A series of standard taps and modified-tooth taps with a cutting cone angle of 7°30~′ were prepared from high-speed steel W9 and used to tap nickel-based high-temperature alloy GH4169.
用高速钢W9制备了切削锥角为7°30′的M6修正齿丝锥和标准丝锥,并用其对Ni基高温合金GH4169进行攻丝试验;采用扫描电子显微镜和显微硬度计测定了攻丝后丝锥顶后刀面的表面形貌及试件底孔截面各层硬度。
It was showed by some tapping tests that modified-tooth taps were the more efficient tools in tapping small hole of high-temperature alloy GH4169,compared with the standard taps.
以修正齿丝锥的攻丝成形原理为理论基础,利用I-DEAS软件为开发平台,建立了修正齿丝锥的结构模型并模拟了攻丝过程,解决了修正齿丝锥设计的盲目性。
