MITUTOYO 103-137 Micrometer 0-25mm 0.01 Ratchet

Mitutoyo 103-137 micrometer is used for accurate measurements down to thousandths of an inch or hundredths of a millimeter to ensure consistency in part dimensions to maintain quality for product performance, safety and reliability. It plays a vital role in measuring small components with high accuracy to facilitate the production of precise parts. This micrometer is ideal for precision engineering, manufacturing and quality control across the automotive, aerospace and electronics industries.

Working Mechanism:

• This mechanical outside micrometer functions by first opening its jaws with a rotating thimble, allowing a workpiece to be inserted between the anvil and the spindle.
• As the jaws close, the spindle moves towards the anvil and the main scale on the barrel displays the whole number measurement.
• Simultaneously, the rotating thimble shows incremental measurements. Aligning the thimble's graduation with the main scale provides precise measurement.
• This process enables accurate and repeatable measurements of outside dimensions, making the micrometer indispensable in industrial settings for tasks, such as quality assurance, production and inspection.

Features:

• It features a resolution of 0.0001 inches, providing precise measurements for outside dimensions.
• This Mitutoyo outside micrometer has a jaw depth of 3.346 inches.
• It comes with a vernier mechanical display for accurate readings of the main scale and vernier scale graduations.
• This micrometer offers a rotating spindle, facilitating easy positioning and measurement of workpieces.
• It is equipped with a carbide anvil for durability.
• This micrometer also features a thimble ratchet to control pressure for accurate measurements.
• It has a steel spindle with a flat shape for stability during measurements.

Frequently Asked Questions:

Q. How do you ensure accurate measurements with a mechanical outside micrometer?

A. To ensure accuracy, handle the micrometer with care, apply consistent pressure when closing the jaws and avoid over-tightening. Regular calibration and maintenance are also essential for accuracy and reliability.

Q. What precautions should be taken when using a mechanical outside micrometer?

A. Avoid dropping the micrometer, ensure the workpiece and measuring surfaces are clean and store the micrometer in a protective case when not in use to prevent damage and maintain accuracy.

Q. What is the purpose of the lock nut on a mechanical micrometer?

A. The lock nut secures the spindle in place once the desired measurement is obtained, preventing accidental movement and the measurement remains consistent during reading and recording.
