Warm welcome to today's webinar. Presenters today is me, Niklas Ahlgren, working as Global Product Application Specialist. Yes, and my name is Mikael Karlsson. I'm also working as a Global Product Application Specialist. And my name is Ivar Siksdett. I work here in the center. Great. So, we look into the agenda for today. We start off with the introduction of the new drilling concept. Then we look into applications where we show plug and play function. And then a first demonstration. After that, optimization and advanced drilling operations. And then a second demonstration. After that, we summarize it and ending the webinar. So, let us introduce you to this CoroDrill DE10. The new best-in-class exchangeable tip drill that masters productive drilling in all materials. A universal M5 geometry which offers both plug and play function with unbeatable performance across a wide range of cutting data. It can be applied in a lot of different applications across a lot of industries. For example, heat exchanger plates, which of course consists of a lot of holes. If circumstances are good, I mean tool setup, component, machine condition, etc. We can achieve hole tolerances around H9, H10. Drilling applications, we will go deeper into that later on in the presentation. And to the right, we can see that we cover all materials according to ISO standard. So, CoroDrill DE10, the solution for productivity and sustainability. No pilot drilling is needed. We maintain hole quality through and out the tool's lifespan. We get a long tool life, a plug and play function, and a robust concept that provides a safe and more secure process. A universal M5 geometry. We have angled contact surfaces for the tip in the drill body. And very easy to apply in a mixed production. Thank you, Niklas. I will now take you through a little bit more technical details. I will start with the assortment. So, we are talking drill bodies starting from diameter 9 up to 17.9. Covering drill depth 3, 5 and 8 times D in depth. The drill tips starting from diameter 9 up to 17.9. In increments of 0.1 of a millimeter in drill tip diameter. Also, of course, worth mentioning is that we have a full inch assortment both for drill tips and drill bodies. We can also offer tailor-made, meaning drill body length between 2 to 8 times D if you need to optimize your drilling operation. We can also offer tailor-made on drill tips and there we can offer increments of 0.01 of a millimeter in diameter. And then we can offer the different grades for the drill tips. We are talking about a concept. We describe it as familiar design with newfound security. So, introducing the next level of pretension interface. And advantage, fast and easy drill tip changes. That we have a good strength and high clamping force between the drill body and the drill tip. And we offer the trouble-free drilling at high feeds and speeds. And good centering capabilities that leads to straighter holes and tighter tolerances. And that is the enabler also to be able to drill without pilot up to 8 times D. Also, in the end, having a good interface between drill body and drill tip. Secure that we have many drill tip changes per drill body. So, looking a little bit more in detail on the pretension interface. We are talking about inclined contact surfaces. And we have two different angles on the interface. Working together so we get the tighter clamping when drilling. These two angles work together so they center the drill tip. Because it's a system. So, by having the angles and putting the torque on the concept. We clamp the towers. So, we had a really good, strong centering force on the concept. We can also notice that we have large contact surface between drill tip and drill body. So, the picture in the center, the surface is marked red. That's where we are in contact between drill tip and drill body. Then, to the right, we have the axial lock feature. And that is necessary while having pull-out effect on through holes. Coming into the drill body and to describe the features there. To begin with, we have the through hardened material. It's approximately 45 Rockwell C. We have twisted coolant channels. So, they are twisted in the drill body before machining the flutes. We also have variable helix on the chip flute. And variable helix means quick helix in the front. Approximately 30 degrees. And the slower helix closer to the shank. Approximately 10 degrees. By having this variable helix, we optimize the bending stiffness. But also the dynamics and the torsional stability in the drill concept. Then, we have the margin. The margin supports the drill body and the drill application when drilling advanced applications. And then, we have the laser marking on the shank. Includes article code, but also a data matrix. And using the data matrix together with the Coroplus I find takes you to all product data needed. Including cutting data recommendations. Drill tip geometry. Well, we have the M5 geometry with the optimized shisel. The shisel is the key feature to start drilling a hole. Then, we have the gash. And the gash is optimized to get a good clearance in the center. So, both shisel and gash working very good together to give this good performance in self-centering. Then, we have the land margin as part of geometry under drill. The land margin is designed so you get less smearing in sticky materials. So, taking for instance low carbon steel, stainless steel or heat resistant super alloy steel. Quite often you can get smearing on the land margins. But on our M5 geometry, we have done optimization, you could say, on the land margin. Then, to the right, we have the point angle. The point angle is pretty sharp. It's 158 degrees. And in the center, it's even a little bit sharper. Again, to have a better engagement and start of the hole. We have also added a reinforced corner on the geometry. A reinforced corner, that's also what gives us a better wear pattern in many materials. Because very often you damage the corner on the normal geometry, what you are used to see. But by adding this reinforced corner, this flat surface, we make the corner stronger. And by that also getting much better wear. Coming into the grade and geometry recommendations. We have the one M5 geometry, as earlier mentioned. But we have two grades. One grade, 43-34, to be the first choice if you have the majority of ISO-P workpiece materials in your workshop. 23 -34 will be the first choice recommendation if you have the majority of ISO-MNS materials. By having these two grades, you have the opportunity to choose, depending on your mix of materials, your first choice grade that you have. Also to take into consideration is that you have a little bit more wear resistance on the 43-34. And a little bit more toughness on the 23-34. And then we have the geometry where we don't compromise on performance and cutting data. We are talking about the M5 geometry, where we have recommended cutting data on a certain level. I would say productive and relevant level. But we also know by experience that there are sometimes limitations in machines. So, for instance, if you have a lathe machine where you have a limitation in RPMs, it could be useful also to reduce cutting data. It can also depend on stability, on fixtures, etc. But then, of course, in the end, we do know that productivity is what contributes the most in production, especially to reduce cost per hole. So, also within the cutting data window, we can increase the cutting parameters quite a lot. And we will go through that later on. So now, Niklas, time for some demo. Yeah, yeah. Yeah, yeah. Yes, so now we will go into the first demonstration. And in this demonstration, we will show how easy it is to apply this drill. So, plug and play function. We will drill through or drill in five different materials. And it is titanium, 6-4. If you look up to the right, we see that we have five different workpiece materials. So, titanium, then we have stainless steel, 316L. And in the middle, we have alloy steel, 2541. And to the right, we have 1672, so low alloy steel. And to the right, aluminum, 7075. We will drill three different cutting data for each material. We will use the same drill body and tip and grade, obviously. We will drill two holes per cutting data. So, we're starting off with titanium. In this case, titanium 6-4. So, we will drill with lowest cutting data. 30 meters per minute, 0.1 in feed rate. And then we go into the recommended cutting data. In the middle of the cutting data window, 40 meters per minute, 0.15 in feed rate. And then, maximum cutting data, 50 meters and 0.2 in feed rate. We will try to be quiet during this demonstration. So, you can hear the drill. And it will take some time due to titanium, in this case. To be said, this is eight times D drill, 100% on feed rate. On entry. Second hole, same cutting data. Third hole, same cutting data, 30 meters per minute, 0.1 in feed rate. Then we step up to 40 meters per minute, 0.15 in feed rate. We can see that we have good ship evacuation and no problem at all Even though we use the lower cutting data and going on in different Cutting data windows now it's the highest cutting data 50 meters per minute 0.2 revolution And then we go into the stainless steel so 316L in this case Still same drill a times D diameter 13 The lowest cutting data minimum in the window is 40 meters per minute 0.11 in feed rate per revolution And then the recommended cutting data 60 0.16 and then maximum 80 and 0.21 So Start with the lowest cutting data 40 point 11 Then we step up to 60 meters per minute and 0.16 in feed rate And then the highest cutting data 80 meters per minute 0.21 in feed rate And then we go into the alloy steel which is with a hardness of 300 Bernal Same drill and tip so the lowest cutting data in this case will be 80 meters per minute Then 0.18 in feed rate and the middle of the cutting data window 105 meters per minute 0.34 in feed rate and then maximum 140 meters per minute 0.45 and to repeat we use 100% feed rate on the entry now when we have a flat surface even though we use eight times the drill in this case So lowest cutting data first So lowest cutting data first Then 105 0.34 Then 104 0.45 And for the low alloy steel we use same cutting data so this has a hardness of 180 Bernal So we go on with that directly We can hear that we have different sound Drilling this material compared to the slightly more difficult Yeah or Little bit Little bit softer material so lower cutting forces and lower torsional sound Yeah So the last one out is the aluminum 7075 So the lowest cutting data in this case 160 meters per minute 0.26 in feed rate And then the recommendation is 210 meter per minute 0.36 And then maximum 250 0.42 Yeah and maybe worth mentioning here that using the high cutting data in aluminum also needs good coolant flow out from the drill tip and especially if you are drilling full depth hole In our case we are drilling 2 times D, 3 times D approximately But in your applications if you have deep holes keep that in mind that to utilize the high cutting data you also need good coolant flow Good So we run these That was it All materials one drill So we look into the chips now And we look on the chips from the recommended cutting data for each material So first out low alloy steel Then alloy steel And then the stainless steel Titanium And aluminum And something to add there Well we can add that in this case on the recommended cutting data for the different work piece materials We see a good chip control And that is of course very positive that even with the one M5 geometry and all these different types of materials We have good chip control And that is of course you know easy to evacuate in the end Yeah Good We did also measure the holes after this This was just to see how the different materials and cutting data would affect the diameter of the finished hole So if you look here we can see that only this hole actually have slightly It's on the maximum when it comes to a H9 tolerance Otherwise the other one is within the tolerance We did measure with a three point caliber or micrometer in this case Yeah And reflecting on the measurements a little bit I mean we are talking microns here And one of them are slightly above H9 But going forward in the presentation I will explain why that happened So I think it's a really good result Yeah Yeah So I leave over to you Yes, thank you Niklas Yeah, I will take you through the The applications and going forward a little bit more into the different advanced drilling operations As we say As mentioned earlier We are offering Hole making in different types of components So whether there are holes we are interested to drill them with CoroDrill DE10 The most common drill is for sure the solid hole with a flat entry And in some cases or also in a couple of cases the through hole with a flat exit But it can be worth highlighting that also sometimes the entry and exits are angled It can be forging And that's a little bit more demanding You need a certain strategy to succeed with those applications And as mentioned earlier We have this M5, the plug and play And we can cover all work piece materials So how to apply them? Well, to begin with We have the window to the bottom right Where we have a recommended cutting data And a minimum and a maximum Using 3, 5 or 8 times D drill lengths We don't make any difference when applying the different cutting data So no difference in cutting data for the different lengths of drill One thing that is a little bit sensitive is when using 8 times D If you run too low feed Because on that note Running too low feed Can actually give slightly larger entry diameter And coming back to the demonstration that we just saw We could see an oversized toll in titanium Due to the feed was maybe a little bit too low in that case Also worth mentioning once again That you don't need any pilot drill for the 3 to 8 times D drills Regarding whole quality and cutting data Well, whole quality H9, H10 We can achieve those And in most cases And in most cases you reach H9 No doubt There might be situations where also H10 is achieved And I would say that's influenced by tool assembly Shorter or longer assembly will affect whole size a little bit Stability And of course Sometimes also a machine can influence the achieved whole size But in general very good toleranced holes And repeating the message then Don't apply too low feed Because then you can get oversized holes So what's the strategy to be used in advanced operations? Well, we have one simple strategy General strategy And that is to reduce the feed When you have angled entry Up to 10 degrees Angled exit up to 30 degrees Or you have a convex surface Or a concave surface So the strategy is pretty straightforward We reduce the feed down to one third of the recommended feed rate For the specific application And you apply that reduction of course When having these sections of the hole So you need to use G1 in your ISO programming Different feeds for different passages of the hole Also worth mentioning I mean this is a general recommendation But it can also be influenced by Drill length, stability and work piece materials So keep this or see this as a recommendation to start with Then you might need to optimize even further But for sure the concept can do it And that is what we want to promote in this webinar That we have a really good pre-tension interface That can do this type of operation So now we are coming closer to the demonstration And we have prepared a component Where we have concave Radiuses in the entry We use the strategy to reduce the feed We then have convex radiuses We use the same strategy there Then we have a cross hole And again following the general recommendations And again reducing the feed Then we have just a through hole I wouldn't consider this as advanced But it's part of the demo So we are running the full speed And feed throughout the hole And then we are really challenging passage of the demonstration We have entering angle of 10 degrees But then we also have exit angle of 30 degrees And using the same strategy as already described earlier Reducing down to one third of the recommended feed Down to 0.09 So now it's time for some demo Demo Andreant Great. So, during the introduction of this drill concept, we captured that we get a great benefit of increasing the feed rate up to 40%. And by increasing the feed, we also increase productivity. If we increase productivity, we can reduce the CO2 emissions. We have also seen that we get approximately 40% longer tool life than compared to all the reference drill during the development of this concept. So, it's time for a change. What are you looking for? Is it higher productivity? Minimizing energy consumption? Or is it longer tool life? Maybe all of them. So, thank you all for attending this webinar and listening. Yeah. Yeah. Yeah. Thank you all and good luck with drilling of Core Drill D10. Thank you. Thank you. Thank you.
