A milling unit (BAE) is needed to work on work pieces (milling, drilling, engraving). The milling unit is mounted to the Z table of the machine. Main component of a milling unit is the mostly electrical powered spindle motor.
Collets with different diameters are used to fix the milling tool to the milling spindle. Most of our spindles are equipped with a vacuum cleaning adaptor. Professional milling units are connected to the safety system of the machine.
