  • It's alive, ALIVE I tell ya!

    Well everybody in the house is PO'd at me 'cuz all I've done this weekend is putz around with this dang little CNC lathe project but by golly it has now officially made some chips. I'll post a couple pics but then I gotta clean up and head back in the house with m'hat in m'hand and try make nice.

    I don't have any special lathe software so I just used the standard mill commands to move the Y in & out and the X left to right. I typed in some G01 commands to cut the taper you see in a piece of 3/4" 6061. It cuts smooth as heck and the treadmill motor just loafed along. The finish is GREAT even with a cheapy lil' carbide insert and there's no sign of chatter at all. My little toolpost seems to work fine.

    I have a long way to go yet to make a useful tool out of it but I'm encouraged that it actually cuts metal like it knows what it's doing.

        It doesn't use any extra bandwidth. The images are already in the browser cache.

            Wahoo! good on you DB I'm so envious.
            Hopefully I will have time to catch up in a year or so
            (I started a similar project couple of years ago)

              DB,

              That is fantastic, I can't believe I'm the first to ask for more details.

              Stuff like construction details, motors, ballscrews, everything. Let's hope you took some snaps from the beginning.

              I really, really like the concept, and wanna see more.

              Great project.

              Ken

                maybe not but,
                Doesn't it take extra time for the "real" photo's to load for guys like me with dial-up ? it seems that way?

                  Thanks guys, hopefully over the next couple weeks I'll get more familiar with it and make some useful stuff. 1st up is more toolholders and a truing up of the ER32 taper. Somehow it ended up with a bit of runout and I'm going to attempt to make it better via CNC controlled ID grinding with a HF pencil die-grinder.

                  Ken, you're probably the 1st to ask for more details because everyone else around here has already seen my endless posts about the thing and are probably saying: "Sheesh, enough already!" I've been working on it since last summer and have asked a zillion questions here about the many things I knew nothing about. Fortunately when I got close to crashing & burning Evan, Macona, MaxHeadRoom, Whitis and many others reached out and put me back on the path to success.

                  To save a bunch of typing, here's some links that shows the path of how it got to where it is now.

                    When you get it to the point where it will wash cars, and cook dinner, I'll marry it...
