Using high stable raw material of pure black granite, like Jinan black,Indian black, Impala Stable quality control and manufacturing On-time delivery (3/4/5 weeks manufacturing) plus sea/train/air delivery time Reasonable competitive price Professional with export, service and delivery to worldwide for more than 18 years
1. What precision can you make? Have your Measuring Devices been calibrated?
All of our devices have calibration report. We never use the devices that has not been calibrated.We can manufacture high precision according to DIN 876 standard. Our head office are specialized in ultra-precision inspection and control for many years and we have many advance inspection machines
2. Do you have any certificates and Inspection reports?
We have many certificates such as CE, ISO9001...
Each our product will be tested by many times in different time within one week and then we will make report by our Head Office. By the way, our ultra-precision inspection and control technologies are used on Chinese big plane--C919, High Train and big ship. We also cooperate with US Boeing.
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!
4. What should we do when we get granite surface plate?
(1). open the package to check it. If there is any Knocked wounded on the products, do not worry, take photos and video and send them to : serviceatnd-cnc.com.
Our After-service team will contact you within 0.5 hours and deal with it!
(2). If everything is ok, please put your products in constant temperature plant for 24 hours. And then you could use it!
