SNS 164 Part 2: Horizontal Boring Mill
ฝัง
- เผยแพร่เมื่อ 14 เม.ย. 2017
- I use the H.W. Kearns horizontal bowing mill to set up and bore out the center of the two large gearbox stands I recently fabricated. There was a mistake made on some drawings and the incorrect dimensions were given when burned out. Instead of making a mess of them with a torch, or wasting material, I set them up in the mill and bored them out as needed.
In the mix I also show my dads Starrett 2-32" Starrett inside mic, as well as his Starrett 36" vernier calipers, which I use to measure the bore. - วิทยาศาสตร์และเทคโนโลยี
lol
Heavy industry doesn't have tools big enough for the job
"Ok. I'll be right back. Just let me just get some stuff from home."
Well not every shop has Abom size tooling at hand.
😂😂😂😂, that's true, and it happend for me in the maitenance sector
You know you've entered the final stage of a project when the finger-pointing starts.
I work in telecommunications. we start the blamestorming in the planning phase.
ok ok ok thats funny.
Adam, your dad and grandad must be so proud of you. You're a first class machinist, and a classy guy. Hope you are enjoying the holiday with family.
Happy groundhog day
Even tho this may have taken a bit longer than a plasma or flame, the finish says it all. Another quality Abom job! It shows that your shop takes pride in the work they do. Nice that your boss lets you video these things, he's missing a lot of free advertising tho.
I hope I can hear and understand you talk about the issues you do, I admire you, and every day I watch your video thank you.
So nice to see someone working on large equipment these days. So few of us machinist tool die makers around. Keep you the great work too. Victory First.
Nice work stepping up to the line to fix the boring issue. Great work on that and thanks for the vid, Abom!
Adam thank you so much showing us this cool stuff for me it gives me more than entertainment it gives me ideas and ways I can think of of doing so menny thing. One day I hope to put to use with my plans.
It's good to see that even today with modern technology nothing beats the human feel for accuracy. Keep up the good work of inspiring us Adam
Thanks for the trip down memory lane used to work a Kearns 25year's ago great video chatter is the killer of all tools used to reverse cut to finish worked every time thanks
Super cool Adam! Love the work and the attitude. 👍
I'm not a machinist...never will be a machinist , but I love watching these posts. The time and care that you take with every job you do is impressive. And the respect for the machine and care you take of tools you handle shows a real master tradesman at work. Also your videography and editing skills are just as impressive. Thank you Sir.
Hi Adam. Nice save got to love that that big boring machine. Thanks for the videos .
You are a stand up guy. I love that you help your bosses out with your own tools....
The shop I worked in used a Giddings and Lewis 60 inch HBM modified to cut threads on large diameter casing pipe. We fought chatter all the time. But what a beast!!! I was maintenance (sparky) and those machines were my babies
We're looking at some nice big G&L machines right now.
Wicked cut Adam, MI is lucky to have someone willing to fix the problem while others point the fingers. Turned that ignorant iron back into something usable.
I wish I knew half of what you've forgotten. thanks for the video. please keep them coming, it means a lot to some of us.
Adam, you and the people you work for have my sincere respect concerning your general attitude about how to react to mistakes and problems. Assigning responsibility for errors can be valuable if the process is centered on making clear what the problem is and what needs to be done to correct the situation. When this process gets in the way of getting the job done, and done well, a lot of finger pointing is not very useful. Nice example of using several measurements and tools to come to an "average" accuracy that is acceptable for the job at hand.
Lot of guys don't like boring mill work but I always had a great time with it. You just have to take your time and think about what your doing.
Adam.... I know we have been back and forth on large verses small jobs but after seeing this I am glad my fixes are on SMALL parts! Honestly after seeing this I think you will tackle almost anything. Believe me I know about design changes and the lack of communication. Good video and keep them coming.
As always, like a pro! Thanks for showing.
Nice job Adam, keeping customers happy.
Great work Adam got to love that boring mill!!
These are the GOOD videos that built your channel, Mr. Booth.
When I started out machining, an older guy in the shop named Steve taught me a valuable lesson - Everyone makes mistakes. What differentiates the skilled machinist from the newbie is knowing how to fix the mistake. Who did what wrong and how matters a whole lot less than making it right.
I've switched career paths and am far from the shop now...but wisdom like that applies anywhere in anything you do. :) Thanks, Steve!
love your videos, got a lot from your videos. lot of tips I use at work almost weekly
It's nice watching a guy who is proud and enjoys his work. Sometimes I really get down about constantly battling with worn out machines and customers who don't want to pay 😔
Absolutely love that Kearns. Thing has paid for itself hundreds of times over at this point. Absolutely vital piece of equipment. Whoever at Motion was the guy who gave the go ahead to buy that from your Dad when he was closing the shop; he is/was a smart man.
Thanks Adam!!!! Very cool "Gitter Done!!" job!
That guy was me! LOL! or at least I was the one who asked the boss to buy it.
Bravo on what I think is becoming lost in the world, getting the job done. Some stand around pointing fingers and arguing over whose fault something is. Then there are those who just get to work and fix the problem. THE WORK is the main thing. It has to get done and your shop's reputation can take a bad hit if it isn't. The blame can be figured out later.
Great job, Adam. Thanks for sharing.
Good videos Adam. That boring mill is a nice machine. Wife says we may go to Johns open house again this year.
Man that Kearns HBM sure is a versatile machine.
That was a nice, clean finished product.
That job required You Adam , Great job on solving the problem at hand there ! Thumbs up ..
thanks for sharing your knowledge, you're bettering mankind
A great Abom-size project successfully completed. Two thumbs up.
I spent 5 yrs on an old 1940's era lucas42b boring mill boring pasta excruding cylenders finished at 7.5 id and 6 feet long. Had to use the tail stock and a 4 in boring bar about 12 ft long. I designed and made the fixtures to hold them. Chatter was a challenge, low rpm and heavier feed with .03 to .05 depth of cut. I used .015 radius tool nose inserts. Cylenders were fabbed from food grade stainless. I countered bored each end to accept a bushing in each end to support the bar. Each bushing had a air oiler plumbed in to it for lube and to keep chips ffrom entering tthe bushings worked great! To get the travel i needed i used both the spindle feed and the table feed.
What quality work was that! Lovely welds and paint finish
It can be easy to do a quick cheap fix, but quality neat work extends your reputation. Nice job
Nice job and interesting to see this relatively big machine in action.
Adam: Great video. We work in different areas, but, I go through the same process when an "I got this" happens in the lab. Plan A, B, C, D, and E...... Thanks, we got this!
I have probably said before but will say it again. Thank you to your boss(es) for letting you filem at work. I really admire the working relationship you have with them and your co-workers. I really get the feeling that while any business has to be based around profit it is not the only thing that matters in your work place. The mutual respect, cooperation, trust and drive for quality shines through. Another great job :)
We have to get the job done, and do it right no matter what the cost is. The unfortunate mistake is still considered covered in the labor for the whole job. Not only did we build the stands, we are assembling the units together as well.
Aye, these things happen. The great thing is you got on with it and did a good job doing it. To borrow a phrase from your arch nemesis.. It's good to see your 'get her done' attitude ;) and the solutions you bring to the job. Thanks for the reply :) and thanks for all the amazing content you make too...
Assortment of indicators or "Weapons of Choice" 🔱
Thanks for the very interesting content. Your credit to your trade and the Booth name. Hate to see the videos end.
Very interesting , I was hired in the past to machine 54 inch rings on a jacked up lathe clamped on a huge face plate , centered with a tape measure, I made myself an Ajustible mike with a 3/8 16 bolt with a one or one and one quarter micrometer handle I made to measure the final diameter my boss would verify with a tape measure . After a while my boss lost the contract with a different design and CNC machining .
nice job dude I like your style and the boring mill too. Thanks for sharing Abom79
GREAT SET OF VIDEOS. THANKS FOR THE TIPS.
love watching your videos. my sister lives in milton,Florida. just outside of Pensacola. will be visiting her in May.
Yep I know Milton well, I grew up in Pace as a teen.
Hello Adam from John. I love the respect you have for your father and his/your fathers father! I know there a lot of Nay Sayers in this world and especially when they can hide behind their computer. I did wonder at the start of the video how you will go with chatter, I have had similar problems. You made a decision that was practical and solved the problem. Cheers from John Australia.
Ok on that boring mill job. I've never seen such a giant before (the machine is pretty big, too!) Greg
nice to see the final paint job those things got, too.
Thanks for the video Adam.
Very interesting Adam thanks for sharing.
love the vid ,really good machinist like always ...
I had to pick my jaw up off the ground when you opened that 36" Veneer I think you called it. Abom size for sure
That's great news Adam about the G&L, I was saying ask your boss for a vertical borer, not for this one job as one of your commenters remarked, but to increase the type of work the company can take on, therefore making more profit and saving set up time which will benefit everyone. I think the vertical borer is more suitable for this type of job but I realise the company's funds are finite. You should have a tee shirt made up saying " the impossible done immediately, miracles may take a little longer"
Real good job on the tables adam
Hi just been looking on you tube and come across this sight. Feeling very nostalgic asi worked at kearns richards from 1970 till 1984 when it closed down. The machine shown must have been built in the 50s or early 60s as i had never seen that one. we made several machines Stype SH SF SJ and SE. Several people say the machine shown was big but it was only the equivalent in size to the SH Look on the kearns richards websites and you can look at all the machines that i have stated. The big SE150 Had a car placed on its rotating table to be photographed and i also remember one of the big machines having a chieftan tank gun turret having work done on it.. Sad to say but mrs Thatcher brought about the demise of many industies including engineering! So many highly skilled men lost for good[i was only average} Luckily i ended up working as a baggage handler at Manchester Airport until i retired a couple of years ago.
Nice job Adam, i love your videos! Keep it up buddy :) Greetings from Serbia.
I worked a 5 axis Echocut boremill made by Sharman ... the damaged spindle needed replacing, it took 4 maintenance guys, two from Germany and a 5 ton hoist to remove it.....the table could turn 360*..... such a versatile MC
toujours un plaisir de vous regardez, je vous souhaite une bonne année 2019
Thanks Adam ! Great video.
My favorite words as a machinist "no critical" and "it's for clearance"
Nice job Adam, 'chatter' is a constant enemy.
Thanks Adam
Thanks Motion for video studio use.
Education for the masses your support is appreciated.
May influence a future dedicated employee to be.
Nice work, fella!
you like messing with really big things 👍👍👍
You are so right - past a certain point someone has to step up and get past the finger pointing and just get it fixed.
Scott Harter Yeah. It should be that guy over there. *points*
hi Adam! youre awesome (nothing has changed) :) thanks for your videos and hope you and your family are doing good.have a blessed day.. loves ya and asalaam peace
hii adam you really have a very interesting and versatile job
GREAT VIDEO !!
Aw hell, back when I was a draftsman, I was given a rush drawing to make from one of the engineers hand sketches. You would have thought the engineer would have known what dimensions you needed to make a drawing but he didn't. So I had to go ask him what this dimension and that dimension was and he got all upset with me for bothering him "with stuff I should know".
So, I finally got the drawing made from his sketch and something told me to make a copy of his sketch, just in case. Sure enough, a couple days later he comes up all upset with how I'd effed up his entire project and how I should be fired. Yadda, yadda, yadda.
So, finally my boss wants to see what the problem was, and he handed over his sketch and said, "Your effen draftsman can't even copy a simple sketch right." Then I took out my copy of his sketch and it showed the dimension I made the drawing by and dimensioned it . When his part was wrong because he screwed up he decided to blame me and changed the sketch and tried to claim I screwed it up.
So, when my boss got done with his boss, he was in some deep do-do.
After that incident, I would make copies of everything after that, I would even make notes of notes I gave to others to remind me I'd given people a note about something specific. Saved my bacon a number of times., even after I became an engineer.
The world would work much easier if people just did the right thing the first time. If someone comes to you for a better understanding give them a better understanding. Obviously there is a communication issue, a good manager or engineer understands that and solves any issue. A holes do what this guy did to you. If it were I he would have been fired for altering the document and placing blame elsewhere. That is completely unprofessional and underhanded.
cool story bro
you know he is working some Abom-sized parts when even Adam looks a bit smaller compared to the workpieces he is machining ;-)
Monarch and Pacemaker? Cool. DoAll, K&T, and Acra? Cool. Boring Mill? Awesome!
Well said!
Adam, you just make me want to buy a boring mill
Adam, in my opinion you should become a film director your video content and quality is excellent....10/10.
+rich kellow Thanks Rich!
ID's small OD's big. Nice re-work!
Great work Adam, i wish i was one of your customers!
Nice to see someone who gives a fetid dingos kidney about the work they do.
I was astounded at work a couple of weeks ago instead of furnishing some simple hand tools we needed, the company opted to pull a mechanic off a job to come remove some 10mm wrench size nuts. A job that had we had access to a 10 mm open hole nut driver would have taken 5 minutes actually took two days. They saved having to buy maybe a $50 nut drivers that probably cost several hundred dollars in the the end. Tools are apparently a real struggle for some companies.
thats a good job well done
what a great video. very interesting. I was wondering if you had put some rubber blocks in the upper portion of the table where it was chattering, one on each side of the table top bolted with a through hole using one of the drilled holes in the top, if that would have absorbed the vibration. just a thought. we use a vibration band on brake rotors which work great.
We have one of these where I work, a Kearnes No.2 borer. We call the horizontal borers here in the U.K, never heard of these being referred to as a mill? Great video as always.
I’ve heard it in the uk, but only from a old school guy
Now that is an A bomb size "hole in two"! What can you depend on when the drawings are wrong? Nice recovery Adam. Take care. Doug
I woulda cut the welds and sent it back to the plasma table and re welded but then you wouldn't have had a video! lol awesome stuff Adam!
I worked at Westinghouse on large G&L horizontal machines. So I’ve worked with big facing heads and line boring. On your part I would have cut with cobalt high speed and used clamps in the two top holes. Use indicators while clamping - to make sure part is not moving - if it moves use kickers. I miss my trade - I will be 77 in September.
Woah.. I finished machined 6"x10" bore on my CNC lathe the other day and thought that was big!!
Nice work ...
Awesome Adam. Thanks!
favorite specialist :))
Greatly instructional! I have not seen other videos on YT that are showing how to operate an HBM as good as yours. Bruce Whitman has some good ones too but not as extensive.
A suggestion: put all the videos with the HBM is a specific pkaylist for ease of reference.
Daniel
+AtelierDBurgoyne I'll try and get that organized Daniel.
The first thing I thought of for stiffening up that set-up was a telescopic builder's prop or floor jack, just jam it inside that pallet and see if things improve.
The second thing was just to use a ratchet strap or two.
Nice save
I worked at a couple of shops that had Devlieg's with horizontal spindle.
I worked in the design rooms & I am not a machinist.
Actually, the one shop I was told by a customer - was originally the Devlieg plant before they moved to Royal Oak, MI.
This makes me miss being a machinist so much
Those transport stands are Wicked, I'm sure curious to see what kind of transmission those support. In less than a month I'll be down your way to the "Real Florida" (don't worry 'bout me pestering you, after coming through DeFuniak going east to coast due south of Tallahassee, small coastal town called Panacea) to do a couple weeks worth of a whole bunch of Noth'n but hold a fishing rod and crank it every now and then. Been coming to that part of Florida better than 30 years, hoping to retire there when the Wife retires. The Sea and the real south is in my blood.
Hey Adam great vid as usual. I've recently purchased an ex Tech Colledge Kearns Staveley "S" Type HBM and so looking forward to using it once I update the original electrics. The machine is in excellent condition with very little use for it's age. Kearns must have used a bad batch of paint as it needs a coat of paint which will happen soon. Cheers.
That's great! I'd love to see that machine if you care to share some pictures in email.
Hey Adam. Thanks for the reply. I'll send you a private message via FB for your email address or you can contact me via my web site www.grahamsengineering.com.au I'm in Brisbane Australia. The HBM that I have is a later version of the one that Bruce Whitlam has. Mine is the last of the line being a metric unit. The slideways are perfect and all the Gibs are in their original factory setting. All the slides are still tight. The paint is badly flaked but I will strip it back soon and give it a coat of Machine Grey. I'd be very happy to share some pic's of it with you as well as the other gear that I've been revamping. Just recommissioned a Churchill NB Model Surface Grinder, built in 1959 and still very accurate. I've been doing a lot of filming of what I've been doing and will start to edit and upload soon. Fingers crossed the vids come out ok. Cheers for now.
Good work, try HSS tools with some positive rake tipped tools push too much on Fabs.
Another tip is to bolt MASS to job if its thin to reduce vibration.
Nice solution to the problem Adam. I did not realize the HBM had that much capacity in the y(?) axis. It would have been tough to take that small of a cut with a torch, even if you made a ring for a guide which would have been a lot of work too.
Bill it has a working envelope of about 36x36x36.
could you do a video covering the tools/boxes you keep at work?
One thing that I found often worked on frames and other "flimsy" work is to increase the cutting speed and feed rate. This does several things. The work (and possibly the tool holding assembly) is being excited at its natural frequency by the cutting tool. By speeding up the cutting speed a fair amount you are more likely to get out of this frequency range than by slowing down a little. The increased excitation frequency is easier to damp with things like sandbags, etc. (as others have mentioned).
Taking a heavier cut loads the whole plot and the increased forces tend to dampen vibrations. This is often seen on lathe work using carbide tooling. Taking a light cut makes the work vibrate like a bell. But if the cut is made according to the insert manufacture's recommendation the tool cuts smoothly though the finish isn't as fine as you might like because of high feed rates. Generally this is ok as the areas where a bearing might be fitted are often the only places that need a fine finish.

You didn't have a 27" diameter drill bit?
Only 26 and 28, his 27 got lost some time ago :(
the thing would weigh like 4 tons depending on whether it's high speed or carbide.
it probably needs a 500 morse taper drill sleve XD
@@yo64yo 😂😂😂
nice job
