Quality Challenges:
In the early stage of equipment production, Womeng's quality inspection team found that the dimensional accuracy of some parts was unstable during the processing. Although the deviations were within the allowable range, there were still potential risks. Meanwhile, during a simulated operation test, the operating speed of the equipment did not meet the expected standards, and there were occasional short-term stuttering phenomena, which might affect the customer's production efficiency and the stability of product quality.
Root Cause Investigation and Process Optimization:
To address the issue of dimensional accuracy of parts, quality control engineers quickly organized an interdisciplinary team, including production process personnel, equipment maintenance personnel, and representatives of raw material suppliers, to conduct a comprehensive investigation of the entire production process. Through precision testing of processing equipment, rechecking the quality of raw materials, and meticulous analysis of production process parameters, it was discovered that the dimensional deviations were caused by the wear of cutting tools on a certain key processing equipment and the unreasonable setting of cutting parameters. The cutting tools were immediately replaced, and the cutting parameters were re-optimized according to the characteristics of raw materials and product requirements. At the same time, daily maintenance of the equipment and monitoring of the tool life were strengthened to ensure the stability of the processing accuracy of parts.
Enhanced Detection and Quality Traceability:
Throughout the improvement process, the inspection of the production process was further strengthened. The frequency of inspection by online inspection equipment was increased to monitor the product quality of each key process in real time. Meanwhile, the quality traceability system was improved, and detailed records were kept for information such as the production batch, processing personnel, and equipment parameters of each part, so that the root cause could be quickly traced and targeted measures could be taken when problems occurred. After the equipment was assembled, more stringent comprehensive performance tests for finished products were carried out, including continuous operation time tests and tests for switching between different product specifications, to ensure that the equipment could operate stably under various complex working conditions and meet the customer's production needs.
