我厂加工湿式铸铁气缸套内孔 ,工艺安排粗铰孔在 DU4 0 6四轴镗机床上加工。缸套的定位原来是靠定位圈和定位齿圈。在加工过程中 ,经常出现缸套转动 ,缸套转动就容易使定位齿圈的局部齿划伤 ,就无法定位了 ,必须换用新的齿圈。由于齿圈的加工费高、制造周期长 ,满足不了生产需 I plant processing wet cast iron cylinder liner hole, the process of arranging rough reaming in DU4 0 6 four-axis boring machine processing. Cylinder liner positioning is the original positioning ring and positioning ring gear. In the process of processing, cylinder liner rotation often occurs, the cylinder liner is easy to make local tooth positioning gear tooth scratches, you can not locate, you must use a new gear ring. As the ring gear processing fees, long manufacturing cycle, can not meet the production needs
