What is a micrometer?

Micrometer is a precision measuring tool used to measure the thickness, diameter, depth and other dimensions of an object. Its measurement range is generally between a few millimeters to tens of millimeters, and the accuracy can reach 0.01mm or even higher. The 0-25mm micrometer is one of the commonly used models, suitable for measuring smaller size workpieces.

0-25mm Micrometer Features and Advantages

The 0-25mm micrometer has the following features and advantages:

• High precision : The measurement accuracy is as high as 0.01mm, which can meet the needs of most precision measurements.
• Strong reliability : Made of high-quality materials, durable and not easy to deform.
• Easy to operate : Simple structure, convenient operation, suitable for beginners.
• Wide application range : Not only can it be used for metal workpieces, but also for the measurement of various materials such as plastic and wood.

Precision guarantee in machining

In the machining process, 0-25mm micrometer is often used to measure the outer diameter, inner diameter, thickness and other dimensions of parts to ensure machining accuracy. Whether it is a lathe, milling machine or grinding machine, the micrometer is an indispensable measuring tool.

Key Tools in Engineering Inspection

In engineering inspection, 0-25mm micrometer is widely used in the quality inspection of buildings, bridges, pipelines and other projects. It can quickly and accurately measure the size of components to ensure construction quality and safety.

Importance of Materials and Processes

High-quality materials and exquisite craftsmanship are the key to ensuring the accuracy and durability of the micrometer. The following points should be paid attention to when choosing:

• Material : Preferably stainless steel or chromium alloy material, these materials have good corrosion resistance and wear resistance.
• Surface treatment : The surface is smooth and burr-free, and it is finely polished to reduce measurement errors.
• The scale is clear : The scale line should be clearly visible for easy reading.

Brand and Price Balance

There are many brands of 0-25mm micrometers on the market at different prices. Brand reputation, product quality and price should be considered in the selection. Some well-known brands such as Mitutoyo, Starrett, etc., although the price is higher, but the quality is guaranteed. At the same time, domestic brands with higher cost performance can also be considered.

Reading method and accuracy

Correctly reading the value of the micrometer is the basis for ensuring the accuracy of the measurement. The specific steps are as follows:

1. Gently close the anvil and micrometer screw of the micrometer to check whether the zero position is aligned.
2. Place the object to be measured between the anvil and the micrometer screw, and slowly rotate the ratchet until you hear a "click" stop.
3. Read the integer part on the main ruler and the decimal part on the secondary ruler, and add them to get the final measurement value.

It should be noted that the line of sight should be kept perpendicular to the scale line when reading to avoid errors caused by parallax.

Preparation and calibration before measurement

Before the formal measurement, the micrometer should be prepared and calibrated to ensure the accuracy of the measurement results:

• Cleaning : Use a clean soft cloth to wipe the anvil and micrometer screw to remove dust and oil.
• zero calibration : completely close the anvil and micro-measuring screw to check whether the zero position is aligned. If there is any deviation, it can be corrected by adjusting the knob.
• Preheating : Place the micrometer in a room temperature environment for a period of time to make its temperature consistent with the ambient temperature to avoid measurement errors caused by temperature changes.

Daily cleaning and anti-rust treatment

Regular cleaning of the micrometer is the key to extending its service life. After each use, the residue on the measuring anvil and the micrometer screw should be removed in time, and a thin layer of anti-rust oil should be applied to prevent rust.

Periodic inspection and calibration

Every once in a while, the micrometer should be fully inspected and corrected to ensure that it is always in the best working condition. It is recommended to submit for inspection at least once a year and be verified by a professional organization.
