Problems solved by technology

[0005] In addition, the traditional method of using external nozzles to provide cutting fluid generally requires a separate liquid spray device next to the milling head, which has poor installation and use flexibility; Surface loss, when the processing depth of cut is large, it is difficult for the cutting fluid to fill the entire processing gap in time due to the large flow resistance in the processing gap, resulting in insufficient liquid supply in the processing area, which limits the increase in material removal rate
Therefore, the internal injection liquid supply method is introduced, and the cutting fluid is directly sprayed into the machining gap through the inner hole of the milling head, forming a stable and uniform flow field in the machining gap, which can timely take away the Joule heat and insoluble Products, etc., significantly increase the milling depth and increase the processing area, which is more conducive to the removal of large margins of difficult-t

Description

technical field [0001] The invention relates to the technical field of electrolytic spark milling, in particular to a multifunctional milling head installation device for electrolytic spark milling. Background technique [0002] At present, for the integral components of difficult-to-cut materials such as titanium alloys and high-temperature alloys, the commonly used manufacturing processes include CNC milling, EDM, and electrolytic machining. When EDM is used, not only the processing efficiency is still limited, but also the recast layer, heat-affected zone and micro-cracks are easily formed on the workpiece processing surface, which will affect the fatigue strength and working life of the overall component. Although electrolytic machining has the advantages of no tool cathode loss, high machining efficiency, and stress-free machining, a passivation film with high resistance and dense structure is easy to form on the surface of the workpiece during the anodic dissolution pr...
