Precision Granite Base Plate for Ultra-Precision Equipment
Granite has become the preferred material for precision bases due to its inherent advantages over metal and composite structures. ZHHIMG takes these advantages further by using high-density black granite (≈3100 kg/m³) with verified physical properties that exceed common European and American granite grades.
Key material benefits include:
• Excellent dimensional stability over time
• Very low thermal expansion
• Natural vibration damping
• High stiffness without internal stress
• No aging, no deformation, no magnetic interference
This makes ZHHIMG granite base plates especially suitable for equipment that requires micron- or sub-micron-level accuracy over long operating cycles.

Each ZHHIMG precision granite base plate is produced in our controlled manufacturing environment using a combination of CNC machining and manual precision lapping.
Product features include:
• High-precision lapped working surfaces
• Precisely machined mounting holes, threaded inserts, and reference interfaces
• Flatness and parallelism controlled according to international standards
• Custom hole patterns and structural designs based on customer drawings
• Optional integration with linear rails, air bearings, guideways, or motion components
Our granite bases are not decorative stone products. They are functional metrology-grade components, manufactured and inspected under the same discipline applied to precision measuring instruments.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

One of the advantages of granite is its low maintenance requirement. Proper care ensures long-term accuracy:
• Clean the surface regularly with neutral cleaner or alcohol
• Avoid impact or localized point loads
• Use soft pads or precision supports when installing components
• Periodically verify flatness in critical applications
• Store and operate in a temperature-stable environment when possible
With correct handling, a ZHHIMG granite base plate maintains its accuracy for decades, far exceeding the service life of metal alternatives.
