So here's the thing I made. A titanium pendant frame for a girl at work. Some sort of large insect from java will be encased in it with water clear plastic. The part is unfinished other than deburring. This is the first time I have done anything other than ring like items on the lathe and anything other than engraving on the mill in titanium. Machined very well. Does leave some nasty splinter fragments though.

I am including a link to the video on youtube. You really need to watch it full screen due to the size of the part being machined and how close I can get the camera tripos to the machine (Just an iphone).

First part is doing the pocket. ~3000RPM at 8ipm, second is doing a re-machining of the corners and a finish pass around the inside, third is spotting, fourth is drilling the holes for fixturing and casting, they will be covered by the bug.

After this I took a piece of sacrificial aluminum, face milled it, drilled two holes (While crashing the machine) to match the ones in the pendant, and tapped them 6-32. The pendant was screwed down to the block. The last section is cutting the contour around the outside.

Looks good,that sure turned out better than the way it started:)

I was always told a crash isn't a crash unless you need a Stillson wrench to back the lead screws off:eek:

Nice work, but I don't see how you can stand to have your tools sitting on the table amongst the chips and coolant mist. Especially for the spindle tooling, I would think you'd get tired of having to clean the tapers every time you changed tools. (At least I hope you clean them.)

Very nice. The cuts probably would have made more sense to me if I had read the post before watching the video, but maybe I learned more watching first.

Nice job.

Quick wipe with the hand cleans off anything and I would be doing that even with a tool holder off the rack which is over full. And the coolant creates almost no mist, its well confined to the target area.
