我廠去年大批生產的某產品,每台上有十根大小不同的花键軸。这些花键軸的公差要求相当高,而且加工數量很多,用高速鋼成形銑刀來加工,不但效率低而且表面光潔度不高。經过工人和技術人員的共同研究,改進用硬質合金成形銑刀來高速銑削花键軸,使生產效率提高三倍多。現在把这個經驗介紹如下: Last year, I plant a large number of production of a product, each with ten different spline shaft. Tolerances of these spline shafts are quite high and the number of machining is high, with high-speed steel forming milling cutter to process, not only inefficient but also the surface finish is not high. After the joint research of workers and technicians to improve the use of carbide milling cutter to mill spline shaft speed, the production efficiency more than tripled. Now introduce this experience as follows:
