Since 1978, TMMT STONE developed granite surface plate. As a leader in precision granite, we have know-how staff and most experienced engineers and workers. Our dominant position in the market has been achieved through continuous investment, innovation, extensive research and development. Making use of our own quarry we select first-choice blocks. After cutting, milling and grinding by machines, we lap surfaces by hand to guarantee high accuracy. We manufacture a large variety of products for OEM manufacturers of fabricating, assembly and inspection equipment for many industries, such as: semiconductor, electronics, lithography, optical, vision inspection, coordinate measuring machine, fiber optic, flat panel, laser processing, water jet cutting, defence, and many others. Products include surface plates, straight edges, bases and single components to multi-component assemblies, air bearing rails for precision motion control devices, and we are especially proud of ourselves in custom bases, stages, and accessories. We can meet your needs for critical geometry into the sub-micron range and provide intricate structural shapes with state-of-the-art computer controlled equipment. In today** increasingly sophisticated engineering environment, the need for extreme precision has never been greater. To meet costomers*?demanding requirement, we installed a CNC drilling machine to ensure the tolerance between inserts or holes.
