我厂没有加工球面蜗杆的专用机床,因此,加工球面蜗杆曾一度发生困难。后来我们在普通滚齿机上采用两个刀头刀盘来加工,但效率很低。根据球面蜗杆铣床的加工原理及刀具结构,又分析了其主要矛盾是在刀具上,因此,我们进行改进。我们遵照伟大领袖毛主席关于“独立自主、自力更生”的教导,发挥了冲天的革命干劲,在短时间内设计制造了球面蜗杆插齿刀,如图1所示。
I plant not processing spherical worm dedicated machine, therefore, the processing of spherical worm was once difficult. Later, we used two cutter heads on ordinary hobbing machine to process, but the efficiency was very low. According to the machining principle of spherical worm milling machine and the structure of the cutter, it analyzes the main contradiction is on the cutter, therefore, we make improvements. In accordance with the teachings of Chairman Mao on “independence and self-reliance,” as the great leader, we have played a radical revolutionary drive and designed and manufactured a spherical worm gear cutter in a short period of time, as shown in Figure 1.
