主轴是机床重要部件,所以主轴的精度也是重要的检测对象,如果机床的主轴不满足要求,就会直接影响机床的加工质量,而我们在生产主轴时,我们要对主轴的静刚度、扭转刚度、轴径径向跳动、轴肩支承面的跳动等等进行校核,只有这些重要物理量满足要求,主轴的精度才能保证,同时主轴轴承也是影响主轴精度的因素。 Spindle is an important part of the machine, so the accuracy of the spindle is also an important test object, if the spindle does not meet the requirements of the machine, it will directly affect the quality of machine tools, and we produce the spindle, we have to static rigidity of the spindle torsional stiffness , The shaft diameter radial runout, the shoulder bearing surface beating and so on to check, only these important physical quantities to meet the requirements, the accuracy of the spindle can be guaranteed, while the spindle bearing is also a factor affecting the spindle accuracy.
