我院在开门办学过程中,针对涡轮盘的加工,研制了75°—45°断屑车刀,经在工厂试用,效果较好,可断成2寸或1尺长的卷屑。刀具结构如图示。刀具特点如下: 1.120°～125°是代替刀具前而上的卷屑槽; 2.B的大小随走刀量改变,走刀量大B应大些,反之则应小些; 3.θ角的大小对断屑效果有直接影响,θ越大断屑越好,要根据被加工材料及切削用量试验选取; Our hospital in the process of open door, for the turbine disk processing, developed a 75 ° -45 ° chip breaking tool, the trial in the factory, the effect is better, can be broken into 2-inch or 1-foot long chip. Tool structure as shown. Tool features are as follows: 1.120 ° ~ 125 ° is to replace the tool before the chip roll groove; 2.B size with the amount of change to take a walk, the amount of large B should be larger, and vice versa should be smaller; The size of a direct impact on the chip breaking effect, the greater the greater the broken broken debris the better, according to the material being processed and cutting test selection;
