What Is an Angle Grinder?

Angle grinders, also known as angle grinders, are divided into two categories, pneumatic and electric. Only electric angle grinders are analyzed here. The electric angle grinder is used to grind, cut, remove rust and polish the metal components by using the high-speed rotating sheet grinding wheel, rubber grinding wheel, steel wire wheel and so on. The angle grinder is suitable for cutting, grinding and brushing metal and stone. Do not use water during operation. You must use a guide when cutting stone. For models equipped with electronic controls, grinding and polishing operations can also be performed if suitable accessories are installed on such machines.

Brushless angle grinder

After decades of evolution and development, the angle grinder has evolved from its original large size, bulky, and cooperative operation to two people, to today's compact and lightweight, strong power, single-person or even single-handed operation, which is a huge improvement. At the same time, the development of angle grinders has also played a huge role in the progress of the world industry. But the change is inseparable, the development of the angle grinder has been inseparable from one of the consumables-carbon brushes.

It is precisely because the disadvantages of the traditional angle grinder that need to replace the carbon brush cannot be solved, the brushless angle grinder came into being. It is gratifying that, after the unremitting efforts of Chinese industrial technicians, Fujian Jiayuan Power Tools Co., Ltd. has developed the first generation of brushless angle grinders and obtained national patents. After being put on the market, it has been widely welcomed by users. This machine does not require carbon brush transfer, and the rotor is made of solid silicon steel sheet, without metal coil winding, which is more durable.

1. The switch adopts a button type. If the power is turned on again when the power is cut off during work, the machine will not start on its own, reducing accidents and making it safer to use. 2. No carbon brush is needed, eliminating the impact of carbon brush powder on the body, saving the operator the trouble of frequently changing the carbon brush. And there is no spark generated by the friction between the carbon brush and the copper head, which plays an explosion-proof role and does not interfere with the surrounding circuit signals.

3. The brushless motor is assembled to eliminate the electric power consumption and friction resistance caused by the friction between the carbon brush and the copper head, and the power output ratio is increased by more than 20% compared to the traditional angle grinder.

4. The motor can maintain the rated speed during normal work, making the work more efficient, and there is no need to consider replacing the carbon brush at any time, and there is no need to worry about burning the rotor, and it is more efficient to use.

5. When the motor is started, the motor starts slowly and accelerates without tail-flicking, which makes the operation more comfortable. And because it is a slow start, it effectively reduces the instantaneous starting current of the motor, and effectively extends the life of the motor and related equipment.

6. The rotor of the motor is made of high-strength silicon steel sheet. It is not the traditional winding method of the rotor, and it will never burn the rotor.

7. Except for bearings and gears that require normal maintenance, the whole machine has no other wearing parts. Can minimize maintenance costs.
