How to solve the problem of low efficiency of EDM machine?


1) The initial discharge processing efficiency is low-----the electrode size scaling amount (spark position) is large, and automatic programming can select a condition chamber with a larger current. Pre-milling should be done as much as possible.


2) The EDM section in the middle of the program is inefficient—there is too much margin between the conditions of each section, and the machining allowance between the two sections can be appropriately reduced.


3) The last few stages of the program are low in efficiency. ---- Use the timing processing function to effectively control the finishing time (requires setting processing time).


4) The area input is too small ----- The system uses the area as the limit threshold. Even if the electrode size is larger, the large discharge condition will not occur due to the small area. In such cases, the input area value can be artificially increased.


5) The application type is not selected correctly—for example, the actual “large” cavity is selected and the “standard” application type is selected. "Microfabrication" is the least efficient of all application types.


6) Processing priority ----- Selecting low loss priority is inefficient, and selecting high efficiency priority is fast and the loss is too large.


7) Discharge, unreasonable combination of lifting knife ----- According to the processing state, adjust the height of the lifting knife and match the discharge time.


8) Optimize the parameters ---- reduce the pulse gap P and increase the servo reference COMP.


Improved process ---- use graphite electrodes to greatly improve overall production efficiency.
