Repair and maintenance of precision measuring tools

During the use of the measuring tool, do not stack it with tools, tools such as boring tools, boring heads, turning tools and drill bits to avoid bumps.

1. When measuring parts on the machine tool, wait until the parts are completely stopped. Otherwise, the measuring surface of the measuring tool will wear out prematurely and lose precision, which will cause an accident.

2. Before the measurement, the measuring surface of the measuring tool and the measured surface of the part should be cleaned to avoid the measurement accuracy due to the presence of dirt. The use of precision measuring tools such as vernier calipers, centimeters and dial gauges to measure forging blanks, or surfaces with abrasives (such as silicon carbide, etc.) is wrong, which tends to cause the measuring surface to wear quickly and lose precision.

3. During the use of the gage, do not stack with tools and tools such as trowels, hoes, turning tools and drill bits to avoid bumps. Also, don't just put it on the machine to avoid damage to the gauge due to machine vibration. In particular, vernier calipers, etc., should be placed flat in a special box to avoid deformation of the ruler.

4. Measuring tools are measuring tools and must not be used as substitutes for other tools. For example, taking a vernier caliper line, taking a square ruler as a small hammer, taking a steel ruler as a screwdriver screw, and cleaning the chip with a steel ruler are all wrong. It is also wrong to use the gage as a toy, such as holding the percentile in the hand and waving or shaking it. It is easy to make the gage lose accuracy.

Proper use of precision measuring tools is one of the important conditions for ensuring product quality. In order to maintain the accuracy of the gage and the reliability of its work, in addition to the proper use of the gage in operation, the gage must be maintained and maintained.
