Turning LARGE Hitachi EX2500 Mining Hydraulic Cylinder on Lathe | Machining & Welding

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!

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

[billtheunjust]

I really appreciate the intro where you show us where these pieces go on the machine!

[daniellopez]

@cuttingedgeengineering I have watched your videos on FB and just switched to YouTube. 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.

I would have liked to seen you putting your work piece into the lathe and centering it as well.

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!

[chrisfalcke]

Nice interesting video - but your more up-to-date ones are miles better! Keep up the hoofing work

[johnmcclain]

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!

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

Why do I like this master?so this is for the fact that he approaches the case with all rigor and discipline.And he gets real things.

[vincentwilson]

I’m so glad did you take pride in your work you do good work you’re good machinist

[thunders]

I am engaged in the same repair of hydraulic cylinders, it is interesting to watch your videos

[brettymike]

I am constantly surprised by how much weight you can support on that tiny tail stock centre point! :-O

[arturobayangos]

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 .

[gerjaison]

Love that 4m center to center lathe. Hardcore!

[mathankumar]

Thats a huge cylinder man, you’re doing a great job and hope to see more big job videos

[beaversixniner]

This video should have 10 million views

Been mining for 10 years and I hope you charged the dogs a mint for this quality work.

[johnhill]

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.

That is one massive ram . Been there done that . I just got done working on a 6090 Cat Face shovel so I can relate.
