At ZHHIMG®, we have access to some of the most advanced CNC machinery in the world. But when it comes to achieving true nanometer-level flatness, technology still needs human intuition. We are incredibly proud of our veteran grinding masters, many of whom have spent over 30 years perfecting their craft. Our clients affectionately call them “walking electronic levels.”
These artisans don’t just operate machines; they feel the stone. Through decades of training under German DIN, American ASME, and Japanese JIS standards, their hands can detect dimensional changes as small as a few micrometers. They know exactly how much material is removed with a single pass. This level of tactile precision ensures that our granite rulers and surface plates consistently achieve tolerances within 1μm.
