Production process of high-toughness ceramic cutting tool
The invention discloses a production process of a high-toughness ceramic cutter. By adding nano silicon carbide, nano titanium nitride, modified sepiolite powder, zirconium oxide whiskers and aluminum hydroxide coated calcium fluoride, the toughness, thermal shock resistance and bending strength of the produced ceramic cutting tool are effectively improved. According to GB/T4741-1999 measurement, the bending strength of the high-toughness ceramic cutting tool is 1000 to 1500 MPa. Meanwhile, the invention discloses machining equipment, and the machining equipment can polish one face of the ceramic cutter and clean the other face of the ceramic cutter at the same time. Water is sprayed on the surface of the abrasive belt while the grinding surface is ground, so that chippings can be prevented from splashing while overheating during grinding is prevented; whereas the cleaning of the other side is that sewage generated in the polishing process is recycled and sprayed on the surface of the ceramic cutting tool through filtration and atomization.
本发明公开一种高韧性陶瓷刀具的生产工艺，本发明通过纳米碳化硅、纳米氮化钛、改性海泡石粉、氧化锆晶须、氢氧化铝包覆氟化钙的添加，有效增加了生产得到的陶瓷刀具的韧性、抗热震性能以及抗弯强度，根据GB/T4741‑1999测定，该高韧性陶瓷刀具的抗弯强度为1000‑1500MPa，同时本发明公开一种加工设备，该加工设备可以对陶瓷刀具在一面打磨的同时，对另一面进行清洗处理，对打磨面打磨的同时也将水喷洒在砂带表面，在防止打磨时过热的同时可以防止碎屑的飞溅，对另一面的清洗是将打磨过程中产生的污水进行回收处理，并通过过滤雾化喷洒在陶瓷刀具表面。
