Notes from the Editor’s Desk

That’s Gold and Silver!

David from Nagahara Flutes sent us this picture. Probably the most expensive pile of swarf that I’ve ever seen.

From David: “We use speeds and feeds similar to brass for silver. Gold is a little harder, especially 10K. I’ve been told it is similar to Monel. Silver is “gummy”. This is not a problem with our Tormach mill because we’re not removing much material in any of the operations it performs. It’s a big problem with our turned parts. We make all of our CNC turned parts on a SNK Prodigy gang tooling lathe. The challenge there it to keep the shavings from balling up around the work piece or cutter. Chip breakers don’t work with silver.”

Nagahara Flutes has been on Milling Around before, with a cool custom screen set for Mach3 to automate tone hole machining for different flute models. They make flutes for world famous musicians, including this 20K Gold Model.

Got this Tip from Alibre a couple days ago: Using Guide Curves with Sweeps

And Finally, the “Knack”

I’m sure Dilbert fans have seen this before, but it was new to me. It explains a lot about what makes Tormach (and our customers) tick.

Thanks to Scott of SDM Fabricating for passing it along. He definately has a terminal case of the “Knack”.
