electrical discharge processing, granite due to its physical properties has distinct advantages that cannot be achieved by cast iron/steel or synthetic stone. The combination of technologies allows for previously unimaginable precision. Other advantages of granite include high vibration damping, limited expansion coefficient, low thermal conductivity and a weight ratio close to that of aluminum.

We provide granite materials of different origins and properties, suitable for different industries and needs, such as Jinan black and Indian black. Utilizing the grinding technology and expertise cultivated in the processing of various granites, we can also respond to high-precision processing of special materials.
