Cutting knife wheel

The utility model relates to a cutting knife flywheel, which comprises a cutting part positioned on the periphery of the cutting knife flywheel, the radial section of the cutting part is V-shaped, a plurality of first grooves are arranged along the cutting part, and second grooves are arranged on the inner walls of the first grooves. The plurality of first grooves are formed along the cutting part of the cutting knife wheel, and the second grooves are formed in the inner walls of the first grooves, so that when the first grooves cut into glass, the second grooves can improve the sharpness of the first grooves cut into the glass, the first grooves can cut into the glass more easily, and the problem of poor cutting or knife sliding is solved. 本实用新型涉及一种切割刀轮，其包括位于所述切割刀轮外缘周向的切割部，所述切割部的径向截面呈V型，沿所述切割部设有多个第一槽，所述第一槽的内壁设有第二槽。本实用新型沿切割刀轮的切割部设有多个第一槽，在第一槽的内壁设有第二槽，在第一槽切入玻璃时，第二槽能够提高第一槽切入玻璃的锋利度，促使第一槽更容易切入玻璃，克服切入不良或者滑刀问题。
