| 聚晶金刚石(PCD)刀具具有持久的耐用度、稳定的加工精度、良好的工件表面粗糙度等优良特性。用于有色金属和部分非金属材料的半精加工和精加工。 工件表面粗糙度:Ra 1.6——0.16 刀具寿命:为硬质合金的几十倍—上百倍 PCD cutting tools have good properties such as longer tool life、stable machining precision、good surface roughness,etc can be used for precision or semi-precision machining of non-ferrous and non-metallic materials. Surface roughness of machined material:Ra 1.6－0.16 Life of tools:several tens to hundred times of tungsten carbide. | |
| 聚晶立方氮化硼(PCBN)刀具具有硬度高、红硬性(>1300°C)好等特点。用于高硬度黑色金属和铸铁等材料的精加工。在金属加工中的许多场合可以车、镋、铣代替磨削工艺。由于在切削过程中刀具对工件有挤压作用，这不但可提高工件表面光洁度，还可使工件表面产生加工硬化，提高工件的机械性能。 工件表面粗糙度： Ra 0.3—1.6 刀具寿命: 为硬质合金的几十倍以上 PCBN cutting tools have high hardness,good high temperature hardness (>1300(C).Used for high precision machining of high hardness materials such as ferrous metals and cast Iron. In some Circumstances,turning,boring,milling are often used to instead cutting process .The surface roughness is improved by extrusion during cutting,and this process can also result in harder on surface and increase the mechanical properties of lorkpiece machined. Surface roughness of machined material:Ra 0.3—1.6 Life of tools: tens of times of tungsten carbide | |
| 金刚石膜 (CVD) 刀具兼备聚晶金刚石和单晶金刚石刀具的优良特性,并在一定程度上克服了他们各自的不足。大量实践证明,金刚石膜 (CVD) 刀具使用寿命和加工光洁度均优于聚晶金刚石刀具,与单晶金刚石接近,而价格却远远低于价格昂贵的单晶金刚石刀具。是制造超硬材料刀具的理想材料。 CVD diamond cutting tools combine the good properties of PCD cutting tools and PCBN cutting tools, at the same time compensate some ings of them in some degree.It has been proved that life and surface roughness of CVD diamond cutting tools are better than those of PCD cutting tools,and similar to single crystal diamong .But the price is much lower than that of single crystal diamond. CVD diamond is an ideal choice for cutting tools. | |
