High Accuracy in the 1.7um Class


The CRYSTA-Apex S is a high-accuracy CNC coordinate measuring machine that guarantees a maximum permissible error of *E 0,MPE = (1.7+3L/1000)μm (500/700/900 Series). Let's compare the CRYSTA-Apex S with CMMs offering *E 0,MPE of approximately (2.5+4L/1000)um. If, for example, the required tolerance on a dimension is +/-0.02mm, then the measuring machine uncertainty should be no more than one-fifth (ideally one-tenth) of that, i.e. 4um. This means that with a general-purpose CMM, when the measured length exceeds 14.8" (375mm), machine uncertainty exceeds one-fifth of the dimension tolerance in this case. In contrast, as shown in the figure on the right, with the CRYSTA-Apex S the measurement uncertainty remains within one-fifth of the dimension tolerance up to 30.2" (766mm). The higher accuracy specification of the CRYSTA-Apex S therefore gives it more than double the effective measuring range in terms of accuracy-guarantee capability in this case. *ISO 10360-2:2009

Temperature Compensation System

The CRYSTA-Apex S comes equipped with a temperature compensation system that guarantees the accuracy of measurement under temperature conditions of 60.8 to 78.8 F (16 to 26 C). This system, based on permanently installed temperature sensors of each scale working together with sensors placed on the workpiece, monitors scale and workpiece temperatures and, monitors the temperature and, before outputting the measurement result to the controller, corrects it to the value that would be measured at 68 F (20 C), taking into account the workpiece material expansion coefficient as well as the CMM's characteristics. The combined scale/workpiece temperature compensation scheme used on the CRYSTA-Apex S gives markedly superior results compared to systems that only compensate for scale temperature.
