在普通机床上对外径在8mm以下的细轴或内径在70mm以下的薄壁法兰盘的加工,因受三爪卡盘卡爪内圆弧R及卡爪外承厚度的局限,故装夹困难。 这时可采用如图1和图2所示的方法,将车床大三爪卡盘上,夹上一个 In the ordinary machine tool, the thin-walled flange with the outer diameter of less than 8mm or the thin-walled flange with the inner diameter of less than 70mm is difficult to clamp due to the limitation of the inner radius R of the three-jaw chuck claw and the outer thickness of the claw. At this time can be used as shown in Figure 1 and Figure 2 shows the method, the lathe big three jaw chuck, clip a
