What does a leader in honing and microfinishing do? They find new ways to keep leading. Nagel is one of the most well-known names in high volume honing and microfinishing, with a worldwide presence in auto manufacturing, aerospace, defense, and medical applications. Nagel Precision is a world leader in microfinishing and honing, with extensive expertise … Read more
Do you measure with a skidded stylus? Are you seeing unexpected “dips” in your data? Here’s the irony: those downward features are most likely the result of upward debris on the surface. When the skid raises up over debris, the stylus has to reach down to stay on the surface. That stylus motion shows up as a “dip” in the measured … Read more
We’ve all seen a chart like the one below, showing that very different surfaces can have the same average roughness (Ra) values: An Ra reading from your gage can’t tell you which of those surfaces you made! So, does that mean that Ra is “bad” and that other parameters may be better? Let’s have a … Read more
A while ago we showed you how you can print 3D surface textures directly from OmniSurf3D. Over the last couple of years we’ve been using some 3D printed cylinder bore samples at our talks and teaching sessions… …and a lot of you requested files so that you could print your own. Well…we heard you, and … Read more
Surface texture parameters tell so much about a surface and how it might perform. But just looking at the equations can’t tell us everything we need to know about how to interpret the values. This new, free series of videos helps explain the meaning of dozens of common surface texture parameters in a simple and graphical way. … Read more
Is it really 2–50 UPR? Don’t be so sure! Whether rolling, sliding, sealing, or simply fitting together, round geometries are everywhere. And controlling the shape of these “ideally round” surfaces is critical to their performance. Historically, roundness has been specified and controlled as what can be described as “waviness around a circle.” Higher frequencies are … Read more
