Issues to pay attention to in mirror spark machine forming processing
1. Issues with improving processing accuracy: This mainly includes dimensional accuracy and contouring accuracy. There are many factors that affect contouring accuracy, the first being electrode wear. Therefore, for sharp corners, thin sheets, and the main cavity, it is necessary to decompose the processing. This part of the cavity, like a pattern mold, requires a significant increase in pulse width. Using large pulse width and small current processing primarily addresses the requirement for low wear. Secondly, it is important to prevent re-adhesion, especially with graphite. During high-energy processing, careful observation is needed to prevent damage to the geometric shape of the cavity. Additionally, attention should be paid to selecting an appropriate linear (oscillating) trajectory.

Two minutes to teach you to easily master the key points of mirror spark machining
People who do not understand high-precision mirror spark machines think that processing is very difficult to operate, and the ancients often said that "if you want to do a good job, you must first sharpen your tools." "Let's learn the following points that high-precision mirror spark machining must master, understand these processing points, and use high-precision mirror spark machining to process with Lei Xiaomei, you will definitely feel SO easy."
EDM principle
During EDM, one pole of the pulse power supply is connected to the tool electrode and the other pole to the workpiece electrode, both poles are immersed in a liquid medium with a certain degree of insulation (commonly paraffin or mineral oil or deionised water). The tool electrode is controlled by an automatic feed adjustment device to ensure that the tool and workpiece maintain a small discharge gap (0.01-0.05mm) during normal processing.
Mirror sparking machine forming process should pay attention to the problem
Today I will come together with you to understand the mirror spark machine forming processing should pay attention to several issues.
