Do a post weld heat treatment of the welded areas on the flange at about 580 to 600 Deg C for an hour per inch and cool in still air, that should do two things; temper the hard areas around the weld, and relieve stress so that after machining the flange remains dimensionally stable er.
I have to say that You Australlia guys are awesome. CEE and HAL my god what a diamond discovery. Love the content. I'm cnc machinist on small 3 axis mill and im so stunned buy Your's craftsmanship! Amazing!
Hey Matt, that was a serious challenge and a superb result. That is very impressive and I can’t wait to see it all in action. Thank you for taking the time and trouble to explain things in detail and a language us non-machinists can understand. This has to be one of the best channels mon RUclips. I’d like to wish you a wonderful Christmas and I look forward to following your adventures and exploits in the New Year. Take care mate. From Dorset, England 🇬🇧
From California USA; unfortunately I knew it would warp from the welding. It is amazing how much the welding will pull and warp that thick of steel. That stress is still in the steel; but with that light of cuts the warping after the cutting “ I am hoping is not excessive”. Remember that episode at CEE where Curtis had that improperly heat treated steel that kept warping after every cut because of the internal stresses! I would recommend be careful and Do not cut the O-ring groves too deep. Leave enough rubber standing proud of the face so that the O-rings can compress down and seal. With the amount of torque that thing is going to have on it might cause it to start walking around on those bolts and possibly even loosen the bolts. This is so interesting. I am definitely not going to miss this.
Yeah. New to the channel. Living in Sydney, my workshop has a lathe and mill slightly smaller than your kit. Lathe is 240 mm between centres, Mill has a 70 mm throat and a 230 mm X travel. Build small stuff in plastic and stainless for doctors. Nice to see some decent sized jobs for a change, and the explanations of why things are so - is excellent. You have a lot in commin with Kurtis and CEE. Keep up the good work and I'll try to drop in on Boxing Day. Regards, TonyB
Brilliant video and solution to a problem. It always amazes me the range of tools and machines that are out there. Have a brilliant Christmas and a Happy New Year
Good morning Matt, I'm sat in me long johns, cold af here in merry old England 😂, and up you pop, like a warm ray of sunshine, I'll make a hot brew, and settle in Love the work you guys do. Have an absolutely wonderful day, my mate, and a wonderful Christmas, too 🎉 Edit: Flange facer eh? Who'd have thunk it lol, crazy bit of kit, hope you rented it?
Chater the bane of any machinist. Interested to see how you will recut the six o-ring grooves. Absolutely love how you show the struggles and how you overcome them keep it up!!
Always ...always ...always plan for warp when building weldments. If you get lucky and the warp is within spec, run with it. When the plates get thicker the weld gets larger, the contraction forces during cooling increase immensely. If you can't take the part to the precision, take the precision to the part. This type of flange work is critical in some pipe work when high pressures are involved. Always great to see someone learn a new process and put that skill in their toolbox.
Always loved engineering, especially cnc but get a buzz out of watching you tackle these big projects. Yet to see Cyclops make an appearance on the Hulk! Christmas greetings from the UK. Steve
Back when I was going through my meshiest apprenticeship, Whish I completed in 1971, we sometimes used tool bits called stellite, not sure I am spelling this correctly, but it was extremely tough and durable. Much harder than normal tool steel. Might want to try it sometime if you can even find it, if available.
Dude… that was an education if ever I’ve had one. Never even knew such a bit of kit existed until now. After seeing what was going on with the inserts my brain went to good old hi speed or tungsten. The cutters I learnt on & you went there too so I was a little chuffed over that, & it worked which was wicked cool. As for an easier way??? Sent it to Kurtis 😂 he probably won’t speak to ya ever again but it’s still easier.😂😂😂 My very best wishes to you guys. Hope you all have a very merry Christmas & safe & happy new year. Thanks so much for pitting this channel together. It’s helped me more than you know. Cheers everyone Patch
might be a good idea to talk to someone in the gold mining industry. they use those flange facing machines on the autoclave flange faces. the face is overlaid with titanium then machined to achieve a "gramophone" finish so that the chevron spiral wound gaskets willl seat properly. never actually done the job myself, had others who did the machining for us, but it is a very interesting process on a flange that is approx 1500mm diameter.
Hi Matt. We used to have to, occasionally, machine the “ tires” on our asphalt plants. These are large steel rings, about 3.5m in diameter, that are placed around the mixing drum and run on trunions to stay true. These things are very hard and the only way to cut them is to grind them. The company we used also had flange grinders for the same reasons as you’re running into. I’m in Alberta, Canada by the way. I’m sure there would be something available in Australia. I enjoy your content very much. Have a great Christmas and Happy New Year!
YoooMate HSS is the way and yes it takes forever. Very nice to watch. Your videos are always interesting and educational sort of. and always good material. congrats.
The flange facer was a clever machine, and you gotta love it, seeing good old HSS cutters to the rescue! Happy Holidays, and hope you folks have a great 2025!
I might have tried a brazed carbide tool. Tougher than an insert, stays sharp longer than HSS. Or even a solid carbide tool for the same reasons. Of course the heat affected zone could be avoided or minimized by welding in smaller sections or heating the whole thing before welding. But that may just make it worse. May want to consider your order of operations, weld then heat the flange up and allow it to normalize, then weld to the larger part. At least then there would be consistency even if that means consistently wrong. Can see Curtis now furiously planning out a shop built flange facer.
That's pretty wild to see how the welds have pulled in the flange face on the early cuts. It will be interesting to see the design changes (for welding up the flange ribs) for future monster tool. Thanks man. Merry Christmas ... (tuning in from San Diego, CA, USA). Good to see little Teddy playing peek-a-boo.....
It don't matter what situation you find yourself in, odds on someone somewhere has been there before you. That means that there is a good chance the right tool already exists to fix your situation, you just need to find it. Thanks to Phil, it would appear you found the right tool for this particular job.
Hi Matt I suspect a mill would work better for facing the interrupted cut, not sure whats out there these days. There are contractors in the area that do nothing but machine stuff in place for paper mills etc. If you get bored troll the Climax machine too website. HSS has saved many projects for me this summer facing big flanges full of holes. I would go with a cobalt HSS or even Stellite tools because they will last longer. Funny there is nothing like a Frenna or wobbly crane in here in the US. We just use forklifts of all sizes. Hope you have a wonderful Christmas! Ross
A perfect excuse to go buy a huge HBM! I had to machine some crappy welded steel on a clapped out, floppy lathe once. A HSS bit ground with a large radius, almost like a button, and low rake did surprisingly well at avoiding chatter and surviving the cuts. It's a geometry that will flex out of a cut instead of pulling into it, so it tends to settle on a comfy middle ground. You might want to experiment with that sometime and see if it works well with the flange cutter. If all else fails, zip tie a die grinder on your flange cutter and let 'er rip.
What watwsplace8614 said! Nice work. Carbide, CBN etc are awesome, but never overlook the humble HSS, it can shine where the others chip and fail, and can be ground into form tools limited only by your imagination. Great video Matt, keep it up! Can't wait to see that big bastard moving some dirt.
I had suspected that kind of sorcery existed, so it was very interesting to see the flange facer in action but aslo wondering if the stroke length of a shaper would be enough to do that job (with the shaper supported on a giant riser base). Everything here in the land of banana units as Kurtis calls them is beginning to shut down for the holiday season also. Cheers to you and HAL team.
Heat affected zone at the extreme OD is a bit of a trifecta. Not only does the surface hardness increase, your rigidity decreases, while your surface speed increases for a fixed RPM. The last one often gets over looked. That's a significant delta from your ID to your OD. HSS is probably where I would have started. You have full control. Just playing with the tooling relief can drastically change harmonics. Difference between having a sled at the back to resist diving or having a guillotine that dives straight in as soon as the surface hardness subsides. Moving everything around the yard probably would have tripped me up more than dialing the cut in. Love those yard cranes. I've only seen one at a scrap yard in the USA. For the longest time I assumed it was a home made contraption.
Hi guys. Just a theory, but to finish off you could fabricate a device that would hold a grinding wheel that would fit on the unit to give a lovely finish.
what a great show case to show your skills,, ,getting Teddy's hands dirty ha ha ha looks great :) looking forward to the next vid Merry Christmas and happy new year :)
Watching from the UK. I used to work in a naval dockyard. They had equipment like that to machine mountings for weapon and radar systems. Also had an 80 foot long lathe for machining propellor shafts off ships before they had on site machining gear. It sat unused for a long time, no one wanted to buy it, so I think it was scrapped eventually.
That is certainly an interesting tool I have never heard or seen of them in the 5 years that I have been watching machining content on youtube, both your channel and Kurtis's are my favorite Australian channels. Wishing you and your whole crew a very Merry Christmas and a Happy New Year, from Burpengary QLD
Wow Just how big can you go? Amazing repair and using old school tools hand ground is terrific. Great job and as I am 95 I really liked watching. Could another flange be made up and added to the existing one? Maybe just a thought. Carl. My first lathe was flat belt drived from an overhead line..
Wonder if a grinder attachment could be designed for this type of facer? It would need brushes and slip rings for an electric grinder motor, but that's a pretty common application. Also you would need some type of spring tensioner and gauge to keep a constant grinder wheel pressure against the face as the grinding wheel wears down.
No problem for you guys, slight adjustments here an there, bobs your uncle, another job done boys, and quality work done as usual 👍😊. One of your best ones yet, Have a great Christmas and holiday, regards to you all and your families 👍
Sharpsburg, Georgia USA Great video, I've never seen that machine before, very interesting to watch. My first thought when i saw it operate at that slow speed was its like my shaper. I wonder if a bull nose shaped HSS cutter would handle those heat affected areas, ive had good luck but i don't think I've had to deal with steel that had 10 heavy passes of heat put into it, 2 or 3 maybe. Just an idea, i think its the problem solving part of the job that keeps us coming back.
Very interesting bit of kit. Off the cuff, if the cutting bit was rotary (endmill) with greater step-over and depth, it might be quicker, idk. Or, you could map how much these warp and keep a log of them. Then mill the opposite expected feature in it so it pulls straight when welded...if you could pull that off you've be revered forever as a wizzard. Have the beard to boot :)
Do a post weld heat treatment of the welded areas on the flange at about 580 to 600 Deg C for an hour per inch and cool in still air, that should do two things; temper the hard areas around the weld, and relieve stress so that after machining the flange remains dimensionally stable er.

Why put a piece on the lathe when you can put a lathe on the piece.
Merry Christmas Matt and crew.
Looking forward to next weeks episode.
Nice work and an interesting bit of kit.

Good job Matt - I would have used a file, or three 😂
I will say that the dialing in of the flangerator would have been really interesting to see given the warping. Really interesting tool.
Thank you Matt. Wishing you, your family, personnel and dogs a very merry Christmas. From South Africa that is bloody well shut down the whole year! 🤭
Best vid yet! Super interesting and entertaining!
Just found your channel and love your can do attitude, You could almost be a Kiwi, almost. You guys have a great Christmas and a happy new year.

Hi Matt loving the videos, watching in sunny Cape Town
I would not have thought that such a thick plate of steel would warp that much.
Hi from sunny South Africa. We also now shut down for hloiday. Also a bit of rain. Happy Holidays !

Off the cuff, if the cutting bit was rotary (endmill) with greater step-over and depth, it might be quicker, idk.
Or, you could map how much these warp and keep a log of them. Then mill the opposite expected feature in it so it pulls straight when welded...if you could pull that off you've be revered forever as a wizzard. Have the beard to boot :)
Enjoy the video very much you do so good cant wait to see the next one
