Itieffe is pleased to present this guide on how to make measurements using a micrometer. Micrometer is a precision measuring instrument widely used in various industries, from engineering to metalworking, medical instrument manufacturing to automation quality. Its ability to measure very small dimensions with extreme precision makes it indispensable for ensuring precision and quality in applications where even fractions of a millimeter can make a difference.
This guide is designed to be a useful resource for anyone wanting to learn how to properly use a micrometer. Whether you're a beginner new to this instrument or a seasoned professional looking to perfect your skills, you'll find valuable information to ensure accurate and reliable measurements.
In the guide, we will explore the following key areas in detail:
- Fundamental Concepts: We'll start with an overview of the basic principles of the micrometer, including its essential components and general operation. Understanding these fundamental concepts is critical to mastering the use of the micrometer.
- Measurement Procedure: We will guide you step by step through the correct procedure for making precise measurements with the micrometer. You will learn how to prepare the micrometer, place it on the surface to be measured, read and interpret the readings.
- Common mistakes and how to avoid them: We'll explore common mistakes that can occur when using your micrometer and give you tips on how to avoid them. Precision is essential when it comes to measurements, and you will understand how to keep errors to a minimum.
- Maintenance and conservation: Your micrometer is a precision instrument, so it is essential to know how to maintain and store it in excellent condition.
We are confident that this guide will provide you with the knowledge you need to use your micrometer effectively and accurately. Whether you are working on engineering, manufacturing, or quality control projects, a proper understanding of how to use your micrometer is essential to ensuring success in your precision measurement efforts.
Micrometer – How to take measurements
How to measure with a micrometer
The micrometer is a high precision gauge with sensitivity to the hundredth of a millimeter.
The most common make measurements in mm between:
0-25 / 25-50 / 50-75 / 75-100
| 1- fixed anvil | 6 - graduated compass |
| 2 - measuring faces | 7 - internal micrometric screw |
| 3 - mobile rod | 8 - stand (thermally insulated handle) |
| 4 - locking device | 9 - torque limiter ratchet |
| 5 - line of faith | 10 - graduated drum (vernier) |
How to proceed
- insert the piece to be measured between the measuring faces (1 - 3)
- act on the ratchet (torque limiter or clutch) to match the measuring faces with the piece (9)
- act on the locking device to freeze the measurement (4)
- take the reading between the faith line (5) and the graduated drum (vernier) (10)
Let's see an example
The last notch that can be read on the faith line of the fixed scale (5) corresponds to the value 12.50 mm, while on the graduated or vernier drum (10) you can read 0.31 mm - So the measurement is equal to 12.81 mm.
