How to ensure the reliability of the Angle grinder circuit

As a common power tool, Angle grinder is widely used in metal processing, cutting and trimming fields. Ensuring the reliability of its circuit can not only improve the work efficiency, but also ensure the safety of the operator. Here are some key measures to ensure the reliability of the Angle grinder circuit:

First, check before use
Check the power cord and plug
Before using the Angle grinder, be sure to check whether the power cord is intact and the plug is loose. The power cable should be a rubber sheathed copper core flexible cable without a connector. If the power cord is found to be damaged or aging, it should be replaced immediately to prevent leakage accidents.
Check the leakage protection
The power socket of the Angle mill must be equipped with leakage protection appliances with rated leakage action current not more than 30 MA and operation time not more than 0.1 seconds. This can effectively prevent electric shock accidents caused by leakage and ensure the safety of operators.
Check switches and carbon brushes
Ensure that the switch action of the Angle grinder is flexible and reliable, and can quickly cut off the power when needed. At the same time, check whether the carbon brush wear is too short, if the carbon brush wear is serious, it should be replaced in time to prevent the spark from being too large or the armature from burning due to poor brush contact.

Second, the use of precautions

Avoid overload operation
The Angle grinder should avoid continuous work for a long time during use to avoid overheating of the motor. If the motor temperature is too high, it should be stopped and rest, and then continue to use after cooling. In addition, do not use the Angle mill for processing tasks beyond its rated power, so as not to damage the equipment or cause safety accidents.
Check circuit connections regularly
During use, the power cable connection should be regularly checked whether it is firm and the plug is loose. If any abnormality is found, it should be stopped immediately to check and repair.

Third, maintenance and maintenance
Replace the carbon brush regularly
The carbon brush is an important part of the Angle grinder and will gradually wear out with use. When the carbon brush is worn to a certain extent, it should be replaced in time to ensure the normal operation of the motor. When replacing the carbon brush, keep the carbon brush clean and ensure that it can slide freely in the clip.
Clean motor interior
Clean the dust and chips inside the motor regularly to maintain the good heat dissipation performance of the motor. This can not only extend the service life of the motor, but also improve its working efficiency.

Check lubrication and transmission components
Check the lubrication and transmission components of the Angle mill, such as gears and bearings, regularly to ensure smooth operation. Timely filling of lubricating oil to the rotating part can effectively reduce wear and extend the service life of the equipment.
Check the leakage protector
Check the working status of the leakage protector regularly to ensure that it can quickly cut off the power supply in the event of leakage. This can be done by regularly testing the sensitivity of the leakage protector.

Fourth, safe operation procedures
Wear personal protective equipment
When operating an Angle mill, you must wear personal protective equipment such as protective glasses, masks and gloves to prevent splashing from harming your eyes, skin and respiratory system.
Install the grinding wheel properly
When installing the grinding wheel, ensure that the grinding wheel has no cracks, cracks or injuries and is firmly installed. Before use, no-load test run should be carried out to check whether the rotation of the grinding wheel is smooth.
Avoid improper operation
Do not unplug the power plug directly under load to avoid damage to the device. At the same time, do not use damaged or aging grinding wheel pieces, and do not attempt to repair the damaged Angle grinder by yourself, which should be handled by professionals.

Fifth, regular testing and evaluation
Performance test
The performance of the diagonal mill is tested regularly, including the measurement of the motor’s power, current, speed and torque. This can help determine whether the Angle grinder meets preset performance requirements and identify potential problems in a timely manner.
Security detection
The safety of the diagonal mill is tested, including the integrity of the protective device, the reliability of the switch and the safety device. This can effectively prevent safety accidents caused by improper operation or equipment failure.
Electrical insulation performance test
Regular electrical insulation performance tests are conducted to ensure that the insulation materials of electrical components can effectively isolate the current and prevent electric shock accidents.

The above measures can effectively ensure the reliability of the Angle grinder circuit and improve the safety and service life of the equipment. I hope this information can help you better maintain and use the Angle grinder to ensure safe operation.
