Crysta-Apex S 500/700/900/1200 Series-191- Standard CNC CMM

Series 191
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.

Main Unit
Startup System

This machine incorporates a startup system
(relocation detection system), which disables operation when
an unexpected vibration is applied or the machine is
relocated. Be sure to contact your nearest Mitutoyo
prior to relocating this machine after initial installation.
