Haas control shift offset

$
0
0
howdy

for the past 8 years ive only worked on DAEWOO and DOOSAN machines with FANUC controls of course. I recently took a new job, and they have all HAAS. When I used the FANUC there was G54, G55, G56 etc. Above my G54 setting was a "shift offset 000" where if I wanted to offset my Y +.010 all I had to do was put .010 into the y coordinate instead of adding +.010 into the G54 and changing my TRUE origin. On the HAAS I see there are G54 G55 and so on, but also a G52. do I have to change my actual G54? is there a world coordinate offset that I can make incremental offsets instead?

Doesn't Haas have a setting so you never overload the spindle?

I thought the Haas control had a setting so that if the spindle load hits XXX%, you could have it shut down all movement. And that % was settable. Does it have anything like that? I can't find it, I only find tool life management.

Besides HAAS where can I get a 3 jaw chuck for a hrt 210

Hello.

I just want to know where a good place to buy one is. Haas is quoting almost 1600$. Are there cheaper options out there? Better? On this site I learned about orange vises and was thinking that maybe you could recommend a good chuck.


Thank you

TM1 power supply info

$

0
I have a Haas TM1 (2003) and would like to find out a bit concerning power supply. My facility is Delta 3 phase and the machine says it needs Wye power. If we wanted to run the machine on 3 phase I will need to get a transformer to reduce the high leg. Am I compromising the machine in terms of power if we run it with 1 phase 240v power? Either direction needs me to run new wires and add a separate circuit breaker so I am not concerned about that. Just curious if I am better suited getting the correct 3 phase power over running it 1 phase.

Thanks in advance.

Cheers,
Drew
ps-my electrician is very curious what the coils (resistors) on top of the machine are for?

Editing on haas control

im setting up a simple 2d contour with a WEAR offset. There are multiple "D3"'s in the code, but if I want to change em to D-any other number, how can I change the first one and make all the others change like it?

on fanuc control I could go to the first D call out, select it, go to EDIT and change it from BEFORE to AFTER and it would change all the D's that were matching the BEFORE offset, all at once...

sorry if I explained it crappy

HA5C woes

$

I have a VF2 with an HA5C indexer.
It seems the indexer is rotating in the wrong direction.
We have been using programs from our old VF1 with no problem.
Up until now, all the indexer parts were uniform radially and it didn't mater which way the indexer rotated.
Now we have a pile of scrap and are puzzled as to why.
Looking towards the collet, G0 A74. causes the indexer to rotate counter clock wise.
The program needs it to rotate clock wise for the part to be correct.
What could be wrong?

Pocket tool table error 941

$

I realize and understand that on a side mount tool changer, the tool in use and the pocket number will constantly be changing and not always match. Great.

ok, right now im only using tool numbers 2-17. I need to add in a few more tools, but every other tool number I call out is giving me this 941 alarm. So, I need to figure out how to get the table set up correctly. I have no larger tools actually in the machine, nor are any of the numbers in the table set for large tools. if I reset the whole table, I know ill have to set all my tools again, and that's fine. BUT I need to be able to use all 24 or 24+1 tools.....ideas?

now on the tools that are working correctly, I can see my tool number, and the pocket that its located in. On my spindle tool I see pocket zero, but on all the ones that aren't working when called up, thay also have zero in the pocket number...if that helps

im new here and its been a great tool so far on this forum

Alarms 117/118/126 Gear Fault - 1998 Haas VF-3

$

I had this posted in CNC machining when I noticed there is an entire section for Haas. Here we go.

Greetings to all of my fellow CNC compatriots,

This is my first posting. I've always looked on the site for advice to my problems, and just recently did it occur to me to join up and ask about the stuff that I come across. I work for a small, mold-making business, and of the many hats I have to wear, CNC repair guy is beginning to become one of them. I am 3 years in the industry, and with our company's resources, I've often had to teach myself as I go.

Right now, I am busting into a 1998 Haas VF-3 CNC machine that needs a lot of love. I am trying to repair a lot of issues with it using some tech support and a service manual, but I admittedly don't have a ton of experience when it comes to the guts of these machines. I'm hoping that you all can help with my current quandary. As of right now I'm stuck, and I'm only guessing at the problem.

Some time ago, our vf-3 wasn't shifting into high gear. This would happen on power up restarts or if we'd manually enter spindle speeds. I've taken off the solenoids and checked them for continuity, as well as manually activated them. They sound like they are getting air. The circuit breakers are functioning. The next step would be the gear box, but I'd rather hear from all of you before I do taking off the trans.

ALSO: During the current maintenance that I have been doing, it now has a new problem.

After I removed and checked the solenoids, I now get 126 Alarms. M41 and M42 will give me 126 alarms if I try to use them, and power up restarts have given me low or high gear faults depending on if I've looked at the solenoids with or without the air on.

The machine could at least tool when it was stuck in low gear. Now it can not function at all. I'd rather get both gears up and running. Any advice would be greatly appreciated. :willy_nilly:

skimming oil off coolant tank in lathe

Hi,
I pulled the coolant tank on my SL30 last night. I thought it's kind of interesting, the different amounts of oil on the different compartments. I skimmed the worst compartment last night and took the photo this morning when i got in.

Anyways, I'm wondering what the 'correct' way of skimming oil is for these types of machines. I don't really want to pull the tank out every night to skim off a days worth of oil... Once a week might be an option... I suppose if I let the coolant level get down low enough, the oil would flow under the dividers of the different compartments and I could skim it all at the access hole beside the pump, but I don't usually let my coolant get that low. And I'm not sure the oil would work it's way all to one end, the tank must be about 12 feet long!
Anybody have any good tricks to share to make this a bit easier?

Tool touch off between tool changes.

Howdy.

This is probably one of those "Read the manual" things. But how do I do it? Can I splice code into my CAM generated programs, can I have HSM works do it automatically? It would be great for the machine to stop if it figures out that the tap is broken rather than moving onto another tool.

Thank you so much.

Tool holders for Haas, New/Used, and which ones?

$

Hello everyone!

Hoping to have my machines up and running soon. Looking at the next progressive step and been eye balling used and new holders for them. My intent will be to use them to do some prototyping work, and from there hopefully run some small batches of parts to get me going. Flexibility on a budget is paramount. Since I have a few things in mind to make, i'm in a bind on how to distribute my holders, for example:

16 holders total:
(1) facemill
(2) drill chucks
(6) set screw style holders
(1) 3D taster
(6) collet style holders

This would allow me to keep a "general" set of useful tools loaded to get me going. I'm sure i'll buy a ton more, but for now just looking to get making a couple chips!
Any help would be appreciated.

Thanks!

VMC 40 taper spindle pulley removal?

hey guys, im building a from scratch mill, in the process of sourcing a spindle to use, and have found a couple Haas 40 tapers, they are from around 2001 with the shrink fit pulley. for my application I would want to remove the stock pulley and install a step pulley, probably two pulleys since step timing pulleys are close to non-existent. how does one safely remove the pulley from the spindle shaft? the pulley has a bunch of tapped hole so im assuming that there is a special puller to bolt on and then with some heat you pull it off. thanks for any help

Bijur lube diagnosis: 1998 VF-3

$

Hey guys,

I'm in the process of cleaning up and repairing a 1998 VF-3, and I am trying to address some problems with the lube system.

For some time, lube would not circulate properly in the system, and it kept getting "low lube low pressure" alarms.

I've been able to manually pump the system, and it will make the alarm go away. While pressured, the ways are getting lubed and my lines are filling with oil, but this pressure will slowly diminish down to zero even with the spindle in motion (slowly as in hours).

I have taken apart the stone filter and cleaned out the lines to and from the actual bearing valve. When the system was removed and the spindle turned on, I was able to see a very slow rotation from the pump motor.

I read a posting from Sagespecialized that sounded similar to this, but I am worried that it is the pump itself; not just clogged or leaky lines. I'm looking to see if someone has had past experience with these kind of issues, and that they might point me in the right direction before I go down a rabbit hole.

My next step that I was planning on doing was to make sure I have correct voltage with the spindle on.

Any help is appreciated.

Haas Gear Box Shifting Problem

$

Hi Everyone.....Ive been battling a shifting issue in our 2002 VF2 for some time now. I have replaced the solenoids, rebuilt the gear box, installed a new plunger assembly, etc.....pretty much everything I could think of and I still cannot get it to shift from low to high.....high to low is no problem because of gravity. I gave up awhile back and just manually popped it into high gear and disabled gear changing. I ran it like that for about 6 months but just recently the spindle motor bearings started to go bad so I just pulled the motor out and sent it off to a local shop to have new bearings installed. I figured while the motor was out I would take another stab at this gear box issue.

I guess my main question is for anyone with experience tearing down these gearboxes, do you know if the gear change shaft should be able to move up and down freely by hand without a burst of air? I can easily move it from high gear to low gear by hand because gravity is on its side but when trying to push it up from low gear to high gear I cannot do it by hand...I have to take a mallet or something and use a little force. This leads me to believe the shaft might be slightly bent or might have burrs or something. Any input is appreciated. Ill see if I can post a video or something.

Adding tsc to a vf5

I have a 2013 vf5 I am looking to add thru spindle coolant too. Haas says it is prepped for it but will not tell me if i can hook it up and go. Located a 1000psi setup used and dont know if it is a good deal or not. It all depends on what is needed if anything to the machine and control(haas code)? Any ideas?

Setting tools on SL20 without toolsetter

$

Good Morning,

historically I have posted on here about the toolsetter fault I have, having now established that the tool setter is faulty and now waiting for where I work to sort out a new one I still need to get work out. I am now getting my head around setting the tools the old fashioned way by touching on each tool in x and z, I have taken the value out of the G54 workshift setting and using the z measure function to establish my z zero. Am I right in thinking that I need to measure the face of every job now whilst keeping the G54 value at zero or is it possible to leave my geometry values as they are and put either a minus or positive value in for the G54. My first instinct tells me that I have to touch on each tool if the length of the workpiece changes.

Thanks

Nigel
