The spindle synchronization option G720 synchronizes the shaft

speeds of two or more spindles so that they rotate synchronously

with a gear ratio or a defined offset (see the smart.Turn and DIN

Programming User’s Manual)

In combination with the synchronization (G720) of main spindle and

tool spindle, the new "Hobbing" cycle (G808) is available for milling

external teeth and profiles (see the smart.Turn and DIN

Programming User’s Manual)

With G924, a "fluctuating speed" can now be programmed to

prevent resonance (see the smart.Turn and DIN Programming

User’s Manual)
