When handling the quality inspection report of the watch file, it is necessary to follow QB T 25695. Detection methods. This standard specifies the testing methods for watch files to ensure that the quality of watch files meets the relevant requirements. This article will introduce QB T 2569 in detail5. The operation steps and precautions of the detection method help you better understand the quality inspection process of watch files.
1. Preparation before testing.
Before you start your inspection, you'll need to prepare the tools and materials you need, including clock files, measuring tools, records**, and more. At the same time, familiarity with QB T 2569 is required5. The relevant requirements and operation steps of the detection method to ensure the accuracy and reliability of the detection process.
Second, the detection steps.
1.Visual inspection.
First of all, the appearance of the watch file is inspected to see if its surface is smooth, punctured, and has no obvious scratches or bruises. At the same time, it is necessary to check whether the size of the watch file meets the requirements and whether the proportions of each part are coordinated.
2.Hardness testing.
Hardness is one of the important indicators to measure the quality of watch files. According to QB T 25695. The provisions of the detection method can be measured by Rockwell hardness tester or Shore hardness tester. When measuring, it is necessary to select the appropriate measurement point and ensure the accuracy and reliability of the measurement results.
3.Metallographic structure testing.
Metallographic structure is one of the important factors affecting the quality of watch files. According to QB T 25695. According to the provisions of the detection method, an optical microscope or a scanning electron microscope can be used for observation. When observing, it is necessary to select representative areas and rate the metallographic structure.
4.Abrasion resistance test.
Abrasion resistance is one of the important indicators to measure the service life of a watch file. According to QB T 25695. The provisions of the testing method can be tested by using a wear testing machine. During the test, it is necessary to select the appropriate friction pair and test conditions, and ensure the accuracy and reliability of the test results.
3. Precautions.
During the inspection process, it is necessary to keep the measuring tool clean and in good condition to avoid affecting the measurement results.
When handling the quality inspection report of watch files, it is necessary to strictly abide by the relevant standards and regulations to ensure the accuracy and reliability of the test results.
When using a watch file, you need to follow the instructions for use to avoid damage to the file. At the same time, it is necessary to regularly inspect and maintain the watch file to ensure its service life and stable performance.
