数控机床的刀架、工作台,电解磨床的工作台,三维测量器的触头等极低速的进给(5～50mm/min)必须避免不稳现象。为了确定进给不稳现象的有无,可以使用图中所示的检测装置。柱塞8与工作台3一起以极低速向左移动,缸7内的空气通过管道9进入升压器10(密封腔)。升压器内的空气由节流口11徐徐流出。如果8的进给平稳,那么升压器内的气压不变,如果发生进给不稳现
Very low speed feed (5 ~ 50mm / min) of the CNC machine tool turret, workbench, electrolytic grinder workbench, three-dimensional measuring device contacts must be avoided instability. In order to determine the presence or absence of feed instability, the detection device shown in the figure can be used. The plunger 8 moves to the left together with the table 3 at a very low speed, and the air in the cylinder 7 enters the booster 10 (seal chamber) through the pipe 9. The air in the booster flows out slowly through the orifice 11. If the 8 feed smooth, then the pressure in the booster unchanged, in the event of feed instability
