当前前欧州共体已规定没有“CE”标志的机床不能进入欧州市场，而且国际市场也对安全防护技术的要求越来越重视。目前，电火花加工机床的最主要技术难关是辐射骚扰，因为它对生产和操作过程的安全、环保影响比较大，在整个国际市场都在倡导“绿色”产品的情况下，作为端子机模具加工的主导设备电火花加工机床的“绿色”产品技术，将是这个行业今后需要解决的难题。
At present, the former European Community has stipulated that machines without the "CE" mark can not enter the market of Euro-city, and the international market also pays more and more attention to the requirements of safety protection technology. At present, the main technical difficulty of EDM machine tools is radiation disturbance, because it has a great impact on the safety and environmental protection of production and operation process. Under the circumstance of advocating "green" products in the whole international market, EDM machine tools as the leading equipment of terminal machine die processing are "green" product technology. It will be a difficult problem for the industry to solve in the future.
