Micrometer (device) - Wikipedia
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components [1] in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
The Ultimate Guide to Micrometers - Practical Machinist
2019年1月10日 · Micrometers, often called “mics”, are likely to be the most utilized precision measuring instrument in any machine shop. As they typically measure in .0001” increments (or .01mm for metric models), micrometers provide extremely accurate measurements and machinists often prefer them to other devices such as calipers.
