部件间相互作用的稳定性及其相对位移轨迹的不变性是决定金属加工机床技术状态完好性的最重要指标之一,并且是在给定生产能力条件下决定金属加工机床精度的一个最重要指标。在机床工作时,或早或迟发生的各种损坏可分为两组:在部件内零件的磨损和损坏,不破坏部件间相互作用的正确性,但在许多情况下,由于磨损零件相互作用时产生的振动而使机床的精度丧失;部件内基准件工作表面的磨损,破坏其相对位移的初始轨迹,并直接使机床精度或生产能力丧失。从上述情况出发,为保持机床技术状态的完好性而进行的所有修理可分为二类: 一类修理是更换或修复机床某些部件总成中的零
The stability of the interaction between components and the invariance of their relative displacement trajectories are one of the most important indexes that determine the technical status of metal working machine and are the most important index that determines the precision of metal working machine under a given production capacity . In the work of the machine, sooner or later, various types of damage can be divided into two groups: parts in the parts wear and damage, without undermining the correctness of the interaction between components, but in many cases due to wear parts interaction When the vibration caused by the loss of the accuracy of the machine; parts within the reference surface of the workpiece wear and tear, destroy the initial trajectory of its relative displacement, and directly to the machine accuracy or loss of production capacity. From the above situation, all the repairs to maintain the integrity of the machine tool state can be divided into two categories: one type of repair is to replace or repair some components of the machine tool zero
