我厂生产的东风—12型手扶拖拉机,它的主要零件有变速箱,传动箱等多种壳体零件。加工工序多,精度要求高,尤其是簿壁壳体零件的端面加工,一直是工厂最为关心的问题。过去我们采用标准端面铣刀加工簿壁壳体零件端面时.由于标准端铣刀刀齿分布,轴向在同一平面上,径向在同一园周上,在加工时同时参加切削齿数的铣削深度a_P 都是一致的,因此所需切削力较大,工件极易产生振动。工件表面粗糙度,平面度
I plant the production of Dongfeng -12 walking tractor, its main components are gearbox, gearbox and other shell parts. Many processing steps, high precision, especially the shell wall parts processing of the face, the factory has always been the most concerned about the problem. In the past when we use the standard face milling cutter shell wall parts when the end face of the standard end milling cutter distribution, the same axial direction in the same plane, the same radial in the same week, while processing in the number of milling teeth into the depth a_P are the same, so the cutting force required, the workpiece is easy to produce vibration.
