4. Related to the spindle synchronization system for synchronized operation of the main spindle of a lathe with especially opposed main spindles. A high-speed lathe with two spindles facing each other has been put into practical use.In a single lathe, the rotational speeds of the 28 axes must be made equal with considerable precision. For this purpose, the same command is given to both spindle amplifiers, the spindle amplifiers and spindle motors with the same specifications are used, and the machine loads are also the same. However, in reality, perfect synchronization cannot be achieved due to slight differences in characteristics of the spindle motor, spindle amplifier, etc.
