Because the size in the circumferential direction is limited, the corrugation cannot be too wide, and meanwhile, the main stress direction of the saw blade cutting and grinding work is in the circumferential direction, the saw blade cutting and grinding work is basically vertical to the corrugation, and no circumferential support exists, so the strength of the corrugation is low; if the circumferential width of the corrugations is large, the sharpness is reduced.
