The digital microscope is a vital component of the West Cerchar Abrasivity Index Tester. It is used after the testing process to measure the width of the wear flatness on the stylus tip surface. The digital microscope features an indenter holder, digital micrometers, an XY stage, a video camera, and dedicated video software (PC not included).

The central role of the digital microscope is to reveal the amount of wear on the stylus, which is a critical parameter in determining the abrasiveness index, known as the Cerchar Abrasivity Index (CAI). The wear on the stylus is directly proportional to the abrasivity of the rock sample tested. By accurately measuring this wear, the digital microscope allows for a precise calculation of the CAI.

The microscope’s capabilities, including its digital micrometers and video camera, ensure high-resolution imaging and precise measurements, contributing to the accuracy and reliability of the testing process. It is, therefore, an indispensable tool in the rock abrasivity testing workflow facilitated by the West Cerchar Abrasivity Index Tester.
