Precision Granite Angle Plate
Built for Ultra-Precision Alignment
In ultra-precision engineering, structural stability determines measurement credibility. Even microscopic deformation can compromise the entire inspection chain.
This precision granite angle plate is engineered to provide a rock-solid 90-degree reference surface for high-accuracy assembly, calibration, and metrology tasks. Thanks to its dense mineral composition and reinforced structural design, it delivers exceptional geometric stability under heavy loads and long operating cycles.
Unlike cast iron fixtures that are prone to rust, stress deformation, and thermal drift, granite fixtures maintain their geometry over time—making them indispensable in advanced manufacturing environments.

■ Exceptional Geometric Stability
Natural granite aging eliminates internal stress, ensuring long-term shape retention.
■ Superior Vibration Damping
The crystalline structure absorbs micro-vibrations, improving measurement repeatability.
■ Thermal Stability
Minimal thermal expansion prevents dimensional drift during temperature fluctuations.
■ Corrosion-Free Operation
Unlike metal fixtures, granite never rusts and requires minimal maintenance.
■ High Structural Rigidity
Triangular rib-reinforced design enhances load-bearing capacity and torsional resistance.
■ Flexible Integration
Pre-machined mounting interfaces enable seamless installation into automated systems.
■ Ideal for Cleanroom Environments
Non-magnetic and electrically insulating properties make it suitable for semiconductor facilities.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q1: What is a granite angle plate used for?
A granite angle plate provides a precise vertical reference surface for inspection, assembly, and calibration of precision equipment.
Q2: Why choose granite instead of cast iron angle plates?
Granite offers better thermal stability, zero corrosion risk, superior vibration damping, and long-term dimensional accuracy.
Q3: How accurate are precision granite angle plates?
Laboratory-grade models can achieve squareness and flatness tolerances within microns, suitable for high-end metrology applications.
Q4: Can this granite angle plate be customized?
Yes. Dimensions, tolerances, mounting hole patterns, and structural configurations can be tailored to project requirements.
Q5: Is it suitable for heavy industrial equipment?
Absolutely. The reinforced rib structure allows it to support large machine components with excellent stability.
