Micrometer Operating Principles
Micrometer Operating Principles A micrometer is a device that uses a graduated screw mechanism to produce precise linear displacement of a spindle along its axis. Distance measurement is achieved referencing the linear displacement of the spindle to a fixed measuring face on
