Large surface plate
Your surface plate, that big, flat rock sitting in your temperature-controlled inspection lab, is the foundation upon which many--if not all--of your dimensional measurements stand. Of course, it’s also well guarded by your inspection lab manager. Selecting and caring for a granite surface plate is key to ensuring that your products’ dimensional specifications are as accurate as possible.
A very flat rock
Due to its physical properties, such as surface hardness and low thermal expansion, granite is the material of choice for surface plates when tolerances are critical.
We will use Chinese best granite-- Black Jinan granite, which is academy black, according to our customers’ requests or drawing to manufacture granite machine base, granite surface plate, special granite measuring tools and granite air bearings for them. We could make granite surface plate with maximum size 10000*8000*800mm.
