过去,我厂在加工某些批量较少或不宜冲制的薄圆零件时,多以钳工锅坯,车工车制的方法加工,不仅工序长,劳动强度大,而且费材料,质最也不好。后来,我们设计制作了一种结构简单,使用方便的薄板割圆工具(如图1所示)。利用它,可在一般立钻或工具铣床上直接切割出合乎要求的薄圆零件。经多年使用,效果甚好。图2所示零件是“某某——3”上的有机玻璃护盖,原需钳工锯坯,车工车圆 In the past, I plant in the processing of some batches less or should not be punched thin circular parts, and more fitter pan, lathe system processing methods, not only the length of the process, labor-intensive, and the cost of materials, the most quality is not it is good. Later, we designed a simple and easy-to-use sheet metal rounding tool (Figure 1). Use it to directly cut the thin round parts required by the general drilling or milling machine. After years of use, the effect is very good. The part shown in Fig. 2 is the plexiglass cover on “XX - 3”. The fitter saw billet,
