I think it's a T-32 control. I have never seen a QT28N with a T-2.

The tools from a ST20 ATC will not fit anything but that machine and a QT10N ATC/MC.

Please unbolt the C-shaped tool holders from the tool chain. Those gems never come up for sale.

I gotta ask, why scrap the machine if everything works on it?

I work for an aerospace OEM company in the Research and Development department. We make both research quality parts and development quality parts. There is a huge difference between the two even if...

No. M11 activates quill and body as a unit for advance and retract when commanding M31 and M32. M10 disengages the body from the quill when commanding M31 and M32.

You need to type in M11 and then type in M31. M11 activates the tailstock quill and the body.

M10 is active right now and that means M31 will just extend the quill.

The OP is talking about a CNC lathe with a VFD--not a manual lathe.

I installed a soft start on my 15 hp manual turret lathe so the inrush wouldn't kick out my CNC lathe if I was using them at...

My lathes see the biggest amp draw upon starting the spindle. Actual amp draw during heavy cutting is still lower than when the spindle ramps up.

Check your spindle acceleration parameters. ...

The only way to toggle off the cutter comp is to completely clear out the cutter diameter from the tool data page or you accidentally edited the program to be Line Center instead of Line Left. ...

Center of the endmill needs to be X zero. Same as you would set a drill bit.

Here's my cheat sheet for milling a hex on the Mazak.

When using polar coordinates (green numbers), program to the corners of the hex. Take the radius value of your flat (1.5" / 2 = .75") and multiply it by 1.154 = .8655" to get the dimension from the...

Sounds like it is a positive air purge for the turret to keep out the coolant. Newer Mazaks also have a positive air purge for the spindle.

The chuck needs to be in a clamped state before the spindle will start.

I believe he is talking about when the tool is backturning the faces on the finish pass. Finishing from smallest diameter to largest diameter with BAR OUT process.

Yes .

It would take a LOT of extra programming to do it that way and is really not needed for 99% of the things I have come across and I've been running Mazatrol for 24 years now.

Sounds like your...

The holder types in my older machine are listed as 1-4. Yours is the next generation control after my T-3 so not sure this will apply or not. Basically the different holder types just call up...

Milling the flats as you described in your earlier post with a 90° head is not possible with just a C-axis. You would need a machine with a Y-axis.

The only practical way to mill flats like that...

Sounds like the spindle VFD might have died.

Make sure the spindle is stopped and you do not have a part in the chuck when you flip that switch. The chuck jaws will move to the opposite position when you flip the switch.

If it was me, I would put in a disconnect after the breaker.

In my experience, circuit breakers in a breaker panel do not like it when there is a heavy load on the circuit when you turn on the...

Got it. For this feature which is .25" above and below centerline, use XY coordinates. To do this, you push the XY soft key and then anything you enter will be yellow indicating you are in XY mode....

In my example, the machine will make a cut and leave 1/2 of the bar from center. It will comp the endmill as shown in the graphics.

I can't help you anymore without a sketch of what you are...

X.7 is the length from centerline where the cut starts and then ends. You need to put in angle 0 to start and angle 180 for finish. If you look at the graphics, you will see what I'm talking about....
