The History of Gauge Blocks

At our equipment calibration facility, the experts in our state-of-the art metrology lab know the importance of precision firsthand. One measurement that is critical in many industries but seldom touched on is gauge blocks, which have been a primary tool for accurately measuring dimension for over a century.

The earliest set of gauge blocks for accurately representing practical lengths is credited to Swedish machinist Edvard Johansson, who developed them in 1896. He demonstrated the blocks in Stockholm during an engineering conference in 1917, during which the blocks performed accurately with 200 lbs suspended from the lower block.

In the time since then, gauge blocks have become significantly more sophisticated. From changes in materials to the way that gauge blocks are created and checked for accuracy, today’s users have access to the most precise gauge blocks in history!

Dealing With Everyday Wear and Tear

As you make use of your gauge blocks, it is important to periodically check them for continued accuracy. Like any precision instrument or measuring device, gauge blocks require routine service and attention.

When you use your gauge blocks while setting up equipment or checking your other measuring tools, the application of pressure to the gauge block is a natural component of the process. Over time, however, this pressure can result in friction that can result in a loss of material that impacts the accuracy of your blocks or causes the opposing sides of your blocks to go out of parallel.

Gauge blocks in use

It goes without saying that if your blocks are no longer accurate, then the accuracy of your machinery or measurement tools that you set with those blocks will suffer, too. To ensure that everything continues working as it should, it’s crucial to have your gauge blocks checked periodically. Based on your usage, our team can help you find a maintenance schedule that’s perfect for your setup.
