​​​@@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.

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.

Nice work Chris! Even if it didn’t cut, It’s fun to see what these machines are capable off!

[@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.

[@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]

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?

[@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.

[@tdg911]

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.

[@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.

[@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!

[@alt5494]

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.

[@k992-o6r]

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)

[@fmboss429]

A judicious application of heat on the score line, and then a little cold water.... SNAP!

[@VasilyBuilds]

You guys should try machining Jello with that one 😂

[@houstonhines9434]

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

[@Kolokotrones]

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.

[@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

[@mrayco]

I won't sacrifice this piece of art❤

[@Eluderatnight]

You can cut glas slow with a wet tile saw

[@SimpleUser11]

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.

[@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.

[@Gran0s085]

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

[@nikosvandenbroek246]

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

how to break glass? make a small "cut" with a knife or file. get another piece of glass. hear this piece of glass up until it's red hot (or just before it becomes liquid). PLACE this hot piece directly on the cut. you most likely now have a perfectly straight cut and 2 nice pieces of glass. now i learned this with glass tubes (glass blowing) so this might ... not work ... only 1 way to find out.

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.
