Problems solved by technology

However, the above-mentioned processing and quality control methods have the following problems: First, the time interval between detecting the out-of-tolerance of the microhole flow rate and feeding back to the EDM operator to adjust the parameters of the microhole machining is relatively long, and within this interval time, Some parts with unqualified flow have been processed, which has reduced the pass rate; second, the micropore flow detection cannot fully cover, and it is difficult to guarantee the quality; third, after sampling unqualified parts, it is necessary to trace the quality of the parts before the sampling , reducing production efficiency

According to the micropore machining device and method, the production efficiency is improved, the product quality is guaranteed, and the product percent of pass is increased.

Description

technical field [0001] The invention relates to the technical field of micro-hole processing, in particular to a micro-hole processing device and a processing method. Background technique [0002] In the common rail system, the parts with micropores are usually the core components, and the micropore flow generally directly affects the performance. Therefore, the flow dispersion difference after the micropore processing must be controlled. At present, EDM is mainly used for micropore processing. After processing, manual sampling of micropore flow is generally used for quality control. However, the above-mentioned processing and quality control methods have the following problems: First, the interval from the detection of the micro-hole flow out of tolerance to the feedback to the EDM operator to adjust the parameters of the micro-hole processing is long, and during this interval, the Some parts with unqualified flow have continued to be processed, reducing the pass rate; sec...
