Requirement of precision machining on electrode
It is necessary to use precise manufacturing method to guarantee the quality of the electrode for precision machining.Electrode manufacturing should satisfy the demands of high accuracy, the general precision of the electrodes made by the high speed machining center to finish, after the completion of the processing should reach as far as possible need not artificial demand for electrode processing, finishing and polishing cases, this is done to avoid the electrode process after processing affected the precision of the electrode, but also in fabrication of electrode process level put forward higher requirements.
Electrode material is a key problem in precision machining.Red copper is the most widely used electrode material in the field of electrical processing, which can meet the requirements of high-precision processing. However, in the micro-machining, in order to reduce the loss of electrodes, reduce the number of electrodes, improve the quality of machined surface, and achieve high and stable machining, more expensive copper and tungsten alloy electrode materials should be considered.
The electrode shall be used for the detailed projection measurement of the size and shape before the edm, and the electrode shall be used for machining after the overall inspection is qualified.
In actual production, there are many scrap cases caused by unqualified electrodes.Therefore, it is very important to grasp the manufacturing of electrodes in precision machining.
