ST30 Lathe Rebuild and Alignment

[@jasonruch3529]

Dam...i cant believe this vids a yr old😢..i hate the algorithm....i love these vids😊❤

[@JosephEllis-f8b]

Great video!! I'm an independant machine repair company myself, I'm based in North Carolina. I'm in my 50's and have been doing repair for almost 25 years but I still like watching and learning from other people like yourself. Being self tought it's nice to verify that how I do something is the "correct way" or at least the same as someone else does it. Keep up the great videos!

[@cncrepairman]

Thanks for the feedback. Hope to talk with you on the phone some day.

[@hosseinranjbar2810]

Mmmm. Good on you!

[@hosseinranjbar2810]

In my opinion your comment was the best among the all I read here.

[@Xphinity]

Certified HAAS technician here, and this video is invaluable! Thanks for the total breakdown of an old gal, most of the training done now is on modern machines, though they do have some relics too. I can tell you take care of your machines by the things you noted and replaced, love to see it man! Be safe!

[@cncrepairman]

Thanks for the comment and watching the video. Thanks for fixing machines out there.

[@jeffsprague4961]

Thanks Aaron, you just left my shop after repairing my TSC in the mill. Looking forward to you aligning the ST30LY next month...thanks for the years of service you have provided. JS

[@marcus18888]

Hell yeah that was great, I'm in the process of doing an SL20 with live tooling, I learned a lot from this thank you!

[@benmartin9648]

I enjoyed hearing the process you use in diagnosing the different issues as well as how to approach things for disassembly, assembly and alignment. Helpful information even if you are not working on a Haas.

[@maloyaircraft1174]

I like these videos. It was pretty detailed in terms of the breakdown of the machine. Would have been great to see estimated parts cost for all the individual components you replaced. So someone considering a machine of this condition could estimate the cost before taking on a project of this nature.

[@mannycalavera121]

Thanks for producing this content, it's pretty niche but informative

[@alekseiradik]

Good video. We wanna more, with more explanations and blueprints.

[@Vikingman2024]

Great video! I wish I had your ambition, old age has sapped by strength and ambition, please keep up the instructional and informative videos, they are much appreciated. Older Mori Seiki stuff would also be appreciated, thanks!

[@DanRudolph]

Really enjoyed this review of the rebuild

[@PastThePoint]

New sub here! I really like this style of video! The only thing that I could think of that might be really cool is before and after jogs (with sound) and a simple test part. I'm sure when you're done, with your attention to detail, these things run great!

[@sr20starlet]

Nice, that was a great video. really interesting seeing the whole process. I thought the pacing was good, if you know what you're looking at all the information makes sense. Definitely keen to see more like this

[@Redbarron32284]

I’m currently learning how to do alignments and this was helpful. Appreciate the breakdown would love to see more of these types of videos.

[@KravchenkoAudioPerth]

I learned a lot. And I really appreciate the time you put into this video. If you make them, I'll be watching. Mark

[@frankhuston2616]

Great video!!!! Great job!!! Love your work!! Keep up the great work!! Would like to hear what kind of money a person spends on a reman like that.

[@сашапашп]

Nice complicated video! Want to see more in depth view wideos like this!)

[@hutchinsoncaraudio9234]

That's intense, definitely the most crazy overhaul I've ever seen

[@kevinc9006]

Why would a 1990 vf3 throw z and x axis amp alarms when the axis are not moving at all and I run the spindle speed up and down . Regen is good (7.5 ohms) amps passed inspection. Im aiming at the vector drive.

[@J560iH]

Thank You. Still dealing with multiple crashes( found 6 remnants) on a single spindle from last week, alignment next week.

[@manikandang8806]

😊 I am Indian in Chennai great video I likes this video

[@jameshollingsworth4714]

Great information, I'm doing some of the same on a Doosan DMV-500, 1994 vintage. Forklift and hammer prove to be delicate machine tools. Thanks

[@Unruh1087]

Where did you learn how to do all of this? Great information. I will use all of the tips and tricks.

[@Travisfromoregon]

Another great video, was watching so guys tram in a umc the other day with a laser measuring system. Could you explain a little more on how the incoders and brakes work?

[@jasonruch3529]

That was perfect! Thanks for the VERY INFORMATIVE video!!! 😉😁

[@Petertje94]

Best video seen on this subject! Never seen a spindle aligntool. Didnt know they existed😅 i used to turn a shaft 200 a 300mm long to check spindle alignment. to bad its a haas machine. sorry just dont like those. Would love to see a video of a full alignment on a doosan mill/turn (mx/smx).

[@cncrepairman]

Thanks for the comment. I’ll have to make a Mori or Doosan video. I just did an alignment on both.

[@kamil19951]

Very interesting. I'm just battling with my old wire edm. Everything I cut comes out 0.01mm smaller in Y. Comped backlash, but its still doing it. A video about backlash, ballscrew/motor couplings, thrust bearings would be interesting.

[@MeDieValUKRAINE]

to do a main spindle or a sub-spindle shift adjustment use two dial indicators from casting to moving part, helps a lot to make a parallel shift of few thousands,

[@rdc02271]

Newbie alert! This is a great video! Please, keep them coming! By the way: what products do you use to clean up all that nasty stuff? Thank you, Jorge

[@cncrepairman]

I use HammerMan Degreaser! Keep an eye out for it on CNC Replacement Parts

[@andrewh2341]

Like the idea, maybe break it into a few video 10-15min long. It would let you slow down and add detail plus the video would feel a little less like drinking from a firehouse :)

[@jesseskellington9427]

Do you have a video on how you remove the dried on Tramp Oil from all the parts? Thx 🙂

[@cncrepairman]

Not yet. If you look on my website, I have a degreaser called Hammerman degreaser. It’s actually a really new product only designed a few years ago by an engineer in California. It’s super eco-friendly and also really tough on grease and easy on your hands and lungs.

[@MarkAW2003]

"All the bolts and fasteners that go into the trucks are metric, but everything else is standard". ???? Metric is THE standard!!! What crazy part of the world uses non-metric bolts??? Love the videos though. Keep 'em up. (And hate inches and imperial fasteners with a passion....obviously...)

[@lukekortokrax8884]

Would you happen to know how to turn parameter 700 off? Realigning an St30Y and I'm struggling to get the Y axis dialed in.

[@DJ-yp4kc]

did my old HL....still running today

[@MrAirsoftmodz]

hey, i have a st30 standard machine 2011. the chuck side moving cover bolted to the side of the turret rubs a lot on the machine panels. any advise on how to repair? i think the guard is warped since its so thick its very strong

[@stephensmallbone5701]

Nice video. Picked up afew tips thanks.

[@marknouj]

Wow, I had no idea there were machines out there in this rough of a shape! Can you share how long this rebuild process ended up taking and roughly what the cost to the customer was to get it back in good condition?

[@brentthompson2889]

Awesome video, great info!

[@robertschauer376]

Yes, more rebuild videos

[@Agent0004]

this is gold..👌

[@abdalrohmanmousa7405]

How much did this cost

[@letslearn4funn]

Can you please provide electrical and mechanical drawings of this machine

[@CoryE-gv8gm]

Question- how do you align the OD tool holders to the spindle centreline, on a non y axis st30 lathe? Are you kinda just stuck moving the spindle/saddle/wedge to get it in Center?

[@cncrepairman]

Move the spindle or wedge. It’s easier with the test bar

[@CoryE-gv8gm]

@@cncrepairman Thanks a bunch for the reply! Thaaat's what I was afraid of haha. I guess with the test bar, you can stick a dial indicator in the end of it, and then dial in a boring bar holder? Or maybe more ideally, a fixture that goes in the OD holder slot on a BOT turret, with a hole put at the center height of a tool (since the boring bar holders have the eccentric cams to adjust as needed)

[@davidl.579]

I saw the stone you use about 27 min in. Has it been ground flat and do you have the mate or do you use it right out of the box, cause I only see one?

[@cncrepairman]

Just used it out of the box. I know there is a deep world when it comes to flat stones. I just wanted to knock off the high spots.

[@spikeypineapple552]

Mate, this is so good. Can you dfo doosan next lmao

[@densmoreworldwide7]

Wedge adjustment for non y axis st25 tips? Thanks

[@cncrepairman]

Really no difference. You’ll need a wedge tool. You can get them at Cnc Replacement parts.

[@nicholaszimmer663]

How many tools do you travel with? Like in pounds?

[@cncrepairman]

This job was probably 400+

[@465maltbie]

That was a lot of work, how many days did that take? As my friend said when he had to repair a used machine he bought, " I had to beat the bubba out of it..." . ha ha. Charles

[@dabooge]

How many hours did that take? And cost. That machine looked like a write off.

[@mikeygoertzy4524]

so badass

[@Ddabig40mac]

Good stuff!

[@disfordiesel8219]

Could you ballpark the cost on this rebuild?

[@Petertje94]

34:00 🤣 it's better to have a few left than to be a few short. Nothing is worse that when you are done, a week later you get a call that the machine has an axis overload because there is a bolt in between somewhere.😅

[@cncrepairman]

Dude. I have been there. I smashed a rail once because of an Allen wrench. I’m still ticked about it but I learned.

[@135SoHc]

New or salvaged/refurbished parts ?

[@PreciStrike_96]

LUBE LINES SUCK!!! I thought I had my work cut out for me when I was just aligning the sub on a DS30y. I had gotten all the way through the alignment and started putting sheet metal back on. In the process I guess one of the lube lines got slightly bent down and when I jogged the B-axis forward it hooked on the rail and yanked the fitting out of the truck. Of course, it was the front left one on the turret side so I had no way to get to it as it's sandwiched between the rail and the subplate with no way to get a wrench on it. So, off came everything again. Had to jack up the sub and unbolt the truck. Then I was able to slide it off the rail and flip it around. I plugged the stripped hole (from yanking the fitting out) and then used the hole on the opposite end. Luckily they're reversible and have them on both sides. Then I was able to put everything back together again and redo the whole alignment process. As for the turret, the subplate makes alignments easier. But it also seems to be the weak point so the turret moves very easily. Probably did it 20+ times while working at that shop. Helps if you make little adjustment blocks with jack screws. We were initially taking them off each time, but ended up just leaving them on as we probably did it every few months.

[@abdalrohmanmousa7405]

It's basically a nightmare I once replaced a Spindel on a Mazak multiplex without and special tools 2 weeks of work

[@scottfranklin3713]

Not sure how old this machine is but is this effort cost effective? I would be worried that you would spend $100k to rebuild a machine that is ultimately worth $75k. I guess it would make a difference if it is your machine vs a customer project but still seems like a ton of work and parts. Great video nonetheless!

[@CeNuVezi]

Man a loooot of work , first just to clean all , after to install new items ….

[@Big_White_X]

not realy need to replace the X rails untill you sell them..., the dent is in the end of the stroke.just grind it with stone to put a new bearings.
