经济型数控化改造中主轴部分控制的设计

Control system design of spindle in economical CNC transformation

目前在普通机床经济型数控化改造中,改造后主轴的精度、刚度以及可靠性都直接影响机床的使用性能。为使改造后主轴达到预期控制功能,保证主轴运转的可靠性,文章阐述了一种采用变频器对主轴进行控制的工程实践方法。

In general machine tools economical CNC transformation , the accuracy , rigidity and reli-ability of the spindle directly affect the performance of the machine after transformation .In order to a-chieve the desired control function to ensure the reliability of the spindle running , the paper describes an engineering practice method using the inverter to control the spindle .
