Have you seen power tools like angle grinders in your daily life? In general, we can still see this kind of tool in our daily life. Angle grinders are used in many places. For example, families or enterprises often need to do metal polishing and wood polishing. Angle grinders also need some accessories. Generally, angle grinder accessories have commutators, brackets, connecting rods, grinding wheels and so on. Let's get to know these accessories through some pictures of angle grinder accessories!

　 Precautions for angle grinder purchase
Â
　　 1. Function
Practical angle grinder, first of all from a practical point of view, it is best to be multi-functional, multi-function angle grinder generally needs to have three functions of grinding, polishing, cutting, and at the same time can be stone, wood, metal, Cutting, polishing and polishing of glass and other materials.
　 2. Appearance
The choice of appearance color is a personal hobby, but in terms of design, the shape is small and compact, and the angle grinding surface that is lighter to use is often more popular. It is not cumbersome to take out to work. Therefore, many engineers like to choose a light, compact and practical angle grinder, which will make it easier to use.
　 3. Power
Power is the heart of the angle grinder. The size of the power is a key factor that directly determines its working efficiency. The high-speed, high-power angle grinder is of course more practical, fast, and handy. In addition, the heat dissipation effect of the high-power angle grinder It will also be better, you can continue to work for a long time, there will be no burn-in phenomenon.
　　 4. Safety protection
When using the machine, the biggest point is to pay attention to safety. A good machine will be safer if it runs normally, but in addition to ensuring normal operation, it is also not enough, and also be careful of the damage of the noise and dust to the human body. Dust angle grinders are more conducive to health, and angle grinders with protective covers can also prevent dust from entering the machine and can extend the life of the machine.

Angle grinder failure and troubleshooting
Â
The angle grinder uses a series motor, which is characterized by two carbon brushes and a commutator on the rotor. The most common burn-out parts of this motor are the commutator and rotor winding ends. If the commutator burns, the carbon brush pressure is generally not enough. When the motor is working, if the current continues to be large, the carbon brush wears quickly, the carbon brush becomes shorter, the pressure becomes smaller, and the contact resistance becomes large. At this time, the surface of the commutator becomes very hot; If the winding part is burned, it means that the angle grinder has a great pressure on the workpiece when it is working, the friction force is very large, and the motor is in the overload state for too long. It is also because the current is too large.
The above is the picture of the angle grinder accessories and the related contents of the angle grinder purchase notes, faults and troubleshooting methods. The angle grinder is a tool that is often used by people, so its various accessories are also relative. Failures are easy to occur, we must master common failures and its solutions, in order to better carry out targeted maintenance for long-term use.
