汽车前轴两钢板托表面平面度要求不大于0.5mm,并与两主销孔的轴线平面夹角为88°±15′。由于两钢板托为冲压件,焊接在前轴管上存在焊接变形,再加上工装的定位误差,往往达不到图样要求。为了保证产品质量,需要对钢板托表面进行切削加工。在外厂,两表面一般在专用铣床上加工,而我厂没有专机,为了利 Automobile front axle two plate support surface flatness requirements of not more than 0.5mm, and the two main pin hole axis plane angle of 88 ° ± 15 ’. As the two plate care for the stamping parts, there is welding on the front axle tube welding deformation, coupled with tooling positioning error, often do not meet the design requirements. In order to ensure product quality, the need for steel plate surface machining. In the factory, the two surfaces are generally processed on a special milling machine, and I plant no special plane, in order to benefit
