1. Different definitions
Polishers, also known as grinders, are often used for mechanical grinding, polishing, and waxing. An angle grinder, also known as a grinder or a disc grinder, is an abrasive tool used for cutting and grinding FRP.
2. The working principle is different
The working principle of the polishing machine is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at a high speed. Because the polishing disc and the polishing agent work together and rub against the surface to be polished, it can remove paint pollution, an oxide layer, shallow the purpose of the mark. The rotational speed of the polishing disc is generally 1500-3000 r/min, mostly infinitely variable, and can be adjusted at any time according to needs during construction.
The angle grinder is to uses a high-speed rotating thin grinding wheel, rubber grinding wheel, wire wheel, etc. to grind, cut, remove rust, and polish metal components.
3. Different uses
Angle grinders have many uses and are commonly used by woodworkers, bricklayers, and electric welders. When the grinding wheel is installed, it is a small portable grinding wheel cutting machine, which can cut and grind small metal parts. It is indispensable for the production of metal processing such as stainless steel anti-theft windows and lightboxes.
The key to the operation of the polishing machine is to try to get the maximum polishing rate so as to remove the damaged layer produced during polishing as soon as possible. At the same time, the polishing damage layer should not affect the final observed tissue, that is, it will not cause false tissue.
4. Different classification
According to the function, the polishing machine can be divided into two types: dual-function industrial sanding/polishing machine and simple polishing machine. Angle grinders are classified into compact angle grinders and large angle grinders. Compact angle grinder: ultra-light, some with safety rebound switch configuration to meet the various requirements of novice operation; large angle grinder: powerful, suitable for difficult grinding and cutting operations.
