The double chip breaking table is the first chip breaking The side wall 16 of the table 15 and the protrusion 17. When performing medium depth-of-cut machining, when chip breaking, only the first chip breaking table 15 can be used as the main chip breaking component to meet the needs of workpiece chip breaking. In the deep cutting process, when the blade breaks the chip, the workpiece is first subjected to the chip breaking effect of the first chip breaker 15, but due to the large depth of cut, the first chip breaker 15 cannot effectively break the chip At this time, the blade uses the side wall 16 of the protrusion 17 to play the effect of the second chip breaking table, and also has a good chip breaking effect when machining at a large depth of cut, and functions as a double chip breaking table. When the center hole is pulled out to the outside of the workpiece for finishing, the "half-moon-shaped" protrusion 17 can perform good chip breaking, and at the same time, the range of chip breaking of the blade is further expanded, so that the blade Whether roughing or finishing can get a good chip breaking effect.
本发明的一种用于不锈钢法兰车削刀片，在第一断屑台15的两侧，均设置有大面积的大容屑槽，在配合断屑台结构的设计，使得刀具在加工中的热量大部分随着切屑的排出而带走，从而提高刀片的耐磨性和使用寿命的同时保证了被加工件的表面质量。The invention is used for a stainless steel flange turning blade.
