某工程机械上的锥形长螺旋叶片轴属于典型细长轴结构,加工过程由于刚性较差,且不能采用中心架、跟刀架等辅助支撑工具,在断续切削方式下容易产生振动及变形,难以保证叶片外圆加工质量。针对上述情况,提出一种加工该类型锥形长螺旋叶片外圆的车削工艺方法,并选用合理的刀具,取得良好的效果。
Conical long helical blade shaft on a construction machine belongs to the typical slender shaft structure. Due to poor rigidity during machining, auxiliary support tools such as a center frame, a turret and the like can not be used, and vibration and deformation easily occur in the intermittent cutting mode , It is difficult to ensure the processing quality of the blade outer circle. In view of the above situation, a turning process method for machining the outer circle of the long conical helical blade of this type is proposed, and a reasonable tool is selected to obtain a good effect.
