We have been running sandviks small diameter high feed tools in abrasive steel alloys for several years. They turned out to be by far the most economical way of removing large amounts of difficult to machine material. We will definately try out these too.
Finally, the new successor to the Coromill R210, which is also important and usable for machining stainless steel and titanium alloys, as this geometry really cuts.
If the face milling cutting data is concern at 3183 RPM the average power consumption will be approximately 6,4 KW. So if the machine is capable to deliver that much then for sure the cutting data can be used.
@@erik.with.a.c within reason I don't think it really matters. I ran second shift at a shop using indexables on little Sharp SV2412s and we ran the shit out of them in stainless for 10+ years per spindle
Given that the cutting forces are basically parallel to the Z-axis, I'm not sure if the vibration is more or less damaging than the usual axial forces of side milling. One for the folks in yellow jackets? It's certainly above my pay grade.
I’ve run a lot of feed mills. It can sound sweet and awful. But never had any problems with bearings. But I’ve mostly had high torque spindles hsk100, sk50 and 40. If your spindle is ceramic highspeed I’d take it a lil easier and search for knowledge
most annoying thing about sandvik across a lot of their range is their lack of willing ness to give more cutting edges per insert. Similar high feed tools from competitors give up to 6 cutting edges per insert, at generally a lower cost than sandvik. Favourite sandvik tool is the 725 high speed face mill with 14 edges and the inserts are very durable.
This is why we go for a 2 edge insert! The weakest section of the insert is far away from the main cutting zone/high-stress zone leading to higher security and reliability. The curved cutting edge ensures higher security against notch wear. Machining against a corner/wall will not impact the next cutting edge and leading corner, ensuring equal performance per edge. Effect of using a conventional four-edge concept High cutting stress at the weakest section of the insert leading to lower reliability, especially in ISO S and M applications with notch wear characteristics. Machining against a corner/wall will impact the leading corner resulting in lower performance (tool life) after indexing.
