Product Overview

In the world of ultra-precision engineering, stability is everything. The Precision Granite Optical Base is a cornerstone component engineered to provide the ultimate foundation for sensitive equipment. Custom-manufactured from ZHHIMG’s proprietary high-density black granite, this component is designed to withstand the extreme demands of high-speed optical positioning, laser measurement, and precision automation systems.

Unlike standard cast iron, granite naturally absorbs vibrations and possesses virtually zero thermal expansion. This custom granite base ensures your high-value optical or laser equipment maintains nanometer-level accuracy, regardless of environmental fluctuations. Whether you are building a 3D laser measuring machine, a high-speed linear motor platform, or a semiconductor inspection system, this granite foundation provides the uncompromising stability your technology demands.

Core Technical Advantages

• Extreme Vibration Damping: Granite’s internal crystalline structure dampens external vibrations up to 60 times faster than cast iron, protecting delicate optical lenses and laser sensors from environmental noise.
• Thermal Stability: With an incredibly low coefficient of thermal expansion, this base remains dimensionally stable even when subjected to temperature swings in industrial environments.
• ZHHIMG® Proprietary High-Density Stone: We strictly use our high-performance black granite (density ≈3,100 kg/m³). Unlike cheaper marble substitutes, our granite guarantees superior physical stability and longevity.
• Nanometer-Level Precision: Machined using advanced CNC technology and hand-finished by master craftsmen with 30+ years of experience. Flatness and parallelism are controlled to the micron level, ensuring perfect alignment for your assembly.
• 100% Customization: We don't just sell standard sizes; we are a professional OEM/ODM manufacturer. We tailor the shape, dimensions, hole patterns, and accuracy grades (e.g., DIN 876 Grade 0) strictly to your specific application.

Quality Control

We use various techniques during this process:

● Optical measurements with autocollimators

● Laser interferometers and laser trackers

● Electronic inclination levels (precision spirit levels)

Quality Control

1. Documents together with products: Inspection reports + Calibration reports(measuring devices) + Quality Certificate + Invoice + Packing List + Contract + Bill of Lading(or AWB).

FAQ

Q: Why should I use granite instead of metal or mineral casting for my optical base?
A: Granite naturally dampens vibrations, resists corrosion, and does not burr. Most importantly, its low thermal expansion coefficient means your precise alignments won't drift as the factory temperature changes throughout the day.

Q: Can you customize the threaded holes and shapes on this base?
A: Absolutely. As a professional manufacturer, we can drill, tap, and embed threaded inserts (such as stainless steel or M6/M8) anywhere on the granite base according to your 2D or 3D drawings.

Q: What accuracy level do you guarantee?
A: We can meet international standards including DIN 876, JIS, and BS817. For ultra-precision optical requirements, we can guarantee accuracy up to 1 micron per meter or better, verified by our Swiss WYLER and Renishaw laser interferometer measurement systems.

Q: Are you a factory or a trading company?
A: Zhonghui Group (ZHHIMG) is a professional manufacturer with a 200,000m² production facility, advanced grinding equipment, and ISO 9001/CE certifications. We control the entire process from raw stone selection to final measurement.
