Micrometer Have you ever needed to make an extremely precise measurement? Industries that work with small parts and fittings have to make precise measurements. In many places, the measurement should be close to the exact value to avoid potential danger. To obtain such precise and accurate measurements, we turn to micrometers.In this article, let us discuss in detail about the micrometer. Table of Contents: • • • • • • What is Micrometer? A micrometer is an instrument used for making precise linear measurements of dimensions such as diameter, thickness, and lengths of solid bodies. It is made of a C-shaped frame with a movable jaw operated by an integral screw. The fineness of the measurement depends on the lead of the screw while the accuracy of the measurement depends on the accuracy of the screw-nut combination. It is often misunderstood with the micrometer (μm) – the standard unit of length measurement. Another common name used for a micrometer is micrometer caliper due to its similar appearance to the caliper. Parts of a Micrometer A micrometer is composed of the following parts: • Frame– It is the C-shaped body that holds the anvil and barrel in constant relation to each other. The frame is heavy and has high thermal mass. To prevent substantial heating up, it is covered by insulating plastic. • Anvil – The shiny part the spindle moves toward and the sample rests against. • Barrel – Stationary round component with a linear scale on it. • Screw ­– Found insid...

A less popular option, some of the micrometers listed can be purchased as a mechanical counter version. Some of the manufacturers call them digital, but the term is misleading. Personally, I have never found them superior to other mics. I would avoid them. You can expect their accuracy to be in line with a standard micrometer of the same type. Carbide tips provide additional wear resistance for a micrometer, especially one that may see extra heavy usage. While they can be useful in this regard, the carbide tips are more brittle and have been known to chip. For most people, your standard stainless-steel spindle and anvil will be good enough but both types work well. These micrometers have a special anvil and spindle to allow them to measure the opposite sides of a thread. The anvil has a double v shape while the spindle is pointed. They have an overall measuring range such as 0-1” or 1-2” like a standard micrometer but also have a range of threads per inch or mm that they are capable of measuring. Heat can cause metal or other materials to expand. When this happens, your part can appear to measure larger than it actually is. The same principle affects your measuring tool as well. This is why many micrometers will have an insulated grip to keep you from transferring your body heat to the micrometer and affecting the measurements. This attachment allows a standard outside micrometer to function like a tube or rounded anvil mic. The attachments do reduce the overall measuring ...
