Custom Granite Components

Customized granite components have the same physical properties as granite bases and gantry. They are diverse in shape and can meet the design needs of various complex curves, such as arcs, discs, grooves, V-shaped grooves, etc. The processing is relatively difficult and is used in specially designed scenarios, such as differentiated laboratory testing platforms, rotating positioning platforms, photolithography machine platforms, etc.

As equipment continues to iterate and innovate towards high-precision fields, there are more and more differentiated and customized granite components, and precision requirements are getting higher and higher.
