Tool gage maintenance and operation:
In the measurement of the machine parts, in order to obtain the desired accuracy, in addition to controlling the measurement environment, it is necessary to pay attention to the use and maintenance of the measuring tool itself. Due to improper use, measurement errors will occur; if the maintenance is not good, it will damage its accuracy and affect the quality of the product. Therefore, the use and maintenance of general measuring tools should pay attention to the following matters:
First, the preparation of the measuring tools before use:

Second, the use of measuring tools should pay attention to:
(1) The contact with the workpiece during the measurement should be appropriate and should not be skewed. Avoid touching the measuring surface with your hand and protect the measuring tool.
(2) The measuring force should be appropriate. Excessive measuring pressure will produce measurement error, which is easy to damage the workload.
(3) The clamping method of the workpiece should be appropriate to avoid inaccurate measurement.
(4) The workpiece in rotation cannot be measured to avoid danger.
(5) Do not force the measuring tool into the workpiece or use it on the vise.

(4) The performance of the storage gauge should be checked regularly and the maintenance record should be made.
(5) It should be inspected regularly and the size of the inspection should be qualified as the basis for continued use or elimination, and a record of comparison and maintenance should be made.
