Hello and welcome to this webinar that we are sending from Samvik Coromant in Samviken,Sweden. Today we will talk about Corrodrill DE10. And as always, for us at Samvik Coromant, safety is always highest priority. I hope you know your emergency drill in case of emergency. We know what we need to do. We don't have any planned alarms what we know. So if something happens, we need to leave. Presenters today is me, Niklas Halgeren, working as application specialist here in Sweden. And my name is Mikael Karlsson. I'm working as a global product specialist for indexable drilling. And my name is Lukas Larsson and I work here as a showroom technician. Great. So I will walk through the agenda for today's webinar. First, we start with an introduction of the new drilling concept. And then we go into applications and plug and play. Then we start with some demonstrations, some machining. And then into optimization and more advanced drilling operations and applications. And then we have a live demonstration in the machine beside here. And then summary and questions and answers. So we ask you to type in questions to us and we try to answer them in the end of the webinar. Yeah. And you can use the Q&A function and it's anonymous if you want. Great. So let us introduce you to our new drilling concept called a drill DE10. The best in class exchangeable tip drill, which provides productive drilling in all materials. We have universal M5 geometry, which provides a plug and play function and also a really good productivity in a wide range of cutting data. So into more application to the left, we can see examples of components. So for example, heat exchange the plates, which of course is a lot of holes. We also achieve H9, H10 hole tolerance in, of course, if we have the circumstances and the setup and everything in the machine for the tool. It can also be used in a variety of drilling applications, which we can see in the middle of the slide. All these applications that have different demandings. We will go deeper into this later on in the presentation. To the right, we can see that this drill will handle all the different ISO grouping of the materials. So called drill DE10, a productive and sustainable drill. We don't need any pilot drill for this. And we maintain whole quality through and out the tooltips tool life. We get a long tool life. It is a plug and play solution. And we also have the robustness, which give us a safer and secure process. We have a versatile geometry M5. We have inclined contact surfaces. And we also say that this is, and it really is, easy to apply in a mixed production. So over to Michael. Yes. Thank you, Niklas. I will take you through, to begin with, I will take you through the assortment. So we have an assortment introduced between diameter 9 and up to 17.9. We have increments of the drill tip diameters between 0.1. So in step of 0.1 on the diameters, we are talking three different lengths on the drill bodies, 3, 5 and 8 times D. And we have two different grades that I will describe a little bit more detailed going forward. And important note and information here is that diameter 9 up to 10.9 will be released October 1st this year. So today on stock starting from diameter 11 up to 17.9. So we have a concept that we describe as familiar design with newfound security. With this type of connection, we can do fast and easy drill tip changes. We have a good and strong connection between the drill body and the drill tip. And we aim to have a trouble free drilling. And especially at high cutting data, we know that we have a reliable concept. Thanks to the connection being strong, we also know that we get a good self centering function, thanks to that. And we are talking about the next level of pre tension clamping interface being released to the market. Going through the interface a little bit on the left hand side, you can see some inclined axial contact surfaces. And by having that, maybe it's difficult here to see, but by having the angled surfaces on the contact, we also get a clamping force between the drill body and the drill tip while drilling. So this is one of the new features we have on this pre tension interface compared with similar concepts. By having this reliable connection, we also, thanks to the cylinder in the center marked red, on the body and on the drill tip have a really good self centering capacity. And also you can see the red surfaces also taking the torque and the load from the feed forces on the drilling process. To the right hand side, you also have the axial lock feature that can be useful in some applications when you have a pullout effect. On the drill tip while drilling through holes. The drill body have twisted coolant channels. Also, we have a variable helix on the chip flute. So we have one helix angle in the front, approximately 25 degrees. Then we have a smaller helix angle closer to the shank end in helix angle. And by having this, we also get the more bending stiff and more bending stable drill body. Also can be important to highlight the flute shape that actually is pretty deep. So you have a good space to take care of the chip being produced. The drill body also have a land margin to secure that we get the chips out from the hole. When you have this type of, you could say, needs. Material and hardness in the drill body. It's a fully hardened drill body. Approximately 45 Rockwell C. The exit of the chip flute is also optimized. So it's important when you have the need of drilling full depth holes. that you actually have a very, how should I say, reliable exit of the chip. Laser marking. On the flange, you have the diameter on the drill body. And then on the cylindrical shank, you have both the article code, but you also have a data matrix. And this data matrix you can use together with the Coroplus iFind. And by doing that, you also have the connection to all product data, including cutting data. The drill tip and the M5 geometry, looking on the left hand side on this slide, you have the chisel and the gash working together to give good engagement of the component. And this is really key for a drilling process. If you have a good start of the hole, you will also continue to drill in a good way. And you will exit or you will end in a good way. So the chisel edge and the gash are really important. And they are kind of optimized to do as good as possible. In the center, we have the key grip. And then we have the land margin shown. And the land margin, I also want to describe a little bit. It's actually not only a cylindrical land. It's actually a geometry on the land margin. And by having a geometry on the land margin, we also optimize drilling process. And I would say the wear pattern that you get. Because in some materials that are smearing on the land margin, you will get less of that. If we take, for instance, stainless steel, low carbon steel, that quite often sticks on to the outside diameter of the drill tip. By having this geometry on the land margin, we reduce that. And that also is a key thing when it comes to keeping the tolerance throughout the drill tip to life. On the right hand side, we have the point angle. And you can see in the center that it's a little bit sharper. And again, then this helps to engage the component and have a good start of the hole. Good position. I also, or we also want to highlight the corner of the geometry. We describe it as being reinforced corner. So it's a grinding operation being done on the rake side on the cutting edge. So we reduce the helix angle in the corner of the drill tip geometry. And by doing that, we increase the strength of the corner. And this is especially a good thing when we are drilling through holes in demanding applications and materials. So the corner is also something that is really a good thing and really good optimization on this M5 geometry. Coming into the grade and geometry recommendations. Niklas said in the beginning that this is a versatile and a plug and play concept. And by having the M5 geometry as the one and only geometry for all workpiece materials. How we then recommend depending on workpiece material in your workshop. Is that if you have ISOP as the main portion of your workpiece materials. We recommend the grade 43-34 to be used. If you instead have stainless or nickel based alloys as your majority of material in the workshop. We recommend the first choice to be 23-34. So basically these are the two guiding stars I would say. That you should choose the grade that fits your mix of materials the best. And by having this one geometry M5 you don't need to compromise. So we, to begin with, we don't compromise on the different workpiece materials. Also we don't compromise on the cutting data being possible to apply. So already from start we say that we have a recommendation of cutting data. We have a recommendation of cutting data on a good productive level. So already from start you should have a productive drilling operation. But there can also be reasons behind when you want to optimize and change. It can be that you want to drill even faster and go up in cutting data parameter. It can also sometime be that you need to reduce the cutting data. It could be limitations in RPMs in a lathe machine as an example. It can also be stability issues. And then you might need to reduce sometimes. So this together makes a large cutting data window available with this product. And this is also one thing that we want to show you going forward. So I hand over to Niklas again. Thank you. Exactly. So what we will now try to demonstrate for you is the plug and play function for this drill. So in this case we will machine five different materials. If you look on the top right you can see how it is fixtured. We will machine titanium 6-4 and austenitic stainless steel 316L. And then alloy steel and then low alloy steel and aluminum 7075. So if you look to the left we can see that we have two holes for each cutting data in the cutting data window. So the lowest cutting data, the recommended and the max cutting data. And on the bottom right you can see how we have positioned this in the work pieces. We will drill 32 millimeter deep hole. So looking into the first one out is titanium 6-4. We will use a 30 millimeter DE10 drill. Eight times D in drill length. So a long drill. In this case we start with the lowest cutting data. 30 meters per minute and 0.1 in feed rates. And then 40 meters per minute and 0.15 in feed rates. And also to the right the maximum 50 meters per minute 0.2 in feed rates. So we will start this and this is a pre-recorded machining sequence. And of course grilling requires emulsion coolant. So we will have some coolant on the camera as you can see. So first hole 30 meters per minute 0.1 in feed rates. So we will see that. Yeah, and it can be worth mentioning when drilling titanium. The cutting data window is a little bit more narrow if you compare it with drilling in steel as an example. So what we actually are doing now is we are drilling from 30 up to 50 in cutting speed. And we have the 0.1 in feed that we see now on these two holes up to 0.2. So it's pretty normal I would say for a difficult to machine material like titanium. Yep. So it's now 40 meters per minute and 0.15 in feed rate. And we can see the ships that are generated and also evacuated from the hole. 100% feed rate in the entry. Yes, correct. If it's a flat surface. Yep. Even if it's an 8x D drill. Yep. Highest cutting data now. So 50 meters per minute 0.2 in feed rate. So next one out is Austinitex stainless, so 316L. Same drill and drill tip of course. To the left we can see the lowest cutting data, 40 meters per minute 0.11 in feed rate. We have 60 meters per minute and 0.16 in the middle. And also the maximum cutting data 80 meters per minute and 0.21 millimeter per evolution. So we start at. So 40 meters per minute and 0.11 in this case. We hope you can hear the sound. That's why we also are a bit quiet here. Yep. And what you see also when you start drilling the hole, of course you get the starting ship. So after that, in general, we see short ships being drilled and produced. So now we increase the feed, the cutting data to 60 meters per minute and 0.16 in feed rate. And the last cutting data is 80 meters per minute and 0.21 in feed per evolution. So next material to machine is 0.21 in the next material. So 2541, we usually say. 300 Brunel in hardness. And the lowest cutting data in this case is 80 meters per minute and 0.18 in feed rates. And then the recommended cutting data 105 meters per minute and 0.34. And then the maximum cutting data 140 and 0.45 in feed rates. So this will be quite faster. 80 meters, 0.18. And then 105 and 0.34. And the last one, which was drilled right now was 140 meters per minute and 0.45 in feed rate with an 8xD drill. Yeah. And then we have the low alloy steel. We use the same cutting data. This is slightly softer material as well. 180 Brunel. So we go on with that. So first, lowest cutting data. And I think that you can hear a difference in sound. It's a little bit softer steel, so it's a little bit less sound when drilling these holes. You can hear the chips. Yeah. And then we have aluminum 7075. So to the left, 160 meters per minute and 0.26. That's the lowest cutting data. Then the recommended cutting data 210 and 0.36 in feed rates. And then maximum 250 meters per minute and 0.42 in feed rates. Yeah. Something to add. Yeah. I just want to highlight the importance here that when running these high cutting parameters, it's also important that we have coolant flow secured, especially if we are drilling deep holes. Because there will be a very high feed rate in the machine. So you need also to secure that you evacuate the chips. Just to highlight that. Good input. So we start off with 160.26. 160.26. 210.36. 250.42 in feed rates. So we will look at the chips now from these different materials and we will look at the chips from the recommended cutting data. With that said, the cutting data in the middle of the window. So first out is the low alloy steel chips. And then the alloy steel. We have the austenitic steel, stainless steel. And then titanium 6.4. And to the right we have aluminum. Yeah. And I mean, small comment from my side here is that you can see that the chips are in general short. And that's very positive. You can also see that the alloy steel, the little bit harder one, the second from the left, it's a little bit shorter than the one to the left. You can also see that actually titanium is really short in this case. And again, very positive. I also want to mention that we are aware that sometimes we don't get these short chips in all workpiece materials. That is not a big concern from our side because we have experienced that we evacuate the chip in a positive way anyway. But for this demo, actually, it turned out to be very positive short chips. Yep. Yep. And then we also measured the holes for all these different cutting data to see how it affected the drill when it was such a long drill. And we can see that all the measurements will fit within the H9 tolerance, except this one, which is some thousands above. But then we are measuring with a three point micrometer as well. So that's slightly too precise for that measurement. And we will also explain going forward in the presentation, maybe the root cause for this a little bit larger hole. Yes. Maybe we have a solution on that. With that said, leave over to you. Yes. Thank you, Niklas. Thank you. Yeah. Repeating a little bit. We have released this Coral Drill DE10. We are targeting components with holes in. And we do know there are components out there with holes inside. So we're interested to drill these. And H9, H10 tolerance, that's the target. We're interested in that if we have everything else in place, like run out, stability, and in some cases also applied cutting data. We do know that we can drill solid holes and also some advanced applications that I will show you later. And then work piece materials, we can drill all of them. Applying three to eight times D drills, we don't do any difference in cutting data recommendations. So we apply the same cutting data recommendations, even if it's a three, five or eight times D drill length. And that's really important to be aware of because we see an influence in hole size when applying to low cutting data. So I want to highlight in the bottom here that if you are running too low feed per rev, the result can be that you get a little bit larger hole in the beginning. And that can be the reason for the oversize in titanium that we actually saw on point one in feed. Another thing, of course, as we have mentioned earlier, we don't need any pilot drill. So that's also something positive with this concept. And keep in mind the opportunities. Start with the recommendation and then depending on your needs, apply the cutting data within the cutting data window. And the hole quality. Well, H9, H10, we're talking hundreds of a millimeter in achieved hole tolerance. We also want to share that we keep that tolerance within the full tool life of the drill tip. And how can we do that? Well, we have a corner geometry that actually allows this. So the maximum diameter of the drill tip is below the corner of the geometry. So the hole is generated slightly below the cutting edge. That means that even if you have a flank wear on the drill tip, the cutting edge, it will not affect the hole size. And that's important to be aware of. So thanks to that, we can actually keep the tolerance, the full tool life. And then again, keeping the tolerance by applying the right cutting data. Coming closer to how to apply the drill in advanced applications. We have angled entries, exits. We have convex and concave surfaces. And these are, I mean, relevant at your application on your components. And we have tried to create some guidelines how to apply cutting data for these. So up to 10 degrees. Entry angled. And up to 30 degrees. Angle, sir, exit. And then we have a relation on the convex, on the radiuses for convex and concave. And then the cross hole. So what we say is, we should reduce the program feed to be one third of the recommended feed rate. And we will take it through now, a live demonstration where we apply this strategy. So we have here concave radius. Where we use the strategy being presented. So we reduce the feed down to one third of the recommendation. Next slide. Next slide. It's convex radiuses. And Lucas, who made this demonstration. He has challenged the drill quite a lot. So we are talking pretty small radiuses here down to 7.5. It's actually outside our recommendation, but we will show it and it works. Then we have the cross hole. Applying the same strategy. Then we have a through hole. And finally, we have the angled entry and angled exits. And worth mentioning then, we are really on the limits here. So we have the maximum entering angle of 10 degrees. And we have the maximum exit angle of 30 degrees. And this is a real challenge, but it works. So Lucas, time for some live demo. And now it is the cross hole. As always, when doing drilling demonstrations. Difficult to see. Due to the coolant flow. Now we have the angled entry of 10 degrees. And now we have the angled exit of 30 degrees. And an exit of 30 degrees. Thank you Lucas. As many times before, we have succeeded with the live demo. We trust the concept and we can do these difficult operations. So, Niklas, time to summarize. Yes, so during the introduction and testing of these products. We see that we get great benefit of increasing the feed rate by 40%. And by increasing the feed rate by 40%, we also increase the productivity. And by increasing the productivity, we can lowering the emissions. Due to shorter operation times, lower energy consumption. And we also have seen that we get approximately 40% longer tool life. Compared to all reference drills that we have done during all testing. So, it's now time for a change. What are you looking for? Is it higher productivity? Or longer tool life? Or maybe some combination of this? Reducing energy consumption? As really, reminding teachers, as really as many modern custom resources. Ad вжеe is a very poultry team part in myхtalley is not worth it. Lucas to see if there are any questions. Yes, we will. We will have drills up to 12 times D released in the next coming year. So 10 and 12 will come. Was it all? Yeah. Okay. So it's time for us then to say thank you very much for listening in. It's been a pleasure to have this presentation and keep in mind now, it's time for change to Coral Drill DE10. Thank you all. Bye-bye.
