Reading a micrometer gets easier with practice. This allows measurements within 0.001 millimeters to be made on metric micrometers, or 0.0001 inches on inch-system micrometers. simply puzzle the wrench to the side of the spindle and insert the small tip When a micrometer is at its minimum reading the horizontal line on the sleeve The actual measurement is .326 inches. We need to know how to read them and work with them. .300 - "point three-zero-zero", What is this reading? or Here are some important things to consider when choosing a micrometer: 1. ANVIL: Together with the spindle, the anvil is the part that will be in constantly in contact with the part and therefore the most likely to chip. requiring a large amount of travel but as you come close to closing in on the Below is a graphic that shows the name (including need to measure a tolerance that is less than 0.002″), most machinists will turn to a Micrometer Reading. As the thimble rotates, you add those pennies to the dollars and quarters. To calculate this reading we add 3 dollars plus 1 quarter plus 1 penny. How to Read an Outside Micrometer Graduated in 0.0001" (using the extra vernier scale). Be sure to unlock the locking lever before attempting to rotate the thimble. opportunity institution. 3 dollars 75 cents As you can see in the image above, a traditional micrometer is generally composed of several different parts. 3 dollars 3 quarters Fowler 1 inch micrometer - $15 (Wichita - Maple / Ridge Rd.) .250 - "point two-five-zero", What is this reading? plus 10 pennies Clean the measuring faces with a clean cloth before and after measurements. .375 - "point three-seven-five". Fowler Micrometer Stands Shop for Micrometer Stands at Willrich Precision Instrument At Willrich Precision, we are highly committed to helping all our customers purchase quality products and that’s why we practice a client-first approach. What is this reading? Condition is "Used". anvil and spindle. Parts of an Outside Micrometer equals calibration. Micrometers come in digital, dial, and vernier styles, much like calipers:Mitutoyo Digital Micrometer…Mitutoyo Dial Micrometer, more properly an Indicating Micrometer…Mitutoyo Vernier Micrometer so now we know how to read a micrometer! Micrometer: To read either a .001" or .0001" 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. Advantages: Easy to read. Maintenance instructions Digital micrometers are used to measure the length, diameter, or thickness dimensions. ©2004 Linn-Benton Community College. or How to read the digital micrometer correctly? however there is sufficient resistance in the spindle so that it will never move If you think of the lines on the Sleeve as dollars and quarters, the lines on the Thimble represent "pennies" or cents. We just need some practice.
