No white power occurring on soldered surface or surface of the components , no moisture absorption 焊锡表面和零件面无白粉产生、无吸湿性。
When the machining tools is perfected , it can process all of quadric curves and high degree curves with high surface form precision . at the same time , the its structure is very simple processing size range is large and its efficiency is high , so it will greatly reduce the cost of processing of aspheric parts 该机床完善后,可加工所有二次曲线和高次曲线,并能保证较好的零件面形精度,该机床结构简单,加工尺寸范围大,加工效率高,将会大大降低非球面加工的成本。
