图1所示槽形,是一种工件上的特殊封闭槽形。由于槽形复杂,因而加工比较困难。为了满足加工要求,我们利用X 62铣床的支架改装了一个转角铣头(图2为示意图)。采用这种铣头加工之后,既提高了加工质量,又提高了效率。转角铣头结构比较简单,使用起来也较为方便。具体操作方法为:铣削时,心轴7靠拨杆9 The groove shown in Figure 1 is a special closed groove on a workpiece. Due to the complex trough, it is difficult to process. In order to meet the machining requirements, we converted a corner milling head using a bracket for the X 62 milling machine (Fig. 2 shows the schematic). After using this milling head processing, not only improve the processing quality, but also improve efficiency. Corner milling head structure is relatively simple, it is also more convenient to use. The specific method of operation: milling, spindle 7 by the lever 9
