UPDATE

Haas replaced the spindle. The Haas tech agreed that the taper was messed up. You could take a toolholder with no pull stud in it, put it in the taper, and feel "shake" pushing back and...

My HFO is sending out a tech to look at it. They seem to be in agreement that something is not right here. I will update when I hear more.

My HFO seems to be pretty decent overall. I certainly will not let this go. My facility has 4 Haas machines and 3 run great. I really like the DT but this is bull. I do feel confident that has...

We blued up about a half a dozen holders. All with the same result. Also, the holders we blued were different brand holders as well. I didnt want to take a chance with a bad batch from one...

Go with 10K. I run 1" insert endmills at 12K in aluminum all day. I do believe however that it is nothing but a parameter and can be purchased later. Your HFO may be able to better answer this.

Hi All,

I need a sanity check. I have a 2018 DT-2 Mill with a 20,000 RPM Spindle. We use it mostly for endmills and drills under 0.125" in aluminum. Tolerances are not too tight on the parts...

Thanks all for the info

All milling with tools less than 0.250" dia. All aluminum. 30" long part.

Does anyone know the maximum part weight that can be placed on a HRT-210 rotary table? The table will be mounted in the vertical position and the part will be supported by a tail stock. Rotary axis...

I had the same problem that almost resulted in a crash. I went to get another mic and by the time i was finished QC the part (took a bit to find the micrometer), it was back on the home screen and I...

2" pipe = big wrench with usually a 2 or 3 foot pipe on the handle. Great way to get something either really tight or busted. Hey, you have a machine shop. If you bust it make a new one :)

I don't have a boss... I am the boss! This is good for me.

BTW,

Most of the stuff that I do is with small tools and quite a few tool changes. 0 to 6000 rpm to 0. Not a lot of tapping though. cycle per tool often is 20 seconds. then stop and next...

Thanks for the tips guys. I replaced the 320 ps in september so I pretty much ruled that out. Talked to a customer of mine that is very familiar with servo systems and he also said that my problem...

More Info: I can reproduce the problem by running up to max RPM and then hitting stop and going to max RPM again as soon as the spindle stops. Usually takes 3 or 4 times of doing that but sure...

I have a strange error that showed up 2 times for no reason recently. 123 spindle drive fault. Once on start up and once on accel to full RPM several weeks later. After I cleared the error the...

I also do not want to see Haas got to hell in a hand basket but it seems that this is the way that they are going. I see more and more complaints about things that should not be an issue on these...

And the USA is a BIG MESS Why? I just hope Haas is not lumped into the to the "too big to fail" group. Then we will be forever stuck in the obviously increasing amount of cheapening of Haas...

I have a Pneumatic 5C Unit made by Atlas. It has thru bore capability and is dead length on closing style as well. Everything to operate it is also up front so you just bolt it on and hook up the...

I confirmed a price on the PS. It is $1350 with a core. The easy thing for me to do is replace the PS but I am still at a loss as to why it works after putting it in the refrigerator. Is there...

I dont think that they are being malicious, just stupid. I think that it may be an Arizona thing because I run into the same thing everywhere from Walmart to local suppliers. Just part of the...

I am still having problems. Once I get the machine to powerup without any PS errors (by putting the PS in the fridge for 10 minutes) It can run for hours on end taking fairly heavy cuts as well. ...

Just a random question. You wouldn't happen to know why putting the PS in the freezer for 10 minutes makes it run again?

Just Curious

Thanks man, you may have just prevented a suicide!!!

As far as the load goes. I have one leg showing 31 amps of load and the other at 12 amps. This combined with the power (which the power...

I have a problem with my 320v power supply. I am getting error A on the PS that translates to phase AC fault. I am running the machine on single phase. The does this off and on. I disconnect the...

I would cut the RPM on all drilling down about 50% and take much larger pecks. If possible do not peck with 304. T1 = no peck, T2 = 0.250 peck. Pecking and dwelling in 304 is a sure fire way to...

With all due respect, that machine would give me a never ending anxiety attack from the huge swaths of red paint!

I have been there.

You will need to have High Speed Machining option on for this kind of feed rate. Using arcs (G02 G03) is much faster than using point to point even with the HSM option on. It means less blocks of...
