Honest Question: Do modern CNC machines still need battery storage for settings?
My 2 O&H lathes with 18t's will give me a low battery alarm. My Doosan does not! After a couple dead batteries and the associated bs that comes with that, I purchased a kit from these guys: https://www.corednc.com/ Life with the Doosan is much better now!- chip_maker

Ballbar test results - how to interpret?
If everything else checks out, I'm wondering if it could be a servo tuning issue?- chip_maker

I would check drawbar tension on both machines, also check spindle taper/toolholder contact.- chip_maker

I have a 2023 DNM5700. Is the coolant/chip management really supposed to be this terrible?
I also recently installed a new DNM5700. Seeing this makes me glad I sprung for the filtering conveyor (LNS Turbo MH140). That being said I find the Doosan to be MILES ahead of the Haas for chip management. Agree with the other posters, you need to make bigger chips, or replace your current...- chip_maker

2.375in hole in 17-4
Too bad you don't have a horizontal. Looks like a nice part for one.- chip_maker

Strange axis feeding issue
I'm no Fanuc expert by any means, but I think the 2 encoders "compare notes" and will throw an alarm if they're on different pages. How's the other pulley and belt look? I also don't know if removing the encoder will disturb anything? it looks like it can be clocked?- chip_maker

Strange axis feeding issue
Looks like maybe an encoder issue. How is the encoder set up on this machine? Is it belt driven or hall affect sensors? I had a similar problem on one of my lathes that uses hall affect sensors. There was some congealed coolant or something on the rotating part. I cleaned it up good and that...- chip_maker

Okuma&Howa ACT 3 bar pulling problem
So it appears to be waiting for a signal from a non existant barfeeeder. Sorry I don't know how to address that. Hopefully someone else can help. Might be a setting or parameter that needs changing, but I have no experience with bar feeders.- chip_maker

May be another M code to allow for movement with the chuck open?- chip_maker

Are you positive M15 & M14 are chuck open & close?- chip_maker

Okuma&Howa ACT 3 bar pulling problem
1) You have to find the M codes to allow for motion with the spindle idle. On my ACT & HL machines it's M34. 2) You need to add a G98 in the N07 line or before it to put the machine in IPM feedrate mode. I use Royal pullers so I feed off of the part and not at X0. Here's a piece of one of my...- chip_maker

Does anyone make a quiet CNC Lathe
2 of my lathes have Nachi hydraulic power units. I rebuilt one of the pumps due to a seal leak. They are variable vane pumps, maybe the vane pumps are quieter than piston pumps?- chip_maker

Could be clogged pickup/ filter(s). One of mine was really noisy. Turns out the screen filter in the sump was clogged up making the pump work harder. Cleaned it out changed the filter and oil and it was a lot less noisy.- chip_maker

Anyone touch a Trak VMCsi machine?
It's Fanuc soooo..... The only thing the Haas has on it is user friendliness. With that being said, all of the other plusses are helping me quickly get over the Haas control 🤣- chip_maker

Look at DN solutions. By the time you option out a Haas the DN is a way better machine very close in price. They also offer a line directly to compete with Haas, I believe it's the SVM series. The SUPERIOR chip control alone on the DN is enough to make me want to replace all my Haas's with DN...- chip_maker
