High Accuracy Granite Machine Base with Threaded Inserts
ZHHIMG offers granite precision components manufactured from high-quality black granite. Each piece is carefully processed by advanced CNC machining and hand lapping to achieve exceptional flatness, straightness, and perpendicularity that comply with international standards.
Granite has unique advantages over traditional cast iron or steel parts, including high density, hardness, and low thermal expansion, ensuring long-term dimensional stability and resistance to deformation.
This component is designed with threaded inserts and can be customized with threaded holes, air-bearing holes, T-slots, and mounting interfaces. It is widely used in ultra-precision machines, measuring equipment, automation systems, semiconductor tools, and research laboratories.
