CRYSTA-Apex S Series

High accuracy in the 1.7μm class
The CRYSTA-Apex S is a high-accuracy CNC coordinate measuring machine that guarantees a maximum permissible error of *E0,MPE = (1.7+3L/1000)μm [500/700/900 Series]. Comparing the CRYSTA-Apex S with CMMs offering *E0,MPE of approximately (2.5+4L/1000)µm where a required tolerance on a dimension is ±0.02 mm, then the measuring machine uncertainty should be no more than one-fifth (ideally one-tenth) of that, i.e. 4μm. 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.
