Contour Measuring Instrument

Measuring principle

The measuring principle of this instrument is the rectangular coordinate measuring method ,through X-axis, Z-axis sensor, mapping the surface contour coordinates point of the part under test, data transmission the coordinates point to the upper PC by electrical components. To do the mathematical treatment on the original collected coordinate data by software, marked with the required engineering survey projects

Technical features

The machine reference table and Z-axis column material are made of natural granite, the structure is not deformed, and the performance is more stable and reliable

The use of X-direction and Z1-direction high-precision grating sensors improves the degree of automation and realizes the measurement function that the sensors can automatically contact

The key components adopt special stress-relief alloy materials and special stress-relief treatment process, and the durability and accuracy are kept longer.
