从大型刚性密封磁力泵的阀体密封圈和阀板密封圈的结构特点来看，其密封面上堆焊了硬质合金，硬度很高，加工时进刀量很难把握，实际生产中很难一次加工成形；密封面带有一定的弧度，磁力泵加工过程中需要制作特殊样板，以随时在加工中检验密封面的弧形；密封面的表面粗糙度要求很高，必须有相应的加工工装来保证。为此，我们结合生产实际，采取了以下两方面措施来保证加工要求：改进了磁力泵加工工艺，进行了特殊加工；制作特殊的工装，保证密封面的加工(图\文www.wxjpby.com/)。

From the large rigid sealed magnetic pump sealing ring of the valve body and the valve plate sealing ring structure characteristics, its sealing cover welding hard alloy, hardness is high, the amount of feed processing when it is difficult to grasp, in actual production, it is difficult to a forming; seal with a certain radian, magnetic pump processing need to make a special model, to be in the process of testing sealing surface arc; the sealing surface of the surface roughness of the high demand, must have corresponding processing tooling to ensure. To this end, we combine the actual production, take the following two measures to guarantee the processing requirements: improved magnetic pump processing technology, undertook special processing; production of special tooling, ensure the sealing surface processing.
