It looks like this machine has an automatic tool changer, I wonder why you are not using a more rigid tool first like a DNMG to remove most of the material faster and then finish with this profile tool. Then again it was interesting to see how you solved the chipping issue.
yes you can cut this part faster if you want. But you can use the finings if you have a dedicated groove. Dynamic turning mostly the fastest way to cut grooves. Its anyhow a efficient easy to program with CAM and you need just one tool. And with high pressure coolant you can push hard on the cutting speed. but this is not so nice to watch 😉
What will u do with a more tough material like 235N (very soft, chips don't break) 1.4404 or 1.4571? The Problem here is just the wrong tool. By adjusting the cutting parameters, u can solve it in a reasonably material like 355, but u would be much faster and safer with the right toolgeometry, one or two deep cuts with a cnm* geometry and the undercut/finish with a d or v geometry. 2 times faster and full control over chips and finish.
it works also nice in stainless material. This technology comes from aerospace parts. They cut all the tough stuff with it. Inconel hastelloy etc. If standard inserts work use them of course. But you can remember this when the standard insert don`t work. once we changed almost a complete process at the customer to round inserts because SNMG and CNMG didn´t came close to the performance in very hard forged parts. Of course with bigger inserts 12 and 16mm RCMT and coolant. cheers
@@machiningmaniacs4131 There are a lot different stainless steel-sorts, some are easy to cut like mild steel, others are like molten wires. And this is no special "technology", its just turnig with a grooving tool like our apprentices do on their machines without atc.. It takes a lot of time and if your parts go more filigran or the clamping situation is not this good, u will face problems with that long cutting edge. But, if it works good enough for you, im good with it. Go on :)
its not needed but it works great, if you have chip issues they have to be solved dry. Than you can add coolant for maximum tool live. Sometimes coolant is also negative for the chip control.
