通過平整、拋光、去毛刺等工序提高刀具質量。這其實是刀具在精磨之后，涂層之前的一道正常工序。
何謂刀具鈍化？
通過對刀具進行去毛刺，平整，拋光的處理、從而提高刀具質量和延長使用壽命。刀具在精磨之后，涂層之前的一道工序，其名稱目前尚不統一，有稱“刃口鈍化”、“刃口強化”、“刃口珩磨”、“刃口準備”或“ER（Edge Radiusing）處理”等。
為什么要進行刀具鈍化？
經普通砂輪或金剛石砂輪刃磨后的刀具刃口，存在程度不同的微觀缺口(即微小崩刃與鋸口)。在切削過程中刀具刃口微觀缺口極易擴展，加快刀具磨損和損壞。
現代高速切削加工和自動化機床對刀具性能和穩定性提出了更高的要求，特別是涂層刀具在涂層前必須經過刀口的鈍化處理，才能保證涂層的牢固性和使用壽命。
刀具鈍化的目的
刃口鈍化技術，其目的就是解決刃磨后的刀具刃口微觀缺口的缺陷，使其鋒值減少或消除，達到圓滑平整，既鋒利堅固又耐用的目的。
刀具鈍化的主要效果
刃口的圓化：去除刃口毛刺、達到一致的倒圓加工。
