加工油缸缸筒,通常采用的工艺方法是在专用机床上,用粗镗头装上粗镗刀对缸筒进行去除大部分余量的粗加工,再进行精镗滚压或珩磨。由于缸筒粗加工余量大,通常最大切削深度ap为4～6mm;而缸筒壁厚差和内孔偏心的影响还会造成余量不均匀,造成局部余量更大,这就要求刀具切削深度要大 Processing cylinder cylinder, the process is usually used in special machine tools, with a rough boring head mounted on the rough boring cylinder to remove most of the remaining rough machining, and then fine boring rolling or honing. As the roughing allowance for the cylinder is large, usually the maximum cutting depth ap is 4 ~ 6mm; and the difference of the cylinder wall thickness and the eccentricity of the bore also causes the unevenness of the allowance, resulting in a larger local allowance, which requires that the tool Cutting depth to big
