Granite Surface Plate INSIZE 6900-A34 Calibration Plate with Stand

Description

Product Overview

The INSIZE 6900‑A34 granite surface plate is engineered for the most demanding calibration tasks where absolute precision and long‑term stability are non‑negotiable. Constructed from a single block of high‑grade granite, the plate is free from internal stresses, ensuring that it will not deteriorate or change dimensions over time. The material’s natural resistance to moisture, chemicals, and temperature fluctuations means that the plate maintains its flatness within micrometer tolerances even when the ambient temperature shifts by several degrees. The plate meets the stringent ggg‑p‑463c specification for thermal stability, delivering minimal dimensional change under thermal load. With a generous working surface, the plate accommodates a wide range of gauges, fixtures, and measurement tools. The model number 6900‑A34 is clearly etched on the underside for easy identification, and the plate is supplied with optional accessories – a sturdy stand (part no. 6902) and a precision jack (part no. 6903) – that allow users to configure the work height and orientation to suit specific workflows.

Usage

Designed for both laboratory environments and industrial settings, this granite surface plate excels in applications such as machine tool inspection, coordinate measuring machine (CMM) verification, gauge block calibration, and precision assembly. In a metrology lab, the plate provides a reliable reference surface for calibrating high‑accuracy instruments, while its low thermal expansion characteristic ensures that measurements remain consistent throughout the day. In manufacturing plants, the plate serves as a stable platform for setting up jigs, fixtures, and tooling, reducing the risk of cumulative errors that can affect product quality. The optional stand and jack enable users to elevate the plate to ergonomic heights, facilitating comfortable work for technicians and reducing fatigue during prolonged use. Whether the environment is a temperature‑controlled cleanroom or a busy workshop, the granite surface plate’s robust construction and optional accessories make it adaptable to a variety of real‑world scenarios.

FAQ

What is the recommended cleaning method for the granite surface plate?

Use a soft, lint‑free cloth slightly dampened with distilled water or a mild, non‑abrasive cleaner. Avoid solvents, acids, or harsh chemicals that could damage the granite surface. After cleaning, dry the plate with a clean cloth to prevent water spots.

How does temperature affect the accuracy of the plate?

The granite material exhibits minimal dimensional change with temperature variations, typically less than 0.2 µm per degree Celsius. For the highest accuracy, allow the plate to acclimate to the ambient temperature for at least two hours before use.

Can the optional stand be used with other surface plates?

The stand (part no. 6902) is specifically designed for the 6900‑A34 model, matching its mounting points and load capacity. While it may physically fit other plates of similar dimensions, using it with non‑compatible plates could compromise stability and is not recommended.

What is the maximum load the plate can support?

The granite surface plate is rated to support up to 150 kg (approximately 330 lb) uniformly distributed load without deformation. Concentrated loads should be avoided to preserve the plate’s flatness.

Is the plate compatible with ISO 9001 calibrated equipment?

Yes, the plate’s flatness and waviness specifications are documented in a calibration certificate that aligns with ISO 9001 requirements, making it suitable for use with calibrated equipment in certified environments.
