Lithium-ion batteries charge and discharge because their lithium ions can move in both directions between positive and negative electrodes.

Sensors are an essential part of a metrology system, and there are several key factors that inform a buyer’s choice. These include ease of use, accuracy, speed and cost. Comparing the options can involve both analysis of features and actual demonstration of capabilities, but to get meaningful information for either you have to ask the right questions.

As part tolerances tighten, both form and surface finish have a bigger influence on the size and function of the product. And with pressures on manufacturing to be more productive, it is no longer viable for checks of surface or form to be performed on a measuring system in a quality room.

How does the surface texture affect the friction between two dry parallel sliding surfaces? It turns out that this problem has challenged some of the greatest minds in science and engineering.

Light and compact, easy to operate with long-lasting battery power, the Jenoptik W10 mobile surface roughness measuring system brings the measurement lab to the shop floor.

Mitutoyo introduced the new Surftest Probe and SurfPak-SP software allowing surface roughness analysis on a Mitutoyo CNC CMM and eliminating the need for workpiece changeover to a second measurement device.

When white light strikes a surface, two different light interactions occur. Gloss or shininess is a geometric attribute related to the scattering of light off the first surface of the material.
