Making a 100T Heavy Duty Mining Jack Cylinder Rod | Machining & Threading

This video is a job we did to make a new cylinder rod for a 100 Tonne Edmo heavy duty hydraulic jack that is used to lift mining trucks and excavators. The rod has scratches and dents in the chrome and the top of the cylinder rod is damaged. This shows the step by step process to make the new cylinder rod including machining and thread cutting. To start, we remove the piston off the rod and that will be used to test the thread on the new rod. We machine up the new cylinder rod using a 6” inch diameter induction hardened chrome bar. We need to machine both ends of the cylinder rod, the first end we drill and bore the hole to suit the load cap. Then we machine the other end of the rod by machining through the induction hardened chrome layer before turning down the OD and cutting the 8tpi external thread for the piston. We finish the job by installing the piston before drilling and tapping a hole for a grub screw to lock the piston on the cylinder rod.

We have sometimes been calling in consultants with fees upwards of 2k$ per hour, and it's still incredible value for us compared to having someone with that expertise on staff full time. Also, weirdly enough, a more expensive IT consultant is automatically considered to be higher skilled than a cheaper consultant.

[@quadrannilator]

its actually much cheaper than rechroming, at least where we do it...

[@hannahranga]

​@@quadrannilatorwhat makes rechroming so expensive?

[@quadrannilator]

@@hannahranga Where I work, our chrome plater uses electrolytic plating. The only other alternative being thermal spraying. If the cylinder rod is just plain carbon manganese steel, you can de-chrome it using chemicals. But, many a times cylinder rods are made using steel with alloying elements, most typically Nickel and Chromium which enable them to be hardened via heat treatment, such as this induction hardened rod which Kurtis used in the video. So electrochemical dechroming is not an option because it will also leech away the Chromium inherent in the base metal. Such rods are also badly damaged with deep dents and scoring, in which case the chrome deposition also has to very deep. Typically cylinder rods are chromed and then ground in multiple passes with radial chrome thickness typically not exceeding 75microns. Straightness, Runout, Size and Surface Finish of the rod are very important for good functioning and life of a hydraulic cylinder. You don't even know how bent an old rod might be - so rechroming it may need high thickness and make it difficult to achieve geometrical accuracy. The old material will have internal stresses and micro cracks which may have already weakened it. Electrolytic plating is a very hazardous process involving toxic chemicals and gases and hence is done in only special facilities under licences and big environmental regulations. So this makes the overall plating and regrinding process an expensive affair. Its just much easier to buy a plated rod or get it plated and ground from new base metal. The cost of plating, which also consumes a lot of electricity, as its area gets larger and maintaining all its accuracies in long and big rods often far exceeds what you pay for a new bar of raw material. And you also have full control over the alloy composition, heat treatment and chrome plating process if you make a new rod. I hope my experience was a used reply for you! 😀

As for the Butcher birds, most Aussie birds will take a very long time before they will take food from an outstretched hand, I found years ago with Magpies that they will happily take food from your finger and thumb but not the open hand. We had generations of them in our back yard and I used to feed them dried cat food pellets, they loved them and would come into the garage while I was working and stand behind me - I'd sense someone was there and turn around to find a couple looking up at me. A few cat pellets and they were as happy as Larry (whoever he is, or was).🌞

A friend at a wire rope sling manufacturer company needed your services years ago. Too many years. It was a 300ton x 6inch stroke machine press and it pissed all over everything pinching large collets/collars the barrel was huge. If it didn't have an electric pump? It wouldn't have worked at all. Hand pumping would have bled completely off. God how I love your work! Phenomenal!

I just love watching and trying to figure out thread cutting! Especially Metric! Love the camera close ups! Crystal clear. 😊

Using the packaging the stock came in to protect the finished product is genius.

Good morning Kurtis, it is such a pleasure to watch you thread correctly. You double check all settings before you start and reverse the motor to go back to the beginning of the threads. When I first started threading I was intimidated until I learned the proper procedures to eliminate mistakes. My only difficulties were seeing through the smoke from the cutting oil. A fan takes care of this. Sneaking up on finish and spring passes are crucial in some applications and you sir have nailed this as well. Please don't sell your talents short as you are not "cheap", you are of the epitome of perfection. Only one of my projects made it into the cabinet of perfection in the college I trained at, if you were attending my class, every one of yours would make it in. Mine did not even follow the rule assigned as it was supposed to be both a male & female 2tpi Acme thread, but I made a double start 4tpi Acme. The instructor was impressed at the tolerance I held. All other assigned projects I incorporated into a bearing and gear puller and re-wrote my curriculum to include all processes into a usable tool. I pulled 22 credit hours per semester for 2 years. Major in machine processes & NC & CNC programming with minor in math. Dual associate programs stacked.

Curtis - your self confident and fearless approach to thread cutting is amazing to watch. And the filming is spot-on with focus on the important details.!

Becoming my new Friday arvo ritual of having a beer and watching something get built.

[@dtom1145]

Well done and tanks! I miss my days as a machinist and these let me re-live some of those great times.

[@peterbuysen8172]

It's always a good Friday watching Kurtis and Karen. Question Kurtis what is the logic behind using a spiral tap instead of a normal tap?

[@CuttingEdgeEngineering]

Hey mate good question, Spiral taps for the metal chips/swarf out of the hole and not push it into the hole 😏

You guys rock The skills and knowledge you have aquired at your young age is mind blowing. Im an oldtimer and love to teach beginners the basics of welding and fabrication ... Hard to find any kids willing to get their faces out of their cell phones long enough to learn. I pray that when you reach 65 or 70 ,that you have taught enough youngsters to fill the gap that is coming 🙏🙏🙏
