    I've seen good & bad examples of milling cutter bodies from Iscar. We had to quit using one line of their milling cutters, because the inserts would not seat in the pockets correctly when you...

    Wow. What a miracle that thing went out the back, and that no one was in its path. I doubt anything short of a .50bmg would have penetrated as many barriers that did - probably safe to call it a...

    I actually don't think it's insert related. That's a big boring bar - you can still take "finish" cuts with a medium/roughing insert.

    I'd check to make sure something's not loose.

    Is the...

    I've done it all {*I think*) but it seems to be the quickest, easiest for the boring bars. Most of the boring bars have a thru-coolant hole, but that means the block has to be sealed, or you have to...

    Yes. We plugged those holes with bolts, and drilled/tapped new holes in the blocks that intersect with the internal coolant holes, and tapped them 1/8 pipe. We usually plug one side, and install...

    I tried Evernote, but couldn't get into it.

    While I still don't used these types of "note" apps all that much, OneNote seems to work well enough for me. It offers some pretty slick stuff on the PC...

    Try giving an X value after your "G1 Z-61." move. Perhaps the machine can't define an area/contour within which to cut...? Will a G70 cycle run with the same P/Q path?

    I think it would be fine. Every bearing spec I've ever seen lists a higher "static" load vs. it's rotation/moving load, so I think that would fine. Plus, whatever shaping cut you're probably going to...

    For those wondering, these inserts are single-sided. After doing some research, I don't know if we'll be trying the roughing tools for cost reasons. We're a volume shop, so cost-per-corner and/or...

    On de-vibe bars such as the Seco & Sandvik tools, I don't believe there's anything special about the bodies. Probably just a generic, medium-hard tool-steel. Like I said previously, the "damper"...

    I worked for Seco for a while, and they pride themselves on their "Steadyline" anti-vibration tools. Probably the best anti-vibe bars on the market for milling. (Per my customer's testing &...

    The #1 critical thing with parting & deep-grooving, is indicating the blade/tool parallel with the X-axis. Most people will just throw a tool in, and never check to see how straight the tool is....

    My boss and I were talking about them today. There's a small chance that I'm wrong, but my best guess is that these are a "flavor of the week" cheap/basic machine, sourced from some factory-for-hire...

    Man, I gotta say, grooving is one of the more challenging tools to spec out. One of the worst things I had to help customers with when I was in sales, was spec'ing out face-grooving tools for lathes....

    I ran this code in one of our Mazak lathes. Ran fine with cutter-comp turned off. (Parentheses around the G42.) Using a .0156" radius in quadrant 3, it would not run. Putting a .008" radius and the...

    We have (3) QTS350 lathes at work. If you're planning on doing lots of boring, I'd be suspect of Mazak's iron. This is anecdotal, but our machines have trouble with chatter when boring. I think some...

    RE: Max RPM with a chuck... I don't think I've ever used a lathe with a chuck up to it's max RPM. Man, even our Mazak's w/ 12" chuck will spin to 3,000 or 3,300 rpm... Way too fast for a part held...

    If your idexable drill won't drill off-center, then you bought a turd of a tool. A .790 hole with a .750 drill is only .020 off-center
