The paper presents the results of a study on the resistance of VOK-60 cutting ceramics when processing hardened steel workpieces made of 45 steel of different hardness 45 HRC and 54 HRC. Tool life of a cutting ceramic insert when machining a harder workpiece by 41 & # 37; higher than when machining a less hard workpiece. A microstructural analysis of the damageability of the working surface was carried out and a mechanism for wear of the cutting plate was established. The reasons for the faster wear of the plate when processing a workpiece with a lower hardness are determined.
