PrimeTurning in action at 3DTechDraw

- Making use of the latest technology is what we do at 3DTechDraw, so we had to test the Sandvik Coromant PrimeTurning. What you see here is a rough cut video of the first part we are using the PrimeTurning on.
Resulted in a reduction of the overall production time from 8 minutes to 5 minutes and 30 seconds. On top of that and most important to us we have seen a tool life increase from 3-4 pieces to over 20 pieces for each insert tip.
Cutting parameters: 187m/min - Ap 2.5 mm - 0.91mm/rev
Material: 42CrMo4 +QT
The part that is being produced is for the VDZ Truck Towing system, that was developed by us in coöperation with VDZ Systemen.

(Sometimes the sound is a little off, due to the GoPro and it's stand. Sorry for that.)
That poor GoPro lol. Nice programming!
Thanks. Yes the go pro go it bad! Had to change the housing after this video. :p
LOL.Well Worth it.
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 ;)
Nice camera angle.
It looks like the coolant is only from under the insert... for sure I'm wrong but...
No you are right. The coolant comes from the underside of the insert not the top.
Thanks for so fantastic application, can you inform us abut the cutting parameters, please?
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.
@@3DTechDrawCulemborg what insert do you run ? I got some 34 cr ni shafts that I make that needs alot of material removed
So is prime turning just reversing the feed direction or is there more to it than that?
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.
Man, it's just raining chips. Did you run this part previously to owning the coroturn prime B style? If so how does tool life and cycle time compare ?
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.
Those are some amazing results!
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 thanks for all the replys Gave you a subscribe, if you ever check out my channel I'd be curious to your feedback. GL in machining man.
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.
Bit of chatter on the tailstock end there
Correct. That was solved when we clamped the steady rest onto the tailstock.😉
It seemed more waste of material than necessary. Too huge of raw dia.
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.
