dud try 1040

holy shit

if there's drilled hole on the surface, cbn is easy to crack. cbn is very nice for hardened steel. we have lot of steel around HRC 50. but problem is there're too many holes on the surface....... knive is very easy to crack....

How many SFM in Cast?

[Purloise38]

@levisalo Will get back to you on that one. Have to check the data...

PCBN has very high abrasion resistance; works phenomenally well on cast iron and steels above 45Rc.

[JoeyRomano]

what is the cutting speed for cast iron using CBN inserts?

[cumulo25]

cbn is utrahard (the only thing harder than CBN is diamond). so it's an ideal cutting material

[cumulo25]

looks like.. wait I see it... at 0:42 ... it's a car brake

[kawasakikillerr]

it is. its a rotor. i guess its heat treated enough to need cbn to finish it.

[ahmetozgurergin]

actually whole operation is made by cbn. because of high surface speed of cbn inserts.

nice
