我厂在检修英国MK—Ⅱ型采煤机时,为了提高内齿套的加工精度,在工具磨床上,大胆革新成功了一种简易磨插齿刀的专用工具。它不但可以保证内齿套的加工质量,也解决了制造插齿刀的技术关键。为今后刃磨不同规格的插齿刀闯出一条新路。80年7月份由大同市科委组织,在大同齿轮厂进行了技术表演,并受到兄弟单位的一致好评。现将该经验介绍如下: I plant in the maintenance of the British MK-Ⅱ type shearer, in order to improve the accuracy of the gear set, the tool grinder, a bold innovation succeeded in a simple grinding gear shaper tool. It can not only ensure the quality of the machining of the gear set, but also solve the technical key of manufacturing the gear setter. Sharpening a new path for Sharpening different specifications gear shaper in the future. July 80 organized by the Datong Municipal Science and Technology Commission, Datong Gear Factory conducted a technical performance, and by the brothers units alike. The experience is now introduced as follows:
