Cable insulation layer lossless cutting device

The utility model discloses a cable insulation layer lossless cutting device which comprises a hob and a cutter which are used for cutting a cable insulation layer, and the hob is used for cutting the cable insulation layer in the direction perpendicular to the axis of a cable. The cutter is used for cutting an insulating layer of the cable in the direction parallel to the axis of the cable. According to the technical scheme adopted by the utility model, the insulating layer at the end part can be reserved so as to ensure that the conductor at the end part is not loosened and the cable conductor is not damaged, and the potential safety hazard in the sample preparation process can be eliminated. 本实用新型公开了一种电缆绝缘层无损切割装置，包括用于对电缆绝缘层进行切割的滚刀和切刀，其中，滚刀用于沿垂直于电缆轴线方向对电缆的绝缘层进行切割；切刀用于沿平行于电缆轴线方向对电缆的绝缘层进行切割。本实用新型所使用的技术方案，不仅可保留端部绝缘层，以保证端部导体不松散、对电缆导体无损伤，且还可消除制样过程中的安全隐患。
