年近来,带小孔和微孔的制品、微型制品薄型和超薄型零件有很大的增长。直径小于1mm的孔和面积小于1mm~2的异型孔属于小孔,直径小于0.1mm的属微小孔,厚度在0.1~0.05mm为薄型零件,厚度在0.05mm以下的为超薄型。制造这类零件,加工微孔及其它小尺寸的结构单元、统称为微细工艺。 在机器制造实践中广泛运用了微孔的压力加工法,这种工艺过程,是以一系列工序在
In recent years, the products with small holes and micropores, micro-products thin and ultra-thin parts have greatly increased. The holes with a diameter of less than 1mm and the holes with an area of less than 1mm ~ 2 belong to small holes whose diameter is less than 0.1mm. The thickness of the holes is 0.1 ~ 0.05mm and the thickness is less than 0.05mm. Manufacture of such parts, processing of micropores and other small-size structural units, collectively referred to as the fine process. Widely used in the machine manufacturing practice microporous pressure processing method, this process is based on a series of processes in the
