断屑,通常采用的方法是在车刀前面磨一凹糟。这种方法的缺点是:既降低了刀头的强度,又增加了硬质合金的消耗。为此,我厂曾参考了国外资料,设计出几种附加式独立调整的断屑器。这几种断屑器经实际使用证明,效果比磨凹槽的方法好。但也存在一个缺点,即工作时,断屑器应随着切削用量的改变而加以调整,不仅使辅助工时增加,而且应用也不太方便。针对这个缺点,我们改进了一种自动调整的断屑器。自动调整断屑器的构造图中1是断屑器主体,用螺钉固定在车床的四方刀架上。2是主轴,装在主体1的孔内,并用螺帽3和像皮垫圈4固 Broken bits, the usual method is to wear a concave in front of the turning tool. The disadvantage of this method is that it not only reduces the strength of the cutter head but also increases the consumption of the cemented carbide. To this end, our factory has made reference to foreign information, designed several additional independent adjustment chip breaker. These types of chip breaker proved by actual use, the effect is better than grinding groove method. However, there is also a disadvantage that when working, the chip breaker should be adjusted with the change of the cutting dosage, which not only increases the auxiliary working hours, but also is not convenient for application. In response to this shortcoming, we have improved an automatically adjusted chip breaker. Automatic adjustment chip breaker structure diagram 1 is the main chip breaker, with a screw fixed on the lathe square turret. 2 is the main shaft, mounted in the hole in the body 1, and nut 3 and leather washers 4 solid
