    That is builder specific. The ability to ignore a T call when the T call equals the current spindle tool is determined by the builders ladder logic program, not Yasnac. Some builders will include a...

    If the ring is not damaged leave it alone. The sensor in your pic is slightly different than the ones I have changed in the past, but on those the gap was .1-.2 mm. Measure the gap before disturbing...

    Since the OP stated reliability was important along with performance and accuracy a Makino D800Z ought to make the short list.

    Iíve seen the cooling passages in motors get gunked up so itís worth looking at.

    Rungs 290 and 315 of the ladder image you linked are pretty basic comparison checks that set R6436 to 0 or 1 depending on the results of comparison. You will need to figure out what data R8400 and...

    The position display of the control would show .120 at the second hole and .240 at the third hole. This seems to me to be hard to overlook and a powerful clue in figuring out what is going on.

    Those max numbers you are posting are just what can accommodate in the toolchanger without crunching something. They donít mean that you can effectively cut with a tool of those dimensions.
