对轧辊轴颈上的四个梅花键槽(参见图1)的加工,以往是在单轴卧式镗床或经改装的专用单杆镗铣床上采用分度的方法逐槽进行加工的。这种加工方法,由于零件非常笨重,生产效率低、劳动强度很大。因此我们联合研制了通用可调四轴梅花铣床,一次装夹、四轴同步一次走刀就能把四个梅花键 The machining of four spline grooves on the roll journals (see Figure 1) has historically been slot-by-slot on a single-axis horizontal boring machine or a modified single-bar boring mill. This processing method, due to the very heavy parts, low productivity, labor-intensive. Therefore, we jointly developed a universal adjustable four-axis plum milling machine, a clamping, four-axis synchronous one pass will be able to put four plum keys
