[@freekgopher]

​​​@@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.

[@Quest4Blood]

Probably because quartz is not glass? This is cool, but they have distinctly different properties.

[@freekgopher]

@@Quest4Blood But glass can be shaped like this as well.

[@ZirbMonkey]

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.

[@TheBackyardChemist]

I think he mentioned it was "quartz" so it should be fused silica. I think tempering is not really applicable for that.

[@LandonN9]

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.

[@BenAtTheTube]

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.

[@Rock57811]

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.

[@BadGuyDennis]

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.

[@Rock57811]

​@@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.

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.

[@clockworkvanhellsing372]

Considering it must handle carbide and potentially some dimond dust, glass which is much "softer" should be no issue.

[@nealkrueger6097]

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.

[@pauldriscoll5010]

You guys are always pushing our trade further. So cool, amazing work you all do.

[@andrewreimisch5487]

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!

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.

[@verakoo6187]

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.

[@SimpleUser11]

@@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.

[@SimpleUser11]

@@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.

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.

[@trevorgoforth8963]

I love this idea!!!

[@Lily-gr1ct]

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

[@johncuthbert1888]

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.

[@okaformichael383]

This was entertaining. Keep it up guys.

[@houstonhines9434]

just the fact a glass endmill bit was made is astonishing of what that grinder is capable of!

[@ZXLMaster]

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.

[@Wayne_Nero]

Way cool!! I found you guys from GMG… nice shop !!

[@Schnatty4468]

WHAT IS THAT MELODY (bro is literally playing the hardest bangers)

[@glassgod85]

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

[@sergioalmazan7077]

[@GoingtoHecq]

Seeing them break was painful. I am sorry for the guy who made them. I appreciate your skills man.

[@russellzauner]

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.

[@adamhayes2528]

[@Leo99929]

You could try heating up the glass where you want it to crack, then quickly chilling it. That can often produce a clean break.

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)
