Riten Industries Face Driver, Turning Between Centers

[Music] thank you [Music] hey guys welcome back to the shop so today we have a couple of the fellows from written Industries here we have Thomas and Kent from written there's Thomas and we also have Chris here he is from Coastal manufacturing Solutions Chris is actually providing a couple of the tools that we're using today on our miltronics CNC lathe to do this operation but what we want to share with you is I have one of the new or new to me anyway the face Driving Systems for our miltronic CNC lathe and I got it set up on the on the lathe here and the Fells from written Industries come down here and they are helping me to make sure that I've got it set up properly on the machine and that we're we're actually you know I understand how it's used and that it's set up properly and we're doing some test Cuts over here to make sure everything is is good to go this is a brand new tool to me that I have never used before so face driving technology is new to me I know the old school way of turning between centers using a laid dog but this type of system right here is uh is pretty fascinating for me since it's new but it's a really great tool to uh to use for especially like high manufacturing high quality manufacturing you know production runs turn in between centers so that you can turn a shaft or a part from end to end without the need of a second operation so we've got it set up in the miltronics I'm going to show you the component parts that we have for this we have it set up show you what it consists of and we got a couple other tools here that we're going to talk about and then we actually have some shafts that we're running and we'll get some video of it in use and showing the the face driving tool in operation and how we're going to be using it so I'm going to come over here to the lathe now and show you what we've got going on and show you the components from written industries that we're using so this is the face driver right here and then we also have a spring-loaded center here as well this one is a four Morse taper for our tail stock and the reason why we're using a spring-loaded center is because we have a manually operated tail stock for the lathe here they have other types of centers that will be used for machines that have automatic tail stocks that you use the machine to set the controller we'll talk a little bit more about that but so the uh the system that I have this is a type 43 we'll take a look in the catalog so you can see they make these in a wide range of sizes so it depends on your application uh what diameter the material that you're going to be turning what type of material the length of the material and all that they can help you set up the proper size tools that you need for your machine for your CNC lathe but this kit here consists of the adapter plate for the uh for the spindle nodes that we have a a15 I believe is the is the size that I have all right then it comes with the spindle nose here with the center it has a center point in there and then we have mine comes with the three Drive pins in here okay they have them depending on what type we have you have a five pin six pin and different sizes here so we already have all this set up you've got to get this installed you have to indicate it and get it running true before you use it that's a very important step which I've already done foreign [Music] of course we got our tail stock tail stock spring-loaded Center and you can see these different color Rings here we have a red green and a yellow that is so that you can get the right amount of pressure applied with the tail stock using the handle there and the right in the correct range of pressure so that it it uh pull pushes in on these dry pins here all right and we'll talk a little bit more about that they have got another tool here that they brought with them so that we can actually set it up on the tail stock here and and actually see the amount of pressure the force should I say that we're applying on the center so let's go over there to the bench and check out that pressure gauge all right so here is uh here's their gauge that they that they keep with them and they take with them to whenever they're helping the customers set up these face drivers and make sure that the right amount of pressure is applied to the tail stock because you do have to have a certain amount of pounds of force pushing on your work piece into the drive pins so this is just a really cool tool that they can set up you've got a couple of Morse taper adapters in there you have a straight adapter in there and you can put this in your tail stock and you you can use this as a way to measure the pounds of force on that and that's what we did earlier we had that set up and it was a good way of using this because of you manually tightening up the tail stock we went to a thousand pounds of force and then 1500 in 2000 and that way we could get a good feel when we're tightening up the tail stock there using our spring loaded Center making sure that we actually have the right amount of force on that so you guys invest in in one of the written Industries face drivers they will come to your facility and help you get it set up make sure that the tail stock is applying the right amount of force to to use this system okay so what we have is a hydraulic pressure gauge here installed in the tail stock and what we're doing is that we're going to apply some pressure to the work piece we're going to use this and what this is going to do is show the work piece being pushed into the drive pins here and the first time we're going to go up to a thousand on the pressure gauge and we'll take the work piece out and then measure the depth of the engagement of the dry pins to see how deep they are and then we're going to set it back in there and we'll probably go up to about 15 or 1600 and then check it and check our depth there so you want to go ahead and run her in there all right so that's just using the uh the manual force on the tail stock hand wheel there and we've got a thousand now what is this is this a thousand uh pounds of force okay and then we'll take it out and we're going to check our depth of the uh the drive pins there so we just removed the work piece this is uh being applied with a thousand pounds of force you can see the three marks there from our drop pins and I don't think this is going to be deep enough so we're going to go back in there we'll apply more pressure and then we're actually going to see if we can measure the depth of the marks from the dry pins all right we got our work piece back in there we're going to apply a little more pressure to the tail stock quill again we're going to take this one up to where we're going to go 15. 1500. you can see that it's really taking some force on the hand wheel to get it there all right 15 so we're going to pull it back out and check our witness marks there from the dry pins all right so we've swapped it around and we're going to go up to 2 000 pounds of force this time yeah do it but it's getting pretty pretty tight isn't it it is okay so there's our 2 000 pounds so we're doing we're gonna do the same thing as uh just visually check our Drive pin depth there on our witness marks all right so here's the here's the end that we just applied uh 2 000 pounds of force to and you can see the three witness marks there and that looks about right where it should be on the engagement of the drive pins and then once you actually make the first pass across the work piece with the tool these are going to be even deeper than that and and should have proper engagement for the Turning process there now this is a sample that they brought with them so that we could just share this is a just one example of a component that you can machine using the uh the face driver tool okay so this component here now this was made on a lathe that has live tooling and what they were showing is that you can utilize that face driving system to index it to be if you want to come in here and do like they did they've got these flutes machined in here okay but just a really good example of taking apart and machining it from one end to the other in one operation and you can turn multiple directions when your machine and parts using this but the important thing to remember is that when you when you make your very first cut with your work piece you need to cut a to the spindle because that helps seat the drive dogs in the material and then once you do that then you can make you can turn each Direction there all right but pretty cool example of one of the one of the parts that you can make it's really it's really helpful for many Industries out there especially in the automotive industry if you ever look at parts that go into automobile maybe different axles and things like that if you look at the end of the shaft and you see those those lines that are pressed into the face that's because it was turned on a face driver system like from written Industries so as I had mentioned they make these face driving Tools in many different sizes so it really depends on your application so if this is something that you're interested in if you will contact written Industries they will help you size up the the proper tooling that you need for your needs they make them into various sizes of spindle sizes including Morse taper and straight shank as well and we have we're running the type 43 so that gives you kind of the uh the the range but you can you can get these guys in many different sizes there's a lot of different sizes here I'm not going to go over all that but basically if you can get with them and tell them the type of material the length and your machine they can set you up with the proper parts that you need one other interesting thing that I was going to point out we can do with ours is our flange Mount there we can actually take that and go to our manual lathe if we want to and Chuck this up in a Chuck or you can you can bore soft Jaws however you want to Chuck it in your three or four jaw and you can actually run this in your manual lathe as well so that's pretty exciting and I look forward to being able to do that later on in our manual Aid there so these are the shafts that we're running right here all right that's a that's a finished shaft from end to end and these are half 28 threads on this end and we have just different diameters that we've cut in there and so this is our sample part that we're going to be Machining here using the written Industries face driving tool so we'll uh we'll set up another piece and get going on that I did want to touch briefly on their life center repair as well so this is a live Center that I had that had a burned up spindle nose on the end of it the center nose was burned up and I sent this to them they gave me a quote I had them rebuild that and as long as your your life center is if your shell here is in good condition they'll replace the uh the spindle the bearings the grease and the seals and that kind of stuff or and if you need to they'll they will re-grind it there as well so this is one that I just recently got back from them I love these types of Life centers here with the extended nose they're extremely helpful on the lathe when you're getting into your small diameter so keep that in mind if you got some bad life centers contact them and they will hook you up and repair your life centers for you they will repair any brand of Life Center it doesn't have to be the written Industries brand so if you have one of their competitor brands that are damaged it needs to repair send it to them they will give you a quote on repairing these and I believe if you decide that you don't want to repair it they will give you a credit towards the purchase of one of their brand new life centers this is a couple of the pins so this is the center for the uh the face driver right there that's going to be your Center and then these are what the drive pins look like for mine right here okay so let's go over there and get a shaft installed and see this thing in operation all right we're going to get another shaft set up in here I've finally got this thing set up and we're we're making some good chips and a good part there I did want to point out that uh Chris had brought he's got a couple tools that we're running so one of them is the Carmex threading tool I believe so that's this guy right here that's what we're going to use for doing our threading and then the Turning tool is the uh the permit brand and uh it's the dnmg 300 series I believe is the that's the insert that we're running right there so we're going to use this to turn it and then we'll use the Carmex threading tool to do the threading there all right so let's get one loaded up so what we're running here is some two inch diameter 4140 it's been pre-faced and centered on the ends by the way so we already did that all right so this the center on the face driver is spring loaded so as you apply pressure it's going to be pushing that Center in okay and then what what I want to do is actually get it installed and we'll take it back out so you guys can see we can see the end of the shaft in the uh the witness marks on there that's what you have to do is get a feel for the visual reference of proper engagement on these work pieces because you got to have enough uh pressure against it to be able to drive it so I just hang it on the spring-loaded center here on the on the face driver side and then hold it up I'm going to reach around you on the back of the tail stock and bring this in just gently so I don't stab the end of the shaft with the point all right all right so I want you guys to see right here I'm going to start cranking the handle the hand wheel on the the tail stock and we're going to push it into the drive pins all right so now they're engaged we're going to come back down here to the spring loaded Center so you can see how much force that we're applying okay so on our live Center side as I said this is a spring-loaded center we have this three ring color gauge here that helps indicate the foot pounds of force that you're applying to the work piece so if we back you out here we've got this little chart that you can reference and it shows the yellow green and orange reddish color Rings that's on the the live Center there and it shows the pounds of force that you're applying in a size range right there so on our work piece we're going to be we're going to be working right up to where the green and the the red meat and it depends on the size of the Morse taper that you're running there as well we're running a number four Morse taper so we're going to be so 1350 to around 24.70 pounds of force that we're applying to our work piece and that's where I was showing earlier that hydraulic pressure gauge that we had set up in the tail stock there and we were actually able to put that pressure range on there and take the work piece out and be able to visually look at the the witness marks on the ends from the dry pins to know that we're actually applying the right amount of force and you got to get this right because you got to have for one you got to have enough pressure so it doesn't spin but also if you have too much pressure you can cause damage to the center the headstock or start warping your work piece depending on the diameter of that all right so let's go ahead and get this guy tightened up so you can see what I'm talking about here I'm going to start cranking in on the handle and you'll see this moving all right so now we're getting into the green shade and I'm going to come up just to where it starts touching the red so right about there okay and then once you have it have it there we'll go ahead and we'll lock the quill in and from there we're ready to turn and as I said before you got to start your first cut always needs to start and go towards the face driver or towards the spindle so that it seats the drive pins in there all right I'm going to go ahead and just take this guy out so you guys can see the witness marks there and we're going to use that as a visual reference and I'll get you guys out here so you can see it but there's our three witness marks on the end of the shaft there all right guys so this is the end of the shaft here that we just pulled out where we just tightened up and we pulled it out so that you can see the witness marks there from the three dry pins and what you want on this is three to five thousands of Engagement there whenever you apply the the pressure to it so if you can come in here and uh catch that with your fingernail that she that should be about right and once you start making your first cut on that it's really going to seat Well into those dry pins and you're going to have a more pronounced Mark there at that point so this is looking good right where it's at there we're going to go ahead and put it back in the lathe so that we can start making our cuts all right guys let's get her closed up and start our first Cuts now I am going to try to get some better video of this after this first Shaft right here but we'll just get this going because what I'd like to do is actually make we're going to make our first pass on it and I'm going to pull this back out so that we can visually look at your witness marks on this side that's going to be our first cut with this Mark on this side is the ones I just showed you okay without it being cut yet so we'll close this guy up and hit cycle start our program is proven out so we should be ready to go sorry about that glare I know it's coming off the Skylight there a little tricky to get your shots outside of the machine just because of the glare there [Music] [Music] all right I'm going to stop that all right got our feet hole all the way down to zero so I'm going to halts and stop it I'm just going to go ahead and exit out of that and let's take it out so that we can actually see that uh the witness marks for that first pass there all right so here's a little better look at the end of the shaft so this is after making the uh the first pass across it that's just a roughing pass by the way but making that first pass it helps seed it into the dry pins there and you can kind of see it you can see them a little better and you can definitely catch them with your fingernail all right and if we flip it over this is the side that we uh you know applied the pressure to without taking the cut and you can see they're not it's not fully seated so it's just an important step to make Whenever you set your work piece up that you always make that first cut against the um the face driver to get it to get it seated properly okay all right we're back in the machine we're back to doing some cutting did want to point out this is material we're using is two inch so it's a little larger than what we really needed but it's what we had and we just wanted some good stuff to uh do this do this demonstration with so we're using the dnmg tool there to rough it we got that say it uh set at 18 000 for revolution so a pretty aggressive feed right there but we're only removing about a hundred thousand to pass [Music] foreign [Music] all right this is going to be our final roughing pass and then it's going to switch tools to another that we'll use to make our finished pass on there [Music] all right there's going to be our finish pass thank you [Music] all right that's going to finish up our our finish there now it's going to retract swap over to our Carmex threading tool we got it running 1500 RPM on this it'll make about 16 passes I believe is what I counted half 28 thread is what we're Machining here weird all right there we go so this part this particular one you got a 10 minute and 22 second cycle time on that this can definitely be improved that's with me getting in there and doing some uh tweaking on the feeds and speeds we're also starting with a two inch material and then bringing it down to an inch and a quarter there but we've got a good looking part beautiful threads all done end to end there using our written Industries face driving tool all right let's take this guy out and uh we'll get a little closer look at it so I did index it what looks like I had pretty well evenly spaced so hopefully you guys will be able to see a little bit of this but you can see your witness marks there from the dry pins that looks good doesn't it yeah this has got the right engagement that you want the the proper amount of force applied to the work piece there so you don't have any problems with it spinning or anything like that and the part looks pretty good so then as I mentioned I I got to do some more fine tuning on our feeds and speeds that we can optimize this and and uh and get maybe a little better finish on it and things like that but I wanted to share one of our shafts that we're turning in a really great example of how we can use this uh face driving tool in the lathe here we talked about how on this particular application for me we're looking for a depth on these dry pins to be somewhere in the range of three to five thousands deep there and once you get a feel for it you can visually see that you're going to be deep enough and especially if you come in here and you can catch those grooves with your fingernail but another way that you can check those depths there is using the stair number 643 dial depth gauge this has more of a knife Aid knife edge ground on the bottom there and a conical point with a 40 degree included angle and all you do is you simply set it on the surface and you push this down with your finger to measure the depth there so that's what we're going to do but the first thing that I want to do is take a stone and actually just kind of just lightly rub this to make sure that there's no Burr sticking up there especially on the edge of the face that's going to give us a false reading just deburr it that's all we're looking for and the other thing you have to consider is that this this material was faced off so you do have tool marks in there that's going to vary in depth depending on where you measure this so you usually start off by getting this set to a zero I use my granite surface plate that's the best place to do it and so I'm not in the groove I'm right off to the next right next to the groove and I want to make sure that it's calibrated near zero so if you rock it you can see it goes past zero just a little bit that's because it depends on where I'm touching that face it could be in a Groove from a tool mark that right there it's pretty close to zero so you have I like to rock it because you got to get it sort of like top dead center okay so I'm going to go ahead and move it over so that the point goes into the groove get it down in there all right and then now we're going to rock it and it may be hard to see but it looks like we're measuring right about three and a half thousandths on our depth on that particular groove right there okay so that's telling me that we actually have proper engagement over our dry pins we're at the proper depth there and this should work pretty good foreign foreign [Music] [Music] [Music] well I've turned a few of these shafts in the miltronics and I gotta say I'm very impressed with the uh the face driving technology now I know the face drivers is not brand new technology I know that they've been out for quite some time and written has been manufacturing these for a while too but it is a new to me technology that I've never seen up close and personal until today in our shop and seeing how this is used is is awesome and I can really see the benefits in high volume high-end production you know if you've got part you've got a lot of these types of shafts that you got to make using a face driver tool is really going to help speed up the operation and not only that using that when you drive between centers like that you're ensuring that your parts have absolute concentricity throughout the entire shaft there you know most times we have to remove it from the Chuck or however you're holding it flip it around set it back up in there and then you finish out the size and you always risk losing a little bit of that concentricity whenever you do that so using a face driving tool where you can machine it from one face all the way to the other one out in one operation is going to ensure that you have absolute concentricity all the way throughout that so really great technology and it's this has been great being able to uh to see this and learn it and hopefully we will be able to apply this some of our work in the future there as well so I want to give a thanks to the fellows there at written Industries for coming out to the shop and helping me with this to not only ensure that I had it installed properly in the lathe there but also to educate me on how to use the tools properly they have a wide range of sizes for their face drivers including the centers there for all different applications so we know that mine is a manual operated tail stock and that's why we're using the spring-loaded center and the spring Lotus Center has those rings on there so that you can gauge the proper amount of force that you're applying to your work piece and that amount of pressure is going to vary depending on the material that you're using the diameter that you're turning and also the link there as well there are parameters that you have to fall within to be able to use a face driver efficiently there but written makes other types of centers there that's used for the face drivers as well so you may have a machine that's Servo driven you know the tail stock may be Servo driven or even hydraulic driven and they can come out to your facility they will whenever you purchase their face driving tools they will come out to your shop and ensure that the machine is being set up set up properly so that you don't have damage to either the center the tail stock or worse yet the the spindle on the machine there as well you can over pressure it which is going to cause issues with bearings if you apply too much force to it so that's where they have their hydraulic pressure or Force tool should I say where they can come out and ensure that the machine is actually applying the correct amount of force needed for that specific operation all right so really enjoyed being able to visit hang out with them I have been using written life centers for well over 20 years now and I've always thought that it was a really high quality Superior product and you know keep in mind that they don't just sell live and dead centers there and they have the they have the scroll Chucks for Life centers as well but if they if there's a tool that you don't see in their catalog they will actually work with you directly to help design engineer and build a specific Center that you need or a specific tool you need for your application so they will work with you personally to give you that tool that you're looking for that you may not find in the catalog but they have a lot of tools to offer there so just about something for everybody out there the other thing that I wasn't aware that they did is they they actually do a repair business for a lot of their customers so think uh shipyards a steel industry um you know Marine industry firearm industry but what they were telling me as an example is uh you know they have a customer that's got these big gigantic lathes you know wartime machines that have huge tail stocks on them because they're turning prop shafts for aircraft carriers and ships you know but here one recently he showed me a couple pictures of a spindle or a quill out of a tail stock that was 24 inches in diameter and it had some damage on it and it had some damage to the taper there as well so that's a service that they provide they actually will take those quills or those spindles to their facility and they will rebuild them for their customers so another great you know service that written Industries provides that I wasn't even aware of I also want to give a thanks to Chris over at Coastal manufacturing solutions for coming out and hanging out with us for the day Chris provided you know he brought this this premet turning tool and the carbide inserts there that we could use as a sample and uh and they did a great job so thank you Chris for that keep in mind that written Industries they sell through Distributors they don't sell direct to customers so in the Southeast they they use Coastal manufacturing Solutions Chris over there so if you're interested in uh written products you can contact Chris over there and he can hook you up he can come out and help you out and he he provides lots of other services there as well so if you have other applications for your machine shop or your manufacturing he's got a lot of tools that he reps and he can he can hook you up that as well so thank you Chris for coming and hanging out it was a pleasure meeting you and thank you for the uh the Turning tool there as well it worked awesome so I think that's going to be it I really had a great time with the guys at written and also Chris we really enjoyed just being able to hang out at the machine here and you know get this set up get it turned in and talk shop you know the the other thing that you can keep in mind I know I'm going to have guys asked about this is that can you use this in a manual lay there as well and the answer is yes so the flange Mount face driver that we have on the miltronics we can take that out and go over to our manual lathe and Chuck that in a four jaw Chuck and get it indicated and use it just like you do here in the in the CNC machine as well or you can take a scroll Chuck and put soft Jaws on it and you know bore the soft jaw so that it so that it holds the the flange Mount there as well so yes if you invest in that tool you can use it in both your CNC and your manual lays there as well so keep that in mind all right so I think that's it we're going to wrap this up and big thanks to written for coming out and making sure that I was using the new tools correctly and hopefully you enjoyed the video maybe you got something out of that and we will see you again very soon
