金属材料做应力松弛试验时,所用试样松弛环是偏心的(图1)。现介绍一种简易加工偏心装置。偏心装置(图2)是装在立式铣床的工作台上,底座是利用标准的圆盘台面 When the metal material is subjected to a stress relaxation test, the sample relaxation ring is eccentric (Figure 1). Now introduce a simple processing eccentric device. Eccentric device (Figure 2) is mounted on a vertical milling machine table, the base is the use of standard disc table
