Precision Surfaces

• Lapped to international standards such as DIN 876, JIS, ASME, GB, and BS817
• Flatness can reach sub-micron or nanometer-level depending on application requirements

Metal Inserts & Assembly Interfaces

• Stainless-steel inserts embedded 0–0.02 mm below the surface
• High-strength bonding techniques ensuring permanent stability
• Custom hole patterns, rails, cable channels, and vacuum channels available

Metrology Assurance

All finished components are measured using:

• Switzerland WYLER electronic levels
• British Renishaw laser interferometers
• German Mahr 0.5 µm indicators
• Mitutoyo digital metrology instruments

Calibration is traceable to national metrology institutes.

Granite machine bases require minimal maintenance. To maintain long-term accuracy:

Routine Cleaning

• Clean surfaces regularly using alcohol or pH-neutral cleaning solutions
• Avoid oil-based cleaners that may penetrate the granite surface

Environmental Control

• Keep the machine base in a stable temperature environment
• Avoid exposing the granite structure to rapid thermal changes or direct heat sources

Handling & Protection

• Do not place heavy metal tools directly on precision surfaces
• Use protective covers when the equipment is idle
• Avoid point impacts or vibrations from adjacent heavy machinery

Periodic Inspection

• Conduct flatness and alignment verification annually
• Re-lapping can be performed by our certified technicians if needed
