    I discovered how little pressure a sharp HSS tool exerts while roughing a shaft. For some reason I bumped the tool between cuts and found I had forgotten to tighten it in its holder!

    I am going to do this to my shop lathe.
    Thanks for the education.
    I think that the final .0005 could be the live center.
    Still very good tolerance for a lathe.

  • @ianlangley987

    Hi Max, You are coorect about the CNMG style insert being stronger than the TNMG style. Its simple as the TNMG has 60 degree included angle corner where as the CNMG has 80 degree inclduded angle along with greater support behind the cutting edge. That what makes it stronger. Enjoyed your clip on adjustment and I could see exactly where you were going. The big thing I have found when making these sorts of adjustments is to move small amounts with the screws. Cheers Ian New Zealand

  • @CraigsWorkshop
    @CraigsWorkshop Před 3 lety +1

    It's very satisfying getting the twist out of the bed and getting the headstock and tailstock lined up. My lathe bed bolts to a steel box cabinet similar to yours, and the cabinet sits on concrete, with levelling feet I made. I found that the cabinet was too rigid for the combined weight (440kg) and instead of the levelling feet twisting the bed, it just allowed the whole lot to rock. So to solve this, I shimmed between the lathe bed, and the cabinet, this straightened out the bed, and let me put even pressure on each foot on the floor. It was only a bees dick out of parallel, but it's nice seeing the bubble central on both ends of the bed. Thanks for the video Max, great info, particularly the reminder about tool cutting pressure and workpiece toughness throwing your diameters off. Cheers, Craig

    • @kaiok1777
      @kaiok1777 Před 3 lety +1

      You might have a chance if you choose a small nose radius 0.4mm or less, take a minimum depth of cut roughly the same as the nose radius, use good insert geometry (positive rather than negative and with a high rake) and set a high feed.

    • @aubreyaub

    • @swanvalleymachineshop
      @swanvalleymachineshop  Před 3 lety

      The depth of cut has to be deep enough for the chip breaker to work regardless of the nose radius . A small lathe you will have best results with a small nose radius so you have less depth before the chip breaker comes into play . If a Koala falls out of a tree and misses you it's just a Koala , if it hits you it's a Drop Bear !!!

      Just for clarification, how does a decimal differentiate imperial from metric? Last i knew .5 of anything is still half...be it an inch, millimeter, mile or kilometer...

      @@bobluthier3031 Yes you dont know. Im also not going to explain it further to people who are stuck in their ways and unable to comprehend anything else. The fact that you cant put it together says everything as to why you arent getting the decimal issue being used in metric. Tough cookies. Believe whatever fantasy that makes you complete. K? Good!
