i worked a Heidenheim machine at the shop i was at in Sheffeild,Eng.,it was 5 axis like this one.it's hard to run a prog. like this in graphics,so your first cycle can be stressfull.i wonder how many bits they loaded up not using coolant.
definately cooler than the 3-axis HAAS POS's we use
And if your spindle speed, depth of cut and feed rate are spot on there is no need for coolant as all your heat is displaced in your chips and not the tool. I doubt they even had to change inserts during that whole cycle.
heh first of all you machinist dudes are getting way to techincal and second of all that was rad! third what a waste! lol a 120kg block turned into a 3kg helmut wheres the other 117kgs of material removed, hopefully they also have a foundry nearby lol.
