5.The developing situation, function features, use range, manufacture technology, design principles, cutting parameters and invalidation mechanism of polycrystalline diamond (PCD) cutting tools are summarized.
6.As one of the four largest cemented carbide cutting tools manufacturers in the world, SECO Tools AB has a full range of products for milling (including solid carbide tools), turning, threading, drilling, reaming, PCBN inserts, boring and tooling system.
8.The ratio of the volume worn away from PDC cutters to frictional works consumed during cutting rock was used as the rock abrasiveness index. The ratio values were in range 10 -6 mm 3/(kN·m) to 10 -3 mm 3/(kN·m).
9.The laser cutting NC system developed by using Visual C++ 6.0 based on these above-mentioned researches and related technologies met the demand of range of the speed and could move smoothly.
基于以上研究和相关技术，利用Visual C++ 6.0编程工具所开发的激光切割数控系统不但进给速度变化范围达到使用要求，而且运动平稳。收藏指正
10.Our product range covers drilling and demolition, direct fastening, diamond and anchoring systems, firestop and foam systems, installation, measuring and screw fastening systems as well as cutting and sanding systems.
