Cutting a Keyway with the Horizontal Milling Machine - Old School Still Making Money

[Music] hello welcome to topper machine i'm josh topper so today's job is to cut a key way in a 2 and 7 16 inch shaft we got to cut a 5 8 key way 5 16 of an inch deep and we're going to do it on the cincinnati number two horizontal mill now if you remember back a while i cut a deep groove in a piece of bar stock on the la or the mill here and these two vices are indicated in perfectly to the spindle and they don't leave this mill really i for the most part it just does long cuts like that and i just leave these vices set up indicated in all the time and we're going to go ahead and put the bar stock in the vise and then switch out from our three-quarter inch wide cutter here to a 5 8 cutter and here is the cutter we're going to be using it's a 5 inch diameter 5 8 wide with an inch and a quarter bore when i bought this cincinnati mill quite a few years ago i've sourced every cutter i could possibly find and as i wear them out i just replace them but i've got bins full of of horizontal cutters for this machine and different arbors and everything so i'm well equipped with it but let's go ahead and tear down everything and get her switched over to the to this cutter so do [Applause] all right so we got our cutter in there we got our arbor support on everything's tightened down i'll clean up our cutter that i took out and put it away and then i'll bring the shaft over and we'll get the shaft in there and indicate in off the shaft and start cutting our keyway okay first thing we're going to do is run the table all the way to the end so i know where i'm at [Applause] and according to the drawing i'm going actually about 14 000 deeper than what is recommended by the machinery handbook so we'll uh cut this a little bit deeper than than the book says so i'm just going to set the indicator up here just because i want to double check and just make sure i got it in the in there flat and it for the application it's not super critical but we'll just see where we're at [Applause] and put our indicator at zero actually let me adjust that [Applause] a little more up so we're about mid-range of our travel okay let's see where we're at [Applause] and we're a little off i might have to clamp my bar and pull it down on the other end i was struggling there to get it in the vise [Applause] so i'll go ahead and grab a clamp and put a clamp over here to pull it down and then reclamp it in the vise [Applause] [Applause] [Applause] [Applause] [Applause] all right so i'll go ahead and release this vice [Applause] and yeah look at that pulled it right down a little more on there just to make sure she's tight [Applause] all right i don't know how much glare you guys are seeing there [Applause] about five thousandths in that five thousands range i guess i can live with that let's uh set up the indicator the other direction and just check it perpendicular to the spindle [Applause] all right well here's hoping nothing moved on me except the camera i hit the camera with the tripod with the table let me move this back over get out of the way all right now hopefully you can see that good but i didn't see any movement yeah a little bit there so i may want to try taking that out and that's just a matter of loosening up the one vise and just tap it over so i think i'm gonna do that just to get this as true as possible [Applause] that i can live with [Applause] so i don't know how well you can see this but i got this piece of paper here and i just measured it it's three thousandths this is my feeler gauge for setting my my cutter so let's go ahead and bring the cutter in and touch off okay so we'll go ahead and start our spindle up and i'll bring the table up to the cutter actually i need to run it out a little because i don't want to hit okay now [Applause] i'll take my little paper feeler gauge here [Applause] we just kind of hold it there lightly [Music] when it grabs it that's three thousand so we'll set our readout zero our readout and uh turn it in the three thousandths zero our readout again and now we're ready to go in halfway to our center [Applause] you know i can be an idiot sometimes the thing we stop and look before doing anything i gotta go halfway of my cutter now which is three point point 0.3125 close enough zero it now we'll go in our 1.219 which is half of our 437 2.437 [Applause] all right and lock her down now our cutter is centered i'll go ahead and run it out to the end touch it off take it off the end and then make the start the cut [Applause] and again this is another good spot to use our paper feeler gauge so i'll just hand crank it in until it looks close [Applause] and there we are [Applause] throw it in three thousandths should touch yep just started touching [Applause] all right so i'll run it off the end here i'll watch though for center and i mean the length of this keyway isn't critical but and now what i'm going to do is a full depth of cut so this keyway will be the full depth so my customer specs calls for a 2.07 0 finish so that's 366 thousandths that i need to go in i'm going to do this in one pass so it's nice and clean [Applause] three sixty [Applause] six and then lock her in and did she move no not too bad then we'll go ahead and turn the oil on and engage the feed okay we got our oil turned on dribbling nicely on the cutter there [Applause] sorry about that i forgot to hit record when it started to cut and i'm cutting at an inch and three quarter a minute and don't forget your support bearing make sure you put oil in that i already did that and we're all good but [Applause] [Music] [Applause] be [Applause] [Music] [Applause] [Applause] [Applause] [Music] [Applause] so [Applause] so [Applause] [Music] [Applause] so [Music] [Applause] so [Music] [Applause] [Music] [Applause] [Music] [Applause] [Music] [Applause] [Applause] [Applause] all right we're creeping up on our 16 inches and that's 16 inches to the center of the cutter [Applause] and when i get there i'll just pop it out of gear crank the table down and shut her down 16 inches three thousandths three thousand seven tenths that's pretty pretty good [Applause] i'll run this thing to the end we'll clean it up and then we'll measure our keyway see how it looks all right well there it is now i've got my gauge blocks it's all cleaned up and this is 500 or 626 thou and it won't it'll just barely start in a couple spots won't go at all there there here is 625 and the specs on the the keyway calls for minus zero plus one so it's probably actually 625.5 because this fits in the 625 fits but the 626 does not so i say we're pretty good okay now i'm measuring my depth the drawing called for 2.070 finished and we are 2.0 2.0 70 right on uh that's nice thing with these horizontal milling cutters they cut so accurate if you set them up correctly so you know my motto get it done right the first time and i had one shot at this to cut this keyway and it came out absolutely perfect and you know with these horizontal mills i've just had so much um good luck or um accuracy with them they've just been incredible machines and and absolutely love them been running them my whole whole career the last 20 years and just love everything about them i probably don't know everything there is to know but i i do pretty well um and this this is a good example of of done right the first time so this was supposed to be a four shaft job it's a debarker that there's a whole bunch of work that gets done to this shaft yet after this a bunch of stuff gets welded to it those stars that i cut out on the on the torch table that's another piece of this job it's there's a lot to this so um there was supposed to be four of them the cost of material went insane and the customers just replacing the one that broke um they always have a set of four on hand the the drive and the two three driven this is a drive they broke a drive so they're gonna they replace that one with their spare this is the a back a replacement for the spare and we're probably gonna be making the other three coming up the next few months depending on how things go so i'm looking forward to that too and playing with the torch table some more on that job i got a couple ideas and making some modifications of that as we go so with that check out my store frontier account pick up some cool shirts for yourselves and until next time get out in your shop and get it done right the first time [Music]
