对于需镀硬铬的机械零件,为保证图纸设计的尺寸公差要求,可以先行加厚镀铬层,再进行磨削加工达到图纸尺寸要求;也可以由电渡工艺本身控制,使得到一定厚度的镀层,不再进行加工即能准确达到图纸尺寸公差范围。后者称为尺寸镀铬。显而易见,两种工艺对比,无论生产效率、原材料利用、能源节约、工时消耗,尺寸镀铬都具有明显的优点,值得认真予以重视,尤其是批量大、任务急时更显示了它的优越性。
For the mechanical parts to be hard chrome plating, in order to ensure the dimensional tolerance of drawing design requirements, thick chrome layer can be applied first, then the grinding process can meet the requirements of drawing size; it can also be controlled by the electroplating process itself to obtain a certain thickness of coating , Can no longer be processed to accurately reach the size tolerances drawings. The latter is called chrome-plated. Obviously, comparing the two processes, no matter whether the production efficiency, raw material utilization, energy saving, working hour consumption, and size chrome plating have obvious advantages, it is worth to be taken seriously seriously, especially when the batch size is large and the task urgency is more demonstrating its superiority.
