Hello and welcome to this solid round tools knowledge session. During this series we will cover features, strategies and products relating to solid round tools. As always we start with safety. Safety is our top priority at Sandvik Coromant. Please ensure you're watching this in a safe environment. Be aware of the safety procedures of the building that you're in as well as the exits and assembly points should there be an emergency. My name is Ben Lodge and I'm the product specialist for solid round tools in North Europe. My name is Paul Lugton and I'm the can specialist for North Europe and today you can join us to look at the Gannet plunger. So this is the Gannet plunger and we also we can use the Gannet plunger in sort of various sort of applications ranging from slotting to profiling to pocketing, both rough pocketing and also rest machine in the pocket corners. So we have a full round of project. Can you just explain more about the product spent? Yeah, so as we can see from the slide there, when we're looking at plunging applications, we have a number of indexable products available to us with the 210 and the 215. And then we have the Gannet cutter there where we'll be able to go up to 10 times D in plunging operations. And that's from four to 25 millimetres in diameter. So obviously with these tools we can use them in various industry segments, aerospace, power generation. We can also use them in oil and gas, iron mould and machine tool making. But one component we see a lot of these use of these tools is in bliss propellers. Both obviously from the challenge of material, but obviously the challenge in applications. Quite often they need very long reaching narrow pockets. But obviously that's the sort of materials we're using to tame an HRSA. But what about other materials we use these tools again? Yeah, we can also use these and utilise them in ISOP and ISOM materials. So with the Gannet plunger we've got a lot of options available to us when it comes to the materials that we can apply it in. But now we need to look a little bit more into what makes this Gannet tool a little bit different from all the other products that are available on the market. Sure. Like Ben says, this Gannet tool is very unique in the marketplace. And it needs to be used in a various way because of their uniqueness. You can see on the slide here, you can see that the cutter, unlike a normal sort of end or slot, it's got like a concave middle. And the idea is concave middle when the tools engage at 30% of its diameter, this balances out the load. So you get all the cutting courses going straight up the spindle. And that's what enables us to go to such long overhangs up to 10 times diameter. They still keep really good productivity in application. And how can we get the best out of this cutter? We've talked about the geometry. And where to get the best out of this tool is this sort of various rules and guidelines. And this will, the tool will work in most applications, but what we're going to talk about is how to get the best. So you get the best in the application, most predictable, and also the best tool life. So there's sort of various tips and tricks. Obviously we talked about the 30% engagement. We need to keep ideally around the 30% AE engaged into the material to keep that balanced geometry. And when we step across, if we've got a wide pocket, we would like to step from sort of left to right. So you can see on that diagram there, one, two, three, four. So we're going from left to right. And that's so we can keep the chip thickness thin on the exit. And we ideally need to step over sort of 75% of the tool diameter. So we sort of do those white pockets will zigzag backwards and forwards. And also, ideally we need to do a staircase upwards. After we go forwards back in each level, we need to lift up in Z so we don't contact the floor from the previous cut. We'll explain that in one the next couple of slides. So you can see here, obviously ideally for really deep slots and for narrow slots, obviously horizontal machining is preferred. Because that gets you nice chip evacuation. But obviously we also recommend using sort of CF collets with 316 tools. Or our solid tools come with coolant grooves all the ground and that's so we can get either air or coolant to help evacuate the swath. If possible, it's always best to use that sort of rollout exit so we get that smooth transition. At the floor as well as stepping up in Z. If you can't roll out a cut, what's best to do is just to slow the last say millimetre, two millimetres, just drop the feet. So you get that nice transition in the floor. Obviously because we're stepping over, so that's sort of 30%, the walls would you leave quite sort of reasonably large cuffs. Obviously this is a roughing operation. So we'll need really reasonably large cuffs on the floor. And there's just a rough guide on that screen there. You can see sort of 2.8% of the diameter is the rough plus height left by the tool. So here we can see that application. This method is that we're doing a slow entry, 100% speed. And in this application here we're going to roll out a cut on the bottom. And if we're going to program this, do we have to do something special to get that roll out? You generally have to do something. Some cam systems support it. But generally the easiest way is just to draw a curve. You drive that tool along the curve, roll out the bottom. And then you can either put that in the side or copy or paste the operation to get you a good tool path. But this is our preferred number one method to get you the best tool life. And the reason we roll out is just to move the tool away from the floor on the track. And you can see now we're looking at this just done with a standard drilling cycle. So the tool is going in and out without moving an X and Y. And again, this is still our preferred method of just slowing down when we kick the floor. We are slowing on entry. That's not essential. It's nice. But the slowing on the floor is what's really important. Just age it all up. So this is using a standard drilling cycle that's available in cam packages? That's correct. Yep, this is just a standard drilling cycle. It's just a major resistance to the feed. And what we're doing on this example here is just showing you that you can use just a normal drilling cycle with one fixed speed all the way through. The tool will work, but obviously your tool life will be slightly reduced from the other previous applications. So it just shows you the tool still works well in that application. And we'd see the reduction because we're dragging the tool back at the surface that we've just machined. That's correct then. Yeah, we're dragging the tool up the surface and obviously we're not slowing at all as it sort of interacts with the previous cuts on the floor. So there'll be a slight sort of course of rubbing action there. So what you saw there was that sort of open pocket. We can also use the tool in the closed pocket just doing a single cut through in a straight slot. And you can see on the screen on your screen and we saw it takes the sort of the third cut before you get the full engagement of the tool. That sort of full 30% engagement right away around the tool. And the other thing to bear in mind where you are in this closed slot, as you can see on the far right hand picture, you can't roll out a cut. You've got to just use a standard drilling cycle. So you just got to go in and come back out in the same X and Y coordinates. But again, it's still good to do that slow down at the bottom of the floor that will still help tool life. And now you'll see a sort of an example of that. This is of beta titanium programmed in NX. And you can see this is a 25mm. So we're really long overhang. You can see here we're just using in this application. We're just using the standard drilling cycle going straight in and straight out. And you can see running on the screen we are using that CF-Colix. This is a 316 tool. Using the CF-Colix so you can see the coolant's blasting down the side of the tool. Helping to evacuate the small from the pocket to make sure we don't contact that small thing at all instead of the floor. So with this one we're slowing down at the bottom of the... That's correct then. Yep, the last I think one millimetre we're just slowing the feet right down just before it contacts the floor. And you might be able to hear that in the actual video. So you can just see on that picture on the screen you can just see the sort of what happens at the floor. And then how it sort of overlaps the previous cuts. And you can see the marks on the side because we're not lifting away from the wall. You do get a slight rubbing action on the side. But again, that tool still works. But obviously ramping away when you can or just help the hated tool life. So one other thing to look at. We're going to come into a minute to talk about tools. But it's good to use our solid tools that already have undersized shanks. With our 316 tools it's good to use an application. So either a head on an undersized shank. We do so undersized shanks on all of our ranges. So it'll be like example like a 10 on a 9.7 shank. Or the other thing you can do is use an imperial head on a metric size shank. And that will again give you clearance. Because you need to get clearance from the cutting diameter to the shank. So you don't get a rubbing action like you can see on the screen. So Ben, would you like to tell us more about these tools? Yeah, so first we're going to have a look at the CoralMill 316 products. So we introduced these products in the 18.1 CoralPack. Now this is the the Gannett geometry on our exchangeable head coupling. Diameter range we're looking at 10 to 25 millimeters in diameter. And as we spoke about before, you know this geometry is optimized for components with the narrow slots. Such as the blisk of the impellers. All the deep pockets where we're looking at long overhangs of up to 10 times D. So as well as this Gannett tool, what other sort of tools can we get on these 316 coupling then? I mean, you know, we can see there the benefits from the illustration of the, you know, how versatile the exchangeable head coupling is. You know, we have all the different back ends, whether that be the integrated back ends, you know, the solid carbide, the heavy duty shanks. But you know, on the front end we can also use boring heads and also the indexable milling cutters. So it gives us a lot of versatility with the exchangeable head concept, not only for the Gannett tool, but also for other products within our portfolio. Very good. Very good. And what happens if our standard Gannett tools don't fit the applications? There are other options? Yeah, we have tailor made available to us in the 316 Gannett. So as we can see there, there's a number of different options when it comes to the blank length. We've also got different options when it comes to the grade as well. You know, so we can change the Gannett as you know to customers needs as well as the diameters as well. So we have the metric and imperial options available to us within the tailor made family. So now we're going to look at the Coromyl Plurogannett and this was launching the 20.2 Coropat and it features our 1610 grade. So this is optimized for plunging in HRSA materials and we can see there, you know, these coolant grooves that we spoke about before to help us with this safe chip evacuation. So from this, you know, it helps offer a high productivity and tool life in these HRSA applications. So is that the sort of tool we're using in our blue steel impellers? Yeah, as we said, you know, this is more directed towards those kind of applications. It's optimized for those applications and the cutting data is as well. So as we look at the assortment itself, we can see here that we have the 4 to 16 millimeters diameter tools available as standard. In metric in four and six times diameter. And then we have our made to order available as well in the imperial. So they're in the 316 to 5 8. And as we spoke about before, when we had the 316 tools, we have similar options available to us when it comes to the plurogannett as well. So 3 to 16 millimeters in diameter available and we can go up to 8 times D in a solid tool as well. Okay, and I see there as well available different grades. I guess that suits materials. Exactly. We've got different grades suited for different materials. As we spoke about before, you know, this 1610 grade is optimized for HRSA materials. So if we are looking at other applications, other materials, then we do have grades to complement them as well. So as we look at our competitors on the market, you know, we spoke a lot about the differences between our Gannett tool and we can see the main one on the screen there has been our geometry. You know, a lot of our competitors are using either indexable or solid products as well as exchangeable head in these kind of applications. But because we've got this balance cut due to this geometry on the bottom, we see a really big difference in our product against our competitors in the market. So that would obviously that balance jump to a nervous system, really high sort of times diameters and still get good productivity. Exactly. Productivity and as well as, you know, extended tool life as well. And especially if we look at those strategies that we spoke about before. And with the Gannett, it also gives us a kind of a different direction to looking when it comes to looking at applications. So we can see here, you know, against our competitor, they're using a tracheoid milling method, you know, a very well known method within the market. But looking at a different approach, taking a different approach with the Gannett tool and the strategies that we spoke about today, we can see a massive increase both in tool life, but also see a massive reduction in cycle time. So there we saw an 800% increase in tool life, but a 60% reduction in tool life as well. So it gives us a really good result. And that's where we've talked about before, this sort of four times diameter is the optimal point when you change in the practice of Gannett tool. Exactly. Good. And as we look at our product positioning now, when it comes to solid carbide milling in these kind of applications that we spoke about, you know, we have predominantly our high feed side milling offer when it comes to pocketing or tracheoid milling methods. You know, we have our slot and shoulder milling. So if we are full slotting, we have our, you know, VFD or HD products within that area. And now we have the plunging method as well. So we've got the organic tools available to us both in the Plura and the 316 options. It's a really good selection to cover most applications. Exactly. And it gives us different approaches depending on what the applications are and obviously what the materials are as well. So that brings us to the end of our session today.
