Shoot'n The Poop #1 - End Mill Grinding Fixture

So, how about those End Mill Grinding Fixtures?
My apologies for the audio in some place.. my mic started clipping. Tried to fix best I could.

[@thelamb288]

I have worked for large companies and they used to collect all worn or damaged cutting tools and send them out for re-sharpening! You are NOT a cheap skate. Enjoy your videos much more than a lot of other channels. Cheers.

[@samrodian919]

The Lamb, No he's a tightwad lol

[@lifuranph.d.6607]

Yes, but then there’s no nominal size end mills after a total regrind. e.g. 1/4'' = . 2486'', 3/8'' = .3734'', etc.

[@mirek4357]

@@lifuranph.d.6607 They can be regrinded to specified diameter tho, I worked on Walter cnc grinders and most of the time the customers didnt care about the end dimensions so we usually took 0.2mm or 0.3mm from the diameter and from the face we took depending on damage of the mills So for regrinding I would rather send it to some company since it was really cheap to regrind couple of mills

[@chloehennessey6813]

I just like to listen to you talk, Tony. I wish my shop teacher spoke and used humor like you do while explaining. I’d listen more in class. I’ll be a junior in high school this coming school year.

[@pigtailsboy]

Introduce your shop teacher to the various KZbin production houses dealing in shop work then. If they can't adopt some of the techniques in class they can at least pass along these contacts as guides for their students.

[@eformance]

Does your grinder spin in the opposite direction because it's metric? ;-)

[@luminousfractal420]

[@jemijona]

Same as when you flush the toilet in Australia. The water spins the other way.

[@user-uk5bx1kz2k]

What I think it's only spindle motor connection issue. Metric grinders, as you call them, also have CW rotations. Maybe it's easier to work with grinder in a tight placement

[@Gottenhimfella]

Diamond (or CBN) wheels will load up much more quickly if used dry, which they're not intended for. Such wheels should ideally be trued as soon as the motor current indicates the wheel is loading up. If this is done, the wheel will last a lot longer than if you wait until glazing can be seen, because you will only need to give it a lick. After truing, you need to dress the wheel. The resinoid material which bonds the diamond particles needs taking back below the outer profile (the cutting corners) of those particles. This is so they can penetrate the work and deliver a free cutting action. Otherwise the stone will (again) load up much more quickly. Use a dressing stick one grade finer than the wheel's grit size. This will permit the stick's abrasive grains to penetrate into the gaps between the particles on the diamond wheel, and remove the binding material.

[@StefanGotteswinter]

When I regrind the front cutting edges I dont bother with secondary clearance and gashing - I just grind them with about 2...5° clearance to the center and to the back - They work very well but of course you cant plunge with them anymore. As I have a surface grinder now I might pick up that fixture too, would save me from use the single lip cutter grinder fot that purpose..

[@marceltimmers1290]

Hi mate. I found it interesting that, while you did not expect it, the wheel and fixture did quite nice. Rooting for the under dog? I don't know. But a fun fact never the less. Shooting the poop. The name reminds me of a patient I had. This person was so very constipated that when it was finally time to have a poop, this patient had no time to pull down the underpants, and sit down. As a result the whole back wall of the shower/toilet was sprayed from the ceiling to the ground. I had never seen something like it. Now that's what I call shooting the poop.

[@BrokenRRT]

As a respiratory therapist I was securing a patients airway during bathing time. I was on the right side of the bed in front of the ventilator and 2 nursed rolled the away from my direction. Suddenly the patient started farting and next thing you know sprayed the entire curtain next to me with 3 massive blast of poo. I just missed the line of fire but it was so explosive it was 5 feet up the curtain and literally moved the curtain. The nurses claim I screamed like a girl as I dove for behind the vent and cart. One of the most memorable code browns I have.

[@marceltimmers1290]

Hi mate. Moments in time, that only health professionals can appreciate, When you tell it to a "moggel" they only think it's gross, and often loose their appetite. Stories like this are most often spoken about during lunch time. I love it, and miss it. Thanks.

[@KennyRusso77]

I know this is an old video, but I'm trying to catch up on all the "old" subjects as I work my way through your library. And this one brought up a lot of memories of my days as an apprentice tool and due maker. Early in my training I spent a year just sharpening cutters. I learned to sharpen cutters of every shape and size, and we had all the equipment needed to sharpen them properly! Back then (mid 1980's) the injection mold industry in Grand Rapids, Michigan was just then getting into inserted fly cutters (carbide and ceramic) and things of that type, but all that new stuff was extremely expensive, so almost everything was still cut using fluted HHS and carbide cutters, which needed to be regularly sharpened. Your video bright back A LOT of memories of that for me (...and I'd just gotten over my PTSD, too)!!!

[@ifaistostenten5454]

I do mine carbide end mills with hand.. I use grind weel to make the face but all the others "cuts, angles etc" I make them manually. It is easy and very quick. Well, I use this process every day so, it may be easy for me. I am in die-mold businnes and the material I cut is 80% steel and stainless steel. So I can't affort to buy every day 4-5 end mills.

[@mikewelch8379]

This was both educational and entertaining. I have seen these fixtures many times but had no idea how they work. Thanks!

[@alainvaudou]

Hi ! your videos are awesome Tony. I'm a machinist myself but i did that for only about a year.

For those of you trying to read that list of KZbin machinist creators at about 0:13 (to see if you are on it??? I'm not.) Google Chrome has a method for stepping through a KZbin video frame by frame. You pause the video and use the angle bracket keys "" (actually the comma and period since you don't hold down the Shift key). In this case it will disclose that the list has been repeated several times to make the fast scroll last longer. (This may change the playback speed when you resume normal play, but that can be corrected by clicking on the gear at the lower right of the playback window.) And now ... back to actually watching the video.

Get some white sticks for grinding that carbide so they don’t glaze up too much. You really need some lube during the carbide grinding process but not for what you’re doing. Match the grit of the wheel to the white stick (240 stick for 240 wheel etc)

[@StefanGotteswinter]

After watching this video again, what kind of magic did you use to cut the carbide endmill? Did you have a proper diamond cutoff wheel?

[@ThisOldTony]

I used a diamond tile saw.. 115mm in an angle grinder. You could probably use a dremel diamond saw if you have one. Just nick the side of the end mill (cut through one flute and a bit into the core). A vise and sharp smack with a hammer will do the rest.

[@StefanGotteswinter]

I am suprised that the tile saw works on carbide, those seem to have very little diamond content - Have to try that :D Thanks!

[@ThisOldTony]

+Stefan Gotteswinter they don't have much but they do the trick. might not cut very many tiles after that though.

[@chrisduffy2737]

I once had a job running a CNC lathe at night all by myself. The day guy worked his ass off producing 93 stainless steel parts, taking no breaks nor lunch, sucking up to the boss when he came by (I know this, because he showed my how to run the machine). Best I could do was 84 and since I worked all alone I had no one to glad-hand! What to do? I figured by pushing the feed rate on the single large diameter steel drill used to remove most of the inside metal, I could make parts faster. So I doubled it. It worked, but the drill cutting edges wore out . So I rigged up a drill jig on a nearby surface grinder so I could quickly sharpen that lone drill while the CNC machine was running. Eventually, I increased the feed until I was in the realm of diminishing returns and settled on a happy medium. So for as long as that job ran, both day and night shift ran 93 parts apiece. The day guy pissed in a bottle behind the lathe and brown-bagged it, while I had plenty of time for breaks and could go to the dining area for lunch.
