Hello and welcome to this short knowledge session. My name is Paul Campbell and I'm the turning specialist at Sandvik Coromant. Today I will share a short presentation about our two new HRSA grades GC 1205 and GC 1210. Our two new grades are quite unique which definitely bring the manufacturing process to a new level in terms of machining security and productivity. In the aero engine turning arena there are many different turning solutions. Ceramic and carbide inserts are mainly used. This is most evident in the last stage machining and the intermediate stage machining. We have developed and launched two new grades called GC 1205 and GC 1210. But these grades are not just excellent in the aerospace sector they're also very strong in other materials and other industries like the medical area where you have cobalt chrome. This is a commonly used material and this GC 1205 and 1210 are extremely versatile in both areas. The grade offers excellent flank and adhesive wear resistance which increases tool life and productivity. Adding the use of higher cutting speed without any compromise in component quality. We will certainly increase your output and drive down your costs when you apply these two new grades. The features and benefits are it's well it's a hard fine grain substrate and that gives you excellent flank and notch wear resistance which is key when machining these type of materials. Also edge line security that delivers a constant and predictable tool life which is very very important in both medical and aerospace applications. Optimizing cutting edge integrity and reducing insert flaking. It's a unique substrate with a PVD coating that allows significant increase in the cutting speed. The GC 1205 is the finishing grade for applications in the last stage machining but also intermediate stage machining when the depth of cut is below the nose radius. The recommended cutting speeds are between 30 and 100 meters a minute and the feed rate is between 0.1 and 0.15 millimetre per rev so it's quite an open area very versatile giving very good strong productive cutting data. The GC 1210 is an intermediate stage machining for non-machine services when the depth of cut is above the nose radius. It's a compliment to GC 1205 when extra toughness is required. The recommended cutting speed for this type of application will be between 40 and 80 meters a minute and with a feed rate between 0.1 and 0.35 This obviously depends on machine stability, the component and also the depth of cut so it's quite an open envelope for the cutting data. So both grades are PVD coated inserts. The main difference in the two being that the 1205 has a new coating with good addition to flank wear resistance and the 1210 has a coarser grain coating which is better to protect against crater wear. Hence it works better in the medium machining area with the higher feed rates. The application area is in the ISO-based, typically aged nickel based heat resistant super alloys and materials typically such as Inconel 718 for both aero engine components and power generation turbines and as I said earlier for medical implants in the medical industry it works excellent on cobalt chromes. We have all the product families covered in the new grades. For all the common insert shapes, all the geometries, it is very versatile and a very comprehensive program for heat resistant super alloy turning. The 1205 and the 1210 cover a large application area. They complement each other in the last stage machining and intermediate stage machining areas. The working area is in the mid-range cutting speeds, right across the last stage to the first stage for all machining applications. So it's very broad and it covers all areas of machining within aero, medical and gas turbines. So here we can look at the 1205 versus 1105. The 1205 has better notch wear resistance than 1105. The 1205 has better flank wear resistance than 1105. The 1205 has up to 200% increase in tool life when evaluated in the surface integrity tests. When we look at the 1210 versus our existing 1115 and 1105, the 1210 has shown to have more than 50% increase in productivity over the existing old grade 1115. The 1210 shows a clear advantage over 1115 and 1105. In terms of crater and wear resistance. The 1210 offers more than 50% increase in tool life and 30% increase over 1105 in productivity. Both are clearly outstanding and better in the market. Here we have another customer case study where we've achieved 100% increase in tool life. The material is Inco 718 and the tool life was six parts per edge with a competitor insert. And with the new 1205 we achieved 12 parts per edge. A massive increase of 100% in tool life reducing costs. Here's another test. This test was against our old grade GC 1115. We ran the test of the same data but increased the tool life from 7 to 11 parts. This gave us a 57% increase in tool life. So in this test again you can see it's against our old grade with 1105 and with the new grade 1210. We ran the test of the same data but in this one we increased the tool life from 1 to 3 parts per edge. Giving us a 200% increase in tool life. In this test we ran our old grade 1115 against the new 1210. We ran this test of the same data but increased the tool life from 1 to 5 parts per edge. This gave us a 400% increase in tool life. As you can see in the image how much better the edge line looks after 5 parts. So you can clearly start to see with the new grades we're offering more parts per edge. More contact time, more tool life, better productivity. Clearly a big improvement in our grades out there on the market. Thank you for listening to this short webinar. Please contact your local Coromant engineer if you have any more questions about either of the grades GC 1205 and GC 1210 in HRSA applications. Thank you.
