We have Justin Lennaro, milling product specialist from South Europe. Julia Corana, showroom technician from Coromans Center, Sandvik in Sweden. He will show demo parts. And we have Stefano Bertoni, milling product specialist from South Europe. I will now hand over to Stefano to share. Stefano, stage is yours. You can start your presentations. Thank you, Pinar. Welcome also for my side. The topic for today is the Coromill MF80. MF acronym is Milling Face Milling Cutter. It is a face milling cutter and shoulder milling cutter. Now we talk about the fixture for this cutter. The MF80 is a cutter for phase milling and roughing operation close 90 degree. The two materials that is possible to machine is ISO-P and ISO-K. I mean cast iron and steel. It is possible to apply in general engineering operation for roughing, semi-roughing and also finishing operation. But it is possible also to apply in other most important segment, industrial segment like automotive, power generation, pump and valves and oil and gas also components. The important point for this cutter is a multi-hedge cutter. It is a double-sided concept. We have four plus four cutting edges. We have a very good cost efficient cost. Our hedge is a close 90 degree. Remember, it is not real 90 degree and is good to use this cutter for when we have picturing constraints, for example. Or when we work with machine components with limited setup, limited stability. For example, when we work with thin floor components like structure, for example. Some feature. The entry angle is 89.5. Remember, it is not real 90 degree. We have a very cheap room, big cheap room evacuation. We have internal coolant for better cheap evacuation, but also to control the temperature during the machining process. We have a very big robust tip seat to where we have a very big axial radial support to have a better stability with the with the insert. And also we have the shim to protect the insert and the cutter body. In this case, we have a highest security. The other point is we have a new tools profile. I mean, we reduce the weight of the tool body 35% for two reasons. One because we reduce the material around the body and we have the possibility to work close to the fixturing of or strange shape of components. The other hand, we have the less frequency during machining. We have less weight during rotation and it means we have less vibration or absent or without vibration when we work for example with long overhang applications. If we talk about the insert insert, we have eight cutting edges, four plus four cutting edges. The maximum AP available is nine millimeter depth of cut. We have in the opposite side for the first cutting edge, we had a cheap protector on the unused cutting edge. We have a small BS 1.6 millimeter. The BS is the parallel end that produce a surface quality in the in the component. We have a very good optimized corner radius for this introduction. We have radius 08 but is optimized to work in both material. ISO K and ISO P in a good way. We have also in the first cutting edge. We have the optimized micro geometry. We have a very positive cutting geometry that is possible to work with cast iron to don't break the the piece. And in the same time to have a good cutting edge when we machine steel to avoid the bracket. Remember the cutter is double side cutter, double negative side cutter. We have a very good cutting edge. We have a very good cutting edge. We have a very light cutting action and low cutting forces during machining. Some applications. It's possible to apply in engine blocks, for example, gearbox housing. In sterling knuckle is possible to apply housing, but also other components like body valves, frame, axles, carrier, carrier, covers, support and etc. We have a lot of opportunity to apply. Jocelyn, help me please to show the positioning for the new cutter, please. Thank you. Welcome to all. Cormule MF80 positioning. So when we talk about all the milling operations, we have in mind face milling, shoulder milling, repeated shoulder milling, full slot milling and ramping operations. And all the all kind of material, ISO-S, ISO-M, ISO-K, ISO-P, that means super alloys, stainless steel or cast iron and steels. As a wide and versatile application field, we will recommend to apply coromile 390 in size 17 or 18 for the highest material removal rate, as that means equal to the productivity. And as it is with a perfect 90 degree entering angle, it is optimized also for repeated shoulder. With the specific design of the insert, it is possible also to apply it for ramping operation or helicoidal interpolations. Also in the wide range of materials, coromile 490 with four cutting edges on a square insert can be applied. One limitation will be due to the specific design. It is not absolutely not recommended for ramping operation, but the be sure that for all the main core milling operation, it is an optimized solution, giving a relatively high material removal rate. By then, all the previous concepts presented right now are with a true 90 degree entering angle. Now, when we talk about close to 90 degree, and that is the case for MF80, as Stefano mentioned, it is 89.5 entering angle. So not exact 90 degree. And especially dedicated for cast iron applications and ISO-P steel applications, thanks to the double sided insert, square insert that provide eight edges per insert, it is a cost-efficient milling solution for face milling and shoulder milling when we accept a close 90 degree on the wall. Today in the introduction, we introduce on the bodies starting from diameter 63 with M, that is medium course pitch with a different differential pitch. That means the space between each teeth are not equal and that breaks the tend to have vibrations with long overhang or unstable applications. In each pitch, that means fine pitch with higher density, the bodies will be on even pitch, that is the space between all the the two teeth are equal, starting from diameter 80. Up to both bodies programs, up to diameter 125. Concerning the insert shape, it will be a single geometry M-M50 with the radius, the point radius 0.8, the point of the height, and associated with the dedicated grades for steel 11.30 and 43.40. For cast iron, we will recommend first 10.20 or 33.30. Let me remind you that 43.30 can be an alternative in some cast iron applications. Usually, the usual ship thickness recommended is around 0.18 and can be reached up to 0.3 in cast iron, open 25 in steel and be sure that the concept is very strong and in some cases we can reach slightly over than this recommendation. Now we see some process consideration. As I said before, the MF80 is applied for face milling and shoulder milling. What is the difference? The difference is the radial engagement. We have a different AE. In phase milling we have a very large AE, big AE. I mean we have 70, 80, 100% full engagement with the cutter. When we work in shoulder milling, we have a small AE and the AE is very, very thin. Also, the arc and cut is different. Now in the next slide, we try to go deeper. What are the differences? So we have a big radial engagement with the surface. When we have a big radial engagement, we have a big arc and cut, long arc. I mean when we have 70, 80% DC. We have in the same time high heat transferred into inserts. We have rubbing. In this case, we recommended to use CVD grades, for example, because we have more coatings and we have the best protection. In the other hand, when we have small AE, it is like a contouring, side milling. We have 20, 15, maximum 30% DC in contact. We have a short arc. In this case, we have a short limited contact heat transfer. It means that in this case it is possible to put more higher VC compared to the phase milling operation. For example, in this case we recommended to use PVD grades over. For example, we have only one coating, is a very sharper edge. We reduce cutting forces. We reduce the temperature and we have a very smooth and light cut. We reduce the temperature and the short arc. And in the other hand, when we have or we use short arc, small AE, we have a different feed. I mean, we have to modify the feed. Just Leng, please explain. Yes, as you said, chip thickness is in link with the feed, the feed per tooth. And feed per tooth is given in the trajectory of the axis of the cutter as it is represented here in a face milling operation where chip thickness equals the feed in this trajectory. By then having a side milling, a shoulder milling, as this feed per tooth is given in the trajectory of the axis of the cutter, the real chip thickness into the material is reduced as the arc entering in the material is far away from the cutter axis trajectory. That means HAX, the chip thickness, is smaller than the feed per tooth applied. By then, in such circumstances, it is possible and it is recommended for sure to increase the feed per tooth to raise the chip thickness up to the normal recommendation. And in this case, for the same chip thickness comparing face milling and side milling, in this case, feed per tooth will be increased in this example by about 40%. So for sure, chip thickness is the recommendation we will find in our cutting data recommendations and it has to be applied accordingly your applications. With MF80, that means that in a face milling operation, when in cast iron, the width of cut is around 80% of the diameter, we will apply up to 6 mm depth of cut and in ISO-P we will recommend not to exceed 70% of the diameter. As Stefano precise it in the insert features, the geometry the insert geometry can be applied up to 6 mm in regular applications. By then, depending on the component, shape, or variation on the casting or forging, the insert can machine up to 9 mm without compromising any cutting edges available on the 8 cutting edges insert concept. That means that means in regular machining you can apply normal cutting data up to 6 mm but in punctually in some parts of the component it will absorb the overstock on this material. Talking about facing operation, we regularly program straight away easy way of programming trajectories. Unfortunately, that is not the best art of milling. The insert, the edge, gets inside the component and gets outside the components so many often that it is, it will provide a limited to life. What we usually recommend in such facing operation is to enter once into the component material and having a continuous contact trajectory for the cutter into the material. That will provide you the best productivity performance and also the highest, the longest tool life. About entering into material, we strongly recommend to have a roll trajectory rolling into a cut into the material. That will provide you the best part of the material. And we will give a stable machining and optimize the insert tool life. If it is not possible to have a roll in to cut into the material, it is also possible to program a radial ramping penetration into the material. With an angle of 20 up to 30 degrees, it can be sometimes more easy to program instead of a roll in. But for sure, program a gradual, gradual penetration into the material as much as possible. It is not a pure 90 degree concept. So that means by using it in repeated shoulder milling, some recommendations have to be respected. Especially when the total depth of cut will exceed these 6 millimeters as we recommended, 9 millimeters in some cases. So with 89.5 degrees entering angle, the diameter on the upper side of the insert will be wider than on the lower level of the insert. In that case, in repeated shoulder milling, we recommend relief of open five every 6 millimeters depth. That is important not to have an early worn out on the upper edge, unused upper edge. Let's see some of these features in demo. Can we join Sweden? Can we join our showroom with Julio? Yes. Hello Julio. Now you can hear me. Yes, that is yours now. OK, thank you and welcome to the center in Zambican in Sweden here. My name is Julio Corona and I work as a technician here in the showroom. And with me I have my colleague. Yes, my name is Lukas Larsson and I also work here as a technician in the showroom. So yeah, we can start right away with the demonstration that we have prepared for you. The first thing that you want to see is, yeah, this work piece, it's a standard steel here in Sweden. We have the. 290 brunelles. And we're going to use the machine. Doosan NHP 5000 with a. With a BT40 big plus spindle. And what you're going to see first is the dynamic phase milling. Where we're going to use the. Dimensional 63 of the cutter. We got, we got the speed, the 230 feed 0.8, the 18 three. And AP five limiters that. And engagement of the cutter will be 40%. So we can. Start with the. First operation then. First operation. So. How do we do? To, on. Thank you. Thank you. Thank you. Thank you. Okay that was the first one face milling. Now we're going to do some repeated the shoulder milling and here we're going to do this pass on the side with 25% of the cutter. We will do this 6 mm depth and then we will do another one but we will do the relief, the 0.5 on the wall and the cutting data is 240 and 0.83 feet. Now we will do another pass. Now we will do another one on this on this side but with more engagement. Currently. Here you can see the line of the 0 .5 wall that we have for the relief. As Gosselin talked about. So yes, back to you, Gosselin. Thank you, Julio. Then as we have just seen in repeated shoulder, there will be a line connecting the first and the second repeated shoulder passes. That is to respect any worn out, early worn out on the unused edge. As we also see in these demos, we used down milling. Down milling is always recommended in the art of milling. That means entering into the material with a thick, cheap thickness and getting out from the material with as thinner as possible in terms of cheap thickness. That will give you the best tool life in all the applications. Then how it is possible to apply such recommendation in down milling, even if there are some holes, some slots, irregular shape on the component. Then we would recommend to apply a trajectory that will tend to apply the milling operation in down milling. Even if there is a hole, it is to apply a trajectory that will go around the hole. When there are some slots, it is to apply a trajectory that goes on one side of the slot and go back from the other side of the slot. Then what about with long overhang? Core mill MF80 can be associated assembled on Ceylon tools adaptators. Ceylon tools adaptators offer modular tools assemblies for different kinds of couplings and a broad functionality range to cover all materials and applications with or without current. Ceylon tools product offer provide solutions from four up to eight times the adaptator diameters. And a standard solution, of course, it is always possible to have some customized solution and such tools. So, when applying a deep or machining a deep pocket with deep access on the bottom of the component, it is preferable to split the milling operation in two or three different steps, accordingly the different overhang that will provide the highest productivity level. So, at the beginning of the component machining will be with a short overhang down to a very long overhang with Ceylon tools solutions. In short or medium overhang, when applying Ceylon tools, it can provide up to 50% gains in productivity, with the longest overhang. The productivity gains will be even higher, up to 300% on productivity with the longest overhang. I am quite curious to see it in action. Rulio, are you ready to run this demo? Yes. And now we're going, first we're going to start with the short one. Again, we're going to do some wavy shape form. We're going to start with the engagement of the cuppler from 20 to 60%, 6 mm depth, 240 and 0.83 in feed. So now we will do a straight pass. As well. And next we're going to, well, all we're going to do is similar as you see here at the bottom of the work piece, but now we're going to use a silent room, a damp adapter. It's this one that we have. We're going to use the same cuppler and 63 in dimension. The speed is 120, same feed, 2 mm depth of cut and 20 to 50% in AE. And the total length together with the assembly for the BT40 will be 314. So it's five times the diameter. So where do you stay for? Don't have them tendance to. And the other one. And the last will be a straight cut as well as we did before with the short one. So thank you very much. I'm back to you guys. Thank you very much. Julio. Thank you. Thank you Julio. Okay, go ahead. Just land, please. Now you see. Tell me. Yeah. If there's any process recommendation you can give to us. Repeat, please. Sorry. If there's any process recommendation you can give to us. Yes, share please. The. Okay. Thank you very much. Okay. We see now others process consideration. The important. You are sharing the just land the video. Yes. Okay. Massimo is okay. The attendees see the presentation process consideration cutter positioning, please. Yes. Okay. I go ahead. Okay. Now we see other process consideration. The important point is to respect some cutter positioning. I mean, when, for example, we have to machine some bosses is dangerous to work directly in the middle in the axial cutter. The bosses in this case we have to when we have thick chip at the axis and big interrupted cut formation is a risk to break the insert. In this case we have to optimize the process in the we recommended to work in a thin chip on exit. This case is we recommended to work in tangential with the cutter. Cutter. I mean the cutter to put in the. Left of the component that we machine to have a better reliable process. Another process consideration is regarding the circular interpolation. Remember that the MF80 is not possible to apply ramping capability. The cutter doesn't work in ramping. We have to work in circular interpolation. I mean in Zed stable position. And for example, when we work internally interpolation, try to avoid to enter directly in the component. If is internal or external. But the recommendation is to have G3 or G2 entering and entering in the in the in the in the tool in the in the components or if we have an internal interpolation. I mean we have to work in G3 in unclockwise for internal. In this case we have a very light entering. Gradually we enter in the in the component gradually and we have a reliable process. When we have external interpolation we have to. Uh, to machine in G2 cycle clockwise to have these benefits in terms of to life. And reliable process. Another point is when we machine internal holes, for example, we have to enlarge some holes. So as you know, when we apply the. Feed the feed table, the formula is RPM multiply FZ multiply number of teeth. But it is it is a linear calculation. When we work in internal or external interpolation. A circular interpolation. We have to adjust the correct feed. For example, when we work in internal. Process we have to apply the compensation. We have to take the diameter of the hole. Minus diameter of the cutter. Divide diameter of the hole. And we obtain one. Number zero virgula something. In the other hand, when we work in external. I mean we have to machine a pin. For example, we have a different formula. The formula is diameter of the pin plus diameter of the cutter. Divide diameter of the pin and we obtain one number. That is one point something in this case. What I want to say is when we work in internally. Sure, we have to reduce something because in the external part of the cutter, the feed is much higher. Is higher compared to the center. The center feed when we when we machine in the the pin, for example, in a in a circular interpolation external. In this case, the internal feed is less. And if you want to respect the correct chip thickness because we have remember we have a minimum. And the maximum, but we and we don't have to go below the minimum chip thickness. In this case, in the pin, we have to increase the feed. Half 50% 60% depends the ratio from the pin and the cutter. Remember, we have to sure we have to adjust. Just learn is up to you. You have to summarize our MF80. Yeah, thank you, Stefan for all these technical points. It is time to summarize what is core mill MF80. So we have seen it is a face milling for roughing and close shoulder milling. For ISO-K and ISO-K material. And in general engineering roughing and semi-roughing application even for some finishing operation. Thanks to the BS parallel land and the surface finish. It can be applied in the most important industry segments such as automotive components, power generation components, pump and valves, but also oil and gas as we previously said. And for sure it is a multi-edge cost efficient solution with a close, I repeat, close to 90 degree entering angle. And that can be particularly appreciated when it is a milling operation on components with a lot of fixture constraints. And it is not possible to have a nice face milling concept applied due to these constraints. And as we have seen also with Cylentools demos. Thanks to that close to 90 degree entering angle. Efforts, machining efforts will be more radially than actually. And that gives a great stability even if the setups of the machine and components are limited. And for the thin floor components, that is really important to have such solution. For fewer details, you can have some information on our website. 3w.sandvic.com. And in the search bar type Coromil MF80, you will get, you will reach this more information on this concept. So, it is time for Q&A session. Let's check if we have any question. Check in the question box. Thank you, Jocelyn. Yeah. Thank you, Jocelyn, Stefano and Julio, sharing this information with us. And now we are at this Q&A session. You can write question at the chat box. I can see already in the chat box some of the questions. I can read. The first question is, if it's not a true 90 degree, but an 89.5 percentage, 5 degree entering angle. Does that mean it is a constant angle? I will talk about that, so I can take in charge this question. 89.5 is almost constant up to 6 millimeter depth. And we've seen that with the picture of repeated passes presentation. Over 6 millimeter or deeper with AP 6 millimeter, the real entering angle, will vary until around maybe 80 degrees, so it will be more flat. And the diameter on the upper side of the insert will be much wider than the lower, lower diameter of the insert. What maybe I didn't mention is that the nominal diameter of the cutter, if it is a cutter diameter 63, is given for this depth of cut of 6 millimeter. So. Thank you, Justin. I hope we answer the questions. The second one. In repeated shoulder passes. Is it mandatory to apply radical compensation? Is it okay for me? Yeah, yeah, yeah. Okay. Thank you, Justin. I think yes, is a good, is a good question. But I think what we recommend is to have the radio compensation. Because if we don't apply, the risk is to use the ABS at the second cutting edge. But it's possible. It's possible to machine in repeated passes without radio compensation is possible. Great. Thank you, Stefano. And the third one. App Max is 9 millimeters. What happens if MF80 is applied for deep rep? Uh, as the Jocelyn said before, I think the recommendation is 6 millimeter. The maximum AP AP Max is 9. But if we have, as Jocelyn said, if we have forging or cast component where the AP is more than 9, it's possible to arrive at maximum 12. Because this is the maximum, but I repeat like in repeated shoulder. If we work more than 9 millimeter, the risk is to use the second BS, the BS in the second cutting edge. But it's possible to apply in the maximum 12. Perfect. Thank you, Stefano. There are no any extra questions. So we can go on with the, uh, closer part. Thank you, gentlemen. Thank you all for your interests and thank you all for joining us today. We are really appreciated spending time with us and we look forward to seeing you in our next webinar or event. We will share recording after the event, so we would like to ask you please fill out our survey. You will receive after the webinar.
