Grinding Bone Pins on the Walter Helitronic Vision 400L | United Grinding

[Music] hey what's up everybody this is scott with titans to cnc and i got more for you on the walter helitronic vision 400l from united grinding today i'm going to show you how to manufacture on an automated process of the bone pin [Music] pretty solid hopefully you've never had to experience one of these but if you've broken a major bone in your body that bone has to be in place for an extended period of time this pin is actually driven into a good portion of your bone and fixed to an external fixture that's going to hold your bone in place until you heal maybe you've experienced that before and you can tell us about it in the comments below but we got to make these and we got an automated process with our lr mate fanuc robot behind us so i'm going to show you guys how to get that all set up show you guys some of our wheels and show you the process and how we can get this part manufactured [Music] so as we're setting up our robot we have our three quarter inch pilots here which we're not using for this particular job but we have our quarter inch pilot since we're using a quarter inch surgical steel and we're going to load these all up so that the robot can put them in the machine for machining and they'll bring them back to this pallet once the process is done we need to do this in two operations we're going to do the driver which is really similar to your your typical drill bit and then uh our op 2 is going to be our screw so it's got a cutting edge on the on the tip and it's also got flutes all the way down for your thread let's uh go ahead and run a couple parts [Music] do we have various wheels and these are going to be cbn wheels our cubic boron nitride the cbn is a little bit better for materials such as this surgical steel and other stainless steels with these are various shapes and sizes as you can see this one's pretty simple just round this one's got like a cup shape to it also has a wheel on the back depending on how many wheels we need or the geometries that we're trying to get on this tool will depend on how you're going to pack your wheel so so now i got a couple different variations of coolant i've got my flex hose and my my hard pipe depending on the application you're trying to achieve maybe these flex hoses are going to work well for you or maybe you need to bend some copper pipes they're going to be a little bit more rigid and you can control the flow coming out of the tip if you squeeze this if i got my 1a1 wheel here i can load this up and then i can load up my manifold and now i can set up my coolant in our machine we have the blazo grind hc10 grinding oil [Applause] something really important with grinding wheels is dressing just because i get a wheel brand new from the manufacturer doesn't guarantee that when i load it up on this wheel pack that it's going to be round so it's important to dress it to true it so what we have here is a dressing wheel this is aluminum oxide this aluminum oxide wheel is going to be used to dress this cbn wheel into shape on our walter it actually has programming inside of it so we can dress our wheels in the case we need to and in our case we did if you were using sandpaper on something it loads up with material it's not as good as it was when it was brand new the same things happen with grinding wheels when you're grinding steels and carbides sometimes they load up with material and you need a way to refresh the wheel or clean out some of that grit and what we say reopen the wheel and we're going to do that with this aluminum oxide stick it's called sticking the wheel so we're going to turn the wheel on we're simply going to take the stick and stick the wheel all right so i wanted to talk a little bit about the nomenclature of the tip of this now right off the bat you see the thread right that the tip it's not just a tip it's made up of a couple different operations and i wanted to bring those up to you guys so we've got the gashing we have a clearance a secondary clearance and then a tertiary clearance now the gashing is what's responsible for creating your chip formation and which is really important for this particular tool because you know you're drilling in a bone now there's going to be a pilot but there's obviously some cutting edges on here so that we are you know making a clean cut because it's going into your bone you don't want it fracturing or anything or causing any more damage you just want this drilled in nice and snug so it can hold that frame onto your leg what you would typically see or what you might perceive as your cutting edge which is the edge right above the gashing it's really flat that's what's actually going to be cutting into your material that's known as our primary clearance and right behind that would be our secondary clearance now it's important that you have a steep angle on that secondary clearance because as the tool is coming around you don't want material sticking out too far it's actually going to cut or rub on top of your cutting edge or your primary clearance so now that i got my screw i got to make sure it works there you go johnny legs fixed it works hey guys so i hope you really enjoyed that whole process with the robot op1 and op2 hope you learned something about some of the different terminologies of various tools now on the next video i'm going to show you guys how to program this guy now the walter software tool studio is really easy to use it's a lot of fun so i hope you stick around for that if you guys like what you saw today go ahead and like and subscribe send your comments down below i love interacting with you guys it's a lot of fun i hope you guys enjoyed this stay safe so that you don't need a bone screw in your future we'll see you guys next time
