I've been machining all sorts of stuff, things are going really well. I am dialing in a lot of parts that I made in the past as a result of the tool changer. Since I am no longer worried about being there to change tools, I run all sorts of finishing ops with devoted finishing tools. Luxurious!
I need more TTS ER20 holders and that supply chain looks like a mess, I am not sure what I am going to do there.
My PM 1127 lathe conversion is starting to cook. I have been making a lot of stuff on the lathe, I have a few parts to cook up for the mill. Then, I will do the servo conversion on the mill as well install the new spindle, new ATC parts, and just generally clean and adjust it. The steppers will come off, they will go on the lathe. I haven't decided what control I am going to use on the lathe. I am torn between Acorn and LinuxCNC. If UCCNC had a lathe control i'd do that without hesitation,.
As for feeds and speeds. I have been shredding it lately. Running at around 5 cu/in/min with 3/8" 3 flute ebay carbide in Aluminum. The thing is incredibly quiet at those speeds. Tool life is great too. With finishing tools on the tool changer I get to come back through and clean up with really nice finish and tolerance. As we know the 0704 is a bit loose, so for finishing runs I like to run the machine at about 1/3 the roughing pace.
