(1) How to install the grinding wheel
Whether it is a cutting blade or a grinding blade, you must ensure that it is installed correctly when fixing it, and check whether the bearing and the nut lock ring are adjusted correctly. Otherwise, the installed grinding wheel may be unbalanced, shaken or even knocked during the working process. Check that the diameter of the mandrel must not be less than 22.22 mm, otherwise the grinding wheel may be deformed and damaged!
(2) Cutting operation mode
The cutting blade must be cut at a vertical angle of 90 degrees. As shown in the figure below, it must be moved back and forth during cutting and cannot be moved up and down to avoid overheating due to the large contact area between the cutting blade and the workpiece, which is not conducive to heat dissipation.
(3) The cutting depth of the cutting piece
When cutting the workpiece, the cutting depth of the cutting piece should not be too deep, otherwise the cutting piece will be damaged and the center ring will fall off!
(4) Grinding disc grinding operation specification
First of all, there are two situations where the grinding plate is used for grinding: flat grinding and edge grinding. However, the grinding angle is an ideal angle of 30 degrees, otherwise the operator will feel that the grinding piece is softer and the service life is shorter. Less than 30 degrees will make the grinding disc harder and longer life. This is because the grinding plate is related to the size of the contact surface, which will definitely affect the grinding efficiency of the grinding plate!
It is worth mentioning that under the best conditions, with suitable motor power and universal hardness grinding wheel, 400-500 grams can be removed within 10 minutes. Under the best conditions, using suitable motor power and universal hardness grinding wheels, surface grinding can remove 280-330 grams within 10 minutes.
Note: Different workers will have different effects, different strengths and operating methods.
(5) Recommendations for cutting and polishing operations
In order to ensure the safety and effectiveness of the construction operation, please ensure before the operation:
-The grinding wheel itself is in good condition, and the protective cover of the power tool is installed firmly.
-Employees must wear eye protection, hand protection, ear protection and work clothes.
-The grinding wheel is correctly, firmly and steadily installed on the power tool, while ensuring that the speed of the power tool will not be higher than the maximum speed of the grinding wheel itself.
-The grinding wheel is a product purchased through the manufacturer's regular channels of quality assurance.
-The cutting blade cannot be used as a grinding blade.
-Do not use excessive force when cutting and grinding.
-Use a suitable flange and do not damage it.
-Before installing a new grinding wheel, be sure to turn off the power supply of the power tool and unplug the socket.
-Leave the grinding wheel idling for a period of time before cutting and grinding.
-Store the grinding wheel correctly and place it when not in use.
-There are no obstacles in the work area.
-Do not use cutting blades without reinforcing nets on power tools.
-Do not use damaged grinding wheels.
-It is forbidden to block the cutting parts in the cutting seam.
-When stopping cutting or grinding, the click speed should stop naturally. It is strictly forbidden to manually apply pressure to the grinding disc to prevent it from rotating.
