    I have a 3 jaw and 4 jaw for general work. I don't do a lot of plastic, or thin-walled stuff that distorts enough to warrant a 6-jaw. The four jaw is extremely flexible for job-shop stuff in very...

    Remove those plugs and try indexing the turret one position at a time. On the later vertical turret machines like mine, you have two plugs like that, and you have to index the turret to access each...

    I concur. Page 3-29 looks like just the bottom half of the coupling.
    The upper half must have been removed with the turret for that photo.

    The coupling must bolt to the turret just like the...

    You can use the baffles as a skimmer, kind of like the separating tank on your mill.

    You cut a notch in the top of each baffle extending just below the nominal coolant level in the tank. Just...

    I put it all on every line like you did.

    Try the 3 grooving process method I showed, I think you'll be happy with it.

    On the G3 issue, I'm no wizard in manual process on our mazatrol machines, but I'm fairly savvy with g-code on the...

    Pete, you can do this with grooving process... No need to punch in all that manual code.

    Make two grooving processes.
    First, you make a shallow type 1 groove just to get your chamfer or radius...

    *edit* I hadn't read anything but the first post when I typed this... I'll leave it as-is just in case it's of any help *edit*

    That's probably the only way to get a dwell with the drill cycle.

    It will take several lines of manual process (lots of keypad time) to do a peck cycle... If you think you'll use it again, copy...

    I do this too, in deeper holes (longer chips).
    For a shallow tap operation I can go R = 0.2 but for the deeper holes I'll go as much as R = 1.0

    Do you have air-blast? It actually helps to...

    There are a few ways to do it. A quick easy way would look like this:

    1) EDG process to face the saw-cut end.
    2) BAR_OUT where End X is your finish diameter.

    The control should be able to accept drip feed from a computer (without using the BTR) if it has a RS232 port.

    This is the Grooving section from the T2 Manual.
    Hopefully enough of this applies to the T1 control that you can get the hang of grooving.

    A good way you can generally trace down an air-leak in a tight space is to put a piece of rubber tubing near your ear. You can probe around and fish the other end of the tubing into tight places. ...

    On my QT-10, there's a big 8" dia rubber wiper that keeps chips, coolant and junk out of the cervic-coupling behind the turret.
    Your QT-8 probably has a similar wiper. I believe it is part # 51...

    I start all my Mazatrol programs with process 1: M-Code M8

    In my experience (Mazatrol T2 control) you won't get coolant until the end of the sequence where the M8 is issued.

    BT's are longer, but that length is in the flange itself. With a compatible pull-stud, CAT and BT will both go into the same BT spindle, but cannot be mixed because the tool changer will crash. ...

    Also check the angle on the pull-studs (retention knobs). The angle under the knob is what matters and they vary between different machine tool makers. Some are 90°, some 60° and some are 45°.
