How to read a manual micrometer

Step 1: Take the Measurement Place your part between the measuring faces. Bring the measuring face towards the part by rotating the spindle. When you are close use rachet to press the measuring face against the part. You should achieve sufficient measuring Now you can lock the dimension using the Estimated Reading Time: 2 mins. To Read a Micrometer z First, read the Barrel Number z Second, read the Sleeve Graduations z Finally, read the T himble Number z Add these three readings together to obtain the correct reading z To best way to practice using a micrometer is . Here we are going to learn to read the micrometer by figuring out the markings on the Thimble and the Sleeve. The Sleeve does not move. It looks like a ruler with ten numbers. The space between each number is divided into quarters. As the Thimble rotates around this Sleeve it covers up, or reveals the numbers marked on the Sleeve.

In a micrometer, the object you wish to measure is clamped between the anvil (the stationary end of the clamp) and the spindle (the moving part of the clamp). Once the object is secured in the clamp, you use the numbering system on the thimble (the handle portion) to find your measurement. Inside Micrometer: While the outside micrometer is used. Micrometer: To read either a" or" micrometer, you place the material to be measured between the anvil and spindle, and then turn the ratchet until the spindle closes down and stops moving. Then you read the markings on the sleeve and thimble. In the case of a" micrometer you would. the "Reading the Scale" procedure above. OPERATION TROUBLESHOOTING MICROMETER SCREW WEAR ADJUSTMENT Wear on the micrometer screw in the sleeve will affect accuracy of the measurement. Please adjust using the key provide as required. ①Remove the thimble by rotating as shown. ②Insert the key into the notches in the exposed brass nut.

Step 1, Familiarize yourself with the anatomy of a micrometer. Some parts are stationary while others are movable. Ratchet stop Thimble Frame Thimble lock Spindle Anvil SleeveStep 2, Clean the anvil and spindle before beginning. Use either a clean sheet of paper or soft cloth, and hold it between the anvil and the spindle. Gently twist and close on the sheet or cloth. Slowly, pull out the sheet or the cloth.[1] X Research source This practice isn't a necessary step for measuring, but keeping. Note the measurements on a test sheet that gives length, tolerance, measured length, and error. You should also check the flatness and parallelism of the anvils. Use a small sphere, or the stylus of a digital probe. Set zero with the sphere in the center of the anvil faces and zero. Parts of a micrometer. Read the sleeve: In Figure 2 above, when tightening down the thimble on our material, it stopped at a point to the right of "2" on the sleeve,this indicates". We There is one line visible between the graduation numbered"2" on the sleeve and the edge of the thimble.
