Turning LARGE Hitachi EX2500 Mining Hydraulic Cylinder on Lathe | Machining & Welding
Ғылым және технология
This video is of a job we did for a large Hitachi EX2500 excavator hydraulic cylinder barrel off a 250 tonne mining excavator lift cylinder. We had to machine off both barrel end and barrel head flange, machine up a new barrel, then fit and weld on barrel ends to the new barrel. We had electricians through the workshop that week and unfortunately missed out on capturing some great video footage of the new barrel being machined up *sad face*. We hope you enjoy our work as much as we do!

I was just notified about your reply today. Apparently 6 months after you made it. As far as your comment goes, I see your point. My lathe only has a 6' carriage and a 10" swing and i dont think i haver gotten through a project without a few colorful expletives. Next instead of bleeps just turn up the volume on the machine noise.
at a certain point the safety glasses need their own safety glasses
Watching this in July 2024. Kurtis and Karen have come really far and grown the business and channel to a level other look up to. I have not seen a hydraulic cylinder this size in his workshop later. It is impressive
I can’t stop telling you how much I really enjoy these videos. You make everything look so easy because you love what you do I was getting nervous when you were cutting the bore end but you knew how far to go. From a tradie to another tradie YOU THE MAN
I like machine noise!
I looked at the screen and had to double check, there was this stranger doing the work. Then I figured it was Kurtis with no hat

I am engaged in the same repair of hydraulic cylinders, it is interesting to watch your videos
Beautiful job as always.
Been mining for 10 years and I hope you charged the dogs a mint for this quality work.
I believe that's the biggest hydraulic cylinder I've ever seen removed and replaced. I really enjoy seeing this kind of work done so well and professionally. Thanks!
That was a beast!
@cuttingedgeengineering I have watched your videos on FB and just switched to KZread. Going through and watching the early ones truly show how much you have expanded on your shop and content creation over the years! Amazing work! I look forward to seeing some new videos.
Wow! Big job and well done as always.
congratulations, you have a spectacular workshop .... you have photos of the internal machining process of that long cylinder.
Nice. Thanks Mike
Way to go, Carl!

Im hoping you'll be reading this. I can across your videos by accident about a week ago. The few i watched was from 2 years ago, i liked them so much i went back to the starts of the videos. So im going to slowly catch up. Im in a small town in northen thailand not much goes on here. So your videos are a welcome to my dull boring life.

Finally i found what i have been looking for at 0:33 seconds on this video clip . I did scour all your videos and it is this video showed 800x4000 on right far end below the lathe . Win Ho lathes ( Taiwan ) are 760x4300 that is their biggest . Thanks a lot Boss .
Nice work.

It's hard to believe such a heavy workpiece can be supported by that little tailstock center.
That puny hole in the first 10 seconds is so important for this job.

👋 👍 🙃 Greetings from Tanglefoot, Texas, USA!
It's 2024 and I watched all your new videos maybe since a year. And now, just for fun, I had a look at one of your first videos, this. This video is still interesting, but it's amazing how you developed so fast to a confident presenter. And great video editing and all that. Wonderful!

Hard job 👍👍😊
Hello, you chaps, have been watching your videos for a little while, allways interesting to see such large lathe work. I am a 74 year old Joiner have done quite a bit of Wood turning but never had a Metal lathe. Also like the Staffy he looks quite a character. Will look out for more of your videos. Stay safe, and healthy. Best wishes Geoff Lewis, Wales, UK, 🏴🏴🏴

Always impressed by your work. In my opinion today’s high tech CNC machines remove so much skill from a machinist, not that there isn’t a place for them there certainly is in high volume production, however manual machining is much more satisfying. Just my opinion.
Must be serious weight on that centre at the start, loving the in video comments

@@CuttingEdgeEngineering WOW i looked them up they have a live center MT 7 capable of 20 ton workpieces. Very impressive to watch, i would have continuous sweat running between my buttcheeks machining this piece and quadrouple check tailstock fixed in position and tight. But luckily i am only a hobbyist and don't have to worry about these kinds of projects. So the steady rest is only installed just in case shit hits the fan to catch the barrel from falling down ?

I have been watching your videos and each time I am in amazement of the knowledge and capability of dealing with each job. You are a true craftsman with a great health and safety officer 🐕 Keep up the good work.
Looked a bit smaller than your usual ones!!
It didn't look that big on the machine , but man that's massive.
Nice job Kurtis, that looks like the cylinders we used to drive the electrodes on our steel furnace, just about the same size with just the one port on the bottom. The hydraulic guy told me they were from a mobile piece, can't remember what though. Enjoyed, cheers mate.
it's the same as my work in Indonesia

I notice a lot of smoke while the welding operation is going on. Is there some sort of fan or air system to remove the fumes and smoke. This process does not look very healthy.
I will never understand how that live center can support that much weight 😮
@benrivenbark

If you really want your mind blown then just know that is only 1/3 of the weight that the live center is good for. It's a 2 ton cylinder and that live center can hold upwards of 6 tons.

Good job sir! PD: put some fan when welding to keep away fumes!! Fcaw is hazardous.
That has to be the least "steady" rest I've seen on a big lathe, and mine is a tiny 14x40.
It would have been nice to know what you were fixing.
Did you use a hard wire or dual shield wire to weld that? Any pre heat or post heat?
Are those wooden saw horses lol?
Love it! What do you think is the most common reason for cylinder failure? And do you stock the barrels and rods?
@CuttingEdgeEngineering

Hey mate thanks for watching. In my opinion the reason for this failure was from factory submerged arc weld left a hole in the first welding pass. On many excavator cylinders this a common reason. We stock some high volume barrels and rods 😎👍
