几乎70%的零部件制造误差是由温度波动造成的,特别是大部件以及相应的大机床,因为热膨胀通过长距离的传导就会变得十分明显。往往仅仅几度的偏差就能造成机器和部件较大的形变,以至于制造出来的部件无法使用。通行的解决方法是将机器和环境同时保持在恒定的温度水平,这样可以预先避免机器发生形变。但是这种办法达到满意效果的前提是,必须24小时保持空调运行和机器处于通电状态,否则要恢复稳定的状态,必须花费很长时间。因此,机器的温度调节需
Almost 70% of component manufacturing errors are caused by temperature fluctuations, especially large components and corresponding large machine tools, as thermal expansion becomes apparent over long distances. Often only a few degrees of deviations can cause large deformation of the machine and parts, so that the manufactured parts can not be used. The solution to this problem is to keep the machine and the environment at a constant temperature level at the same time so that deformation of the machine can be avoided beforehand. However, this approach to achieve satisfactory results on the premise that the air conditioning must be running 24 hours and the machine is energized, or to restore a stable state, it must take a long time. Therefore, the temperature of the machine needs to be adjusted
