——Integration scheme of high-precision benchmark and scene adaptation

1、 Overview of the Plan

The circular marble platform is a precision reference tool based on natural granite or artificially synthesized stone, used for circular workpiece inspection, rotating equipment calibration, and decorative scenes. This plan provides full cycle support from selection, installation to maintenance, ensuring stable performance and cost optimization.

2、 Core advantages

1. Accuracy guarantee

The flatness reaches 0.005mm/m (level 00), meeting the ISO 230-1 standard;

Natural granite has a low coefficient of thermal expansion (about 8 × 10 ⁻⁶/℃) and is suitable for constant temperature environments.

2. Multi functional adaptation

Equipped with T-shaped groove/threaded hole design, compatible with fixture and sensor installation;

Support customization of special features such as V-shaped grooves and scale lines.

3. Long term stability

Natural stone has undergone billions of years of aging treatment, resulting in complete release of internal stress;

Corrosion resistant, non-magnetic, suitable for electronic component testing.

2. Key factors for selection

• Testing requirements:

◦ Precise measurement using a natural granite platform of grade 00;

Workshop calibration can be performed on level 0 or level 1 cast iron/synthetic stone platforms.

• Workpiece size: It is recommended that the platform diameter be 1/3 to 1/2 larger than the workpiece.

• Additional features:

T-shaped groove (fixture installation), V-shaped groove (cylindrical positioning), central threaded hole (rotation axis fixed).

4、 Typical application scenarios

1. Industrial testing

Mechanical manufacturing: gear coaxiality testing, bearing raceway roundness measurement;

Aerospace: dynamic balance testing of turbine blades, installation benchmark of gyroscopes;

Electronics industry: semiconductor wafer curvature detection, optical component parallelism calibration.

2. Precision manufacturing

• Flatness calibration of rotating worktable;

Regular calibration benchmark for coordinate measuring machines.

6、 Customized services

1. Function customization:
