    I take it there's no way to get into the feature with the putty?

    I've only ever used the putty, never had problems with bubbles forming. Maybe I've been lucky, or is the putty perhaps less prone...

    Just the other day while I was not really paying attention to it, Youtube decided to play me a video about artisan soap making.

    They added rubbing alcohol to the mix to stop bubbles forming as the...

    I have one big machine (ram gantry) with an integral motor spindle. It has experienced several coolant leaks on top of the motor with never an issue. Can only speak for the one I have, but it seems...

    I connected it through the spare line receiver on the io board and it's working properly. Cabling is a bit messy due to having to split the harness to route it to three different parts of the...

    An RS422 receiver would work fine, in effect that's what the line receiver on the extant IO board is. I was just hoping to find a plug and play solution to save some time.



    I'm guessing that...

    Yeah, if it was a physical encoder that would usually work, and that's how I tried it initially.

    It's a generated quadrature output from the servo amplifier, 5v differential. Max. positive voltage...

    The old tenth-set heads are a big step up from the basic criterion type heads, and a solid option if your budget can't stretch to newer precision heads.

    I swear by D'Andrea TRM heads, also...
  8. Encoder connection - differential to single ended converter

    Is anyone aware of an off-the-shelf converter to condition a differential encoder signal to a single ended one?

    Standard 3 channel A, B, Z.

    I found a nice din rail mounted one that would be...

    FWIW (not much..) the technical sales guys I spoke to at NCMT (Okuma UK) swore up and down that they'd never heard of chuck sensors operating like this and that any new Okuma lathe or millturn we...

    Thanks for the answers. We declined this, but I'm going to continue to ask around so we have some solutions for next time.

    I really don't have any intentions of trying to machine this to...

    I am quoting a plate part, ~350mm sq. It has one square corner, but the opposite two sides are tapered outwards and blend tangent to a large radius.

    Finished thickness is 12mm +/- 0.2mm, but...

    I've said it before many times, but reamers are generally an absolute last resort for me. They rarely ever cut the exact hole you want them to, sometimes close, sometimes not. The coaxility you...

    On a collet, any collapse from nominal throws all guarantees of precision out the window. That's why all the high end systems are nominal only. Even on ER, the high precision collets are nominal...

    This is the crux of the problem.

    We've been trying to expand for years, but getting people who are actually competent beyond basic machining is just impossible.

    We were cutting 36CrNiMo4 quenched and tempered which is more or less 4340V. We were running pretty wide open, because the LNMX wouldn't break a chip in that material unless the feedrate was right at...

    I played with LNMX for a little while, they were great for shifting material, but predicting insert failure was difficult, and losing an edge took out the holder every time before the operator had...

    Supposedly, the PRM function was introduced for this purpose, but it your control is probably too old. It doesn't work on any of mine, so I don't know which controls actually support it.

    People make this argument every time someone asks this question.

    The point people overlook is that yes, programming a lathe is simple, if you're making basic turned parts.

    There are any number...

    Is it possible that it requires a P value even though there is only one spindle?

    i.e.

    G10 L50
    N4077 P0 R800

    While I was thinking about replying to another thread (https://www.practicalmachinist.com/vb/cnc-machining/fanuc-18i-mb-spindle-orientation-g10-365630/) I came across this quandary.

    I machine a lot of S355 and use insert drills all the time, usually with through coolant, but sometimes without.

    S355 comes in a lot of grades/conditions that all behave a little different....
