在我厂使用 C620-1普通车床进行高速切削当中,成功地应用了小月牙洼负倒棱90°车刀。这种车刀形状如图。它的特点为:(1)由于具有20°负倒棱,所以可提高刀具耐用度和刀尖强度;(2)刀刃附近有一小月牙洼,保证了断屑,同时可以大幅度地增加刀具重磨次数;(3)刀具有10°刃倾角,因而提高了刀具的耐冲击性能;

In our factory using C620-1 ordinary lathe for high-speed cutting, the successful application of the small crescent-depression negative chamfer 90 ° turning tool. This lathe shape as shown. Its features are: (1) Due to the 20 ° negative chamfering, the tool durability and tip strength can be improved; (2) There is a small crescent depression near the edge to ensure chip breaking, and at the same time, the tool can be greatly regrind The number of times; (3) the knife has a 10 ° blade inclination, thus enhancing the tool’s impact resistance;
