World No.1 Class of high accuracy, high speed and wide range.
Flagship model for SURFCOM to attain the ultimate perfection level with the linear motor tracing driver as the reference machine
- Linear motor drive ensures high accuracy and high speed movement (patented)
- Low vibration ensures stable measurement at high resolutions (patented)
- Roughness and contour can be analysed in a single measurement
- Large measurement range from 200mm (horizontal direction) and 13mm (vertical direction)
- Can be extended with 2D and 3D surface measurement
SURFCOM CREST adopts an optical fiber-based laser interferometer, one of ACCRETECH's constituent technologies, and incorporates a newly developed highly stable optical path type laser interferometer having a resolution of 0.31nm. This system features a dynamic range as well as a resolution ratio of 42,000,000:1. This means that in a single trace you can evaluate contour profiles in wide ranges and also hidden fine surfaces.
Both surface texture and contour can be measured in a single trace The lineup includes the drive unit tilt handling model with which it is easy to approach the measurement locations
Due to the wide measuring range of 200mm for the X-axis (horizontal direction) and 13mm for the Z-axis (vertical direction), the surface texture and the contour shape can be evaluated once over a broad range with one trace. In addition, with the SURFCOM CREST-T, a model with a drive unit tilt device that can automatically control and tilt the drive unit by ±45°, you can make fine adjustments to the position and posture of the workpiece, and reduce the time and effort required for trial and error to determine whether the measurement point can be approached or not, allowing for more efficient measurement.
The linear motor drive unit (patented) achieves a drive with low vibration and high speed
SURFCOM CREST is equipped with the linear motor drive tracing driver, a patented technology of ACCRETECH. Since it enables high speed drive, the time for approaching workpieces in manual mode, creating CNC programs and drive during CNC measurement is reduced. This improves efficiency throughout the inspection process, from preparation to measurement.
- Z measurement range up to 26mm
- 0.00031µm with 50mm arm
- Precision ±(0.2+|H|/1000)µm with 50mm arm
SURFCOM CREST can be used in all sectors where high precision and resolution are indispensable. It can be used in both the contour and surface sectors due to the special hybrid system, and achieves high end results.
