Specifications

Micrometer head composition:

     micrometer head by not moving parts installation cover, shaft sleeve and movable part rod, differential cylinder, trimming button composition.

Micrometer head reading and use:

     micrometer head for the installation of the set in the support seat fixed installation, bush on the main rule has two row scale line, marked with digital is the whole mm scribed line (1 mm/case), a different row is half millimeter scribed line (0.5 mm/case); Differential cylinder front circular surface with fifty equant scribed line (0.01 mm/case).

Hand rotation differential cylinder or trimming button, the rod is along the axis direction in a. Differential cylinder every turned 1 case, rod along the axis direction small displacement 0.01 mm, this is also called micrometer head index value.

Micrometer head reading method is read bush main rule on uncovering scale numerical, pay attention to half a millimeter ruling; Read and the main scale horizontal line alignment differential cylinder on numerical value, can read 1/10 dividing micrometer head correct reading: when measuring the length of the object to be tested by the integer part fixed the scale reading, the fractional part by moving part E read (note the value will read a digits) readings special attention should be paid to fixed scale said 0.5 MM scale line is show below:

Micrometer head use:

    micrometer head in the experiment is used to produce displacement and indicates that the displacement of the tool. General micrometer head before use, first turn differential cylinder to 10 mm place (in order to hold rod shaft forward after, the displacement of allowance), then micrometer head shaft sleeve on the main scale horizontal line to install your own to special support seat, mobile micrometer head installation set (micrometer head whole mobile) make rod and measured body connection and measured body in the appropriate position (depending on the specific experiment and decide) to tighten the support seat of fastening screw. When rotating micrometer head differential cylinder, measured body will with the rod and displacement.
