过去,加工圆管的倒角,我厂都是以手工进行,不仅工效低、质量差,而且劳动强度也较高。针对以上情况,后来革新成功机械化倒角工具(图1)。使用这种工具既减轻了劳动强度,又提高了质量,并且,工效比手工操作可提高15～20倍。管子倒角排是锪钻中的一种,它的用途是在管子的内外径同时进行倒 In the past, the processing of circular pipe chamfering, I plant are by hand, not only low efficiency, poor quality, but also higher labor intensity. In response to the above situation, the mechanized chamfering tool was successfully revamped (Figure 1). Use of this tool not only reduces the labor intensity, but also improves the quality, and the work efficiency can be increased by 15 ~ 20 times than the manual operation. Pipe chamfering row is a drill in the drill, its use is in the pipe inside and outside diameter at the same time down
