Hard alloy cutter passivation process based on erosive wear

At present, many kinds of cutters are provided, and hard alloy cutters are used in a large scale in machining production due to high hardness, high heat resistance and long service life, so that the production efficiency can be effectively improved by passivating the hard alloy cutters. The invention relates to a hard alloy cutter passivation process based on erosive wear, and belongs to the technical field of cutter surface machining. The process comprises the following steps of: step 1, establishing a hard alloy cutter blunt circle radius database; step 2, identifying a cutter to be passivated by an industrial camera and extracting data in the database; step 3, performing passivation pretreatment on the cutter to be passivated; step 4, setting passivation parameters according to the data extracted from the database and the actual situation and starting passivation; step 5, performing post-treatment on the cutter to be passivated; and step 6, detecting the cutting edge of the cutter, packaging and warehousin
