How to avoid safety hazards in the use of diamond grinding wheel?

In order to avoid safety hazards when using diamond grinding wheels, it is necessary to strictly abide by the operating specifications and take appropriate preventive measures. The following are some specific suggestions and measures:

1. prepare in advance

Check the grinding wheel: Before use, be sure to check the appearance of the diamond grinding wheel for cracks, breaks or other damage. If the problem is found, do not use.

Check information: Check the information such as the mark, model and speed of the diamond grinding wheel to ensure that they are consistent with the use requirements.

Working environment: Ensure that the working area is dry, spacious, and away from flammable and explosive materials.

Personal protection: Before use, you need to wear labor protective supplies, such as safety glasses, gloves, protective clothing, etc., and install safety protective equipment.

2. Operation steps

Installation fixture: The diamond grinding wheel manufacturer installs the fixture or fixture device according to the speed of the diamond grinding wheel.

Start the grinding wheel: Turn on the power, start the grinding wheel, and keep the distance of the wheel mouth from the surface of the grinding object 5~10mm. Observe whether there are abnormal phenomena, such as instability of the grinding wheel or noise, should be stopped in time for inspection.

Fixed workpiece: During the grinding process, do not directly touch the grinding material with your hand. It is necessary to use a fixture or fixture device to place the object to be processed and ensure that it is fixed firmly.

Control operation: The operator shall not arbitrarily change the motor speed, and shall not press the grinding wheel or stick out the body part in the grinding wheel or fixture during the grinding process.

3. operation precautions

Correct posture: The operator should stand on the side of the grinding wheel and should not operate in front of the grinding wheel to prevent the wheel from flying out when it fails.

Observation state: In the grinding process, it is necessary to carefully observe the speed of the diamond grinding wheel and the shape of the processed object, the material and the cooling of the diamond grinding wheel.

Familiar with the equipment: The operator must be familiar with the operation of the equipment, such as the start and stop of the equipment and the speed control device, and must not operate carelessly or illegally.

Dealing with anomalies: When there is an abnormal situation in the grinding process, it is necessary to stop the machine immediately for inspection, and then continue to operate after solving the problem.

4. Maintenance and storage

Power off and isolation: Before maintenance or storage, ensure that the grinding wheel is powered off and isolated to prevent accidental start.

Cleaning and lubrication: Gently clean the surface and working surface of the grinding wheel with a clean cloth or soft brush, and regularly add lubricant to increase the maintenance life of the grinding wheel.

Check for cracks: Check the surface of the grinding wheel regularly for small cracks to avoid safety hazards caused by grinding wheel rupture.

Storage conditions: Diamond grinding wheel should be stored in a dry place, avoid contact with raw oil, alkane and other substances, indoor temperature should not be less than 5°C.

By following the above measures and precautions, you can greatly reduce the safety risks when using diamond grinding wheels to ensure work safety.
