Granite Equal Height Block

Granite Equal Height Block:Precision Foundation for Metrological Excellence

The Granite Equal Height Block is a high-precision metrological tool widely used in manufacturing,inspection,and calibration processes.Crafted from natural granite,this specialized component provides a stable,flat,and uniformly elevated reference surface,making it indispensable for ensuring accuracy in precision measurements and machinery setup.

Design and Material Properties

Granite Equal Height Blocks are characterized by their rectangular or cubic shape with strictly controlled height dimensions,often achieving tolerances as tight as±0.001mm.The primary material,high-quality natural granite—typically black or gray—boasts exceptional properties:high compressive strength(over 200 MPa),low thermal expansion coefficient(around 5-8×10⁻⁶/°C),and excellent wear resistance.Its dense crystalline structure ensures minimal porosity,preventing absorption of moisture or contaminants that could affect dimensional stability.The working surfaces undergo precision grinding and lapping processes to achieve superior flatness(often within 0.002mm per 100mm)and surface finish,ensuring reliable contact with measured components or equipment.

Functional Mechanism

In practical applications,Granite Equal Height Blocks serve as elevated reference platforms.When used individually or in sets,they create uniform height benchmarks for aligning measuring instruments,supporting workpieces,or leveling machinery components.Their high stability minimizes deflection under load,ensuring consistent height references even during prolonged use.The low thermal conductivity of granite reduces temperature-induced dimensional changes,maintaining accuracy in environments where temperature fluctuations are unavoidable.Additionally,the non-magnetic nature of granite eliminates interference with magnetic measurement tools,making them ideal for precision metrology.

Key Applications

Precision Measurement:Used in coordinate measuring machine(CMM)setups,optical comparator stations,and gauge calibration to provide stable reference heights for part inspection.

Machinery Alignment:Applied in the setup of CNC machines,grinding equipment,and assembly lines to ensure components are positioned at equal heights for accurate processing.

Laboratory Calibration:Utilized in metrological laboratories as reference standards for calibrating height gauges,dial indicators,and other precision measuring tools.

Core Advantages

Superior Dimensional Stability:Granite’s inherent properties resist deformation from temperature,humidity,and mechanical stress,ensuring long-term accuracy.

High Precision:Tight tolerances and exceptional flatness make them reliable reference standards for critical measurement tasks.

Low Maintenance:Non-porous surface and wear resistance reduce the need for frequent calibration or replacement,offering cost-effectiveness over time.
