龙门刨床床身导轨是机床主要部件之一,是相对位置和运动的基准。在更换工作台导轨衬板时,以床身导轨作为工艺基准,可以很容易地保证工作台面的精度和工作台齿条与主传动齿轮传动链的要求。 为了使所更换的导轨衬板与原导轨衬板在精度方面相一致,尽量减少更换导轨衬板的工作量, Planer bed rail is one of the main components of the machine, is the relative position and movement of the benchmark. When changing the guide rail of the workbench, taking the guide rail of the bed as the process reference, it is easy to ensure the precision of the working table and the requirements of the transmission chain of the worktable rack and the main transmission gear. In order to make the replacement of the original rail lining plate and liner in the same precision, minimize the workload of the replacement guide plate,
