60 HP Makino Cuts 150 Pound Titanium Aero Part With Kennametal 65 Insert Beast Cutter

I'm not a machinist, but I did a few months worth of milling and turning in college, and probably a week of 3 axis CNC, but that carbide insert drill bit is most insane tools I've ever seen.

Titanium is a really weird stuff. When working with it, you'd think it's like ten times as strong as steel. But it isn't. It has about the same strength as a modern alloy steel actually. The main difference is that it's about 30-40% lighter. And that it really doesn't like being worked on. Think of Grade 5 Titanium as stainless steel times three, in terms of being difficult to work with. Don't even think about using HSS tools for that stuff. A few years ago, I needed a custom replacement part. A bolt, made out of a strong alloy steel, about three inches long, with a diameter of 7.96 mm, and with internal threads at both ends, about 8 mm deep. I made a technical drawing (I'm an Industrial Mechanic) and had send it to about ten metal working companies, asking them for an indiviual quote. All of them were willing to do the job. I had picked the lowest price and made the order. About a year ago, I had the idea to replace the bolt with one made from Grade 5 Titanium. I've sent the same drawing to about ten metal working companies again (I've ensured that they work with Titanium beforehand), and all of them had refused the job. I've mentioned that I'm aware that it will be expensive, but still, all of them stated that they can't do this job economically. Then I've decided to do it myself. I don't have a lathe, but the bolt needs to have a diameter of 7.96 mm. And you can get 8 mm round bars of Grade 5 Titanium. It's only four hundredths of the diameter, what means that I only have to remove two hundredths from the surface of the bolt. Two hundredths of a millimeter isn't much, so I thought I just could grind it off with sandpaper. The bolt only needs to fit. It doesn't matter if the diameter is a few hundredths thinner at some points. So I've clamped the bolt into my drill, took some sandpaper in my hand and wrapped my hand around the bar, moving it slowly up and down while applying some pressure to the sandpaper. Inbetween, I've measured the diameter with a micrometer. So far the theory. I was totally aware that it will take some time, since grinding removes only very little material. But I thought of something like 20 minutes maybe. I've already done something similiar with steel. You wouldn't believe how long it took with this stuff. The bar got hot from the friction fast. Extremely fast actually. I had to dip the bar in cold water every ten seconds , to not burn my hand while pressing the sandpaper to it. It took about four hours to grind that 0.02 mm off, not kidding. My fingers were hurting already, from pressing the sandpaper against the bar. But eventually, the bolt was fitting perfectly. Then I needed to make the internal threads at both ends. Didn't need a lathe for them aswell. They didn't need to be very precise or exactly centered, since they're only meant to hold two screws with washers to keep the bolt in position. So I could easily do them by hand. But the toughness of this material is ridiculous. I totally should have cancelled the project at this point. But I hate it to have spent a lot of time on something and then giving up. I rather add ten times the amount of work to it to get it done, than having wasted the time and energy for nothing. Drilling was a big PITA. The heat development of that stuff is ridiculous. If you only have oil as a cooling agent, you'll ruin a drill for every mm of depth. Have switched to hard metal drills and still ruined two of them. The tip of the drill starts to glow basically as soon as it cuts the first chip, despite being covered in oil. The oil starts to smoke immediately, as soon as the drill starts to cut. Without a proper cooling system or special techniques like high speed cutting, you basically can't do anything with Grade 5 Titanium. When hand-drilling it, you have to make short chips and cool it down after every single chip . After two hours, I was finally done. For just two small holes, only about 10 mm deep. That's crazy. You can probably already imagine how the thread cutting was going then. After about four to five hours, I was almost finished, but then I broke the thread cutter while making the second thread. If this happens, your piece is ruined. You can't get the remains of the cutter out of the hole without special equipment. Since I wanted to finish the project at that weekend and I had enough material left to make a second bolt, I started from scratch. (repeating the four hours of grinding and two hours of drilling...) This time, I did the thread cutting ridiculously slow. I had to put as much force on the cutter that it was visibly twisted before it started to finally move through that stuff at all. I've even increased the core hole diameter for the M5 thread by a tenth of a millimeter to reduce the burden on the thread cutter, but it didn't help notably. It didn't feel like cutting at all, but more like pressing the thread into the material. I could progress only a few tenths of a millimeter each time, before having to twist the tool back and cool the whole thing down, and despite all the lubrication, the cutting produced gnashing and cracking sounds like an old pirate ship. The cutter was sharp and new, but it only started to move forward when I was almost at the breaking point of the tool. It took me about three hours per thread and I was sweating more from hour to hour, because of the fear that the tool would break again after all the work. After it was done, I swore to myself to never work with Grade 5 Titanium by hand again. TL;DR: Titanium is a really weird stuff.

I wouldn't be smart enough to clean the toilets around that shop.

In a couple weeks time, we got to watch Titan unwrap a new machine. He got it installed. Received an exotic material titanium. Unwrap new precision workholding. Design and program a complex part. Put it all together and share it with a manufacturing community. Priceless.

“CNC Jock” is not a phrase I ever imagined needing before today

This guy could also sell gym memberships, AR-15s, energy drinks, bug-out supplies, and trucks, hah.

I can feel the machine vibrating in my house.

here is a guy that is absolutely fascinated by his job... never thought I run into a muscled-up CNC-Geek - I love it xD stay like that.

Manufacturer: So uhmm...how many carbite inserts do you guys need? TITANS: Yes.

As a mechanical engineer this channel is one my favorites. Great job! I like the details

A professional machinist. Nothing in the world like a professional. Their artistry makes the world a better place.

Technical stuff like this encouraged me to follow an applied mathematics degree and leave machining behind. Best choice ever. Why be the grunt when you can be the creator of this machines. Mad respect for this guy, he knows his shit.

Titan you are a titan there is nothing else to say. You made me realize what I'm worth and I made a business out of it at 22. BOOM!!!!

Titan and his crew have a positive attitude and they take great pleasure in producing precision parts made in America. Manufacturing in America needs people that bring excitement into a trade that has had too many long faces. I like the vibe. Kurt Veith

Props to you, I worked on a cnc machine for a year and a half and hated it. I'm definitely in awe of the people that do this for a living.

As someone who works for a CNC OEM, it’s refreshing to see someone machining on something other than a Haas on YouTube. Makino makes a beast of a HMC.

5 year schooling and 19 years experience as a conventional machinist and that's only enough to understand what this guy is taking about.

I was watching this with subtitles and it said "we're gonna go in with the Harvi Ultra Hate Axe" and genuinely I love the idea of a product called that

Walter helical mills won the Boeing challenge in Ti on a Makino T2 machine! Kenna didn’t even come close!!

That was an amazingly beautiful procedure, in which a beautiful and technical part was created, while using beautiful equipment! 😉 😲Wow!! Great work fellas! Thank you for sharing your technique, skill and experience with my students, all of us here on YouTube and in effect, the whole World!! We know that you don’t have to share your process with us and I want you to know how appreciative I am and how amazed we are! I work in Career and Technical Education (CTE) where we teach Precision Machining as one of our many programs. We as educators have all agreed (and have unfortunately recognized) that it seems as if many Precision Machinists and CNC operators keep their experiences, lessons, discoveries, skill-set and wisdom to themselves for fear of losing their job. By keeping to themselves and never sharing, they are hurting themselves and slowing the progress in our industry. What they don’t realize is that more and more industries are in DIRE need of trained, skilled and certified CNC Machinists! As of January 2023 Precision Machinists/CNC Machinists are internationally in demand more than ever before! Check out this news article about the HUGE lack of CNC Machinists and educating High Schoolers to begin their path of filling those GREAT JOBS: https://wbur.fm/3w4tSAU Imagine if Bill Gates and Steve Jobs kept to themselves and never showed the world what they created in their garages. Imagine also, if Nikola Tesla and Thomas Edison were tight lipped, so much so that their discoveries died with them! We would definitely be a lot further behind, that’s for sure, as the world waited for someone else with similar experiences and skill-set made the same discoveries but actually shared them with the world this time. Thank you for setting a great example and for sharing your expertise!! Keep up the great work! 💪🏼
