一、床身自然调平的概念 床身是机床最主要的基础件。调整机床精度时机床床身导轨是测量的基准面。因此床身的合理调平对于保证机床的精度具有决定性作用。所谓“自然调平”是指床身在保证加工精度条件下,靠自重放在调整垫铁上,不紧固地脚螺钉,使之完全处于自然状态下达到精度 First, the concept of natural leveling bed The bed is the most important foundation of the machine. When adjusting the machine accuracy, the machine bed guide is the measuring datum. Therefore, a reasonable bed to ensure the accuracy of the machine tool has a decisive role. The so-called “natural leveling” refers to the bed under the conditions of ensuring the accuracy of processing, by adjusting their own weight on the horn, do not tighten the screws on the ground, so that it is completely in its natural state to achieve accuracy
