大型数控落地镗铣床滑枕主轴精度悬垂补偿的研究

摘要

在大型数控落地镗铣床的使用时，采用电液比例阀控制前吊索油缸，来实现滑枕伸出不同位置以及采用不同重量附件镗铣头时的悬垂补偿。应用西门子840Dsl数控系统的功能，实现简化补偿数据存储方式，对电液比例阀的线性化补偿控制，从而达到提高加工精度的目的。%When large CNC floor type boring and milling machine is used , electro-hydraulic proportional valve controls the front sling cylinder to help ram extended to achieve different locations and hanging comprehension . Siemens 840Dsl application of numerical control system is applied to simplify compensation data storage, linear compensation for electro-hydraulic proportional valve control , so as to improve the machining accuracy purposes .
