It uses natural granite from Jinan, which has superior properties compared to commonly used metals.
The natural granite used has undergone changes over millions of years due to the influence of the natural environment, forming a dense mineral particle structure and uniform stone quality. The coefficient of linear expansion is small, and internal residual stress has completely dissipated. The granite components are processed with high precision and do not deform. The material properties, such as vibration damping, chemical resistance, and wear resistance, are also excellent. High precision and high durability with long-term stability CNC machines are achievable. It is used in many fields of industry.
