Surface Roughness Top Ten

July 9, 2025

If you work with precision surfaces, you’ve most likely encountered callouts for surface roughness/surface texture. At first glance, roughness may seem straightforward…you run a roughness gage over a surface, it

Why do seals leak…when Ra meets spec?

June 13, 2025

Surface texture plays a major role in sealing. But just making a surface “rougher” or “smoother” may not improve how well your surfaces seal. Interested in a deep dive into

Let the surface tell you what it wants to be

May 27, 2025

Many surface measurement projects begin with a similar challenge: parts meet specifications, yet some fail while others function. How can we differentiate between the good and poor parts, to understand

I need 3D surface texture measurement (but a new system isn’t in the budget)

April 22, 2025

Measuring surface roughness in 3D can offer a host of benefits. But for many companies, a measurement system may not be in the near-term budget. Here’s a way to reap

My Ra values are different…should I care?

March 25, 2025

The average roughness parameter (Ra, or Sa for 3D measurements) is helpful for spotting changes in a surface or in surface-forming processes. A common question, however, is: how much of
