可加工陶瓷材料具有可切削性,能进行车、铣、刨、磨、钻孔及攻丝等加工,这是与一般陶瓷材料相对而言。从切削可加工陶瓷材料时,刀具寿命短和欲达到工件质量要求的工艺较为困难来看,可加工陶瓷材料的可切削性是较差的。影响可加工陶瓷材料切削性能的主要因素是,材料的导热率低和材料容易产生脆裂性破坏等物理性能。由于可加工陶瓷材料的导热率很低,切屑又呈崩碎状态,因此在切削过程中产生的切削热高度集中在刀具的锋刃上,而使刀具迅速磨损。同时,在切削过程中产生大量粉末状切屑,对刀具的锋刃起到研磨的 Machinable ceramic materials with machinability, can be car, milling, planing, grinding, drilling and tapping processing, which is relative to the general ceramic materials. From cutting machinable ceramic materials, tool life is short and to meet the quality requirements of the workpiece more difficult process point of view, Machinable ceramic machinability is poor. The main factors that affect the machinability of machinable ceramic materials are the low thermal conductivity of the material and the physical properties such as brittle fracture of the material. Due to the very low thermal conductivity of the machinable ceramic material, the chips are again crumbled, so the cutting heat generated in the cutting process is highly concentrated on the cutting edge of the tool, causing rapid wear of the tool. At the same time, in the cutting process to produce a large number of powdered chips, the cutting edge of the tool played grinding
