螺旋式鼓风机是一种新型的鼓风机,是船用柴油机十分重要的配套机器,螺旋式鼓风机的关键零件——左右转子(图1),我们是在普通铣床或滚齿机上加工的。由于“转子”的螺旋型面形状复杂,加工精度要求高,且“转了”的密封带部分是一种特殊的曲线,因此,刀具的尺寸计算非常复杂。在加工过程中,有很多因素对螺旋槽法向形状产生影响,如盘形铣刀直径的大 Spiral blower is a new type of blower, marine diesel engine is a very important supporting machine, spiral blower key components - left and right rotor (Figure 1), we are in the ordinary milling machine or hobbing machine processing. Due to the complex shape of the “helix” helical profile, high machining accuracy and the fact that the “turned” part of the seal tape is a special curve, the tool size calculation is very complicated. In the process, there are many factors that affect the normal shape of the spiral groove, such as disc cutter diameter
