Granite Angle Plate with Tapped Holes
ZHHIMG® precision granite right-angle bend plates are core reference components in high-precision industrial fields. The right-angle accuracy can reach the micron level, and both the flatness and perpendicularity meet the requirements of high-end precision manufacturing/measurement. They feature a standard L-shaped right-angle structure, with a dense array of threaded mounting holes on the surface for fixing precision equipment, jigs, or serving as measurement references.

Choosing ZHHIMG® means choosing precision, stability, and reliability. Our products have become synonymous with industry standards, and our partnerships with Fortune 500 companies prove our strength.
-
Granite mechanical components
Adhering to the billion-year stability of the natural “Jinan Green” granite, ZHHIMG, through meticulous research and strict quality control, builds micron-precision bases for three-coordinate measuring and semiconductor equipment. With the quality as solid as a rock, it defines the “anchoring needle” of the precision industry.

Precision Granite Square Ruler Set with Aluminum Case
In ultra-precision manufacturing, even a tiny angular deviation can lead to serious alignment errors. A reliable reference square is therefore essential.
ZHHIMG® granite square rulers are manufactured from high-density ZHHIMG® black granite (≈3100 kg/m³) and carefully hand-lapped by experienced technicians to achieve extremely precise right-angle geometry.
-
granite inspection plate with stand
In mechanical machining and precision fitting assembly, granite or cast iron surface plates—when used in conjunction with adjustable height stands—serve not only as a stable datum plane but also as the foundational element of a high-precision, three-dimensional metrology and manufacturing environment.
-
High-Density Granite Measuring Platform
ZHHIMG® granite bases, with their exceptional density and stability, are the ideal choice for high-precision industrial applications. Their solid structure and durable surface ensure stable performance even in the most demanding environments.
-
Precision Granite Square Ruler
In the pursuit of micron-level precision in the installation and commissioning of sophisticated equipment, ZHHIMG granite squares, with their outstanding stability and extremely low coefficient of thermal expansion resulting from billions of years of natural aging, provide impeccable verticality and straightness benchmarks for CNC machines, semiconductor equipment, and three-coordinate measuring machines. Their natural properties of high Mohs hardness, non-rusting, and non-magnetization ensure that they maintain a constant accuracy of grade 00 or above even in complex assembly environments, helping you build the precise soul of your equipment from the ground up.

Ultra-Precision Granite Component
The Rigid Core for New Energy Inspection
In the world of sub-micron manufacturing, your equipment is only as good as its foundation. ZHHIMG® provides the world’s most stable Black Granite Components, trusted by Fortune 500 giants like Apple, Samsung, and Bosch. -
Granite Straight Ruler
In semiconductor and high-tech manufacturing, dimensional accuracy is specified not in millimeters, but in micrometers—and increasingly in nanometers. During critical processes such as photolithography, wafer defect inspection, and ultra-precision assembly, even sub-micron mechanical deformation of metrology components can induce significant process drift, yield loss, or device failure.
The ZHHIMG granite straight edge is engineered to serve as a stable, thermally invariant, and geometrically traceable primary reference standard—establishing an unambiguous baseline for precision alignment and measurement.
