Mainly divided into two types of handheld and desktop.
Square grinding machine, suitable for polishing corners and final polishing.
Round grinding is more efficient because it has the power of rotation in addition to eccentric vibration.
Hand-held belt machine, the most efficient, suitable for rough grinding of wood. Belt machine is generally 80 sandpaper.
The table sanding machine is suitable for grinding some small pieces of wood and making shapes. There are several types of hand-held wall grinders. If they are differentiated according to the operation mode, they can be divided into hand-held and long-handled ones. One type is not long, which is relatively small. However, there is a disadvantage that the working range is relatively small. You need to climb to a high place when you are grinding a high position. The model with a long handle, although the size is relatively large, is relatively inconvenient to carry, but his advantage comes out when working, because this with a long handle, when grinding, the scope of work is relatively large It does not require frequent moving positions, which helps to improve work efficiency. And when you polish such as high places and roofs, you don't have to climb high, it's very convenient, and you can save energy.
