The invention provides a cutter coating process and equipment, and relates to the field of metal surface treatment. The cutter coating process comprises the following steps: pretreating a cutter substrate; performing gas ion cleaning on the tool substrate; carrying out magnetron sputtering on the metal target material by adopting a high-energy pulse magnetron sputtering technology to form metal ions, and carrying out etching cleaning on the tool substrate by matching with the pulse control metal ions of the pulse bias; and a metal carbide layer and a carbon film layer are sequentially deposited on the surface of the tool substrate, and the thickness of the metal carbide layer is not larger than 500 nm. After the tool substrate is subjected to gas ion cleaning, the tool substrate is subjected to metal ion etching cleaning, the binding force between the tool substrate and the carbon film layer can be effectively increased, and therefore the thickness of a metal carbide layer is reduced on the premise that it is guaranteed that the tool substrate and the carbon film layer are stably combined, the thickness of the metal carbide layer is not larger than 500 nm, and the tool substrate is not prone to being damaged. The cutting edge is prevented from being blunt due to over-thickness, and the sharpness of the cutting edge is ensured.
