3. Is there white line, spot or crack on granite surface plate?
It’s normal that there is white line, spot or crack on the natural granite. But We have a lot of processes to test granite material. Our head office is specialized in ultra-precision inspection and control many years. We can not only detect the white lines, spots and cracks on the granite surface, but also detect the internal cracks in the granite!
It is very easy to find white line, crack on granite surface, but it’s very difficult to find the internal crack in the granite. We all worked in precision field and know how importance of precision and stability of granite surface plate. If there is a internal crack on, it will mostly threat our workers’ life. And it will also affect the precision of granite surface plate.
Why many supplier do not make internal inspection in granite even they how importance for precision and stability if there is a internal crack?
(1) . The Inspection cost is too high. They can not afford a suit of inspection devices.
(2) .The material cost is high. Some suppliers will choose bad material only the surface is good even they there is a internal crack. They will try to repair it so the appearance is good but its waste.
Our head office cooperated with German company, and XRD and NDT are our products, which can be used inspection the internal crack in granite!
We can choose excellent material for you!
