  • Cool hard turning video with sort of shear tool

    https://m.youtube.com/watch?v=2YA0CSA_sx8

    Never seen turning done like that.

    Everybody who watches that is probably thinking "What can I rig up so I do that on my lathe?"

      dang

      looks like a shear tool that they rotate slightly to use a fresh part of the blade for every bit of the cut.

        Was actually thinking of some sort rotating toolholder one day after seeing the Sandvik Y-axis parting tool

          I don't have a CNC anything but those 1000*+ chips would start a fire at my place.

              Lathe Skiving is kind of related process:

              Now I have to admit that I never thought of that!

              Or power skiving that looks almost like cut knurling:

              Bet that would make nice knurling every time without buggering the start!

                why would that be faster, or the y-axis parting?

                  I'll admit, I'm very confused as to why that seems to work so much better... I'm assuming that its something to do with the cutting force being directed along a stiffer axis meaning the tool can take a higher load, but I still feel like I'm missing something

                    Yeah, stiffer tool. Basically zero overhang from the tool itself and no flex.

                      I've already tried that sort of thing.

                        It's all about where you direct your force. if you can direct it in a direction that is stronger, you can then feed faster.

                        THe original video is cool, never seen anything like it. I bet that would be great for turning crankshaft journals, or other bearing surfaces deep between sidewalls. it allows a MUCH stouter tool to be used.
