Machine grounding

I’m trying to fill out the forms to get a tech out to set up the machine and I’m just seeing some requirements that I don’t meet but can be fixed if necessary.

Haas says the ground needs to be the same size as the incoming wires. Right as it sits I have three #3 for input and the ground wire is #6.
Is that not good?

If not can someone explain why the ground and line need to be the same size?

And layman’s term what do you consider a dedicated ground?

I have 2 hots and a neutral to my sub panel at shop and then from there to phase perfect to disconnect to machine it’s grounded. So I’m grounded back to neutral of main box and shop building. That sounds good to me but I’m no electrician and everyone I’ve talked to are not familiar with phase perfect or cnc machines and they are not comfortable working on it.
Does any of that sound wrong?

I'm looking for suggestions on manufacturers/tooling options for a st20y BMT65 turret. Lyndex Nikkon has been recommended. I know little to nothing of live tool holders. Looking for the best clearance possible as we will initially being doing a good bit of smaller parts. Open to suggestions on where I can learn more and who I need to talk to. Thanks!

Vf2 probing and work offsets

Hey guys. So I've got thrown in the deep end here a bit at my new job. Out milling guy no longer works here and I'm left trying to figure out how to run our Haas vf2. I have a little milling experience on a Hurco at an old job.

This machine has a tool probe and work probe. The work probe is pretty self explanatory, I touch and it zeroes that axis. I'm a little confused on the tool probe though. It's mounted on the table, and when I touch off it does...something, but how does it relate to the work zero? I don't know where the tool probe zero is, do I? Does this make any sense?

Spindle break In

Does haas break in the spindle at the factory or do I have to do it?

The tech is coming back tomorrow to mount the rotary and to set up the probe and I asked him today before leaving what was left and he said you could actually make a cut “I’m not going to until he’s finished” but I was still wondering if a break in needed to be performed other than warm up.

So what say y’all?

Probe - tool length out of range

I tried to probe the first ever tool in my mill and I got “Tool length out of range” and I can’t find anything in the manual or online of what is causing this. I set my approximate tool length to 4.625, well under the max tool length of machine. Has anyone else had this happen to them?

Also when I first powered it up after the tech finished and left, and the last operation was on the screen and the first line said “Complete probe calibration”. I’m guessing this right and it’s just the last thing he did or is it saying you need to complete the calibration?

Also, I knew I was going to lose table with the setter and the 4th but didn’t realize I was going to lose as much. The tool probe is inset enough to max out tool diameter by more than 2x around a 12 or 14” diameter tool and that’s giving it plenty of room to clear the setter when measuring diameter. That is not an exaggeration. My probe is mounted to the left side of table bc of 4th. Also the hrc210 is installed about 4” from the edge of the tables. Once you add on for the chuck and mounting plate that a lot of used up table. He said he was giving room so the rotary didn’t hit the window and I took his word for it but after he left I jogged over and there is plenty of room.

So I think I could get at least 10 more inches of tables by moving those two option further out. Is there something I’m not seeing that is keeping me from doing that?

Here’s a couple picture.

Runout on toolholders..(not spindle).. drawbar?..bellville washers. how to diagnose?

October 22, 2020, 3:42 pm

Hi everyone,
98 VF4.
My kid is trying to understand how someone might diagnose runout with toolholders in the spindle. We've done the taper checks (clean and and bluing test) w/ tool holders. Bought quality tool holders. But.. we only have basic ebay and amazon cheapy pullstuds.

He has checked the spindle run out.. it's max 2 tens. everytime.
He looks up in the spindle cone and we snapped pics w/ the bore-scope. Link below to gdrive w/ pics.
spindle - Google Drive

As he keeps trying combinations of his newer quality toolholders (kennemetal, Regofix, types) with his pullstuds it changes. sometimes a thou.. sometimes up to 3 or 4 thou even. (at the actual cutter shaft and insert hole ). He determins the best side (180) and marks the polarity for each toolholder to east dog.

I just ordered some quality Maritool pull studs. But he's seen posts on drawbar and bellville washers? but I have not had any time to research either. If not this... then where does he go next?

We do not have a drawbar tester... but Didn't I see some type of device you pop in the spindle as a standard or something?

thanks folks.
GC.

If I order my st20y with 24 (half index?) station turret, am I able to use the dual output live tool holders to have potentially 2-4 (2 main, 2 sub) holders per live tool drive?

Link to some holders for reference.

RADIAL SINGLE-SIDE TWIN HEAD DRIVEN TOOL IN Y-AXIS – MD Tooling – Precision Live & Static Tooling
AXIAL SINGLE SIDE TWIN HEAD DRIVEN TOOL IN Y – MD Tooling – Precision Live & Static Tooling

Is this something that is called via a tool number and thus easily used with cam programs such as fusion easy?

Lathe Spindle displacement ?

2007 SL 10.
New to me, and has very low hours, consider it new! Seriously - I don't think it has ten hours of spindle on time. It is that clean, I need to look but trust me - its mint!

We came by this machine when the owner lightly crashed it and decided there is more to machining than he thought, PHD with deep pockets.

People with GEDs can run them, how hard can it be?

So seriously... I have never run a Haas lathe and I am struggling with a second opp with bored soft jaws to get the parts true. But a lathe is a lathe and an easily deflected spindle is bad - I can't do this on our Hardinge or Monarch.

Cut to the end - I set a 0.0001" Indicator on the tool post, touching side of chuck. With a 1.250" steel bar stock 8" from chuck jaw face.
Palm of hand on end, elbow on hip I can deflect the chuck 0.0004" pull back 0.0002". Total of 0.0006" agreed?

Using a bathroom scale against the concrete wall I can get just about 80 lbs pushing. No idea on pull but I imagine it less.

Tell me this is wrong please. We are contacting Haas for a service call. Any experience to share?

I have a 2008 VF2, needs vector drive, in no rush so im shopping for deals
are the drives backward compatible, can i use an older drive in place of a newer one?
I talked with a guy stripping a 2005 mdc500 with a older style 20/15drive, my 2008 is one drive generation newer 20HP.
can I plop his into my vf2 and run safely? Haas does not change much between generations...
his is the white style on far right of photo(4), mine is the one next to it(3).

HAAS - Tool Type Macro

October 24, 2020, 3:39 pm

On haas tool offset page you can tell the control what type of tool is in the spindle. Drill, Tap, End Mill, etc.

There are macro variables to this column. #50001 - #50200 but they're read only.

I just want to confirm that you can't load that info from a program.

I'm sure there is a reason they made this read only but it seems silly. It would be nice to load all that info from the program. You can tell it approximate diameter, flutes, etc. but not type? Lame.

Haas Alarm 161 & 991

I receive two alarms at the end of milling: Alarms 161-164 AXIS DRIVE FAULT and Alarm 991 AMPLIFIER OVER TEMPERATURE

The temperature of the shop is 60 degrees, and I was running my first program of the day (so machine had been off). So I can't imagine the amplifier was over temperature. I could touch all 3 amplifiers with my hand and none felt warm.

So Haas states that if these two alarms are triggered, to check the cooling fan (Servo Amplifier - How it Works and Troubleshooting Guide | Customer Resource Center). The fan appears to be running fine; moving a great volume of air. But what confused me is that the Haas troubleshooting guide recommended checking the voltage to the fan:

"If the fan does not operate correctly, measure the voltage it receives. Disconnect the cable from the cooling fan. Measure the voltage between the leads of the cable. The correct voltage 120 VAC.

If the cable has the correct voltage, the cooling fan is defective.
If the cable does not have the correct voltage, go to diy.haascnc.com to troubleshoot the Power Supply PCB."

Haas says that if the cable has the correct voltage, then the fan is defective. The cable showed to supply 119v. Can a fan be defective even though it seems to be running fine? Has anyone experienced this?

Thanks.

2019 machine vf3 hard tool changes from time to time

I keep my pull studs greased
I keep my machine and taper extremely clean.
I don't leave tools in at night.
Air system is over kill for one machine, pressure doesn't move when tool change happens
However regardless of what I do from time to time a tool change will have a loud bang.

It's completely random and doesn't happen everyday day. I would say every few days.

I though at first it was a operation (drilling), it also did it after hogging out some alum.

All my tool holders are Maritool.

If I've missed something, ask please.

Wtf didn't I do? Smtc no Tool pocket menu in controller???

My controller seems to have lost its tool/pocket menu. OR im totally stupid. Pick one!
2008 vf2 w/ 24smtc

Fire up machine. Hit current command button. Page up
Through all the menus. It's not there!!
I've seen the menu before. But
Cannot find it anymore.(don't know how I got there the first time)

In current command and page up I get
Current program
Tool group
Tool max % limit%
Tool life
Maintenance macros
Power on time
Current commands


So I bought this machine and removed the changer. Stuffed it into a garage. Took me a while to re install the changer. I've have changed the tool changer setting between 5(smtc) and 8 (manual) change a few times to get a job or 2 through before install-alignment was complete.

I've gotten it all up and running now and went to finally load up the tool changer for a program and cannot find the menu!!!

Tool changer settingnis back at 5. What am I doing wrong!?!?!??
I cannot imagine I screwed or up by switching to manual change.

If I hit atc back/forward it goes through the motions and says whatever tool it thinks it loaded (it's empty right now)

Ideas??

2009 cold fire 2 not remembering tool pockets

Is this just a battery issue when the tool table deletes a tool pocket from a tool? Setting up a program for 4 hours with 11 tools is a real chore. Machine will randomly reassign tool pockets as setting preset pockets to zero in the tool table. I am setting the tool pockets manually from the tool table (MDI/offset). Precalling the tool from a 40 tool twin arm and putting the M01 before the precall. Started happening earlier this week.

Bought a 2008 OM2 mill

Hi everyone. Long time member but haven't posted in the past. I have had a 2002 Mini Mill for the last 3 years and I have loved having it. It's has been flawless as far as performance and reliability. I've been machining only aluminum and plastics on it. I have been struggling with the slow 6k rpm spindle as often times I have orders for parts that have features with as small as .010" radius and needless to say the 6k spindle has been limiting. I came across a Haas OM2 with 30k rpm spindle and a HRT110 4th axis. Came with 23 tool holders, most of them are original haas holders and the remaining are Techniks. The spindle was replaced by Haas in 2018 and the new spindle has about 500 hours on it. It was also thoroughly checked and calibrated a month ago.
I am not expecting the thing to be able to take any heavy cuts but in general I wanted to see what others' experience has been running one of these and if there are any pointers or tips.

4th axis

I am cutting a feed screw on a Haas vf4 with an hrt 210. I have managed to get through them no problem, but with a few issues still. When I press the feed hold button the x y z a axes do not come to a complete stop.. It literally takes a few seconds slowly coming to a stop. The other issue is when it comes to the start and end of the screw the acceleration deceleration either slows right down or goes extremely fast. This causes it to almost jump witch then alarms out the machine. Anyone have this issue I believe it is all parameters that need changed. I got the parameters from a older vf2 in our shop this worked but I believe that the vf4 has a newer controller so a couple of the parameters need to be changed I just can't find anything on it on line or on the haas website.

Block Processing Speed On Older Controls? 2005 MiniMill

November 5, 2020, 4:31 pm

So I've been trying to do some single point forming work on some 3d prototypes. This of course means that since I'm not removing material, I should be able to run higher feeds rates without worrying about tool breakage :p

However, my 2005 Haas Mini Mill seems to start stuttering at around 10 blocks per second. Is this really the max processing speed of a 2005 generation control? The feedrate at this processing speed is about 20ipm, MUCH slower than I want to run.

I've gone through the settings, and everything seems be factory stock. Corner rounding is set to 0.025, finish is 'medium', etc. G103 (lookahead... if it exists?) is set to unlimited....or I at least call G103 without a parameter. If I do call a parameter with G103, I get a divide by zero error.

If I want to set my smoothing to .1 in CAM (with a regular tolerance of .0001), then I can of course up the feed rate a little bit, but it's still limited to around 10 blocks per second.... and of course a smoothing tolerance of .1 is an absolute joke.

In a few manuals from its era, Haas still claims 1000 blocks per second (found in a VF series 2004 manual).

Ultimately, if a new machine can process this code at a true 1000bps, or hell, 500bps, then I won't have an issue upgrading. I just want to be sure I don't throw $120k at something that won't solve my problem.

I contact my local HFO inquiring about the processing speeds of 2005 controls, but they had no idea (unsurprisingly).

So, at last, I have wound up here to see if anyone has any ideas... Thanks!
