Marble equal height square box is a precision measuring tool made of natural stone (such as Jinan green granite), with the core feature of strictly consistent height on all sides, forming a regular cubic structure. The following are its main uses and characteristics:

Main purpose

1. Precise measurement benchmark

◦ Used to detect the flatness, perpendicularity, and parallelism of workpieces, machine tool workbenches, guide rails, etc., providing a stable three-dimensional reference to ensure measurement accuracy.

As a support platform for marking tools, it ensures the accuracy of positioning during workpiece processing.

2. Equipment installation and calibration

In the installation of machine tools, machinery, and other equipment, it is used for equal height support to ensure that the equipment base is horizontal or vertical, reducing installation errors.

Calibrate the verticality and stability of large equipment such as gantry milling machines and planers to improve machining accuracy.

3. Combination usage scenarios

Multiple equal height square boxes can be combined to form a stable support system, suitable for the inspection or assembly of large workpieces, ensuring consistent height of each support point.

4. Laboratory and Research

As a high-precision experimental platform, it provides a stable support environment without vibration and magnetism for optical instruments and precision equipment.

Characteristics and advantages

High precision stability: Natural stone undergoes long-term aging treatment to eliminate internal stress, achieve uniform structure, low thermal expansion coefficient, and maintain dimensional accuracy for a long time.

Corrosion and Wear Resistance: High surface hardness, acid and alkali resistance, non rusting, suitable for use in harsh environments.

• Non magnetic interference: Non metallic material, avoiding magnetic interference to electronic devices or measuring instruments.

• Impact resistance: Even if it is bumped by heavy objects, only slight damage to the surface does not affect the overall accuracy.

• Easy maintenance: No need to apply oil, simply wipe with a soft cloth during cleaning, low long-term use cost.

Precautions for use

1. Handle with care to avoid collision and damage to corners.

When not in use for a long time, it is necessary to apply oil for maintenance to prevent surface oxidation.

3. Avoid contact with acidic or alkaline cleaning agents and can be wiped with clean water or neutral solution.

4. Regularly calibrate the flatness and perpendicularity to ensure measurement accuracy.
