    • A vibration finishing method and apparatus in which the surface roughness and form of a hole in a compound material such as a printed board can be made excellent and the working accuracy of the hole can be significantly improved and the working cost of the hole can be lowered. In the punch pressing device, a compound material is fixed to a lower metal mold having a lower die hole into which a punching tool can be inserted. While the compound material is held between the lower metal mold and a pressing plate and pressed by pressing members provided with the pressing plate having an upper die hole into which the punching tool can be inserted, a minute-vibration of frequency of several ten hertz is applied onto the punching tool and then, the compound material is punched out. After that, the punching tool is temporarily drawn from the hole to be worked in the compound material. The punching tool is re-inserted into the worked hole in the compound material while a non-vibration or the minute vibration of frequency of several ten hertz is applied again onto the punching tool.
    • 能够使诸如印刷电路板的复合材料中的孔的表面粗糙度和形状优异并且可以显着提高孔的加工精度并且可以降低孔的加工成本的振动整理方法和装置 。 在冲压装置中,将复合材料固定到具有下模具的下金属模具中,可以插入冲压工具。 当复合材料保持在下金属模具和压板之间并且通过设有具有上模孔的压板的按压构件被按压时,可以插入冲压工具,几十赫兹的频率的微小振动是 施加到冲压工具上,然后将复合材料冲压出来。 之后,冲孔工具从复合材料中的待加工孔暂时拉出。 将冲压工具重新插入到复合材料的加工孔中,同时将几十赫兹频率的非振动或微小振动再次施加到冲压工具上。
