在有多轴自动机(沈阳第三机床厂产品) 的工厂里,需要一种正弦曲线的鼓形凸轮,如 图1所示。 加工这种凸轮,一般需要专门的凸轮铣 床,同时还需各种形状的靠模板。我厂自从开 展技术革命以来,在没有凸轮铣床的条件下, 我们依靠“三结合”设计出一种在普通铣床上用 分度头加工正弦? In a factory with a multi-axis automaton (a product of Shenyang No.3 Machine Tool Plant), a sinusoidal drum cam is needed, as shown in Figure 1. Processing of such cams, generally require a special cam milling machine, but also need a variety of shapes by the template. Since our company started the technological revolution, in the absence of cam milling machine, we rely on the “three combinations” to design a common milling machine with a sub-head machining sine?
