How does this compare to our previous R8 spindles? You'll notice a couple of differences right away; You'll gain 1.77 (45mm) of Z axis because the new spindle nose is so short. On a small mill this is important. You can now fit bigger parts. Much better harmonic damping. This can mean faster cuts with better finish and precision.
