How to End Styli Wear and Build-Up Forever

Diamond styli are an excellent choice for demanding applications

Published: Tuesday, March 19, 2019 - 12:00

(Q-Mark: Rancho Santa Margarita, CA) -- Q-Mark is now offering precision diamond styli in nearly any standard thread size and configuration. Diamond styli are an excellent choice for demanding applications. Diamond sphere performance is unmatched when measuring hard, abrasive, or very soft surfaces.

No more cleaning or build-up

Unlike ruby spheres, no substance sticks to diamond spheres, not even the softest aluminum alloys. Diamond spheres retain their high-precision spherical form at all times, thereby preventing additional measuring uncertainties. This saves you time and money because checking, cleaning, and recalibration are theoretically eliminated.

The hardest substance on Earth

Diamond is the hardest known natural material on Earth. Pure diamonds can only be scratched by other diamonds. Diamonds resist breaking under impact and are impervious to strong acids, bases, and chemical solvents. These beneficial properties ensure that your diamond styli will retain their high-quality spherical form indefinitely. There’s no need to inspect them for wear. 

Another advantage of diamond-coated spheres is their high Grade-5 (less than 150 nm) sphericity. They’re available in more sizes,
and they cost less than solid diamonds.

Which diamond sphere is right for you?

Diamond styli are available in two types: solid diamond, and diamond-coated spheres. Which tip should you use?

Solid diamond spheres should be used when probing hard or abrasive surfaces. The diamond tip will not wear, even when used with high probing or scanning forces. Solid diamond spheres are ground and polished to Grade-10 sphericity (less than 250 nm).

When probing soft alloys, like aluminum, use diamond-coated spheres. No buildup occurs when probing or scanning soft materials with diamond-coated spheres.
