materials also.
Others seem to have shown some ignorance on the subject, but that's ok,
it is only because they are ignorant on the subject. So they poke fun.:-)
