How to zero a micrometer
Micrometer is a high-precision measuring tool widely used in mechanical processing, precision manufacturing and other fields. Proper zeroing is a critical step in ensuring measurement accuracy. This article will introduce the zero adjustment method of the micrometer in detail, and provide you with a practical guide based on the hot topics and hot content on the Internet in the past 10 days.
1. Basic steps for micrometer zero adjustment
1.Clean measuring surface: Use a clean soft cloth or paper towel to wipe the measuring surface of the micrometer to ensure there is no dust or oil.
2.closed measuring surface: Gently rotate the micrometer's micrometer cylinder to completely close the measuring surface.
3.Check zero point alignment: Observe whether the scale lines of the fixed sleeve and the micron cylinder are aligned. If misaligned, a zero adjustment is required.
4.Adjust zero point: Use a special tool (such as a zeroing wrench) to rotate the micrometer cylinder until the scale lines are completely aligned.
5.Verify zeroing: Repeatedly close the measuring surface to ensure stable zero point alignment.
