As the core foundation of ultra-precision manufacturing, black granite stands out for outstanding rigidity, low thermal expansion and strong vibration damping. ZHHIMG, the industry benchmark for ultra-precision products, specializes in custom high-stability black granite structural components and full-series precision granite measuring tools, delivering reliable metrology and equipment base solutions for global high-end industries.
1. Superior Raw Material: Premium High-Density Black Granite
We strictly select high-quality black granite with a density of nearly 3100kg/m³, whose comprehensive physical performance surpasses black granite sourced from Europe and America. With uniform internal texture, fully released natural stress, ultra-low thermal deformation and excellent shock absorption, our granite maintains stable dimensional accuracy amid temperature fluctuations and micro-vibrations.
We firmly oppose the industry malpractice of substituting cheap marble for granite. Marble features low density, poor rigidity and severe thermal expansion, which cannot meet nanometer-level precision requirements for long-term use. Adhering to our customer commitment of No cheating, No concealment, No misleading, ZHHIMG never cuts corners on raw materials to guarantee permanent precision stability for all clients.
2. Two Core Product Lines of ZHHIMG
Line 1: High-Stability Granite Components
Our granite components cover granite machine bases, structural gantries, assembly frames and granite air bearings, all customized to client drawings.
Processing capacity: Our factory’s CNC equipment and overhead cranes support single-piece processing up to 100 tons, with maximum dimensions of 20m length, 4000mm width and 1000mm thickness.
Production strength: Four dedicated granite bed production lines deliver a monthly output of 20,000 sets of 5000mm granite beds, making us the world’s highest-output granite precision manufacturer.
Application scenarios: Widely adopted in semiconductor equipment, PCB drilling machines, CMM coordinate measuring machines, femtosecond/picosecond laser devices, AOI optical inspection equipment, industrial CT, X-ray machines, linear motor platforms, perovskite coating machines and new energy lithium battery testing equipment. The ultra-stable granite base eliminates vibration interference and ensures nanometer-level positioning accuracy for high-precision equipment. 
Line 2: Full-Series Granite Precision Measuring Tools
Our complete range of granite measuring tools serves as standard calibration benchmarks for metrology labs and production workshops: granite surface plates, square rulers, straight edges, V-blocks, parallel blocks and triangular squares.
Ultra-high precision: Our granite surface plates reach nanometer flatness, while all measuring rulers achieve 1μm accuracy, ideal for workpiece inspection, equipment assembly and precision calibration.
Stable measurement reference: Non-magnetic, corrosion-resistant and wear-proof, these tools retain original precision for decades without deformation, becoming essential standard equipment for global third-party metrology institutes and precision manufacturers.
3. ZHHIMG’s Core Manufacturing & Testing Advantages
Advanced Factory Hardware
Headquartered in Jinan with convenient logistics access to Qingdao Port, our total production base spans 200,000㎡, including two manufacturing plants and a 20,000㎡ special stone storage yard. We introduce four ultra-large Taiwan Nantou grinding machines (each valued over USD 500,000) capable of grinding 6000mm-long metal and non-metal precision platforms.
Our 10,000㎡ constant-temperature & constant-humidity workshop features military-grade ultra-hard concrete floors (minimum 1000mm thickness), 500mm-wide & 2000mm-deep vibration-proof trenches around the workshop, and silent overhead cranes to eliminate vibration noise. We also build a dedicated dust-free constant-temperature workshop simulating semiconductor cleanroom standards for high-precision granite component assembly.
World-Class Precision Testing System
We follow our core philosophy: What you cannot measure, you cannot manufacture. Our testing lab is equipped with globally top-tier measuring instruments: German Mahr 0.5μm dial gauges, Mitutoyo micrometers and roughness testers, Swiss WYLER electronic levels and British Renishaw laser interferometers. All calibration devices hold valid certificates issued by Jinan and Shandong Metrology Institutes, fully traceable to national metrology standards.
Our polishing masters carry over 30 years of manual grinding experience, capable of polishing workpieces down to nanometer precision by hand. Their sensitive tactile judgment accurately distinguishes micron-level grinding removal, earning them the nickname “walking electronic levels” from global clients. All employees receive strict metrology training and annual study of global industrial standards including DIN, ASME, JIS, GB, BS and GOST to ensure products comply with international precision norms.
4. Global Qualifications, Cooperation & Brand Strength
ZHHIMG is the only manufacturer in the precision industry holding full ISO9001, ISO45001, ISO14001 and CE certifications. We have registered more than 20 international trademarks and patents across the EU, USA, Southeast Asia and other developed regions via the CCPIT Trademark & Patent Office.
We maintain long-term technical cooperation with world-class universities and metrology institutes: National University of Singapore, Nanyang Technological University, Stockholm University, and national metrology authorities of the UK, France, USA and Russia. Our global clients include Fortune 500 enterprises such as Apple, Samsung, GE and Bosch, plus well-known brands Akribis, Wyler, THK and HIWIN, covering semiconductor, new energy, aerospace and precision machinery industries worldwide.
5. Our Corporate Mission for Ultra-Precision Manufacturing
