Depth Micrometer

      The depth micrometer is a measuring tool that converts rotary motion into linear motion based on the principle of screw pair rotation.
Its structure includes differential cylinder, fixed sleeve, measuring rod, base, force measuring device, locking device and other parts, as shown in the figure: Schematic diagram of the depth micrometer structure.
In mechanical processing, the depth micrometer is mainly used to measure the depth, step and other dimensions.
