Principle of operation of the measuring instrument linear micrometer in millimeter measurement range (range) between 0 (zero) and 25 mm and resolution thousands of millimeters (mm)
The resolution of the micrometer is obtained from the interaction of the ‘micrometric’ thread, machined in the spindle, with the thread of the ‘inner bush’. Generally, the micrometric thread is an inlet and its pitch is 0.50 mm. This means that a complete (360 °) rotation of the drum, and of the spindle that supports it, will produce an advance equivalent to the pitch (fifty cents).
The centesimal reading of this instrument is obtained because of the perimeter of the thimble, where are minted fifty equidistant divisions. A complete turn will produce an advance of 0.50mm and the fifty divisions will sweep the refference line.
The thousandth resolution is obtained by applying the principle of vernier , minted in the sleeve.
