After using the American trapezoidal thread ring gauge, the attachments on the measuring part should be cleaned up in a timely manner and stored in the designated measuring tool box. The measuring tools on the production site should be placed in the designated position of the process, handled gently to prevent damage to the measuring surface due to collision. It is strictly prohibited to forcefully screw measuring tools into threads as cutting tools to avoid early wear. When using a gauge, it should be noted that the tolerance level and deviation code of the thread being tested are the same as those marked on the ring gauge (such as M24 × 1.5-6h and M24 × 1.5-5g, which have the same shape but different thread tolerance zones). Misuse will result in a batch of non-conforming products. Inspection and measurement process: First, clean the oil and impurities on the thread being tested. Then, after aligning the ring gauge with the thread being tested, rotate the ring gauge with the thumb and index finger to make it pass through the entire length of the thread in a free state, otherwise it will be judged as qualified. When using a stop gauge, it should be noted that the tolerance level and deviation code of the thread being tested are the same as those marked on the ring gauge. Inspection and measurement process: First, clean up the oil and impurities on the thread being measured. Then, after aligning the ring gauge with the thread being measured, use the big female finger and index finger to rotate the ring gauge. If the length of the threaded thread is within 2 pitches, it is considered qualified. Otherwise, it is judged as unqualified. After the maintenance and upkeep of the threaded ring gauge, any attachments to the measuring area should be promptly cleaned and stored in the designated measuring tool box. The measuring tools on the production site should be placed in the designated position of the process, handled gently to prevent damage to the measuring surface due to collision. It is strictly prohibited to forcefully screw measuring tools into threads as cutting tools to avoid early wear. Adjustable thread ring gauge is strictly prohibited from being adjusted by non measuring personnel to ensure the accuracy of the measuring tool. Welcome to our company for inspection and consultation.
