They are in the description. But here again: Cutting parameters: 187m/min - Ap 2.5 mm - 0.91mm/rev Material: 42CrMo4 +QT Later we upped to 200m/min - Ap 2.5 - 1mm/rev. and that ran great too.
Yes we did! Total part cycle time went from 8 minutes to 5 minutes and 30 seconds. (Didn't clock the roughing only) Tool life went over 600% compared to the previous tool.
Yes! We were amazed. Even when we upped the cutting parameters to : 200m/min - Ap 2.5 - 1mm/rev tool life didn't seem to be changing. It's more your gut feeling telling you to now really change the insert, not that it's been completely worn like it was with the previous tool.
3DTechDraw Wait...whaa? There should be specific data on when to change a cutting tool. Not "gut feeling". Now I want to call my Rep and cancel my test tooling.
there are special insert for it and yeah it is that... reverse feed a bigger area of engagement stuff like that go to the sandvik channel they have a video on that topic... we use this tec now and it's so stuipidly fast!
In practise it looks like a DCMT insert just going the other way. But it's a little bit more complicated than that. It has a special holder and insert to make this a viable solution. But once you have the tool you can go crazy feeds with short chips and a very long tool life.
I've done similar with a bmpcc and my workaround was to tape a flat sapphire watch crystal from Esslinger over the lens. Metal is no match for sapphire when it comes to scratch resistance ;)
Actually the raw diameter is also the finished diameter on the top of the part. Which isn't very long compared to the length of part indeed. But the biggest diameter dictates the raw stock even if it's short.
