我厂加工8117~#硬质合金阀件时,先后试用了不同牌号的硬质合金刀片,如 YG05、YT 类合金等,在3.4m 立车上,虽经多种不同速度的试验,但始终达不到切削目的,后来改用了 YG10刀具,情况明显改善,经试车,车速为2.5～5r/min,进刀量约为0.2mm 左右,取得成功,不过,车刀在砂轮机上磨好后,必须在金钢石小油石上刃磨光洁,否则耐用度和加工件的光洁度将 When we processed 8117~# hard alloy valve parts, we tried different grades of cemented carbide inserts, such as YG05 and YT alloys. In the 3.4m vertical lathe, despite many different speed tests, we always tried Can not reach the purpose of cutting, later changed to the YG10 tool, the situation improved significantly, after the test, the speed is 2.5 ~ 5r/min, the feed amount is about 0.2mm or so, achieved success, but after turning the wheel on the grinding machine , must be sharpened on the diamond stone, otherwise the durability and finish of the workpiece will be
