活柱筒是HZWA型微增阻摩擦式金属支柱的关键部件。它的制造要求较高,特别是两摩擦面1:1250_(-250)~(+150)的斜度直接影响支柱的承载曲线及使用性能。在活柱筒的制造工序中,加热轧斜度是难度较大的关键工序,容易出现废品,需要严格检查,因此活柱筒的检测工作量较大。一般常用的检测方法是用分厘卡(百分尺)测量活柱筒 The column is a key component of HZWA type micro-resistance friction metal pillar. Its manufacturing requirements are high. In particular, the slope of 1: 1250 _ (- 250) ~ (+150) of the two friction surfaces directly affects the load-bearing curve and the serviceability of the pillar. In the manufacturing process of the column, the heating of the rolling gradient is a more difficult key process, prone to waste, the need for strict inspection, so the detection of the work of the cylinder larger. Commonly used method of detection is to use Centimeter (centimeter) measuring cylinder
