Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parts processing, in particular to a combined parts processing structure. Background Art
[0002] In the prior art, for combined parts with large depth and small width, according to normal electrode design and processing, product area processing is time-consuming, and in order to control the bottom size of the part, multiple electrodes are required to process the bottom area of the part multiple times to achieve the control of the bottom shape size to meet the requirements of the drawing. In order to avoid the bottom size not meeting the requirements of the drawing due to electrode loss, multiple electrodes are used to process the bottom shape to clear the root, which easily causes the opening size of the part mouth area to exceed the tolerance due to multiple discharges. In order to avoid this problem, only small-power discharge processing can be selected, which will cause low efficiency and too long time.
