CNC GRANITE BASE
A granite surface plate is a workbench or datum plane made of natural granite with an extremely flat surface. It is mainly used as a reference plane for precision measurement, providing a stable and accurate reference origin for various measuring tools (such as height gauges, micrometers, coordinate measuring machines (CMMs), etc.). In the CNC (Computer Numerical Control) machine tool and precision machinery industries, it is also often used as a core component for machine tool bases, guide rails or worktables.

Precision Core: The Art of Calibrating High-Precision V-Blocks
In the world of precision measurement, stability is everything. ZHHIMG adopts high-density (3100kg/m³) natural black granite with a Mohs hardness rating of 6–7, completely eliminating the troubles of rusting and magnetization. Every pair of V-blocks undergoes rigorous matched lapping, ensuring that the parallelism between the 90° included angle and the reference surface reaches the micron-level limit. It is the most reliable reassuring choice for your laboratories and workshops.
