为了提高加工精度,分析加工误差产生的原因,需要测定工艺系统的刚度。我们在沈阳第一机床厂的 CA 6140普通车床上,用“车床三向力静刚度测定仪”及“DGB-5型电感测微仪”通过P向车床加载,测定各部件的变形情况(图1)。 当表座吸在床身导轨上,测头顶在方刀台A面时,则出现图2所示 In order to improve processing accuracy, analysis of the reasons for machining errors, the need to determine the stiffness of the process system. We are in the Shenyang Machine Tool Works CA6140 ordinary lathe, with “lathe three-force static stiffness tester” and “DGB-5-type inductance micrometer” by P to the lathe load, the determination of the deformation of various components (Figure 1). When the table seat sucked on the bed rail, the probe at the top of the knife side A, then appear as shown in Figure 2
