More fun with the camera today.

Here is some 3/4" hex aluminum at 420 FPS. I am sure some of you can find a few things wrong with the cutter.


There is allot more where that came from.

Any Requests?

Hi Kel, it looks like you could use more top angle on the tool. It's peeling of kind of gummy like. What kind of aluminum are you cutting?

Is it my imagination,or is one of the flutes not cutting?Intriguing to actually see what's happening,makes you aware what a hard job an end mill has to do.

Hans, I think your right. It could be because the end mill is being held by a cheap Chinese drill chuck.

I read this as a cutting speed of 420 feet per second and wondered how you got your lathe to run so fast.
then realised it is frames per second,

That engine is a v-4. 5/8" bore and 1/2" stroke. I will explain more in my post about them.

Wow, that endmill movie was really something. Thm: I liked the music, it sounded like something off of Charlie Brown, which always reminds me of my childhood.
