    • PURPOSE: To obtain an always stable non-plated part by a simple method by using such a chucking device to be used exclusively which exposes stably one part of a material to be treated having the part or the like requiring no plating to the outside of an electrolyte in performing the treatment.
      CONSTITUTION: A work W is chucked with a chucking jig 9 and is rotated. Negative plating current from the outside is conducted to the work and the grounding electrode part of the material to be treated W where plating is not required or deposition is not desired is stably exposed at all times to the outside of the electrolyte. The electrolyte is discharged under pressure in this state from a circulating tank 2 to a treating station 1 through a circulating pipe 3. The electrolyte is circulated to the station 1 so as to overflow from double or one side overflow gate 5 provided to the station and is returned to the tank 2 while the liquid level over the entire part in the station 1 is maintained stably and constant. A soluble electrode 6 is provided on both sides of the work W or in a cylindrical shape in the station 1 and while the jig 9 is rotated, the work is subjected to plating at a high current density.

    • 目的:为了通过简单的方法获得始终稳定的非电镀部件,通过使用这种专门用于将不需要电镀的部件等待处理的材料的一部分稳定地暴露于外部的夹持装置 电解质进行处理。 构成:工件W用夹具9夹紧并旋转。 对不需要电镀或不需要沉积的待处理材料W的工件和接地电极部分进行负电镀电流,一直稳定地暴露于电解质的外部。 电解液在这种状态下从压力下通过循环管3从循环罐2排出到处理站1.电解质循环到工位1,从设置在工位的双层或一侧溢流门5溢出, 返回到罐2,同时站1中的整个部分上的液面保持稳定且恒定。 在工件W的两侧设置可溶性电极6,在工位1中设置圆筒状,在夹具9旋转的同时,以高电流密度进行电镀。
