Magnetic-bearing spindles

Machining 4.0

KEBA has been developing and selling magnetic-bearing systems for more than 20 years, and their continuous evolution has brought about the revolution of the machining sector. With their magnetic bearings, LeviSpin drill spindles can produce micro-movements on 5 planes. This makes it possible to oscillate the spindle shaft and thus generate a targeted chip break, to perform orbital movements, to move the shaft parallel, or to tilt the shaft. This produces numerous benefits.

6D technology in the drill spindle
The term 6D refers to the 5 degrees of freedom of the magnetic bearing in space plus the rotational movement of the shaft. The literature also uses terms like vibration-assisted machining, vibration-assisted drilling or vibration drilling, but these only offer some of the benefits listed below.
