一九八一年以来,我国开始试贯齿轮新标准。等效采用国际齿轮标准的我国齿轮新标准,对齿轮刀具提出了更高的精度要求。此外,齿轮滚刀的国际标准也于八二年颁布。一些先进国家的滚刀,插齿刀标准也先后修订,规格范围扩大,精度指标也相应提高。为了适应贯彻齿轮新标准的需要,同时也为国产齿轮刀具进入国际市场创造条件,工具研究所组织有关工具厂先后修订了齿轮滚刀和插齿刀标准,并制订了高精度齿轮滚刀和剃前齿轮滚刀标准。
Since 1981, our country has started to test new standards of gears. Equivalent to the new gear standard in China’s gear standards, gear cutting tools put forward higher accuracy requirements. In addition, gear hobs of the international standards were enacted in 1982. Some advanced countries hob, gear shaper standards have also been revised, the scope of specifications to expand, the accuracy index also increased accordingly. In order to meet the needs of the new gear standards, but also to create conditions for domestic gear cutting tools to enter the international market, the Tool Institute has organized the relevant tools factory has revised gear hob and gear shaper standards, and developed a high-precision gear hob and shaving Front gear hob standard.
