    Seemingly Impossible task, Any Tips?

    It'll work with a 5/8" tool custom ground with an 8.9" neck length @ 0.575" diameter, and 0.100" effective flute length. OAL = 12.25". Helix down at 0.015" pitch. The minimal flute length and fine pitch helix will greatly minimize vibration. It'll just take a long time as previously stated...

    Clamping Large Billets on Horizontal Machine

    At 3.5" thick, I think those 2-piece vises will work fine. Somewhat similar to VTL chuck jaws I've used in the past. I've machined 60" diameter x 2" plate with no issues.

    Tormach's revenge

    No mention of accuracy on the machines or the components...? What kind of real world tolerances can these machines hold?

    Concentric Drilling/Reaming

    Drilled holes are never that straight, hence the need for a boring operation. Yes you can. Just need fiddle around with it a bit to get a flute on center. This will get the ID concentric with the OD. The reamer will simply follow the bored hole, increasing diameter without affecting location...

    Brand new machine tips?

    Had to look it up... VTL style turning with 1250mm diameter table and 2100mm swing. 5-axis milling and grinding capability. Hell of a machine indeed. I'd start with the overhead crane and meter-thick concrete foundation.

    Joe Biden calls for tripling of tariffs on Chinese steel

    Tariffs increase material prices across the board. Basic supply and demand: if the demand for Chinese steel drops due to tariffs, the demand from all other sources rises. Supply doesn't react quickly enough and prices go up. The only way domestic pricing doesn't go up is if energy costs are...

    CNC Lathe - Setting Y value of cutter

    Lathe tool presetters cannot check for Y axis deviation. You set this by eyeballing and test cuts.

    Modular Endmill Extension (screw on head) Brand Compatibility

    Are all those brands in the IMC group? E.g. Iscar, Tungaloy, Ingersoll, etc?

    What is EDM wire made of?

    Brass wire is typically 60% copper, 40% zinc. I don't really bother with coated wires since it typically only speeds up the first pass, and everything I run is 3-4 passes, but coated wires are going to be something like 80% copper, 20% zinc, with additional zinc in the coating. Not...

    Hass Mill tool probing (VPS) question

    Probe length by itself, write down the number Probe length and diameter, knowing that the diameter will be correct but the length will be wrong Overwrite length with the original value you got from step 1 VPS routines help you save time but they don't cover every possible scenario, as you've...

    I have a 2023 DNM5700. Is the coolant/chip management really supposed to be this terrible?

    Turn down the coolant flow when running 3D surfacing tool paths. If the main coolant line splits to the spindle and washdown, turn off the washdown. I've run into similar problems on a multitude of machines and this is the only solution that consistently works.

    Mastercam Automation

    Do you start from scratch each time? When creating a new part file, I usually open an existing, similar part file to use as a template. Save-as-new, delete all the old geometry, drop in new geometry, reselect geometry for each operation, and delete the operations I don't need. If I need...

    4 X Diameter in 304?

    Can you apply cutting oil by hand? I'd go for it.

    Tool Recommendations wanted for small high feed mill in 316

    Which insert geometry did you use? I like the JM and JL geometries. The FT and ST geometries absolutely hammer the machine. In your previous application where your stepover was 1.1", what was the cutter diameter? High feeds are happiest with maximized stepovers. You get a wavy surface, so...

    Variation in 1018 steel causing issues with insert drill

    Durabar is owned by Charter Steel, but their plant is completely dedicated to cast iron. Take both the feed and speed down to 70% and then creep the feed back up.

    Precision Degree in the ID

    Makes sense, especially if they plan on making an assortment of different nozzle diameters from the same basic part. My EDM experience is limited to wire, but I agree with @implmex that sinker EDM would be the way to go for finishing these parts.

    Transition from low volume to production

    Can you pad some leadtime on the production jobs so that you can squeeze in a few emergency jobs for your existing customers here and there?

    How does this function if there's no thru-hole?
