一、概述机械制造过程中,要得到较精密的内外圆柱面,一般采用磨削与研磨加工,但是生产率低,而且在加工有色金属或其他硬度铰低的零件时,易使磨粒陷入表面而产生烧伤软化等缺陷,严重影响零件的使用寿命。为此,近来国内外对精密冷辗工艺进行了一系列的试验研究,在某些场合下并已成功地用于生产。冷辗工艺的实质,广义来说:就是在金属或者合金
First, an overview Mechanical manufacturing process, to get more precise cylindrical surface, the general use of grinding and grinding, but the low productivity, and in the processing of non-ferrous metals or other parts of the hinge hardness is low, easy to get into the surface of the abrasive Resulting in burn softening and other defects, seriously affecting the service life of parts. To this end, the recent domestic and foreign precision cold rolling process conducted a series of experimental studies, in some cases and has been successfully used for production. The essence of cold rolling process, in a broad sense: that is, in the metal or alloy
