滚压加工,在车轴轴颈的精加工中使用很广,在我们机床制造业中应用还不多,但是滚压所具有的优点是值得我们加以注意与推广的。 滚压加工除了能提高加工物表面光洁度,还能增高表面硬度。由於因滚压所产生的剩余压缩应力存在,因此当零件在受张应力负荷时,剩余压缩应力能抵消部分张 Rolling process, the use of a wide range of machining of the shaft journal, in our machine tool manufacturing industry is not much, but the rolling has the merits that deserve our attention and promotion. In addition to rolling can improve the surface finish, but also increase the surface hardness. As the residual compressive stress generated by the rolling exists, so when the part is subjected to tensile stress, the residual compressive stress can offset part of the Zhang
