Mitutoyo CRYSTA Apex S574 CMM
ACCURACY: 1.7 μm 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 othr CMMs offering *E0, MPE of approximately (2.5+4L/1000) µm.
For example, if the 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.
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).
From sensors installed on each axis scale and working in conjunction with sensors placed on the work-piece,
temperatures are obtained before outputting the measurement result to the controller.
Thermal compensation is applied based on 68 °F (20 °C), taking into account the work-piece material expansion coefficient.
The combined axis scale/work-piece temperature compensation design used on the CRYSTA-Apex S gives superior results compared to systems with sensors only on the axis scales.
HIGH SPEED ACCELERATION DRIVE
- Model
CRYSTA-Apex S
The CRYSTA-Apex S Series offers a maximum drive speed of 693mm/s (27.2″/s) [1600/2000Series], and a maximum acceleration of 2,309mm/s2 (7.57″/s2) [500/700/900 Series], resulting in an increase of almost 270mm in drive distance in one second, when compared with general-purpose CNC coordinate measuring machines (with a maximum speed of 430mm/s (16.9″/s) and a maximum acceleration of 1,667mm/s2 (5.46″/s2).
Furthermore, with a maximum measuring speed
(i.e., the speed with which the stylus tracesover the workpiece) of 8mm/s (0.31″/s), the CRYSTA-Apex S produces measurements more quickly than ordinary CMMs (with a maximum measuring speed of 5mm/s (0.19″/s).
Combining high speed and high acceleration, the CRYSTA-Apex S reduces measuring time. As the number of measuring points increases, measuring costs per point are further reduced.
Condition: Shows minimal signs of usage, well taken care of!
