长期以来,电火花加工使用的工作液大多是煤油,但煤油易挥发、易着火、对人体有害、易碳化且使用寿命短。另一方面,研究表明,电火花加工过程中,工作液也参与物理化学过程,并起着很重要的作用。它不仅影响到加工效率和表面质量,而且还影响到加工稳定性和电极损耗,近几年来,许多国家都在大力进行这方面的研究。然而,由于电火花加工使用的工作液在加工性能,劳动保护,环境污染以及成本等方面要求甚多,目前开发的一些工作液还不能完全满足所有生产上的需求,因此人们期望有更加理想的工作液出现。美孚石油(亚太)有限公司,通过大量试验研究,不断改进,成功地开发了新一代电火花加工的工作液(称美孚第三代特效火花机油)。这种经过高度提炼精制而成清澈透明的工作液,具有优异的物理化学性能,高绝缘强度,低电导率,能使放电能量高度集中,有效地排屑并降低电极损耗,从而保证了高效率和高精度的加工要求。同时由于化学上的稳定性,它又
For a long time, the working fluid used in EDM mostly kerosene, but kerosene volatile, easy to fire, harmful to human body, easy to carbonization and short service life. On the other hand, research shows that EDM also participates in physicochemical processes and plays an important role in EDM. It not only affects the processing efficiency and surface quality, but also affect the processing stability and electrode loss, in recent years, many countries are vigorously carry out research in this area. However, since the working fluid used in EDM has many requirements in terms of processability, labor protection, environmental pollution and cost, some of the working fluids currently developed can not fully meet all production needs. Therefore, it is expected that there will be more ideal Working fluid appears. Mobil Oil (Asia Pacific) Co., Ltd., through a large number of experimental research, continuous improvement, successfully developed a new generation of EDM working fluid (called Mobil third-generation special effects spark oil). This highly refined refined and made of a clear and transparent solution with excellent physicochemical properties, high dielectric strength, low conductivity, can discharge energy is highly concentrated, effectively chip removal and reduce electrode wear, thus ensuring high efficiency And high-precision processing requirements. At the same time because of chemical stability, it again
