我们在X53T立铣床上加工了铁路机车结合子的圆弧齿轮(图1),解决了无专用设备加工圆弧齿轮的问题。具体方法如图2所示,圆转台2被固定在工作台上,分度头3和尾顶尖9的轴心也应对正,再把工件10用心轴固定在两顶尖之间。用百分表找正工件,使工件齿宽中线与圆转台中心重合,用 We are in the X53T vertical milling machine machined rail locomotive combination of arc gear (Figure 1), solves the problem of no special equipment processing arc gear. Specific method shown in Figure 2, the turntable 2 is fixed on the table, the indexing head 3 and the tail end of the axis 9 should also be positive, and then the workpiece 10 mandrel fixed between the two centers. Find the workpiece with a dial indicator, so that the center line of the tooth width of the workpiece coincides with the center of the rotary table
