在龙门刨床上加工曲面是机械加工中一个难题。我厂龙门刨床上经常有曲面零件加工,以往加工曲面一直是用手赶刀,或用近似样板刀靠出。这次要加工的如图1所示大型椭圆冲模,因为椭圆弧太大,精度难以达到设计要求,而且时间紧,用老办法太慢,所以我厂研制了龙门刨刨椭圆靠模工具,经使用效果很好,从此解决了龙门刨加工 Machining surfaces on a planer is a challenge in machining. The gantry planer in our factory often has the processing of the surface parts. In the past, the machining surface has always been used to drive the knife, or the approximate model knife can come out. This time to be processed as shown in Figure 1, a large oval die, because the oval arc is too large, the accuracy is difficult to meet the design requirements, and the time is tight, the old method is too slow, so I developed a gantry planer oval by the tool, The use of good results, from solving the planer processing
