脉冲滚压器在加工铝合金、青铜等材料衬套中已有较普遍的应用,但在大型铸铁箱体孔的精整加工中却未见使用。脉冲滚压器滚压铸铁孔时,通常都产生针孔麻点,液压表面有鳞刺产生,因此,也就限制了这种液压器的应用。 普通车床床头籍主轴承孔精度与光洁度要求较高,由于此孔长径比较小 Pulse roller in the processing of aluminum alloy, bronze and other materials in the bushing has been more common applications, but in the large cast iron box hole finishing process has not seen use. Pulse roller rolling iron hole, usually have pinhole pitting, hydraulics have spines on the surface, therefore, also limits the application of this hydraulic. Ordinary lathe bed main bearing hole precision and finish requirements of the higher, due to the small diameter of the hole is relatively small
