问:CA6150和CA6140型车床主轴在高转速(1400r/min)时,床头箱为什么会跳动?邯郸张树元答:CA6150和CA6140型车床是我国的新产品。设计先进,结构合理,操作方便,加工质量和效率优于其它车床。那么,为什么会产生床头箱跳动呢?一、影响床头箱跳动的主要因素1.高转速引起的跳动原因是主轴、卡盘、工件的动平衡不好。动平衡的好坏是取决于转动零件的重心与旋转轴的轴心是否重合。若不重合,高速旋转不平稳而引起跳动。
Q: Why does the bedside box bounce when the CA6150 and CA6140 lathe spindles rotate at high speed (1400r / min)? Zhang Shuyuan, Handan Answer: The CA6150 and CA6140 lathe are new products in our country. Advanced design, reasonable structure, easy operation, processing quality and efficiency better than other lathes. Then, why the bedside box bounce? First, the main factors affecting bedside bounce 1 high-speed bounce caused by the spindle, the chuck, the workpiece dynamic balance is not good. Dynamic balance is good or bad depends on the rotation of the center of gravity and axis of rotation of the shaft coincide. If not coincident, high-speed rotation is not stable and cause beating.
