Would you believe it? It's actually finished and was used for a first project yesterday! I don't even want to check how long ago it was that I started this project. Far too long...
There are no visible differences to the last log post (except for for a retractable arm holding the interface laptop), so instead of another picture I'll start with some video action:
First ever project was pocketing some hardened stainless steel. After a few slight issues the end result turned out amazing. Zoom in on this picture to see the surface finish:
I'm really happy with the rigidity and minimal backlash of the machine, it handled this tough material well. The only real disappointment was the milling spindle. I knew a cheap high speed spindle would have issues machining steel since it requires lower RPM and higher torque than aluminium or plastic. But with a 2,2kW spindle I didn't think a 5mm endmill would present such a challenge.
Still, I expect I will mostly be milling aluminium and hopefully it will rip through that like butter. The recommended speed range is 8000-24000 RPM, and I was trying to cut at 4400 RPM.
And with that I declare this project completed! Although I may still post more logs with upgrades, modifications, or maybe just to show another milling project. This started out as one of many big projects I have initiated, but ended as one of the few I actually finished. Fantastic!
