It was the belt cogging as expected. At the time, I was inexperienced and reluctant to remove the belt because the manual showed adjusting proper tension using a dial indicator to a high degree of...

Thank you for your reply.

The machine is a Hardinge T42 (not the "super-precision", and therefore no temp comp) with Fanuc 18T control.

The Hardinge T42SP accomplishes growth compensation with...

Gentlemen,

I start up my machine cold at around 16 degrees Celsius and over the course of eight hours, the temperature of my shop (and the machine) rises to 23C. Needless to say, this results in...

Have any of you used the feed-rate knob to adjust for a material with lower machinability rather than adjusting in the program itself? OR, configured your program to adjust only SFM depending on what...

I know this is an old thread, but asking about macros other than deep drilling seemed appropriate here given the title. My 1997 Conquest T42 with 18TB control has only canned routines for turning...

Since my post, I contacted Bob Allington at Hardinge who look in their manuals, saw the code, and plugged this code into one of their T42's with subspindle. He got the same result! Z is modified, but...

I tried the example for transferring a part from the sub-spindle to the main spindle as shown in the Hardinge Conquest T42 Programmer's on page 16-19. In this example, it uses the G10 P0 command to...

Agreed. G10 P0 is a generic write parameter function, but it usually takes an L argument as well.

I tried with L2, and it correctly wrote to the Y register but not in he workshift file. Instead it...

Yes, on my Hardinge T42 there is an additional "Workshift" offset for each of the axes in the workshift offsets page (shown below) that is different from G53, and G54 through G59. The so-called "5024...

Hello everyone,

Thought I would chime in here and tell everyone that I have a Conquest T42 too. As a matter of fact, I bought it a year ago and have been "restoring" it. Had to take the...

Hello everyone,

Thought I would chime in here and tell everyone that I have a Conquest T42 too. As a matter of fact, I bought it a year ago and have been "restoring" it. Had to take the...

Sorry guys, this is kind of a noob question, but in the Hardinge Conquest T42 Programmer's manual under section 16, page 16-19 it shows an example of transferring a part from the sub-spindle to the...

According to your previous and recent readings, your machine is balanced to 0.69% when idle, and to 0.27% (yes, each less than 1%) when loaded with 80% spindle?

Columns A, B, C, D...

Thanks for those readings. Your readings aren't far from mine, but I think I'm drawing more because my RPC doesn't have PF caps. Not sure this is important for overall balance, or just for...

Mine is a Fluke 289. I operated with a Radio Shack Multimeter for nearly 30 years, and had many models including the three (of ten) benchtop meters I photographed earlier. I also had this Fluke...

So, yesterday was a bust because of kids activities, but I managed to squeeze in a little test.

IT'S TOTALLY PRELIMINARY. I was just playing with my new clamp meter, and I decided to try out my...

Not a problem. I love the feedback so far, and I'm glad to have you watching. Sometimes it really helps to talk through one's problems.

Now armed with my clamp meter, I will really start...

I understand now why you only provided one reading. Your CNC reads the same open or closed, so no need to provide two readings.

Though whereas your CNC has no load difference between the open and...

This morning, the temp outside was -2. Opened the garage door from a balmy 17 degree C shop, so I knew the oil was not an issue. In retrospect, I don't think oil temp was ever the issue. I thought it...

General Disarray,

Thank you for measuring all that for me. Yours are all within 2% during steady state, and that explains the small imbalance in the hydraulics. It gives me a target to shoot for....

So a few things... and I apologize for how lengthy this is, but I've looked at a lot of stuff these past couple of days.


Jim, I took your advice and looked at the cabling. I have 30ft of #6 from...

Hey Jim, can I bend your ear again?

For a while, I thought I had solved it... and in theory, I still have - but now when I have the machine running on all cylinders with the primary and secondary...

I like the switch idea, but I would want it done automatically somehow... for example using a voltage sensor on each leg that, when the voltage swings too low, closes a NO relay that engages another...

I figured it out. I should have started with what you said, but I don't think I would have made the connection anyway until after I went through this process.

Started by disconnecting the motor...

Another interesting development:

I was fed up with the clamp meter results and decided to use some old Micronta DMMs inline with each phase instead. Each meter was set in current-reading mode (up...

Jim,

I kept editing my post while you were responding, but I think you and I have come to the same conclusion - the relay on the edge, possibly caused by temperature as I've edited below, but also...

Now I understand. Your machine is quite different than mine. I'm running a Conquest T42, with Fanuc 18-TB control. Your machine appears to be a Conquest 42.

The schematic in my machine shows...

I cannot find MCDF.S in the DIAGS or LADDER. What address is this bit located at? I'd like to watch it in the diag screen as the collet opens.


Torin...

Great idea, Jim. I'll poke around back there and see if the switch is faulty, loose, etc. Will update here after I've had a chance to look at it.


Torin...

Can anyone think of a reason why opening the main collet closer for more than a few (like 10 or so) seconds would cause a hydraulic overload and trip the breaker?

It only happens when the main...
