A groove machining apparatus for an insulating spacer includes a cutting blade that is removably fixed to a rotation shaft rotatable around a horizontal axis and movable in a right-left direction and in an up-down direction and mounts for a cassette that are fixed in a loading/unloading position opposing an entrance through which the cassette can be loaded/unloaded and in a working position 180 degrees apart from the loading/unloading position and facing the cutting blade, respectively, on a rotary table. The apparatus includes positioning devices that are respectively located in the vicinity of the mounts to position and fix the cassette to the mounts, and a clamping device that corresponds to the cassette in the working position and presses opposing edges in a front-back direction of a plurality of insulating spacers aligned on the cassette. |
