在杨浦区科协支持下,自贡硬质合金厂前不久在我厂试验了“767”新牌号硬质合金刀片,取得了优异的效果。根据几种刀片对比试验情况比较,这种刀片在提高了切削用量条件下,刀具耐用度比YG6提高4～5倍,比YG6涂层提高2～3倍,同时加工零件质量提高,有效地克服了我厂铸件因不回火而表面硬度较高,加工困难等技术问
In Yangpu District CAST support, Zigong Cemented Carbide plant recently in our factory tested the “767” brand new cemented carbide inserts, and achieved excellent results. According to the comparison of several kinds of blades, the blade’s cutting durability is improved by 4 ~ 5 times than that of YG6 and 2 ~ 3 times higher than that of YG6 under the condition of increasing the amount of cutting, meanwhile, the quality of processed parts is improved and overcome effectively My factory castings because of the high hardness of the surface hardness, processing difficulties and other technical questions
