HEDELIUS uses liquid-cooled spindles with direct drive, known as motor spindles, in its machining centres. Depending on the substance and material removal in question, high rotation speeds or moments may be required of the spindles. As such, HEDELIUS offers different spindle designs from 8,000 to 18,000 rpm with performance of up to 50 KW, depending on the machining task. Users can chose between SK or HSK versions as an interface. The machines are equipped with a spindle chiller for thermostable precision.
