Pneumatic angle grinder is a type of grinding tool used for cutting and polishing fiberglass. It is a portable pneumatic tool that utilizes fiberglass for cutting and polishing, mainly used for cutting, grinding, and brushing metal and stone materials.
It mainly uses high-speed rotating thin disc grinding wheels, rubber grinding wheels, steel wire wheels, etc. to grind, cut, remove rust, and polish metal components. This equipment is suitable for cutting, grinding, and brushing metal and stone materials. Water should not be used during operations. Guide plates must be used when cutting stone. For models equipped with electronic control devices, grinding and polishing operations can also be carried out if suitable accessories are installed on such machines.
The common models produced by angle grinder manufacturers are divided into 100mm (4 inches), 125mm (5 inches), 150mm (6 inches), 180mm (7 inches), and 230mm (9 inches) according to the accessory specifications used. The small size angle grinder commonly used in Europe and America is 115mm.
How to install the cutting blades of the pneumatic angle grinder correctly? Is there a metal plate facing up or down? There are different opinions, some believe that facing outward with metal sheets is more reasonable, while others believe that facing inward is more reasonable. Which method is correct?
The side with the metal sheet should be installed facing outward. Why? Because the outward facing side will come into contact with the screw, there will be friction when tightening. The metal side facing outward can reduce friction and prevent the angle grinding disc from bursting. If the metal free side is facing outward and the screw is tightened, the friction between the angle grinding disc and the screw will be large, and the uneven surface may cause uneven stress, resulting in cracks on the angle grinding disc. During use, when the angle grinding disc rotates at high speed, it may burst and fly out, which is very dangerous, Therefore, it is safer to install the metal sheet facing outward.
In addition, the installation of saw blades in violation of regulations should be prohibited for pneumatic angle grinders, which is a very dangerous mistake! People who have used it all understand, beginners should not try! After the switch of the machine is turned on, even if it is released, it will not stop. Only by manually turning it off will it stop working. The speed of the machine is very high, therefore, when installing the saw blade to saw wood, the saw blade may get stuck, vibrate violently, etc., causing the angle grinder to grasp unstably and pop out.
