传统的手工打磨和抛光方法，包括传统的手工打磨和抛光。这些传统方法不仅不一致，而且在工时、高返工和报废率方面成本高昂。说到做到，成品通常还需要额外的去毛刺和表面处理，如果不加以识别，将导致效率降低和产品失效。绝不能在不完美的条件下接受产品。

When presented with ongoing burr and finish problems, manufacturers have relied on old-fashioned, time-consuming methods that include wire wheels, labor intensive hand work, tumblers and vibratory bowls. These traditional methods are not only inconsistent, but costly in terms of man hours, and high rework and scrap factors. When all is said and done, the finished product often still needs additional deburring and surface refinement, which, if not recognized, will result in reduced efficiency and failed products. Products should never be accepted in a condition less than perfect.
