hi folks we have found it the microscope that should not exist it's incredibly useful incredibly easy to use and it is cheap the whole thing with lights and the built-in TV screen 000 bucks so if you if you use cutting tools run a machine shop I highly encourage you to pick one of these up and let's walk through some of the reasons we use it and some of the modifications and things that we've done to help minimize the Chinese ium nature of this thing and turn it into an even more useful tool no question the most common thing we use it for end mills and cutting tools so we have a 0/00 end mill here I think it's two flutes we're gonna use this tool it's really helpful to try to see what the flute condition is the first major modification that we made is we 0d printed this fixture it allows us to hold different diameter end mills at two different angles and rotate them will put the cad model for this up on the NYC cnc website so download it print your own you don't have a printer you can have it printed online we normally just use it real time in person but we're gonna hit the record button to record everything we're doing here to the SD card which is 0000 by 0000 so if you have experience with microscopes you know they can be really particular or difficult or fussy with a bunch of things the focal length getting the image that you're trying to see the three-dimensional nature and depth of the tool the focal length on a traditional binocular style like this one everybody has their own different IRA leaf and so we've used microscopes for years and this is like a breath of fresh air I put the tool on there right away we have it in focus they do have this large focus ring you can adjust the fine focus on and then there's a digital zoom obviously it's just a digital zoom so it's cheating but it actually still helps so here we'll jump from the normal range of 0x0 to two-and-a-half three three-and-a-half all the way up to five and you still have a really good decent view i can clearly see that those are two flutes i can get a pretty good idea of the flute and condition and a nice 0-dimensional view the other thing we can do is zoom back out and lower the microscope down to get a proper zoom in to lower down and here it can be helpful to rotate our fixture so that it's more easily pointed at one of the lights that we have and again that's really a very helpful and acceptable image quality especially for the price point you can see we have some debris on the tool there is only one thing you want to use to get that stuff off there and clean the tool it's the old bedroom wall poster putty stuff we'll put a link for all this stuff in the NYC CNC page but that is the way you to clean off your end mills and not damage them does a really good job of getting lint or debris or dust off there you can't use your fingers we found this out from the spur onei your skin cells will just flake right off especially at this high resolution we just bought some one millimeter drills there's three of them in there it's too small to rotate it in our fixture so this time I'll just hold it by hand and again this is where other microscopes really fail I found they're incredibly sensitive to a lack of vocal range so something's always out of focus or you don't have a good three dimensional depth and here really not a problem to hold it steady enough rotate it in your fingers and get an idea of again what the cutting flute looks like the edge quality the condition of the drill we use these 00 degree - flute or for fleet mill drills can use them to spot drill chamfer and great etcetera but if you chip any of the flute point off the height will be wrong and thus the tool will be sure and you'll generally make a larger chamfer than you intend it to because there's a flat point spot on it so you take that lay it in our fixture and you can easily get a very clear view in this case of where the tip of that tool has chipped off or been broken in fact right there is where the carbide fractured we had some premature tap failure on our fixture plates and it was bothering me so we sent a video and photo and email to the supplier and it was awesome to have really good high quality video and photos to help them understand what may be going on so again same thing just hand holding this tap and you got a really good image and three-dimensional view of how that tap failed and here's a screenshot of one of the PDFs from Sandvik that has some really good information on how to analyze insert failure to failure coding failure kind of read the tea leaves per se and on that note we use sandbag drills to drill the holes for our fixture plates and it's a insert tip style drill so there's a soft body that holds this tip and we get a pretty specific tool like our whole life out of this tip which we care a lot about because we'll drill twenty to thirty thousand holes a month and these tips are somewhere between eighty and a hundred bucks so the same thing we can use I like to use one of these machinist tool makers vices we've got holes a different diameter then I'll let that insert hold itself up straight up and down quite easily a quick focus and here you can see we've got a minor amount of edge where there but it's the other side of that insert where we had kind of a critical failure where that failure occurs and in the type of failure that is is actually really important either to you figuring out the problem or your tooling rep figuring out the problem and whether it's adjusting your speeds and feeds the rigidity the workpiece service foot for a minute feed rate all that stuff really cool and lastly just in case it wasn't clear just how much you can zoom in with this I thought it would show a postage stamp and a penny so there's the year 0000 on that penny but now if we zoom in a little optically by going closer you can see there and then again we can use the digital zoom if that's helpful same thing on postage stamps should be pretty easy to see the printing dpi to see how the postage stamps are actually printed it should be kind of cool I'm guessing these are CMYK printed anybody know actually are they RGB or CMYK but there you can see the actual printing colors on the stamp paper it's pretty cool so again we've tried a bunch of different microscopes including some ones that were multiple times more expensive than this if you get one of these again you're gonna want to print some sort of a fixture block or have a way to hold whatever you're trying to look at steady or rotate the base or roll the object we've actually found the filled lights that are included with this are okay but having either additional lights or lights with diffusers can also be something that really helps as well as reduce potential glare and then lastly we have not modified this on its base but that's probably the next thing I'll consider doing we may move it either onto a giant Noga arm which lets us move it around quite flexibly and rigidly or I'll move it over on to this other microscopes traditional base it's probably like a 00 pound weighted base that allows us a much greater range of motion as well as to slide it out of the way when we don't want it now but the basis is pretty rinky-dinky but it hasn't really been a problem we all use these on a pretty daily basis and this microscope by far has been the one that makes us smile because we really don't mind trying to quickly look at the edge of a flute of a tool to see if something is chipped heck we can even look at the feed-forward lines like we were doing in another Wednesday widget trying to understand the inch per tooth feed rate of an end mill and what that means in terms of surface finish try to hold it in line so really no problem at all in fact let me try to zoom a little closer on that yeah no problem at all seeing the feed-forward or scalloped lines of an end mill on that part so again what you're gonna get out of this that you don't get out of the $00 or cheaper USB microscopes is actually pretty decent stereo or 0-dimensional view other digital microscopes that we have tried have had really bad or poor refresh rates they're very sensitive to the lighting and thus there's a lag which makes it very awkward to use and rotate the fact that this has a built-in display frankly is pretty handy what it's not good for is it's not the kind of microscope you're gonna want to work under especially for extended periods of time so if you're doing PCB solder work or deburring work you might be able to use this one especially if you put it on a better baser amount but probably going to want to step up to wanted like the am scopes or trinocular style microscopes but those can easily get to the one to three thousand dollar price point so so again this is an awesome fine anyone out there running a machine shop I would highly suggest it and if you can't afford this go pick up one of the like six dollar 00 X loops not the same as this but it's still incredibly helpful in the shop hope you folks learn something hope you enjoyed take care
