    Haas Super Mini Mill - Drowning in Way Oil

    We have a VF2 that has had this problem once in its life. If a similar system is used in the mini-mill you can try our fix. The separator internally gets clogged with contaminants and old oil so pull that plate off and clean it out (be prepared for a nice smell). Be careful with the plate as...

    Fadal 4020 Wall Finish Problem

    We checked the run-out as well we used the draw bar pressure tester to make sure tools are being held in adequately. I believe we had 1400lbs in that regards. Is there something we may be missing here you reckon? Thank you!

    Fadal 4020 Wall Finish Problem

    Seems like the consensus is we really need to look more towards the X-axis here! Appreciate the input!

    Fadal 4020 Wall Finish Problem

    You may be on to something here as well. In the Fadal machines the X-axis motor cable moves with the table so it sees a fair bit of wear-and-tear. We are going through the Z-axis gibs and then may inspect this. We should put an indicator on the X-axis ballscrew and feed Y-axis and observe to...

    Fadal 4020 Wall Finish Problem

    This is a suspicion we have arrived at as well. We are checking and adjust the gibs on the head right now. Right off the hop I could get the head to move the indicator .001" quite easily along a Y face (so moving the X-direction on the head). We thought that X-axis may be oscillating but...

    Fadal 4020 Wall Finish Problem

    Hello All. Have had some great info come from this forum over the years and I think everyone appreciates the help that is still available here. One of our 3-axis machines is an old 4020 Fadal which is something that is becoming harder and harder to receive support for. Anyhow, we have run...

    Fadal Drawbar & Piston Interference Issue

    This is good to know! We will definitely refrain from doing this from now on :o

    Fadal Drawbar & Piston Interference Issue

    Keep your stick on the ice... :bowdown: We just shimmed the piston plate assembly up just over .010 and its ran fine all week. I honestly think we were lucky prior to this that there was enough particulate (whoever owned this machine prior to us never cleaned anything, even when performing...

    Fadal Drawbar & Piston Interference Issue

    Yeah, it definitely still has a bit of a whir to it at certain RPM's but you can talk over the machine at 8k rpm standing beside it... so its probably no louder than the average old Fadali out there. While we had it apart, I noticed our Hi gear idler bearing has a ton of play and the actuator...

    Fadal Drawbar & Piston Interference Issue

    Fair enough :) We have been doing so all week with no issue. We did run into a learning experience with the belts. After the change and we were back running the spindle sounded excessively loud and rumbly. After some research our issue was seemingly years of old crud on the pulley's. We...

    Fadal Drawbar & Piston Interference Issue

    Thanks for the reply Del, had a quick look at it again this morning, when there is a tool in the spindle there is approximately a 1/4" gap, but with no tool it is extremely close. We tested that piston valve and cleaned the brass stone, and all of that seems to functioning just as you say it...

    Fadal Drawbar & Piston Interference Issue

    Hello All! :) The one and only Fadal 4020 we own has presented an issue that may or may not be our fault, hopefully someone can tell us, haha. Anyhow, We had to replace the belts on our Hi/Lo 4020 which was a fairly straight forward procedure, we removed the upper bridge, the two belt guides...

    Haas VF2 - Spindle Sound

    Right right, after consistent running its just slightly warm, felt up inside the taper. The machine has a 002020 warm-up program in it which looks like a factory program, we have run that both days on start-up, after that program the spindle is a bit warm, maybe a bit warmer than when its...

    Haas VF2 - Spindle Sound

    Thanks for the tip! Had the machine running this evening, just went down into the shop and ran it at 1krpm for about 15 minutes after completely cleaning the snout. Afterwards there were indeed a few hanging drips collected on the snout. We havent run the machine long enough to refill the...

    Haas VF2 - Spindle Sound

    Hi all, This thread is more of a sanity check as we have just recently acquired a Haas VF2. This machine is immaculate and only has ~2500 hours on it but I have managed to work myself up to the conclusion that there is a problem with the spindle. We just ran it yesterday for the first time...

    Fadal 4020 Y-axis Shudder - Bearings?

    Hi Everyone, we get our new resolver in tomorrow, so we are going to swap that out on Y and tune the axis as that has been recommended to us. Noticed something that I am just a bit curious about, maybe someone on here can chime in about. In the attached picture there are our three axis cards...

    Fadal 4020 Y-axis Shudder - Bearings?

    Hi again! We tested the resolver today by looking for voltage at its lead into Y-axis board in the side case. Both X and Z show ~1.5VAC where the Y-axis shows nothing. Checked for continuity to the resolver on the Y-axis servo and the harness seems fine, so we are assuming the resolver is the...

    Fadal 4020 Y-axis Shudder - Bearings?

    Thanks for the input guys! I found a doc posted by FADALCNC regarding the resolver testing, replacement also looks simple enough. https://www.fadalcnc.com/media/pdf/How_To_Test_Resolvers.pdf Our question to these two potential issue's is if we remove the servo to either clean the tach or...

    Fadal 4020 Y-axis Shudder - Bearings?

    Hi Everyone, took a quick image here, might be hard to see but it shows the faceting that we got when cutting. After looking around the various threads on here and other forums, seemingly this problem is typically not caused by bearings/slides, but from the tach or related items in the axis...

    Fadal 4020 Y-axis Shudder - Bearings?

    Hi Everyone, back again :) :) We are having a new issue with our 4020 which I am sure will be obvious to someone who has experience with Fadal's, which is not us :) Last week we ran a batch of 200 parts flawlessly, then the machine sat for a week. Today I ran the machine to whip up a quick...
