Didn't see a drop of cutting fluid; maybe modern day machining gets by without it?
Uncle Buck sold for Morse Twist Drill. When he passed Dad flew out for the funeral and to be with his sister in her time of need. When he came home he was lugging about 75 # of all kinds of bits and cutting tools, some of which I still have no idea how they were used. Quite a few specials too. It really gave me an appreciation for the machinists who knew just how to get the most out of their cutting tools as well as the designers who went from concept to finished product.
Nice video, nice cutting conditions, depths of cut and feeds. No coolant for the video, and some materials don't require it, of course. And no sound either, that would be instructive, perhaps not possible with slow motion. But slow motion makes it all look a lot more elegant, doesn't it? Very nicely done, I will show my students when we return in August.
I wonder why that drill in the next to last clip has that rough patch on the back of the flutes? I'm with Phil, there is magic in this trade. Very satisfying to make parts that fit and work, and bring older equipment back to a useful state.
Those cutting heads are pure works of art in of themselves!

Great video.

ReplyDeleteFeeds and speeds, baby! And lubrication when/as necessary...
DeleteTo be truly soothing the video would have shown the finishing of an 80% lower.
ReplyDeleteThis.
ReplyDeleteIt will fascinate me until the day I die.

ReplyDeleteIt used to be true that the vertical end mill was the only piece of equipment that you needed to build a vertical end mill.
ReplyDeleteI love high-speed photography, and this video is one of the reasons. Next to the 1 million FPS of bullets striking a plate, this is mesmerizing!!
ReplyDeleteI took a close look at the chips/curls as they were coming off the cutters, and could actually see some chatter!
