Method for prolonging cutting life of polycrystalline cubic boron nitride cutter
The invention relates to a surface treatment method for a metal cutting polycrystalline cubic boron nitride cutter, in particular to a surface treatment method capable of prolonging the service life of the metal cutting polycrystalline cubic boron nitride cutter, which comprises the following process steps: selecting a cutter, and carrying out ultrasonic cleaning for 30 minutes by using an acetone solution to remove impurities such as oil stains on the surface; the treated cutter is put into a program cryogenic box, the cooling rate is strictly controlled to be 5 DEG C/min, the temperature is slowly reduced to-150 DEG C to-190 DEG C, the heat preservation time is 3-18 h, then the temperature is slowly increased to the room temperature (the heating rate is 2 DEG C/min), after treatment is completed, the cutter is put into a resistance furnace to be subjected to tempering treatment at 150 DEG C to 200 DEG C (the heating rate is 2 DEG C/min), heat preservation is conducted for 1-3 h, and then the cutter is cooled to the room temperature along with the furnace; and after the treatment is finished, taking out the cutter, and carrying out ultrasonic cleaning with an acetone solution for 5 minutes. The cryogenic treatment process is used for performing surface treatment on the polycrystalline cubic boron nitride cutter, the cost is low, large-scale industrial application is easy to realize, the internal structure of the cutter can be improved, the surface performance is improved, and the service life is prolonged.
本发明涉及一种金属切削聚晶立方氮化硼刀具表面处理方法，具体是一种能够提高金属切削聚晶立方氮化硼刀具使用寿命的表面处理方法，包括下述工艺步骤：选择刀具，并采用丙酮溶液进行超声波清洗30min去除表面的油污等杂物；处理后的刀具放入程序深冷箱中，严格控制降温速率5℃/min，先缓慢降低温度到‑150℃~‑190℃，保温时间3‑18h，之后缓慢升温到室温（升温速率2℃/min），处理完毕后再将刀具放入电阻炉中进行150℃‑200℃的回火处理（升温速率2℃/min），保温1‑3h后随炉冷却到室温；处理完毕后取出刀具，进行丙酮溶液的超声波清洗5min。本发明使用深冷处理工艺对聚晶立方氮化硼刀具进行表面处理，发明成本低，易于实现大规模工业化应用，可以改善刀具内部的组织，提升表面性能，提高使用寿命。
