Prevention measures and use of Granite surface plate

Precautions for use

•  Before use

1. There should be a qualified mark, valid use period or other proof.

2. There should be no defects such as burrs, scratches, bruises, rust, etc. on the measuring surface.

3. The measured part shall not have defects such as burrs, scratches, bumps, scratches, rust, etc.

4. The temperature of the granite surface plate and the device under test should be as uniform as possible to prevent measurement errors.

5. Before use, it should be inspected according to the specified requirements and methods.

• Using

1. During the use, avoid placing heavy objects on the working surface of the granite surface plate for a long time. The granite surface plate used for the first time should be leveled again after two months of the first leveling.

2. The granite surface plate is fragile. During the process of use, it is necessary to avoid excessive collision between the workpiece and the working surface of the platform to prevent damage to the working surface of the platform and affect the accuracy of the working surface.

3. It is forbidden to place overheated workpieces (such as soldering irons) directly on the surface.

4. The weight of the workpiece should not exceed the rated load of the platform, otherwise the quality of the work will be reduced, the platform will be destructively deformed, and the structure of the platform may be damaged, making it unusable.

5. Keep it clean and any stains on the platform may affect the measurement accuracy.

• After use

1. After use, remove the stain on the granite surface plate with a neutral detergent. When cleaning, wipe the surface of the platform with a soft cloth dampened with detergent. After the cleaning is completed, the surface of the platform is free of oil and dirt, and no other particles adhere to it, and the handle is smooth and free from stagnation.

2. Do not use hard brushes and abrasive cleaners.

3. After use or cleaning, the platform should be covered with plastic or plastic sheets to prevent dust pollution and protect the working surface from damage.
