Suppose you are measuring with a caliper, then you suddenly get quite confused. You ask, “Why must the aligned line that gets counted on the vernier scale? How that could be?” If you are in a situation like this, this is a good chance to learn it. Vernier scale is the secondary scale that is … Read more
The vernier caliper and other types of caliper that we use today have passed a long story before. Some say it was from East, some say it was from West. Each of them has their own argumentation. Starting from the old-style without vernier scale, now, it becomes vernier scaled. Even, they have transformed into a … Read more
The invention of tape measures has a very unusual history. Sometimes you never know, two completely different things which may have no connection can have a connection. The invention leads back to the time where the hoop skirts were gaining a lot of attention in the fashion industry. The tape measure is an end product … Read more
You may have heard “carbide-tipped anvil” several times when searching for micrometers especially when reading the detail product information. Also, you might realize that all the recommended micrometers for reloading we advise are carbide tipped on the measuring faces as well. For you who don’t know about it; you might more often hear steel, then … Read more
When it comes to a micrometer for reloading, it means a micrometer with a spherical (ball) anvil. This micrometer is meant to measure the cartridge neck wall thickness with higher accuracy. The ball anvil type generates less error because the contact area between the anvil and the wall is small. People also use digital caliper … Read more
As a critical measuring tool for accurate and precise measurement, a micrometer must have a periodic calibration. The calibration will assess the micrometer’s accuracy. If it is out of a certain tolerance, you may need to replace it with the new one. It’s not only about testing the length measurement but also the flatness and … Read more
Zeroing in micrometer is the process of adjusting the index line to line up straightly mark “0” of the thimble scale when the measuring faces of the micrometer are closed properly. In basic terms, it’s a way in order for the measuring tool to get repaired its zero error. How to zero a micrometer is … Read more
After you learn how to use the micrometer, the next basic is how to read the micrometer or taking the reading. The unit system that’s used in micrometers has two versions. Therefore in this page, we cover how to read a micrometer in those two versions: metric (mm) and imperial (inch). Reading a micrometer is … Read more
The first time using a micrometer, you may get a little stunning fuzzy because you don’t know what to start from. Can’t keep silent, you decide to try measuring. Stop it, please! You could ruin the micrometer’s accuracy because rotating the thimble too tight. Using a micrometer is actually easy. There are only some steps … Read more
In short, the idea behind how micrometers work is a combination of these two: the working principle of the differential screw and the distance magnifying that is affected by the thimble diameter. In this page, we only explain the micrometer working principle of the mechanic type one. Differential Screw According to Wikipedia, “A differential screw … Read more
