How tight can machining tolerances really get? Explore the limits of modern CNC precision, from everyday shop tolerances to sub-micron ultra-precision machining and what it really takes to achieve them

Machining glass is rare but impactful. It is challenging to do, but the value that it adds is tremendous. Custom optical elements are an example of manufacturing glass parts using CNC machining.

Optical Coherence Tomography is a non-destructive metrology method that is used for measuring the internal structure of objects that are transparent to light similar to a white light interferometer.

From smarter design to better material choices, these practical tips can help us save time, money, and headaches.

Not sure which steel alloy fits your part? From stainless to tool steels, the right choice depends on more than just strength. Here's how to pick smart—and avoid costly mistakes.

Once we’re working with more than one part, tolerance analysis is essential—small variations can add up and cause fit or alignment issues.

Aluminum is perfect for precision parts—lightweight, corrosion-resistant, and easy to machine. It’s great for prototyping too. But which alloy fits your application best?

Metal 3D printing is a powerful process that enables complex, high-performance parts. But it’s costly, limited in materials, and not easily scalable. Here’s when it makes sense—and when it doesn’t.
