*THAT WOULD MAKE* a brilliant engineering trophy - you should set up a competition
EDIT: this was an unexpectedly popular idea
I love that idea! Lets do it
@@exchanginq5215 could you point me to the bit where I said they were engineers?
@@piccalillipit9211 Why should they make an engineering trophy and set up a competition for it?Why so specfic?
@@exchanginq5215 Dude you care WAY too much about this.
@@piccalillipit9211 It took us the same amount of time to type
Make an endmill out of wet oatmeal next!
Yep, at least oatmeal won't crack and break!
Oh c’mon, as a desk ornament that thing would be sick 🔥
If you've ever cleaned dried oatmeal out of a bowl you'd know that it's gotta be as hard as tool steel.
@@Yoggoth if you go low enough in temperature it may well crack and break.
make yourself dead with rope and a chair
The fact that you were able to shape that with out breaking was incredible 👊
It was a challege for sure glad you enjoyed it!
@@christophervillalpando1815I know you are set up for metal and the like, but if you have finer wheels, say what we call d400 to d600 resin bond up to like d1000 you could get some real fine edges. That would be a neat challenge. We do large scale glass CNC if you want some tips.
Probably because quartz is not glass? This is cool, but they have distinctly different properties.
@@Quest4Blood But glass can be shaped like this as well.
After you're done milling, send the glass to get Tempered. You'll give the edges the harness and toughness to withstand some higher mechanical abuse. This does require you to get a specific formula of glass.
I think he mentioned it was "quartz" so it should be fused silica. I think tempering is not really applicable for that.
you cannot temper glass.
@@chargehanger tempered glass is a widely used term to refer to glass with intentional internal stress
@@chargehanger you... literally can? you windshield is tempered glass thats why its so tough and able to take knicks with out shatterying
Hmm, sorry, I confused with tempering steel. Not the same process, but similar results :)@@avaavalon2467
Nice Idea, you guys could consider to put the endmill into a Pottasium-Salt bath to close the defects on the surface due to the production process to increase the strength of the amorphous structure. Additionally you could give it a view under a crossed polarizer to see if there are any mechanical forces on the structure due to the production process.
I'm not an expert so I don't know about the potassium salt. Nice you've pointed out. At the same time, I've also thinking about the polarizing inspection would be a good idea.
@@BadGuyDennis There is a nice video from "Applied Science" who explains how Gorilla Glas works, and he uses the potasissium salt method to show an experiment including measurements.
Nice work Chris! Even if it didn’t cut, It’s fun to see what these machines are capable off!
Chris, to cut the glass rod to length, you might try doing it like when cutting glass bottles. Basically, you score the glass at the length needed . The score depth should be roughly 1/8 th the diameter. Using two V blocks place the rod stock r v block and rotate to score the line with a new unused glass cutter .Note that if rod is not easily turned try using a light assembly grease.on the v blocks in a very thin coat. Then heat the glass in a hot water bath under 160° heat soaking for five minutes. The pull from hot water bath and apply ice to just the score while rolling the rod on the v blocks. . Safety notes proper PPE gear should be Eye protection minium of goggles,or safety glasses and facesheild , and gloves. I used to cut glass wine bottles necks this way for vases this way. Or you might try cutting it off with a abrasive media while submerged. I also made aquariums from glass blo k with a diamond hole saw with the block submerged under water. The water dampens the vibrations of the cutting tool and cools the material, thereby easing stress shattering from heat . The glass end mill mounted in a block of aluminum with a hole in the block to allowing the bit to fit into the block . A smaller hole in the bottom of the block to allow a high intensity led to be installed in the bottom to ligh up tbe end mill. Four groves in the top to allow a plexiglass cover to sheild the mill bit from physical contact.
That was what i was thinking it does work well on quite thick tube
or just use an angle grinder with a diamond cutting disk lmao
Or his giant grinder might have cut it
@@chrism4008this is the answer. Has a huge $500k+ piece of machinery that could easily cut it.
The heat method won't work on quartz because it's coefficient of thermal expansion is too low.
I'd have one of those Glass endmills just as a decoration, I love how crystal clear it is. Also, it is me or did Barry cut cheese with it as the video ended?
Yes he did. And ate it on a chip.
Barry is always cutting the cheese
Agreed!! @TitansofCNC, you guys should start making these as awesome decoration pieces! I don't care that it can't cut, I want one of these sitting on my office desk just because they look cool, and they'd be a great conversation piece.
No, I am sure the video showed it mashing cheese, not actually cutting cheese, although that seemed to be the intent! I think the speed and feed were way wrong, and the cheese was totally sticking to the glass so there was no usable cutting edge. At the right speeds, it should make nice shredded cheese.
Create a pedestal with an RGB LED in the base and put into a showcase. 😎
That helitronic must have one heck of a filtration system... Pretty cool to be able to take something so delicate and grind into an end mill.
Considering it must handle carbide and potentially some dimond dust, glass which is much "softer" should be no issue.
You guys are always pushing our trade further. So cool, amazing work you all do.
For my experience in "snapping" glass, as shown here, is that your hands were too far apart from the score line. Pressure was put too far away to create the necessary energy to finish the score into the material.
I always put my two thumbs right behind the score line and push away from my body to finish the cut. It has rarely failed me. Good Luck!
Finally someone thinking of expanding CNC machining to the bakery business.
Cool souvenir. Wooden stand and LED lighting at the end.
"I've never done this before so I googeld it"😂 What a beautifull world we live in
Great video, Chris! I appreciated the way you explained each process. I agree with others that the glass end mill would make a sweet lamp/art piece. 💎
The end result looks like a CNC competition trophy 🏆😂
A judicious application of heat on the score line, and then a little cold water.... SNAP!
You can cut glas slow with a wet tile saw
That thing looks incredible. i would buy it just by the looks of it.
A chopsaw with abrasive wheel is good for glass rod. Water jet also works well. Use a slow speed with either to avoid shock loading.
By far one of the coolest things I've seen made in a machine. Great video Chris!
Try sapphire or cubic zirconia. The are much harder (9 on Moch scale for sapphire and 8 for cubic zirconia and only 7 for glass) and also stronger. Not sure if it will cut metal, but may be it will work for wood.
Lol pretty sure it would be impossible to get those in bar stock, gems don't exactly come out of the earth round or at size. Most are smaller than 1x1mm when they are mined.
Not to mention if a sapphire of that size even existed it would be worth billions.
Biggest in the world is only 9.9 ounces and fits in the palm of the hand.
@@verakoo6187I`m talking about lab-grown sapphires. They are produced in different sizes. Cubic zirconia is also lab-grown material. As for the natural gems, there are a lot of stones much bigger then 1x1 mm. I`m professional jeweller with 15 years of experience, so i know what i`m talkin about.
@@verakoo6187 Also, natural stones don`t fit wor this task due to a lot of flaws in their structure. Even loupe-clean stones have a lot of stresses in their crystallic structure. Lab-grown stones do not have this problem. Also, it is possible to grow monocrystal stone which will have even higher quality.
Anyway i think they will be too brittle for this task.
The "Tactical Acquisition" had me dying laughing. Heck of a video. Even though the tool failed, you succeeded (in making a tool that failed).
This show never disappoints
Remember drilling a hole in a bottle for a water bong, an elderly carpenter took it, submerged in a bucket of water just over the where the hole would be then drilling it perfectly with a masonry bit. Was good to watch.
Dang Chris that is INSANE! Good work!
i really like the tactical acquisition of the diamond file.....
I'm a glass artist. Quartz makes sense for the material used because of just how much stronger it is compared to soda lime or even borosilicate, but yeah score and cutting a 1 inch rod would be very difficult. You've got diamond wheels, so you'd be able to set up cutting fairly easily. A simple tile saw will do the trick but make sure when cutting glass use plenty of water on the blades and material. Diamond wheels and laps are used to get perfect edges on glass, though if cutting go real slow and prepare for a little bit of chip out that'll be very sharp.
The other option which isn't as consistent as a cut, would be to do the same score, not super deep but 1/4 to 1/3 the way around the rod, heat up a thinner glass rod and glob it half way on the end of the score. This'll create some thermal shock to break it.
Potentially annealing the quartz might have made it stronger, but honestly I'd be surprised if there was a huge difference. Rod tends to come pre-annealed and quartz is so hardy the actual stresses put onto glass by grinding and shaping are minimal. Glass is fantastic for compressive strength. You could tighten down that rod in the chuck probably as strong as a regular carbide tip, but it's sheer strength is very low. I think if gone slow enough it could probably drill through copper or brass, but could not face anything
Love the channel! You're GODS of CNC!!!
The best way to have broken it is to apply your score mark then put it in the chuck. Spin at a slow speed and apply heat with the tip pf a map gas flame just off the score mark. It will crack along that line and break off somewhat evenly
That was a work of art, no Q.
production quality is on point!! 💪
The point of filing the glass isn't to make it thinner (though you can simply saw through it with a diamond saw).
The idea is to produce a crack which acts as a stress concentrator.
So you want as sharp a notch as possible.
That typically means a very thin scratch.
You'll wanna get This old Tony in, I've seen him do that snapping thing on 1 inch cold rolled steel.
lol this old tony has some crazy skill
Use a tile or rock cutting saw, slow heavy grinding rotations. Glass also needs to be annealed to avoid residual internal stresses.
Alternately, you could use a breaking die (since you're in a machine shop) making a couple collars that fit the glass rod closely and tightly together; once the glass rod is into dies, just shift it a minute amount and it should shear. I'd never think to do it this way but it might be convenient for you if you need to make a bunch of blanks fast; predictably without a ton of waste.
The 1" diameter rod realistically needs a diamond cutoff blade. Also a full set of these, 1/8" -1" would be pretty cool as a shelf art thing with a nice aluminum display case.
Hell i would buy one just to have it to show 😂 Chris that is badass that you could even grind that out of glass. Thanks guys for sharing
1:27 Nailed that 5" to the thou! Haha nice
It would make a good permotin gift. Like 5 years with the company type thing. Pretty cool thanks for sharing 👍
FINALLY! something in my field.
Shop art is amazing!
I actually got excited when he brought the wood in. I was not disappointed 😂😂😂
I won't sacrifice this piece of art❤
I call that a success not a failure the mission was to make the endmill which it was incredible piece!!!
Heck just as a desk conversation piece...those would sell awesome...especially if in a polished metal base, with the Titans logo of course!
So, could you grind 48tpi threads on a glass rod?
I'm planning on trying it in my shop one of these days...
Man, I want to buy one of theese, it'll make a perfect gift for a machinist!
now this is awesome!
What many do not realize is that the crossectional area of a 1 inch diameter rod is close to seven times that of a 0.5 inch diameter rod.
This is perfect. I always said that the problem woth endmills is their durability. You guys solved that issue!
Maybe you can try upgrading to jello for the next one?
Semper fi brother
This was entertaining. Keep it up guys.
I agree. Would make a great trophy or gift. Cool video Chris 💪
just the fact a glass endmill bit was made is astonishing of what that grinder is capable of!
Can you lot make an unpickable lock please.
Lock picking seems to mostly rely on manufacturing tolerances.
I bey you could make a great lock.
I love this idea!!!
Seeing them break was painful. I am sorry for the guy who made them. I appreciate your skills man.
next time you gotta cut thick rod, you're gonna want a score line all around, hit it with a blowtorch and throw it in ice water once it's hot.
(credentials: worked in glass manufacturing, we always just used fuel alcohol and a lighter but a blowtorch should work just the same)
You could try heating up the glass where you want it to crack, then quickly chilling it. That can often produce a clean break.
I’m a tool grinder by trade and I like your stuff. We on the grind literally, and figuratively 😎🔥
Way cool!! I found you guys from GMG… nice shop !!
I will buy one looks beautiful!
Btw for those curious about how it performs, this is part of a video and it’s link in between the channel and title of the short, not super obvious, but CZcams does that if you make a short out of a full video. Alternatively: czcams.com/video/qHL9zuCE9Ys/video.htmlsi=JyoHu0So3_q03bb0
It's astounding you achieve these feats using the imperial measurement system.
WHAT IS THAT MELODY (bro is literally playing the hardest bangers)
I think if glass were a viable option we would have utilized it by now but great beautiful piece! I also agree that 1” would be a great trophy design
Do you think you could make an endmill out of high entropy alloy? (Breaking Taps did a video about the material about a year ago)
It would look cool as a display artwork for front of shop to showcase your skills or at an expo type thing. Especially if you had a bunch of different sizes.
How did you tighten it in the chuck? Just on bare metal?
I would pay for a glass end mill. The tool of LIFE!!!
You can heat the glass and hit it with some cold water on the score mark to make a nice cut. Never tried with rods that big but I think it should do the trick.
O melhor conteúdo 👍🏻
For cutting a rod of glass that size and bigger, we usually use a glass cutter. Basically it’s a verry small round rotating diamond blade and it makes a shallow but clean score in the glass, after that a light tap with a small hammer or anything else it brakes quite cleanly
I honestly for some reason had way too much hope for this , I was so sad when it busted. I use a mill at work all the time. Nothing this fancy. But this is a straight work of art. I would buy one.
It's so bizarre but I work with inch diameter quartz rods exactly like that one every day. We have a special diamond wheel for cutting them. You send one my way and I'd be happy to cut it to size for you. Love your content.
I think I saw some chipped edges on the glass endmill, if so could you encase the stock in something like a wax to support the edges and use a slower feed?
that is amazing
So cool!
That glass end mill on a beautiful piece of wood with a hidden little LED light will make a beautiful ornament or trophy. Please let me be the first to win just for the idea.😊
i wounder how it would do in machining foam or machining wax
looks really nice, well machined. I wonder how it would fair with foam?
You could probably use the glass endmill in Teflon or some soft plastic like Delrin
Glass is different than quartz. But it was the right choice to use quartz because it should be consistent with the crystalline structure
Glass and quartz are both silicon dioxide, though glass usually has other compounds so it melts at a lower temperature
Wow cutting some major cheese in this one 😎 what a cool video Chris!!
While I don't think engineers are chomping at the bit for glass endmills, I think there's some interesting stuff about glass that might be worth exploring in a future video. Maybe if Corning reaches out for a sponsorship?
1:35 🤣🤣🤣 so sneaky
You guys should try machining Jello with that one 😂
Since i m working from last 9 years as cnc machine operater i never seen a glass endmill 😂
Good job
I’ve probably got some 1” rod if you really wanna do a larger piece. If not we could get some in and cut it to whatever length you wanted.
Just curious why you didn't use the grinder to cut the 1 inch glass blank.
Well........they look really cool!
Awesome video Chris! A diamond file tactically acquired from Jessie! 😂
OMG NICE
could you use a 4th axis and engrave the one inch before trying to break it?
I'm here for the entertainment. Not disappointed at all.
If you could apply hardness attributes from a prins Ruperts drop into any glass part, that would be awesome.
I really thought Barry would at least try to cut butter with it. I want to see Mastercam Dynamic motion cut butter with the glass End Mill
Ruby rod of different sizes was used in laser machine. The hardness of ruby will make a nice drill bit or just an expensive trophy.
I wonder if transparent aluminum is stronger or weaker than that glass
Or diamond or quartz crystal good like trying to find diamond long enough
Been in float glass mfg for 10 years. Heat it around 80C and make your score. Get some sort of triangle like a piece of angle iron, point up on table, hold the score upward and center the rod score on the point of the triangle. Doesn’t even have to be a triangle, could use a cylindrical object. Just center the score upward.
