摘要
综述流体动压槽加工工艺技术的研究进展,并评述各种加工技术在加工流体动压槽时存在的优缺点,包括光刻加工、电火花加工、电解加工、超声波加工、激光加工等;指出:光刻加工技术、电火花加工技术和激光加工技术加工流体动压槽是切实可行的,并已有成功案例,其中以激光加工技术应用得最为广泛,但其加工机制仍未得到深入研究;电解加工技术和超声波加工技术也具有加工流体动压槽的可行性;复合加工技术具有各种加工技术的优点,在流体动压槽加工方面具有更大的优势,是未来的一个发展方向;随着精密加工技术的不断发展,流体动压槽加工技术会朝着精确化、复杂化、高效化方向发展。
The study of the groove etched process for the hydrodynamic mechanical seals was reviewed, and the advanta- ges and disadvantages of various machining techniques in the process of groove were also reviewed, including photochemi- cal machining （ PCM ）, electrical discharge machining （ EDM ）, electrochemical machining （ ECM ）, uhrasonic machining （USM）, laser beam machining（ LBM）, and so on.It was pointed out that the techniques of P CM, EDM and LBM are feasi- ble and successful, among them,laser beam processing（LBM） is the most widely used, but its processing mechanism has not been in-depth studied.ECM technology and USM technology also has the feasibility of processing groove.Due to the ad- vantages of a variety of processing technology, composite processing technology has greater advantages in the groove etched process, and is a future direction of development.The groove etched process technology will be in the direction of precision, complexity and efficiency along with the continuous development of precision machining technology.
