So nice to see dmg equiped with sandvik. There is so many company whos bought dmg and other expensive toys and then works with indian and chinese toolholders and tols
This strategy looks like it has the potential to greatly increase tool life because the corners of the tool would be used equally and for only half of the cutting time. Compared to an ever-widening right-to-left strategy where one corner may take a majority of the wear. I suppose it depends on workpeice rigidity. Eager to try this, what do the internet machinists think?
depends on the part, material, depth of groove, width of insert,... some materials don't form chips so easily, some will form thick strings that will jam in the groove, causing overheat of the insert, also i wouldn't groove stainless or similar materials this way since the resistance could cause the ring to vibrate bit too much and break the insert, also this way the sides if the insert are in constant contact with sides of the groove, causing friction which means heat, also the bottom diameter of the groove holds "the rest" of the unsupported workpiece, means that if you do one groove that ends on small diameter and then continue second that is on the unsupported side of the part, things may get nasty really fast
You can run higher feed rate where the material is narrower than the insert Without the blade bending to one side whilst maintaining perfect chip control
