经PVD涂复的高速钢刀具氮化钛涂层的厚度与刀具寿命的关系,日本通过刨削和车削试验,得出如下结论: 1、经氮化钛涂层的刀具磨损小。 2、涂层厚度对刀具寿命的影响,在断续切削中,明显存在最佳涂层厚度,如图1、图2所示;在连续切削中,涂层越厚,磨损越小(如图3所示),表现十分明显。 3、在刨削
The relationship between the thickness of the titanium nitride coating and the tool life of the PVD-coated high-speed steel tool and the Japanese planing and turning test leads to the following conclusions: 1. Tool wear on the titanium nitride coating is small. 2, the impact of the coating thickness on the tool life, in the intermittent cutting, there is clearly the best coating thickness, shown in Figure 1, Figure 2; continuous cutting, the coating thicker, less wear and tear (Figure 3), the performance is very obvious. 3, in the planing
