Measuring With Outside Micrometer
PRODUCTS
If you are a machinist, manufacturing, or engine professional, exact measurements are an everyday must. When it comes to measuring cylindrical or spherical objects, an outside micrometer would be the best tool to use. A well calibrated micrometer can be difficult to use, but with patience and practice, this tool can be a part of your skill set.
1Familiarize yourself with the anatomy of a micrometer. Some parts are stationary while others are movable.
- Ratchet stop
- Thimble
- Frame
- Thimble lock
- Spindle
- Anvil
- Sleeve
Clean the anvil and spindle before beginning. Use either a clean sheet of paper or soft cloth, and hold it between the anvil and the spindle. Gently twist and close on the sheet or cloth. Slowly, pull out the sheet or the cloth.[1]This practice isn't a necessary step for measuring, but keeping the surfaces of the anvil and spindle clean ensures precise measurements.
Hold the object in your left hand and place it against the anvil. The anvil is stationary and can withstand more pressure than the spindle. Make sure the object doesn't move or scratch the surface of the anvil.
Hold the micrometer with your right hand. The frame will rest gently on your palm.You can also fasten the frame on a stationary vise; this helps free up both hands for the measuring process.
Spin the ratchet counter clockwise. Be sure the 0 on the thimble is lined up with the scale on the sleeve.
Twist until the spindle is against the object. Apply enough force. The thimble often clicks. Three clicks is a good stopping point.
Set the thimble lock while the micrometer is still on the object. Even though it is on lock, the spindle can still be moved.
Slide out the object carefully. Be sure to avoid scratching either surfaces of the anvil or spindle; the slightest scratch can ruin the micrometers measuring accuracy.
Write down the measurements before unlocking the spindle. If the spindle loosens, be sure to re-measure.
