摘要： A cutting apparatus includes a blade changing apparatus for changing a cutting blade mounted on a spindle of a first cutting unit and changing a cutting blade mounted on a spindle of a second cutting unit. The blade changing apparatus includes a nut mounting and demounting unit for mounting and demounting a nut in each of the first and second cutting units and a blade mounting and demounting unit for mounting and demounting the cutting blade in each of the first and second cutting units. The nut mounting and demounting unit includes a rotating shaft, a first nut rotating portion fixed to one end of the rotating shaft, a second nut rotating portion fixed to the other end of the rotating shaft, a motor, and a power transmitting unit connected to the motor and the rotating shaft.

摘要： A blade attachment-detachment assisting apparatus includes a nut rotating part having an engagement pin that engages with an engagement hole of a nut, a nut grip part that grips an annular groove of the nut, a housing that supports the nut rotating part rotatably by a predetermined angle, and a lock mechanism. The nut rotating part is capable of advancing and retreating, relative to the housing, to a protrusion position and a fixing position at which engagement between the nut grip part and the nut is kept, and is fixed to the housing with the intermediary of a spring. The lock mechanism includes an inside surface by which advancing and retreating of the nut rotating part are restricted through engagement of the nut rotating part with the housing when the housing is rotated in one direction at the fixing position to which the nut rotating part has been pushed.

摘要： A cutting apparatus includes a cutting unit that has a spindle with an annular cutting blade mounted to a tip part of the spindle through a blade mount, and a determining unit. The determining unit has a second flow path that is connected to a first flow path in a mounter of the blade mount for causing a negative or positive pressure to act on the first flow path, a measuring device that obtains a measured value of at least one of a pressure and a flow rate in the second flow path, and a screw-engaged state determining section that determines that a screw-engaged state of a fixed nut with a boss section of the mounter where the cutting blade is disposed is defective in a case where the measured value when the negative or positive pressure acts on the first flow path indicates an abnormal value.
