What maintenance measures should be paid attention to for brushless angle grinders

Brushless Angle Grinder has become an indispensable tool in many industries such as metal processing, wood cutting and stone grinding due to its high efficiency, energy saving and durability. However, any high-precision power tool will gradually reduce its performance without proper maintenance, and may even cause safety hazards. Therefore, in order to ensure the long-term stable operation of the brushless angle grinder, it is particularly important to implement professional maintenance measures.

Cleaning is the basis of brushless angle grinder maintenance. After each use, the operator should promptly clean the chips, dust and debris on the surface of the machine. These residues will not only affect the operating efficiency of the machine, but may also cause wear to the internal parts. During the cleaning process, it is recommended to use tools such as brushes and air guns to ensure that there are no impurities left on the work surface, guide rails, grinding discs and motor housings. In particular, do not use water or damp cloth to wipe the motor part to avoid short circuits or damage to electronic components.

Checking the connection status and wear degree of each component is an important part of maintenance. Before starting the machine each time, the operator should conduct a comprehensive inspection of the power cord, plug, switch and protective cover of the brushless angle grinder to ensure that the connection is firm and undamaged. At the same time, the wear of the grinding disc should also be carefully checked. If the edge of the grinding disc is found to be thinning or cracked, it should be replaced immediately to prevent breakage during operation, thereby causing safety accidents. In addition, it is necessary to regularly check the key components such as the bearings and gears of the motor. If looseness or wear is found, they should be tightened or replaced in time.

Lubrication is an important part of the maintenance of brushless angle grinders. For the moving parts of the machine such as the guide rails, sliders, bearings, etc., an appropriate amount of lubricating oil or grease should be applied regularly according to the requirements of the equipment manual. This can not only reduce friction and wear, but also ensure the smooth operation of the moving parts. When applying lubricating oil, the amount should be controlled. Too much or too little may affect the lubrication effect. At the same time, the replacement of lubricating oil should also be carried out regularly. It is generally recommended to replace the lubricating oil every 500 to 1000 working hours or every 3 to 6 months according to the frequency of use of the equipment and the working environment to maintain the good performance of the lubrication system.

Electrical system inspection is also a key part of brushless angle grinder maintenance. Operators should regularly inspect the electrical system to ensure that wires and cables are not damaged or aged, that electrical connections are firm, and that electrical components are functioning properly. Any problems found should be repaired or replaced in a timely manner to prevent electrical failures from causing safety hazards. During the inspection, the operator must ensure that the power supply is completely cut off and use insulating tools for operation to ensure their own safety.

Precision calibration is essential to maintain the machining accuracy of brushless angle grinders. Operators should regularly calibrate the machining accuracy of the machine, including the flatness of the work surface, the verticality of the grinding disc, and the runout. Professional measuring tools such as levels and dial indicators can be used for measurement and calibration to ensure that the machining accuracy of the machine meets industry standards.
