    Unless it's buried in the small print that I can't make out, or behind the redactions, I don't think there is a material callout.

    Hey Denis, how's it going? :)

    Looks like you are making lots of chips with regular smooth-flute endmills. I have seen issues where a little foaming in the coolant can cause the feathery chips from...

    The first time you 3D surface something with a ball or bullnose, you will wish you had more RPM, regardless of what you currently have.

    Ha ha, most Xometry jobs are due within 3-8 days of offering, so that's a non-starter. For most of the Xometry jobs I see, if I don't already have the requisite material on the rack, I don't bother....

    Aye, yes, that was me last year. My "crew" is me, but the scenario is the same. Most of the Boeing work dried up, we can't travel, so what else am I going to do?

    Agreed though, the minute my...

    There's Colorado, and there's Colorado. Berthoud/Johnstown isn't Denver. No, you're not going to have a loft in Boulder, but I think you could do OK if you kept to Johnstown, Milliken, etc. There's...

    BTW, you have 22 tools and lightning-fast tool changes -- why fret about saving a tool pocket or tool change?

    That would defeat a lot of the benefit of a double-angle cutter -- being able to chamfer an edge that has limited Z clearance due to vise jaws or other part features. Yes, you can chamfer with the...

    In 6061 ... 16,000 rpm, 3-flute Destiny Diamondback EM,1-1/4" axial engagement, 35% radial engagement, 288 IPM. The spindle motor will handle it, but the toolholder gets shaky in the taper.

    For chamfering, I like as many flutes as possible. I also like being able to chamfer with only ~.02" of the part proud of the jaws. To that end, my regular chamfering tool is an 8-flute 3/8" Harvey...

    No, just mind the % engagement and feed rate so you don't generate so much downforce that you pull the toolholder off the taper and get some fretting. Maybe the R450 has more drawbar pull than my...

    RPM? Feed? Stock diameter? What HP does your machine have?

    1/2" DOC -- is that on the diameter or the radius?

    Yesterday I was taking .10" per side (.20" on the diameter), 2,000 RPM, 3-3/4"...

    Yes. The carbide gets really hot really quickly, but since it's in and out of the cut relatively quickly (compared to high-engagement "plowing-style" cuts), it spends...

    Um, maybe you were here for a very unique 18 months. I've been here (15 miles east of downtown Seattle) for 24 years, and it totally rains a lot in Spring and Autumn. The frequent (albeit light) rain...

    I overtraveled my Mori Seiki SL-2B which is usually not a big deal, just jog off of the switch and clear the alarm. But today I'm unable to clear the alarm even after moving the Z-axis way...

    Could be something that was case-hardened. Try half the speed and 2-3x the feed.

    What shape and color are the chips?
