Cutting Other Materials:The machining of plastics,fiber-reinforced plastics,graphite,asbestos,and other hard and abrasive constructional materials mainly requires abrasionresistance.Cutting pressures and power requirements are generally low.With thermoplasticsand some other materials,particular attention must be given to cooling because of softeningor degradation of the work material that might be caused by the heat generated incutting.An important application of cemented carbides is the drilling and routing ofprinted circuit boards.Solid tungsten carbide drills of extremely small sizes are used forthis work.
切割其他材料:加工塑料,纤维强化塑料、石墨、石棉、和其他硬质耐磨结构材料主要要求耐磨.切割压力和功率要求一般较低,对热塑性塑料和其他材料必须特别注意冷却,因为切割产生的热会造成加工材料的软化和劣化,硬质合金的一个重要应用是钻头和印刷电路板的线路,极小尺寸的固体碳化钨钻头用于此项工作.
