How to define the order and logical relationship of the use of master and working gauges in thread detection?
Publish Time: 2025-04-09
Master, commonly known as "standard gauge" or "calibration gauge", is a reference tool in thread detection. It is manufactured according to international or industry standards and has extremely high accuracy and stability. The main function of the master is to calibrate other detection tools, such as working gauges, and as the final basis for thread detection. In the process of thread detection, the use of master is a key link to ensure the consistency of the test results with the standard.Working gauges are tools frequently used in actual detection. It is calibrated according to the master and used for daily detection work. Although the accuracy and stability of working gauges are slightly lower than that of the master, they are sufficient to meet the needs of most thread detection. The frequency of use of working gauges is high, so the risk of wear and damage is relatively high. In order to ensure the accuracy of the test results, working gauges need to be calibrated regularly with the master.In thread detection, the order and logical relationship of the use of master and working gauges can be summarized as "master first, then working gauge, master to calibrate working gauge". Specifically, the master is used to perform preliminary detection of the thread to determine whether it meets the standard. Then, the working gauges calibrated by the master are used for daily detection. During the use of working gauges, if the test results are inconsistent with the master, or the working gauges are worn or damaged, the master needs to be used again to calibrate the working gauges.This order of use and logical relationship reflects the different roles and values of master and working gauges in thread detection. As a benchmark tool, the master ensures the accuracy and reliability of the test results; while working gauges, as actual detection tools, improve the detection efficiency and convenience. The two complement each other and together constitute a complete system of thread detection.In actual operation, in order to ensure that the order and logical relationship of the use of master and working gauges are correctly implemented, the following points should also be noted: First, it is necessary to strictly follow the standard operating procedures to ensure the standardization and consistency of the detection process; second, it is necessary to regularly maintain and maintain the master and working gauges to ensure their accuracy and stability; third, it is necessary to establish a complete calibration and traceability system to ensure the traceability and credibility of the test results.In summary, the order and logical relationship of the use of master and working gauges in thread detection are the key to ensuring the accuracy and reliability of the test results. By clarifying their functions and values, and paying attention to relevant matters in actual operations, the efficiency and quality of thread detection can be effectively improved.
