Depth micrometer is a measurement tool that is used to measure depths of slots and steps. This is one of the most accurate mechanical devices in common use. Depth micrometer will give you the exact measurement of an object that you measure.
When you are measuring an object by using a micrometer, there are some steps that you have to do in order to read a depth micrometer that you use. The first thing that you have to do is measure the spindle for this micrometer. In this case, a micrometer may have come with a set of spindle, select one and measure (in mm) the length of the spindle from the end to the beginning of the shank that is where the spindle widens.
Then, insert the spindle shank into the bottom of the depth micrometer. The bottom of the micrometer is where the “scale” piece is attached. The scale extends out from the body of the micrometer looks like a handle on a sword. The spindle will fit into a small hole beneath the scale that has a locking knob extending from beneath the scale. Turn the knob until you feel the spindle lock into place.
After that, hold the depth micrometer upright by grasping the grip above the thimble. The grip is the first cylinder of the micrometer which has a grip etched into its surface but no numbers. The thimble is a smooth shaft with a series of measured marks running horizontally around the bottom where the shaft of the thimble fits over the sleeve. The sleeve is the smooth shaft with numbers marked vertically on its surface.
The next thing that you have to do in reading depth micrometer is turning the ratchet knob that is centered in the very top of the micrometer above the grip. Depending on which way you turn the ratchet knob, the spindle will extend or retract. And then, balance the sword handles of the scale on the top of the depression you wish to measure. Turn the ratchet knob until the spindle is extended to the bottom of the depression.
The last thing that you have to do in reading depth micrometer is writing down the number on the sleeve that the bottom of the thimble is lined up with. Now add that measurement to the original measurement of the spindle. Add to that sum the measurement of 0.005mm (which is the industry standard width of the spindle locking knob). The result will be a precise measurement of the depth of your depression.
However, there are many choices of depth micrometer that you can consider. one option that you can take into your consideration when you are shopping for this tool is KD Tools 3746 Depth Micrometer – Base 4-Inches.
