    Our VF5 runs on a 40A breaker @ 208v 3-phase. No issues.

    Using a breaker smaller than the nameplate rating is rarely an issue since the machine never pulls a constant full load. The breaker...

    Try a fresh toolholder and make sure the pull stud isn't over tightened, as that could cause one end to bulge. Use a quality holder like something from Maritool.

    I guessed 304 stainless before even opening the thread.

    The material is notorious for being inconsistent, and similar questions pop up here a few times a year.

    316 is superior to 304 in...

    If push comes to shove with regards to your budget, you will not regret getting a bare bones VF2 over a well optioned MM2.

    IMHO.

    Straight radial live tools designed for 10-12K RPM have the obvious advantage of not having any gears at all, and will go a lot longer before requiring a rebuild than a 2:1 speeder.

    Knocking on wood, the Iscar Tang-Grip, 3mm width, IC808 grade is the only parting tool that I have yet to kill.

    How much stock are you leaving for finishing? Weaker machine: leave less stock, or just deal with the spring pass.

    Hitting the diameters is one thing, but hitting the diameters while maintaining concentricity can be much more difficult.

    How big are the ID and OD exactly?

    Sometimes an otherwise excellent finish can be spoiled by chip dragging/BUE. PCD should help eliminate this.

    It's not that a single wiper can't be used in the R590, it's just that it might be redundant/unnecessary if all the other inserts are dialed in within a tenth.

    Aren't you able to dial in each insert individually with the Coromill 590? Wipers are generally for cutter bodies that don't have that feature.

    Same.

    There's no easy fix. A well packed birds nest will jam up almost any brand/model of conveyor. Just gotta be diligent.

    My guess is that Sandvik believes the next big push in CNC machining is going to be driven by software.

    Some riggers will remove the factory wrap except for a light layer of plastic, and then use their own tarp/blanket. It saves them time and they...

    High feed cutters put cutting force mostly in the axial direction, so gauge length is less of an issue.

    They're also less affected by runout and don't require massive gripping force.
