我所进口一台提高精度卧式加工中心,其结构见示意图1。 在测量工作台面对y轴(主轴头上下运动方向)的垂直度时(包括纵横两个方向)与制造厂家发系了分歧。制造厂家精度检验单上只作了原则上的思定,如图2所示:在y轴方向l长度上用圆柱角尺测量垂直度,a向:0.01/l, b向 : 0.01/l。 制 I have imported a horizontal machining center to improve accuracy, the structure shown in Figure 1. When measuring the verticality of the workbench facing the y-axis (the direction of the spindle head up and down) (including both vertical and horizontal directions), it was disagreement with the manufacturer. The manufacturer’s accuracy checklist is made on the principle of thinking, as shown in Figure 2: Length in the y-axis direction l vertical square with a square measure, a to: 0.01 / l, b to: 0.01 / l. system
